Do you want to lose “serious” weight? Intermittent fasting is a method you should check out, says one expert. Eric Berg, DC, is a doctor and chiropractor who specializes in keto and intermittent fasting. He regularly shares videos on how to lose weight with time restricted eating and has amassed a whopping 12.1 million YouTube subscribers. In a viral video he talks about “doing intermittent fasting for some serious weight loss.”


There Are Many Pros to Intermittent Fasting, he Says

“There are many magical and very cool things about intermittent fasting that you need to be aware of,” he says at the start of the video. “First of all, it's extremely cheap. In fact, it's free. In fact, you'll save money. It's easy and it doesn't require any effort. You're not doing something, you're just avoiding something. You're avoiding food. Fasting gives you a lot of extra time so you're not constantly cooking all day. Fasting will help you live longer. It makes you smarter because it improves your cognitive function. It elevates your mood and lowers your risk for many diseases. So there are a lot of benefits.”

You Also Don’t Have to Spend a Lot of Time or Money on Food

He also adds that “because you're not cooking all day, you're gonna have a lot of extra time on your hands. So you're gonna have to find something to do. And because you're not spending all this extra money on food, you'll have a lot of extra money that you have to figure out what to do and that's a problem.”

Intermittent Fasting Is Not a Diet But a Pattern of Eating

“Intermittent fasting is not a diet, it's a pattern of eating and not eating,” he continues. It's putting you in the driver's seat of when you tell your body it can eat and when it needs to avoid eating.” He points out that “so many times you'll get a very unhealthy answer if you ask your body what it's in the mood for. This especially applies to when your blood sugars are a problem because if your blood sugars are too low or too high, you're gonna get an insane answer. So it's kind of like you being in the backseat of a car and having some insane driver drive you around. This is not a good situation because you're no longer in control and unfortunately food has been controlling you your entire life. In fact, our whole existence revolves around food. So doing it in the fasting starts to put you in control over this insanity, which is a very powerful thing for you personally with your willpower, with your self discipline, and especially for your health.”

Every Time You Eat, You Trigger insulin

“The one thing that you need to know about intermittent fasting is that every time you eat, you trigger insulin. So insulin not only increases with sugar and carbs, but also from just eating in general. So the less frequent you eat, the less insulin you're gonna trigger and the more benefits you're gonna have,” Dr. Berg continues.

Bodies Have Evolved Over Time to Not Eating

“Our bodies have evolved over a very long period of time to not eating, because long ago

food wasn't very available. So our bodies have adapted and developed all sorts of very amazing genetics for surviving without food. And when I'm talking about survival, I'm talking about those genes that are survival genes, repair genes, disease genes turning off. Like for example, cancer turns off when you fast. So all sorts of fascinating survival things related to your DNA get activated when you start fasting,” he reveals.

Step 1: Stop Snacking

The average person who is consuming three meals a day with snacks in between meals, “like six meals,” will be getting “a lot of spikes of insulin through the day and their body is suffering immensely from this,” he says. “So the first thing to do is to stop snacking. That's step number one. So then you just have three meals a day. And so then you do that until you're comfortable.”

Step 2: Skip Breakfast

“The next stage is to skip your breakfast or that first meal,” he says. “So in other words, when you wake up in the morning because you're not snacking, you're not really gonna be hungry, especially if you're doing keto,” he continues. “So let the lack of appetite in the morning dictate whether you eat or not because the underlying principle is don't eat unless you're hungry.”

Step 3: Push Back the Timing of Your First Meal

“So you wake up, you're not hungry, don't eat, go as long as you can until your first meal. Okay? So you work up to your first meal being let's say at noon, right? Lunchtime. So let's say you're eating at 12 and six. That gives you 18 hours of fasting, okay? You have this window of eating, which is six hours, and then you have 18 hours of fasting,” he continues.

Step 4: Add Fat at the End of the Meal

“Now to add a little help to the situation, if you add more fat at the end of the meal, whether it's avocado, handful of nuts like macadamia nuts or pecans or any type of fat, that will allow you to fast longer in, get into the next stages easier,” he says.

Step 5: Add Vinegar

“As a side note, there's a lot of other things we can do to improve this situation, especially with blood sugars as well. For example, if you eat a big salad as the first thing that you eat in your meal and you put olive oil dressing on an extra virgin olive oil and you put some balsamic vinaigrette or even apple cider vinegar on that salad, you're gonna create a really cool effect with your blood sugars,” Dr. Berg claims.

Step 6: Eat a Lot of Fiber

Next, make sure “you're eating a lot of fiber,” he says. Fiber buffers. Insulin fiber is the only carbohydrate that won't trigger insulin. The oil in the extraversion. Olive oil is also another thing that really won't trigger insulin that much, if at all. And the oil helps you extract some of the fat soluble nutrients from that salad. And I'm talking about the phytonutrients, which are fat soluble. So you get the benefit of that vinegar, whether you do outside of vinegar or balsamic vinaigrette gives you a very potent antidiabetic effect 'cause it helps you lower blood sugars as well as insulin. Yu can also add some cinnamon to your diet, “like whether it's in that drink or in something else, cinnamon is another potent thing to help your blood sugars,” he says.

Step 7: Add Vitamin D

He also recommends getting vitamin D. “It is another thing you can add to this mix and just get more sun that will help you,” he says.

Step 8: Fast for 18 Hours Until You Get Comfortable

At this poing you're at the stage where you're eating two meals a day and during a six hour window. “Now ideally you wouldn't wanna snack within that window, but if you had to, that would be the time to snack, not in the fasting window, because we want that 18 hours of just pure fasting. So you're gonna do this for a period of time until you get comfortable,” he says.

Step 9: Shift to a 20 Hour Fasting Period, Making Meals Closer Together

“As you get used to it, then you wanna take it to the next step, especially if you wanna lose more weight,” he says. “What we wanna do is we wanna take those two meals and get 'em closer together, like within a four hour period. So let's say for example, you get up in the morning, you fast all the way to noon, you're still not hungry, you keep going, and then you fast until two o'clock, you have your first meal and your second meal at six. So now we have a four hour eating window and a 20 hour fasting window, which is gonna be even better. And you're gonna see more fat loss.

