10 Warning Signs Your Calories Are Dangerously Low

Discover if your diet is secretly sabotaging your fitness goals.

Mario_Tomic24

Have you been struggling with constant hunger, low energy, and disappointing results despite religiously counting calories? You're not alone. A recent survey revealed that 28% of people trying to lose body fat consume dangerously low calories – between 1,500-1,700 daily – potentially sabotaging their long-term success.


Mario Tomic, a fitness coach with over a decade of experience helping thousands transform their bodies, shares critical warning signs that your calorie intake might be too low. With more than 400,000 YouTube subscribers benefiting from his science-based approach, Mario reveals how to spot and fix the common pitfalls of excessive calorie restriction. Read on to discover if you're unknowingly undermining your progress and learn how to adjust your diet for sustainable results.

Your Strength Is Declining

"If you're consistently getting worse training performance and you're not even that lean, you have a problem," Mario warns in his post. He explains that strength loss typically starts subtly – fewer reps than usual, then eventually reducing weights on main lifts.

"Poor training performance is how people end up losing lean muscle, becoming more skinny fat, and slowing down their metabolism," Mario cautions. According to him, beginners and intermediate lifters should maintain or even gain strength until reaching 10-15% body fat.

You're Losing Weight Too Fast

Mario emphasizes that rapid weight loss often backfires: "If you're above 20% body fat, aim to lose 1% of your body weight per week." For someone at 200 pounds, that's a maximum of two pounds weekly.

For those at or below 20% body fat, the target changes: "My recommendation is to lose between half a percent to about three-quarters of a percent of your body weight per week." This measured approach helps preserve muscle mass while ensuring sustainable fat loss.

You Can't Stop Binge Eating

"Most people tend to blame a lack of discipline, but the reality is the plan itself is set up for you to fail," Mario points out. He describes the typical cycle: 4-5 days of severe restriction followed by weekend binges, resulting in minimal progress despite constant struggle.

You're Below Your Minimum Calorie Threshold

"It's often mentioned that the lowest calorie intake you should have is 10 calories per pound of your target body weight," Mario explains. A target weight of 180 pounds means never dropping below 1,800 calories daily.

He says that this isn't a starting point: "This might be an endpoint for the last few weeks of a cut if you're getting super shredded, but generally, the rule stands as a soft limit where if you get under these levels, you're probably doing something that's unsustainable."

Your Hunger Is Uncontrollable

While some hunger during fat loss is normal, Mario explains the difference: "If you eat whole, healthy, unprocessed foods, get your protein, get your vegetables, drink enough water, sleep well, you'll be able to manage it well."

However, he warns, "The problem is when your calories are so low that you're hungry all the time and consistently obsessing about food." When meals never satisfy you, it's time to reassess your intake.

You Can't Focus at Work

"Getting lean is very important, but it should not come at the expense of your career, your family, and your life in general," Mario emphasizes. Constant fatigue, difficulty concentrating, and irritability are clear signs your calories are too low.

You're Not Tracking Accurately

"Most people cannot accurately estimate their calorie intake," Mario notes. He highlights common pitfalls: "We got labels that are a little bit off, and we also got eating out, which can be off as well." This inaccuracy often leads to unintentional severe restriction.

You're Experiencing Physical Symptoms

Mario points out that dizziness, headaches, and sleep problems are serious red flags. When these symptoms appear, he advises: "I would highly recommend that you increase your calories by 10% and then recalibrate from there."

You're Stuck in the Quick-Fix Mindset

"Instead of trying to fix a decade of bad eating habits in two, three months of crash dieting, take a more long-term patient approach," Mario advises. The goal isn't just reaching a target weight – it's creating sustainable habits.

You're Not Moving Enough

Mario shares a crucial strategy for maintaining higher calories while losing fat: "I highly recommend that you start walking 7,000 to 10,000 steps per day, which will help you create that calorie deficit without having to starve yourself."

For those experiencing multiple warning signs, Mario suggests "doing a diet break to maintain calories for two to four weeks to let some of that diet fatigue dissipate." Remember, sustainable fat loss isn't about reaching your goal weight as quickly as possible – it's about building healthy habits that last a lifetime. Instead of cutting calories to the absolute minimum, focus on maintaining the highest possible intake that allows for steady, consistent progress.