Step 10: Move to OMAD

After a “couple weeks until you feel comfortable,” he recommends switching to one meal a day, AKA OMAD. “Now what's happening is we collapse these two meals together as one, one large meal. Make sure it's nutrient dense and it's healthy and that's all you're gonna eat. Now, of course, you're not gonna be able to eat the same calories as you would when you're doing two meals, but the benefit of this is not really that you lower your calories, it's the fact that you're fasting for 23 hours. That's gonna produce even greater benefits for your immune system, for your brain, for your anti-aging, for your repair.”

Step 11: Eat Your Meal No Later Than 3:00 PM

He also recommends adding “another tweak” to the OMAD plan. “It's just a slight change that could make a big difference with your sleep and even a greater improvement in your blood sugars and insulin and insulin resistance. And that would be having that last meal no later than 3:00 PM,” he recommends. He points out that “the later that you eat, apparently that can interfere with your sleep cycles and that can stir up certain genes that are related to food and that can inhibit your sleep. So you might wanna just try this, eat a little bit sooner, make it a big meal right in the middle of the day, like maybe two or three, and see if you don't sleep a lot better.”

Step 12: Add Exercise or Keto to the Mix

He says there are a “lot of other things” you can do to improve your result, like adding exercise. “We can also add the healthy version of the ketogenic diet, which I promote, which just is higher quality ingredients and more nutrients in that meal.”

Step 13: Interject Periodic Prolonged Fasting

The last phase of fasting is really interjecting some periodic prolonged fasting episodes. So you can add in like once a week or once every two weeks of 48 hour fast or even a 72 hour fast. It's a three day or even 128 hour fast, which is a five day fast, which could be unbelievable for your immune system and especially if you wanted to prevent cancer because as soon as you start fasting for long periods of time, you are literally destroying cancer in your body,” he claims.

Start Slow and Gradually Improve Your Fasting, He Says

The bottom line? He recommends starting slow with intermittent fasting and “gradually improving your fasting to the point where you're really doing it for some serious weight loss and health benefits.”

Isis Kellier is a diet and fitness influencer who regularly shares videos on her channel about how she lost weight fast and got into the best shape of her life. In one TikTok video she reveals how she dropped an average of 2.5 pounds a week by making a few simple changes to her diet and fitness routine. “How I lost 15 pounds in six weeks,” she starts the clip, going on to reveal her secrets. We also asked The Diet Diva, Tara Collingwood, MS, RDN, CSSD, LD/N, ACSM-CPT, a Board Certified Sports Dietitian, to weigh in on her tactics.


1. Intermittent Fasting

Intermittent,Fasting,Hungry,dietShutterstock

The first thing Isis did? Intermittent fasting, or “OMAD,” she reveals, which stands for “one meal a day. “The Lightly intermittent fasting app helps to keep everything on track,” she added. In another video she details what she eats in a day, starting at 2:00 pm with two glasses of green juice followed by a bowl of fruit. For her main meal of the day, “dinner,” she eats at 4:00 pm and enjoys spicy vodka pasta with a grilled chicken breast on top. At 5:30 pm she drinks two Premiere Protein shakes.

2. Expert Weighs in on OMAD

“It sounds like she is only eating in a less than 4 hour window which is a very small eating window,” Collingwood notes. “I like that she has antioxidant rich green juice and fruit, but that is not really a ton of produce or fiber. When you eat most of your produce as juice, you are missing out on a lot of fiber which is really important for gut health and keeping the microbiome in check.” As for protein, she is likely meeting her requirements with the grilled chicken, “not sure size but let’s assume 4 oz = 28 grams of protein and two premier protein shakes at 30 grams each gives her another 60 grams to push her over 80 grams for the day,” she notes. “However, two highly processed protein shakes are not really providing the quality of food we like for overall good health. They do have a lot of vitamins and minerals added to them, which she needs because she is not eating very many calories or a variety of foods.” She is happy to see some carbs in the pasta, “but vodka sauce does not really provide much nutritional value,” she adds. “ Marinara would be much better with the antioxidants and nutrients in tomatoes.” Overall Collingwood is concerned about her low calorie intake. “Again, I don’t have exact portion sizes but I estimate this to be about 1000-1200 calories.”

3. 30-60 Minutes of Cardio Daily

Next up? “30 to 60 minutes of cardio daily,” she reveals. In the other video she reveals that she does “fasted cardio” in the morning prior to her first meal.

According to Collingwood, 30 to 60 minutes of cardio “is great,” she says. However, “if she is doing this in the morning and not getting any calories until 2 PM (and that is very few with the green juice and fruit and no protein) she is leaving her body susceptible to poor recovery, injury risk, dehydration, and low energy,” she points out.

5. Calorie Deficit

Calorie,Counting,Calculator.,Diet,.Shutterstock

Her final secret to losing 15 pounds in six weeks? Maintaining a “caloric deficit,” she says. The basic math of calories in vs calories out is caloric deficit which is necessary to lose weight, Collingwood agrees. “But you can create a caloric deficit in many other more healthy ways that include fueling the body in more regular intervals, feeding more nutritious foods, and having more balance.”

6. Bottom Line: Is a 15-Pound Weight Loss in 6 Weeks Realistic?

Weight,Scale,scales,loss,diet,health,feetShutterstock

Collingwood and most experts agree that a healthy weight loss rate is typically one to two pounds per week. “15 pounds in 6 weeks is a bit higher than that,” Collingwood points out. “It all depends on how much weight someone has to lose. If you have 100 pounds you lose, it will come off faster initially. If you only have 15 pounds to lose, the weight will come off more slowly.

In general, the faster it comes off, the more likely there is a higher proportion of muscle coming off vs a majority of fat tissue.”