If you feel like your metabolism isn’t working efficiently, you aren’t alone. Kelsey Kunik, RD, is a nutritionist who tries to help people “overcome overeating without dieting.” In a recent Instagram video, she discusses metabolism and how yours could be damaged because of dieting. “Do you ever feel like other people are ‘blessed’ and you’re ‘cursed’ when it comes to your metabolism??” she writes in the beginning of the post, going on to explain why and what you can do about it. Body Network also consulted with our Resident RDN, The Diet Diva, Tara Collingwood, MS, RDN, CSSD, LD/N, ACSM-CPT, a Board Certified Sports Dietitian, co-author of the Flat Belly Cookbook for Dummies, to offer her input on the topic.


Some People Try Dieting to Speed Up Their Metabolism, But It Has the Opposite Effect

In the video, Kunik explains that oftentimes when someone believes their metabolism is damaged, they might go to the wrong extremes. “That might lead you to dieting to lose weight or speed things up, but the truth is that dieting, especially dieting on and off over several years, can have a massive impact on how efficiently you burn calories,” she says.

Here Are the Signs and Symptoms Yours Needs Help

Kelsey_Kunik_graciouslynourished1graciouslynourished/Instagram

“While this is NOT medical advice and it’s not the ONLY possible cause of these symptoms, your metabolism could use a little help if you experience any of these,” she says.

Holding Onto Extra Weight

Are you feeling heavier than usual? The first sign is “holding on to extra weight,” says Kelsey.

Fatigue

The second sign your metabolism is damaged? “Feeling tired,” she says.

Constipation

Are you having trouble going to the bathroom? “Number three on the list is constipation,” she says.

Always Feeling Cold

Are you getting the chills more than usual? The fourth sign your metabolism is damaged is that you are “always feeling cold.”

Hormone Imbalances

Are you feeling all over the place or unusually hormonal, even when it’s not that time of the month. Number five, “hormone imbalances,” she says.

The Answer: Feed Your Body with Nutrients

What should you do about it? “And the answer to repairing your metabolism is NOT another diet,” she continues. “When your body is given nourishing food on a regular basis that’s balanced with high protein, fiber, quality carbohydrates, healthy fats, and plenty of fruits and veggies, it begins to trust that food is available and your metabolism can start to HEAL itself. Your metabolism will NOT improve when your body is in a constant flux of starvation and excess — as if you needed another reason to stop dieting!”

Why Your Metabolism Could Be “Tanking,” According to Collingwood

Collingwood agrees on all points. “All of these could be signs that your metabolism is tanking,” she says, offering reasons why it may be happening. “It could be from lack of physical activity, poor diet, eating too little, getting too little sleep, or a variety of other reasons,” she says. “When under stress, the body tries to hang on to what it has which means lowering metabolism to prevent weight loss and cause fatigue and other symptoms.”

Ever feel like you're doing everything right with your diet, but your body isn't responding anymore? You're not alone. While counting calories seems straightforward, your body might be secretly fighting against your weight loss efforts. Thomas DeLauer, a nutrition coach for professional athletes with over 3.68 million YouTube subscribers, reveals the critical warning signs that your body has stopped burning fat effectively. Learn how to identify these signals and, more importantly, how to fix them.


Persistent Cold Sensitivity

If you're constantly reaching for extra layers, your diet might be the culprit. "If you restrict your calories right now, I don't think you'll start feeling cold tomorrow or the next day or even next week, but over a period of time, weeks, months, years, you might certainly start noticing a reduction in your body temperature," DeLauer warns in his post. Research from the Journal of Aging confirms significantly lower body temperatures in people following caloric restriction.

Thyroid Function Changes

DeLauer points to compelling research from the Journal of Endocrinology and Metabolism about thyroid impact. "I don't want to scare you and make you think that if you restrict calories, you're going to plummet your T3 levels. First of all, your T3 levels will come back. The thyroid is very resilient," he explains. However, long-term caloric restriction can lead to decreased T3 hormone levels, affecting your metabolism.

Strength Starts Declining

"I'm not talking about just general fatigue," DeLauer clarifies. "That can definitely happen with caloric restriction, but I'm talking more about actually feeling like you have less strength." He cites research showing a concerning 12.4% reduction in strength during weight loss. The good news? This can be mitigated by maintaining adequate protein intake during caloric restriction.

Sleep Quality Deteriorates

"If you start noticing that your sleep is going to garbage, this is a very good indicator that you're eating too little, and this can happen very fast," DeLauer warns. "This can be something that can happen as quickly as two or three days into extreme caloric restriction." Research involving 4,400 people revealed that consuming less than 16% of calories from protein led to worse sleep quality and difficulty falling asleep.