We've consulted with our team of licensed nutritionists and dietitians to bring you informed recommendations for food products, health aids and nutritional goods to safely and successfully guide you toward making better diet and nutrition choices. We strive to only recommend products that adhere to our philosophy of eating better while still enjoying what you eat.

Can you lose weight fast and keep it off? Yes, says one top health and fitness expert. Jillian Michaels is a fitness expert and star of The Biggest Loser. In a recent video, she reveals that it is possible to lose weight fast. At the start of the clip, Michaels points out that “nobody ever” says, “I want to lose weight slowly.” And there’s nothing wrong with that. “There's a lot of conflicting information about whether it's safe, whether you lose weight too quickly, and whether you will have loose skin. And so here's the deal. You can lose weight quickly, and you can lose weight quickly, safely, depending on how you lose it,” she maintains.


Most People Go About Rapid Weight Loss the Wrong Way

According to Michaels, most people go about rapid weight loss the wrong way. “To lose weight, we have to create a calorie deficit. You've gotta eat less food than your body is burning in a day,” she points out, noting that a pound “is about 3,500 calories,” so if you wanted to lose two pounds a week, you would need to burn a thousand extra calories a day. “This is where diets get dangerous,” she says.

Starving Yourself Throws Off Your Hormones

She explains that when people diet and do “things like fasts and cleanses or dramatic calorie reduction,” they are usually depriving their body of nutrients. “There's a reason people talk about yo-yo dieting,” she says, explaining that you will lose weight, but gain it all back. “When you starve the body, you're telling your body, ‘Oh my god, food is really scarce’” which then shifts your hormone balance, “to store more fat and I'm going to cannibalize my own healthy tissue because I need fat to insulate my vital organs,” she says.

It “Messes Up” Your Metabolism

“The bottom line is it messes up your metabolism, and when you start eating normally again, if you even go back to normal, because a lot of times with these dramatic diets, there's a huge pendulum swing the other way, you've now damaged your metabolism,” she says. “You're going to put the weight you lost on and then some.” This is yo-yo dieting. “Plus, when we starve ourselves, we've lost lean tissue, lean body mass, which also compromises your metabolism. So it's this really dangerous, bad cycle.”

You Also Won’t Be Able to Exercise

“Plus, how much are you really going to lose? So what are you going to run on 500 calories a day? Well, you're certainly not exercising on 500 calories a day. I mean, and even if you were, what did you burn? 2,000 calories a day?” she points out. This might help you lose three pounds a week, but you will “starve your body and do a ton of damage. Like you can't starve the weight off. It's just not possible,” she says.

If You Want to Lose Weight Rapidly, You Need to Exercise

The answer to losing weight fast, according to Michaels? “Rapid weight loss comes from exercise,” she says. “If you're maintaining your weight, it's going to be all food. If you don't overeat, you're not going to get any bigger, okay? If you're trying to lose weight, it's like 80% exercise because you can't starve it off,” she says. “It requires more energy to move your body, period,” she adds, noting that “certain fitness techniques” are better than others for energy. They include HIIT, plyometrics, free weights, and metabolic circuits.

Women Should Never Drop Below 1,200 Calories and Men, 1,500

“If you want to lose weight quickly and safely, this is the absolute bottom line for women. Do not go below 1200 calories and you can have unlimited green vegetables. You gotta count the stuff you put on them, but you can eat unlimited greens because the reality is that you're going to get more fiber, more phytonutrients, and it almost requires as much energy for you to break down and metabolize that food than the amount of energy that's actually in the food. As a man, I never would go below, never would go below 1500 would not do it,” she says.

You Can Do 4 to 5 Hours of Higher Intensity Exercise a Week

She explains that you can do four to five hours of higher intensity training a week. “I don't mean four to five hours of the craziest techniques like HIIT and this and that. You can do like a good hour of resistance training in circuits with free weights, multiple muscle group exercises, squat thrusters, things of that nature. Pull ups, pushups that are going to burn more calories. You can work HIIT intervals into those sessions, four to five hours of intensity a week maximum.”

And, the Rest of Your Exercise Should Be Lower Intensity

“The rest has gotta be low intensity activity,” she says. This includes hiking, walking, biking, swimming, “so that you're not over training, you're not overstressing, you're not putting your body at risk of injury, you're still giving your body enough recovery time,” Michaels continues. “I always call that kind of low intensity cardio, the bread and butter of extreme weight loss.”

If You Want to Lose Weight Fast, Do as Much Lower Intensity Cardio As You Can

“If you want to lose a lot of weight, it's a lot of that low intensity cardio, a lot of it. And that's where it's not realistic, but it is safe. It is okay,” she says. “The extremes, that's where things get dangerous.”

And, Here Is the Truth About Loose Skin

As for loose skin, “contrary to popular belief, it doesn't matter how quickly you lose weight. If you've got loose skin, you've got loose skin and that's it,” Michaels says. “The skin is an organ. How it rebounds after weight loss has a lot of different factors and components, one of them being genetics.” And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.

Can you actually lose 25 pounds in a month? According to one weight loss influencer, the answer is yes. Rosa Charice (@rosacharice) has amassed nearly 400,000 followers on TikTok by sharing about her massive and rapid weight loss. In one video she reveals a significant secret to dropping tons of weight fast. “If you are trying to lose weight simply with a calorie deficit alone, and it isn't working for you, then you should try this instead. I was able to lose 25 pounds in just 30 days,” she says. Here is everything you need to know about how she did it.


Intermittent Fasting Helped Her Lose Weight

Rosa reveals that restricting her eating hours was instrumental in her weight loss journey. “I was able to lose weight so fast by intermittent fasting and not even restricting myself,” she says in the clip. “I didn't even have to do much tracking after that.”

She Used an Intermittent Fasting App

She added that she used a fitness app to help her lose weight. “One of my favorite apps at the moment to use for weight loss or weight management is called Label. I have previously recommended this app to help you count calories, but they also recently just added a fasting feature,” she says, explaining that they offer one-on-one coaching through your intermittent fasting journey, “so you feel like you have companionship and guided support,” she says. “They also give you specific recipes you can pair with intermittent fasting, so you don't have to count calories. And they also give you a basic to-do list or even instructions to help make intermittent fasting easier for weight loss.”

Does Intermittent Fasting Work?

Intermittent,Fasting,Hungry,dietShutterstock

Intermittent fasting " prolongs the period when your body has burned through the calories consumed during your last meal and begins burning fat,” explains Johns Hopkins Medicine. However, according to Chris McMahon, a nutrition and fitness coach, “there's nothing magical” about fasting because weight loss boils down to calories in versus out. However, “if you're someone with a hectic schedule or you're just not hungry in the morning and you don't tend to get hungry until 10 or 11,” there isn’t anything wrong with fasting. Still, it won’t “suddenly transform your body or reset your aging clock or your biological clock,” he says. “All you're doing is just cutting some of your calories out.”

💪🔥Body Booster:Try intermittent fasting if it fits your schedule. Remember, weight loss depends on a calorie deficit, not fasting alone.

Are you already on the intermittent fasting bandwagon, but can’t seem to lose weight? You might be making a critical mistake, claims one expert. Dr. Morgan Nolte, PT, DPT, GCS, is a board-certified clinical specialist in geriatric physical therapy and the founder of Zivli. In a viral YouTube video she discusses the most common missteps people make while practicing time restricted eating. “If you are using intermittent fasting to lose weight or get healthy, be sure to avoid these 10 common intermittent fasting weight loss mistakes,” she says in the video. “The goal of this episode is to help you avoid 10 common intermittent fasting weight loss mistakes that I've made and that I see my clients make, especially beginners just getting started with fasting.”


Keep in Mind That When You Start on the Weight Loss Journey, Your Body Might Take Time to Adjust

“When you're trying to lose weight or get healthy, there are so many forces working against you,” she says. “Your body likes the status quo and doesn't want to change.”

Intermittent Fasting Is a Great Tool to Lower Insulin and Get Your Body Into Fat Burning Mode

“Habits are hard to break, but using intermittent fasting is one of the best tools in your weight loss toolbox because when you don't eat, your insulin stays low. Insulin is your fat creation and storage hormone. So if you want to get into fat burning, intermittent fasting is a great tool to lower insulin,” she continues.

If You Have Insulin Resistance There Is More to the Equation Than Just “Eat Less, Exercise More”

“When insulin is too high for too long, you may develop insulin resistance, which makes losing weight harder. It's also a root cause for type two diabetes, heart disease, and dementia. So living a low insulin and inflammation lifestyle is key to better health and keeping the weight off,” Dr. Nolte continues. “It takes a more specific and targeted strategy than just eat less, exercise more to lose weight with insulin resistance.”

Here Is Who Should Try Intermittent Fasting

,Woman,Weight,Machine,To,Balance,Weigh,scales,weigh, loss, diet,thinking, puzzledShutterstock

Who should try intermittent fasting? “If you've been at a weight loss plateau or are just getting started and maybe you've lost some weight but you're terrified to regain or you just have a few extra pounds to lose, intermittent fasting can be a helpful strategy for you,” she maintains.

Keep in Mind That Intermittent Fasting Is Basically Time-Restricted Eating

She also wants to “take any drama or fear” out of the term intermittent fasting. “Everyone is already intermittent fasting. Anytime you are not eating, you are intermittently. Fasting when you're sleeping is a great example. So for that reason, I prefer the term time-restricted eating or feeding because it's more descriptive of what you're doing. You're shortening your eating window so that more time of your day is spent fasting to lower insulin.”

Everyone Should Fast for 12 to 14 Hours a Day

“I recommend everyone fast for at least 12 to 14 hours per day. That would be considered a baseline level of intermittent fasting, and in my opinion is ideally just part of everyone's lifestyle unless they have a medical reason not to,” she says.

Moderate Intermittent Fasting Is 14 to 24 Hours Fast and Anything Longer, Advanced

“I consider moderate intermittent fasting, anything from about 14 to 24 hours,” Dr. Nolte says. She defines “more advanced fasting” as “anything longer than a day.” She recommends “moderate intermittent fasting because we want you to lose weight how you're gonna live the rest of your life and not necessarily view fasting as a diet,” she says.

Talk to a Doctor Before Extending Your Fast

“There are good medical reasons for advanced or extended fasting, but they may require more direct medical supervision depending on your health conditions,” she continues. “While intermittent fasting is the most powerful tool in your weight loss toolbox, it is still just one tool.”

Mistake 1: Overeating or Eating Too Much Processed Food

“What you eat and how much you eat is very important too. So mistake number one is overeating or eating too much processed food,” Dr. Nolte reveals. “The golden rule of nutrition is to eat real unprocessed food. Whatever dietary pattern you ascribe to the golden rule still applies and will make that nutritional pattern healthier.”

Mistake 2: Fasting Too Long

I'll eat you tiny pea! Weight loss concept. Close up photo portrait of mad lady's eye looking at small one pea on large big plate on tableShutterstock

“The second major mistake, especially for those who want to make time restricted eating part of their lifestyle is they fast for too long,” reveals Dr. Nolte. “Starting out, they shock their brain and body and develop a restriction mindset that leads to overeating or binging.” Instead, “gradually increasing your fasting window versus going from say, a 10 hour fasting window to a 16 hour fasting window in one day,” is the way to go. “Gradually increasing by 30 to 60 minutes will be easier for both your brain and your body to adjust, but before you advance your fasting window, refer to my first point about learning how to properly fuel your body so that when you are fasting, you're not as hungry.”