Energy Levels Plummet

"When you first restrict calories, you feel really good, you're reducing inflammation, you get more energy, you actually feel more alive and more energetic, and that lasts for a couple of months sometimes," DeLauer explains. "But then unfortunately, what ends up happening after that is that you end up in a situation where your body has to go into preservation mode."

Your Body Enters Power-Save Mode

DeLauer uses a brilliant analogy: "It's like when your iPhone gets below 20% and it goes to the yellow battery bar and it kind of downregulates the performance to preserve battery life. That's kind of what happens with your body." This power-saving mode affects everything from your workouts to your daily activities.

Mood Changes Become Noticeable

"It's almost like you have a more cynical outlook on life," DeLauer notes. "This isn't like short-term hanger. This is more long-term mood disorders that end up happening as a result of being in caloric restriction mode." The Journal of Health Psychology confirms this connection between dietary restriction and increased irritability.

Anxiety Levels Rise

"Our ability to withstand and our resilience to be able to deal with caloric restriction goes down as we age," DeLauer explains. He references a 2022 study showing how caloric restriction can increase anxiety, particularly in older individuals. This effect becomes more pronounced with age, making proper nutrition even more crucial.

Exercise Performance Suffers

"You are making this problem even worse because if you're not eating enough protein at baseline and then you're adding exercise on top of it, you're definitely not getting enough protein," DeLauer emphasizes. This creates a harmful cycle where inadequate nutrition compromises both performance and recovery.

Recovery Time Increases

DeLauer stresses that recovery becomes compromised when calories are too low. He explains that increased protein demands from exercise, combined with insufficient caloric intake, can significantly impair your body's ability to repair and rebuild after workouts.

Stress Hormones Spike

"You have increases in adrenaline, in cortisol, in epinephrine, and that will definitely impact your sleep," DeLauer notes. These hormonal changes don't just affect sleep – they can impact everything from mood to fat storage, especially in older adults who are more sensitive to hormonal fluctuations.

Metabolic Flexibility Diminishes

The solution isn't to abandon your weight loss goals, but to approach them strategically. DeLauer advises, "Don't go back to eating in a surplus and don't go back to eating how much you were eating at your heavier weight. Just slightly increase your calories and try to maintain your weight for two to three weeks, and then go back into caloric restriction, and you'll find that that really recharges you quite well."

You might be excited that you are losing weight, but are you really losing the right kind? Autumn Bates (@autumbates) is a Clinical Nutritionist with a Master's in Nutrition Human Performance. She is also a social media influencer with hundreds of thousands of followers, known for revealing tips on healthy eating, weight loss, and intermittent fasting. In a recent social media post, Autumn revealed “the seven clear signs that you're probably burning muscle and not body fat.”


It’s Important to Lose Body Fat, Not Muscle Mass

“When looking to achieve a weight loss goal, we should always be focused on losing body fat while not losing any or very little muscle mass. When we lose muscle, it results in a slower metabolism and becoming more carb-sensitive, making it a lot easier to regain the weight that we just lost. Not to mention, it just makes us less metabolically healthy,” Autumn says in the video.

There Are 7 “Clear Signs”

“It's super important you know the signs of when you're actually losing muscle so that you can shift gears and make changes asap. So I'm going to share these seven clear signs that you're losing muscle and not fat,” Autumn continues.

Sign 1: You Are Gaining Body Fat

The first sign is that you're gaining body fat. “Now, it is actually possible to lose weight while still gaining body fat so that the scale could be going down, but you could actually be gaining body fat. That's why it's really important actually to measure the right thing,” Autumn says. “I never recommend just using the scale.”

Use the Right Measurements, Like InBody

“You want to use measurements that actually track body fat as well as muscle mass. My favorite option is the InBody. It actually breaks down body fat and muscle mass in pounds as well as percentages. So you can actually see where that weight loss or weight gain is coming from because if you're gaining weight, but if it's all from muscle, that's actually a good thing,” Autumn says.

If You Are Losing Muscle While Gaining Fat, Your Metabolism Is Slowing Down

“The body's going to be stronger. You're going to have a healthier metabolism, and overall, you're actually making progress toward body recomposition. But if you're losing muscle while gaining body fat is actually making it so the metabolism is slower, you're in a less healthy metabolic state, and you're much more likely to gain back the weight that you lost,” Autumn points out.