Mistake 3: Underhydration

, mature,Middle,Age,Man,Drinking,Glass,Of,Water,Sitting,On,SofaShutterstock

“Speaking of hunger, that brings me to the third mistake of under hydration. Much of the water we consume in a day comes during meals to help us chew and swallow our food. We also get some water from the food that we eat. So if you're not eating, it will be especially important to hydrate,” she explains. “Aim for at least half your body weight in ounces of water per day. Ideally, your urine is clear or light yellow. Now, small amounts of caffeinated beverages like coffee or tea, like less than four to 500 milligrams would technically count towards your water intake.”

Mistake 4: Drinking Alcohol or Sweetened Beverages – EvenThose with Non-Nutritive Sweeteners While Fasting

“The fourth intermittent fasting mistake is drinking alcohol or any sweetened beverage, whether with sugar or non-nutritive sweeteners, even the healthy ones, during your fasting window,” she says. Sugary beverages, alcohol, and many zero or low calorie drinks like ice, Coke Zero, really anything sweet, will trigger the hypothalamic region in your brain to make you think that calories are coming in. The hypothalamus then sends a signal to your pancreas via your vagal nerve that says, ‘Hey, you better get some insulin pumped out because we have some sweet stuff coming in.’ Then the insulin gets pumped out, but there's not really a direct rise in the glucose because you didn't actually eat any sugar or calories. So insulin pushes glucose already in your bloodstream into your cells, which lowers blood sugar. This drop in blood sugar sends a signal to your brain to increase your hunger, which is not something that we wanna do when we're fasting.

Mistake 5. Not Having Electrolytes While Fasting

“Piggybacking on the hydration mistake is mistake number five, which is not having electrolytes when you're fasting,” says Nolte. “This was a mistake that I made for a long time, but finally started taking them when I felt like my muscles were taking longer to recover from exercise than what I wanted.” She recommends unflavored electrolytes with no added sugar or sweeteners.

Mistake 6: Fearing Exercise

“Mistake number six is fearing exercise when you're fasting,” says Nolte. “This is one that's very personalized based on the level of intensity of your workouts and body composition goals.” She recommends taking exercise one step at a time. “Start with where you're at and know that any movement is better than none. But for optimal mitochondrial health and fat burning an hour of zone two aerobic exercise several times a week can be great. If you're struggling through your workouts, try including electrolytes in your water during and after exercise.”

Mistake 7: Eating Too Much Starch and Sugar During Your Window

Pop,Tarts,Toaster,Pastry,processed,food,sugarShutterstock

“Mistake number seven is eating too much starch and sugar during your eating window,” says Nolte. “To maximize the benefits of intermittent fasting for weight loss and fat burning, it's important to reduce starches and sugars in your diet. Starches and sugar have the biggest insulin response of all three macronutrients. Now remember, the whole goal here is to live a low insulin and inflammation lifestyle. There are essential proteins and fats, and I'd argue that fiber is essential too, but there are no essential starches or sugars. So if you're at a plateau, do a nutrition audit and check to see how you could increase your portions of protein, fat, and fiber from whole foods and reduce the portions of starches and sugar.”

Mistake 8: Fasting at the Wrong Time of Your Menstrual Cycle

“Now, mistake number eight is fasting at the wrong time of your menstrual cycle,” Nolte continues. “If you're a woman still menstruating, the best time to experiment or start fasting is the week of your period up to ovulation. So about days one to 14, you won't wanna do longer fasts during ovulation or the week before your period.”

Mistake 9: Fasting When You’re Not Sleeping Well

Mistake number nine is fasting when you're not sleeping well. “Sleep deprivation will increase your hunger hormone, ghrelin and make fasting harder, not something that we want,” she says. “If you're not sleeping at least seven hours a night, I'd focus on improving your baseline nutrition and sleep before starting anything longer than a 14 hour fast. It will just be easier and you're gonna see better results.”

Mistake 10: Being Impatient and Giving Up Too Soon

“I've saved the best mistake for last, and that is being impatient about your results and giving up too soon,” she says. “There is no entitlement in weight loss. I know that for some, when you fast, you feel like you deserve to see results on the scale right away, and you might because fasting lowers insulin faster than anything else. And when your insulin is lower, you'll excrete more water. So the first bit of weight you lose may be water weight. The weight loss will likely slow down, and that is 100% normal expected. And okay, we've got to get over the instant gratification mindset If our aim is long-term weight loss and better health because that mindset is not serving you.”

Tackle One of These at a Time

“No need to tackle all of these at once as that often leads to overwhelm, like you're taking two steps forward and then one step back,” Nolte concludes. “Instead just pick one and narrow your focus, your efforts will be way more effective that way.”

Let's face it—hitting 40 comes with some unwelcome surprises for most of us. Suddenly, those extra pounds seem to appear out of nowhere, and the weight loss strategies that worked in your 30s just don't cut it anymore. But before you throw in the towel, here's some good news: certain foods can actually help kick your metabolism back into gear.

We've dug into the latest research from top medical institutions and talked to leading experts to uncover the foods that can help you burn fat after 40. No fad diets or miracle pills—just real, science-backed nutrition that works.

Why Your Body Changes After 40 (And What to Do About It)

"It doesn't matter what you've always done before—that doesn't fly anymore," saysDr. Monica Christmas, who runs the menopause program at University of Chicago Medicine. She's seen countless patients struggle with the same story. "When your hormone levels drop, your body starts losing muscle, and that means you're burning fewer calories even at rest."

Dr. Robert Creel from Cleveland Clinic puts it bluntly: "Your muscles are like engines that burn fuel. The more muscle you have, the more calories you burn just sitting on your couch." After 40, maintaining that engine becomes job number one.

Ready to refuel your body's fat-burning potential? Let's dive into the foods that can help.

1. Lean Proteins

Think of protein as your body's ultimate fat-fighting fuel. Chicken, fish, lean beef, tofu—they all help preserve precious muscle mass that naturally diminishes after 40.

Here's something fascinating from Harvard researchers: your body burns 15-30% of protein calories during digestion, compared to just 5-10% for carbs and a measly 0-3% for fats. That extra calorie burn happens automatically, just by choosing protein-rich foods.

Dr. Roger Blumenthal from Johns Hopkins Medicine loves to remind his patients: "Your muscles are literally the engines that burn calories in your body. Feed them right, and they'll work for you around the clock."

How to enjoy it: Start your day with eggs and veggies, grab a grilled chicken salad for lunch, or try a palm-sized portion of wild salmon for dinner. Aim for 25-30 grams of protein at each meal to keep your metabolism humming.

2. Greek Yogurt

That creamy container of Greek yogurt in your fridge? It's actually a secret weapon against stubborn fat. With double the protein of regular yogurt and a healthy dose of probiotics, it's a one-two punch for your metabolism.

Dietitians at the Cleveland Clinic have found that the probiotics in yogurt help balance gut bacteria—which might be even more important after 40, when digestive efficiency naturally declines. Plus, the calcium in Greek yogurt has been linked to lower levels of belly fat, which becomes more of an issue with age.

How to enjoy it: Skip the sugary flavored versions and go for plain. Add a drizzle of honey and berries for a satisfying snack, use it as a sour cream replacement, or blend it into smoothies for a protein boost.

3. Fatty Fish

Mackerel,Fish,Grill,foodShutterstock

Salmon, mackerel, and sardines aren't just delicious—they're packed with omega-3 fatty acids that fight the inflammation that often increases after 40.

Scientists at the NIH discovered something remarkable: omega-3s can increase your resting metabolic rate by up to 14% and boost fat burning during exercise by a whopping 27%. Talk about a winning combination.

"When we look at heart health after 40, fatty fish really shines," says a cardiologist at Johns Hopkins Medicine. "The same omega-3s that protect your heart are also helping reduce that internal inflammation that makes weight loss so difficult in midlife."

How to enjoy it: Aim for two servings of fatty fish weekly. Try simple grilled salmon with lemon or sardines on whole-grain toast for lunch, or add mackerel to your favorite salad.

4. Whole Grains

Forget what you've heard about cutting all carbs. Your body after 40 still needs them—just the right kind.

Researchers at Cleveland Clinic found something surprising when they studied whole grains in people under 50: those eating whole grains instead of refined ones had three times better blood pressure readings. That's huge for metabolic health, which directly impacts how well you burn fat.

"Whole grains provide steady energy without the crashes," explains a nutrition researcher at Cleveland Clinic. "After 40, those energy crashes can trigger stress hormones that promote fat storage, especially around the middle."

How to enjoy them: Start your day with steel-cut oats, swap white rice for brown or quinoa, and choose whole grain bread with at least 3 grams of fiber per slice.

5. Eggs

Eggs have made a major comeback in nutrition circles, and for good reason. They're nature's perfect little package of high-quality protein, vitamin D, and choline—a nutrient that helps your body burn fat and is often lacking in our diets.

Research from the University of Connecticut found something interesting: people who eat eggs for breakfast naturally eat fewer calories throughout the day. The protein and healthy fats keep hunger hormones in check—a major win when battling age-related weight gain.

How to enjoy them: A two-egg breakfast with veggies and a slice of whole-grain toast makes a perfect metabolism-boosting morning meal. Hard-boiled eggs also make great portable snacks when you need something satisfying on the go.

6. Legumes

Lentils, black beans, and chickpeas might not be the sexiest foods in your kitchen, but they pack a one-two punch against age-related weight gain: fiber and protein.

Harvard researchers have found that this combination helps stabilize blood sugar—crucial after 40 when insulin resistance becomes more common. When your blood sugar stays steady, you avoid the energy crashes that lead to cravings and overeating.

How to enjoy them: Toss chickpeas into your salad, add lentils to soups, try bean-based pasta, or whip up a quick lunch of black bean and avocado wrap.

7. Green Tea

Green tea isn't just a soothing ritual—it's loaded with compounds that give your metabolism a gentle nudge in the right direction.

NIH research shows that the catechins and caffeine in green tea work together to boost metabolism beyond what caffeine alone can do. While no single food or drink works miracles, green tea drinkers consistently show better results in weight management studies.

How to enjoy it: Replace your afternoon coffee with green tea, or start your morning with a cup. For maximum benefits, brew your own rather than buying bottled versions with added sugar.

8. Nuts and Seeds

"They're calorie-dense, but that doesn't mean you should avoid them," says Harvard Health about nuts and seeds. In fact, people who regularly eat nuts tend to be leaner than those who don't—seemingly contradicting their high calorie count.

The protein, fiber, and healthy fats in almonds, walnuts, and flaxseeds create the perfect satisfied feeling that helps prevent overeating. Plus, they require more energy to digest than many other snacks.

How to enjoy them: Stick to about 1/4 cup (a small handful) daily. Add a tablespoon of ground flaxseeds to your morning smoothie, sprinkle chopped walnuts on your salad, or grab a small handful of almonds for an afternoon snack

9. Leafy Greens

You've heard it your whole life: eat your greens. After 40, this advice becomes even more crucial.

"When we look at the most successful weight managers after midlife, high vegetable intake is always a common factor," notes a dietitian at Mayo Clinic. "The fiber fills you up, the nutrients support metabolism, and the volume satisfies hunger cues—all with minimal calories."

How to enjoy them: Start meals with a simple salad, add spinach to smoothies (you won't taste it), wrap sandwich fillings in large lettuce leaves instead of bread, or roast kale with a little olive oil for a crunchy snack.

10. Water

It sounds too simple to be true, but researchers at the University of Utah discovered that properly hydrated people burn more calories than those who are even slightly dehydrated. In fact, dehydration can slow metabolism by as much as 3%—and many of us walk around mildly dehydrated without even realizing it.

After 40, our thirst signals often become less reliable, making conscious hydration even more important.

How to enjoy it: Start the day with a full glass of water, keep a refillable bottle with you, add fruit slices or herbs for natural flavor, and eat water-rich foods like cucumber, watermelon, and strawberries.

Putting It All Together: Your After-40 Eating Strategy

Here's what Dr. M. Regina Castro from Mayo Clinic tells her patients who are struggling with midlife weight changes: "You need to reset your body's metabolic expectations through consistent, gradual changes. Your meals should feature lean proteins alongside fruits and vegetables—this combination supports your changing metabolism."

Cleveland Clinic experts have another crucial tip: when you eat matters too. "Your body processes the exact same food differently depending on the time of day," they explain. "After 40, eating earlier in the day tends to work better for metabolism than late-night meals."

Dr. Christmas cuts right to the chase with her patients: "You can't exercise your way out of a bad diet, and you can't eat your way out of being inactive. After 40, you need both pieces working together."

These 10 foods aren't magical—they work by supporting your body's changing needs after 40. They help maintain muscle mass, reduce inflammation, stabilize blood sugar, and keep your energy levels steady—all crucial factors in maintaining a healthy weight in midlife and beyond.

The best news? They're delicious, accessible, and can easily become part of your everyday eating. No extreme diets or bizarre superfoods required—just real, wholesome nutrition that works with your body, not against it.

It’s important to remember that weight management after 40 is about more than just food. Regular strength training, quality sleep, stress management, and staying hydrated all work together with good nutrition to keep your metabolism running at its best.

We spend hours hunched over desks and slouched on couches, rarely challenging our bodies to move the way they naturally should. Digital coachLaura Try, with over 170,000 YouTube subscribers, invites us to reclaim a fundamental human position that many of us have lost: the deep squat. "Modern-day living and this chair-filled life is causing some of us to move less and with less range of motion," Laura explains. Try this simple test to discover where your mobility stands—you might be surprised at what you learn about your body.

What Is the Deep Squat Test?

The deep squat test challenges you to hold a deep squat position for as long as possible, ideally reaching the full 10 minutes. "The deep squat, otherwise known as the Asian or primal squat, is meant to be a resting position," Laura says. The challenge requires no equipment and can be done anywhere. It's not just about holding the position but assessing how your body responds to this natural human posture.

The Lost Resting Position

What we now consider an exercise was once a normal resting position. Babies naturally squat with ease, and people of all ages in many cultures around the world use this position daily. It's not about age or special abilities—it's about regular practice. Laura points out, "They do it all the time and perhaps we should too." Being able to get into a deep squat is an indicator of total body mobility.

Why We Struggle With Squatting

Modern living has dramatically reduced our need to get low to the ground. "Once upon a time we'd have crouched down to light a fire, prepare our meals or investigate an edible plant growing on the ground. Now we have most things that we need at a convenient height," Laura notes. Our chair-dependent lifestyle has created what fitness expert Kelly Starrett calls "an imbalance between the environment and organism"—the way we live doesn't match what our bodies are designed to do.

Benefits Beyond Flexibility

The deep squat offers more than just improved mobility. "This concertina effect, even though our body is folded over, it kind of untangles the body by unlocking the ankles, hips and back," Laura explains. Regular practice can help with total body alignment, potentially reducing lower back pain and other issues. The position creates a full-body stretching and strengthening effect that counters the tightness from sedentary living.

Making the Squat Accessible

Not everyone can immediately drop into a perfect deep squat—and that's perfectly okay. "Practicing this doesn't require you to be miserable; it can be enjoyable," Laura reassures. She suggests several modifications: placing something under your heels, using the wall for support, or even sitting on a low block. The goal isn't perfection but spending time in a version of the position that works for your body.

Laura's Personal Journey

Even fitness professionals struggle with this fundamental movement. "Believe me when I say six or seven years ago I could not get into a deep squat let alone stay here," Laura admits. Her ankles were tight, her shins would burn, and her hips and lower back would scream in protest. The position felt completely unnatural to her at first, defying the idea that it could ever be restful. Yet with consistent practice, her body adapted.

The "Use It or Lose It" Principle

Our bodies adapt to the demands we place on them—or don't place on them. "If we don't use our bodies and joints to their full range of motion what happens? They tighten up, use it or lose it," Laura emphasizes. By regularly practicing the deep squat, we signal to our body that this range of motion is important, helping to maintain or restore natural mobility that many people lose over time.

Beyond Static Holding

The deep squat isn't just about getting down and staying down. "The thing about doing this is it isn't just about getting down here and staying down here but having the ability to get up from this position too which requires leg strength," Laura explains. This functional movement builds both mobility and strength, supporting everyday movements and potentially reducing injury risk as we age.

Making It Part of Daily Life

You don't need to set aside special time for deep squat practice. "Do a bit of weeding in your garden in this position, do some playtime with your children or grandchildren in this position, watch some TV in this position," Laura suggests. Even short periods throughout the day add up. The key is consistency, not duration—even 10 seconds at a time can help restore this natural movement pattern.

The Routine That Worked for Laura

Consistent practice yields results, even if progress seems impossible at first. "The routine that really helped me get better at my deep squat over the years is the Ido Portal squat routine," Laura shares. She incorporated a shortened version into her warm-up routine for years, not realizing how much she had improved until suddenly the position felt comfortable. The transformation happened gradually through consistent practice over nine years.

A Test of Mental Resilience

The squat test challenges your mind as much as your body. "I can't say it's particularly comfortable; my hips feel really tight, my lower back is stretched, and my shins are burning a little bit," Laura admits at the nine-minute mark of her demonstration. Yet she persists, showing that mental fortitude is part of the process. The test builds not just physical capacity but also the ability to sit with discomfort.

Start Where You Are

Everyone's squat journey begins at a different place. Laura encourages readers to try the test regardless of their current ability level. "If you're trying this then I'd love to know how you're doing and how it feels," she says, inviting community participation. Whether you can hold the position for 10 seconds or 10 minutes, the key is starting the process of reclaiming this fundamental movement pattern.

Our team of licensed nutritionists and dietitians strives to be objective, unbiased, and honest.

We are committed to bringing you researched, expert-driven content to help you make more informed decisions around food, health, and wellness. We know how important making choices about your overall health is, and we strive to provide you with the best information possible.

The bad news? There is no such thing as a fountain of youth. The good? There are foods you can eat to improve longevity. “Our skin reflects our overall health, and diet plays a massive role. The combination of the antioxidant effect manifests in improving the cell barrier, increased collagen production, and the enhancement of the natural oils in the skin, reflected in vibrant, youthful, and luminous skin and a reduction of fine lines and wrinkles. When skin is unhealthy, these are much more visible,” explainsMelanie Abeyta, Aesthetic Nurse Practitioner, Longevity Coach, and Owner of Harmony Aesthetics Center. She recommends focusing on an anti-inflammatory-based diet with lots of fresh fruit, water, and probiotics, which can help balance your gut, affecting your skin. “Incorporating these foods into your diet should be easy, and a variety of at least four of these foods, if not more, should be eaten daily,” she says.

Almond Milk

Almond milk is an excellent source of vitamin E, a known antioxidant. “Antioxidants protect cells from damage caused by free radicals which can often cause irreversible damage to the skin because it contributes to collagen and elastin depletion,” says Abeyta. Collagen and elastin are essential substances that give the skin elasticity and firmness. “The collagen and elastin supply of the skin is depleted after prolonged exposure to free radicals. As you age, your body cannot replenish the depleted supply; this is the primary cause of wrinkles, fine lines, and other skin blemishes. Vitamin E, present in almond milk, protects the skin from the harmful effects of free radicals and this makes the skin healthy and younger-looking.”

Avocado

“Avocado is great because it contains Vitamins C and E and essential fatty acids that decrease inflammation and redness and improve fine lines and wrinkles. It also contains antioxidants that are important to prevent UV damage and help shed dead skin cells on the skin's surface,” she continues.

Blueberries

Blueberries are high in Vitamins A and C, which have a high antioxidant content to help protect the skin from sun damage. “Vitamin A is a precursor to retinol and has a strong antioxidant and anti-aging effect,” says Abeyta.

Carrots

Carrots are not only good for your eyes but are also excellent for smooth skin, says Abeyta. “Carotenoids, found in carrots, are your protection from everyday pollutants and will prevent wrinkles. The beta carotene in carrots is a skin-friendly nutrient converted to vitamin A inside the body and can protect your skin from the sun’s harmful rays. It also helps repair skin tissues while protecting the skin from harmful radiation,” she explains.

Coconut

“Coconut is not only highly nutritious and rich in fiber, vitamins, and minerals, but it also helps support the natural chemical balance of the skin to help prevent wrinkles and functions as a protective antioxidant,” says Abeyta. “It's also great for hydrating both skin and hair and helps prevent dehydration when taken by mouth, as it contains loads of electrolytes. Coconut also helps control dandruff.”

Cucumber

Cucumber is a natural anti-inflammatory vegetable that can calm and soothe skin. “Plus, it is loaded with antioxidants and nutrients such as vitamin C and folic acid, which help reduce swelling and puffiness,” she adds. “Vitamin C helps stimulate new cell growth, and folic acid helps fight environmental toxins that can make your skin look tired or age prematurely. When combined, these help your skin look firmer and healthier. Cucumber can also help reduce breakouts as it can help cleanse the skin and tighten pores.”

Green Tea

Green Tea is high in antioxidants, such as Vitamin C, and has anti-aging benefits that help fight free radicals to protect your skin from environmental stressors that can damage and age it. “It also contains Vitamin A, which is known to help improve the skin’s texture, and Vitamin B, which helps reduce redness. Plus, it has soothing properties and will help brighten the skin,” Abeyta explains.

Nuts

Nuts such as walnuts and almonds not only help strengthen the skin cell barrier but also the natural oil barrier of the skin, which ultimately helps prevent sun damage. “Because they contain antioxidants, vitamins, and healthy fats, they will help reduce the appearance of fine lines and wrinkles and skin pigmentation while improving the overall appearance of the skin,” she explains.

Olive Oil

Olive oil contains four major antioxidants, which allow it to work as a cleanser and moisturizer. “Among these antioxidants are Vitamins A and E. Vitamin E has anti-aging benefits because it helps restore skin elasticity, reducing wrinkles,” Abeyta maintains.

Pumpkin

Pumpkin is loaded with beta-carotene, a powerful antioxidant. “This converts to Vitamin A which helps prevent wrinkles and keep your skin youthful and moisturized. This is the perfect food if you are experiencing dry skin. Pumpkin is also loaded with Vitamin C, another antioxidant that protects collagen and boosts our immune systems,” says the expert.

Spinach

Spinach is high in Vitamin C, which is essential for collagen production, and Vitamin A, which is vital for combatting inflammation and promoting cell turnover, which is essential for anti-aging. “Spinach is also rich in beta-carotene, which allows proper moisture retention in the skin to help fight wrinkles while removing dead skin cells for healthier, brighter skin,” Abeyta maintains.

Sweet Potatoes

“Sweet potatoes contain 200% of the recommended daily value of Vitamin A, which helps promote the growth of new skin cells and increases the rate at which this happens, leaving you with vibrant skin,” says Abeyta. Also, from one sweet potato, you’ll get three grams of fiber, which keeps your digestive tract healthy. “A functioning digestive tract can help keep breakouts to a minimum.”

Tomatoes

Tomatoes are rich in vitamins A, B, C, K, alpha and beta-carotene, lutein, and lycopene. “Lycopene is especially beneficial because it’s a carotenoid with a powerful anti-cancer effect. These are all great antioxidants that help the skin maintain healthy collagen and reduce the risk of skin damage,” she claims.

Turmeric

“Turmeric has brightening and anti-inflammatory properties, which help with melasma and inflamed acne. It will also help soothe and even out the skin, boost collagen production, and help with hyperpigmentation. Because it contains curcumin, a potent antioxidant, it will help neutralize free radicals that damage skin cells and contribute to aging,” Abeyta tells us.