You Can Also Use a Tape Measure

“You could also use a tape measure, which is a better form of measurement than just a typical scale,” she says. “The InBody can often be found at a gym, or sometimes you can find at a local health food store.”

Sign 2: You Are Losing Muscle Mass

“The second is that you're losing muscle mass,” Autumn continues. “This is what happens when you simply just eat less without actually paying attention to the right types of foods to help hold onto muscle mass. So if you're using the typical eat less, move, more strategy of just calorie restriction and doing a lot of cardio or just a lot of movement in general, this is the common outcome.”

This Happens When You Drop Your Calories, and You Don’t Exercise

“Let's say you're focused on just counting calories, reducing calories, and you drop down to 1600 calories. You start to lose weight on the scale, and so you think you're making progress, but then suddenly, you hit a plateau. So you think, okay, I need just to eat a little bit less. So you drop your calories by another 200. You break through that plateau, and you start to lose weight again, just on the scale. Then you plateau again, and you can see how this process repeats itself. So, in order to continue seeing results, you have to keep eating less and less and less, but if you're actually keeping track of the right measurements, you would see that that weight loss was coming from muscle and not body fat, or at least largely from muscle, which is why you had to keep eating less and less and less in order to achieve or maintain those results,” Autumn says.

Muscle Mass Prevents This From Happening

When we have more muscle mass, it actually gives us a lot more flexibility with the types of foods we can be eating to help support our goals or even maintain our goals, and it helps to prevent this issue of having to eat less and less and less in order to achieve those goals.

Sign 3: You’re Feeling Exhausted After Working Out

The third sign is that you're feeling exhausted after a workout. “This is actually a big sign of overtraining, and one of the results of overtraining is actually losing muscle mass,” Autumn says.

This Happens From Overtraining

“Good high-quality training that's well structured should make you feel more energized for the day and not totally wiped out. When you're in a state of overtraining, it's really common to either go into the workout feeling burnout or to come out of the workout feeling burnout, whichever it is. You shouldn't be feeling excessively burnt out after the workout,” Autumn says.

A Lot of People Don’t Know They Are Overtraining

“What's tricky about this one is a lot of people don't think they fall into this category because maybe they're not working out every single day, and so they assume that there's no way they could be overtraining. But a lot of people actually fall into this trap of overtraining because they don't consider the other stressors in their life over training results because we don't have enough time to recover from stressors. Typically, we would just think of the stressor coming from exercise, but it can come from other stressors as well. Like for example, if you stand a lot at work, that is a big stressor on the body, or if you're eating a really poor diet, that is also a stressor on the body, or if you have just a lot of mental or emotional stress, again, another stressor on the body,” says Autumn.

Make Sure to Give Your Body Rest and Repair

“So if you're not getting adequate rest and repair from your workouts while also accounting for the other stressors in your body, whether it be physical or mental, this can also lead to a state of overtraining. And the horrible irony of it is that from the state of overtraining, you start to see the reverse of what you're actually trying to achieve. You start to see muscle being lost as well as body fat increasing. So a lot of people try to overcorrect the wrong direction and add in more workouts, which is actually just making the problem worse,” Autumn says.

Sign 4: You Are Feeling Weaker

The fourth sign is that you're feeling weaker. “This really goes along with the overtraining. If you find that with your workouts you can no longer do the same intensity or you're not progressing with your workouts, but instead maybe you're actually regressing, then you're probably losing muscle mass,” Autumn says.

“So if maybe in the past you're able to use 15-pound dumbbells, but now you can only use like 12 or 10-pound dumbbells, and that is a huge red flag, you should be getting progressively stronger when you're actually maintaining or even increasing muscle mass a bit and not getting weaker,” she explains.

Sign 5: You Aren’t Sleeping Well

“The fifth is you're getting poor sleep, and specifically, you're getting poor sleep all of a sudden. Like if you've always had poor sleep, there could be other issues going on, like you don't have a good bedtime routine or maybe some nutrient deficiencies,” Autumn says.

If You Aren’t Eating Enough, You Could Be Having Cortisol Spikes and That Can Disrupt Sleep Hormones

“But if suddenly, especially if you are on some type of body recomposition journey, you're noticing that you're not getting great sleep or you're waking up throughout the night, this is also another huge red flag because when you're not eating enough to help support body recomposition and therefore could be losing muscle mass, this can result in cortisol spikes throughout the day,” Autumn says. “That can disrupt our sleep hormone melatonin, which makes it much more likely that you're going to have either restless sleep or wake up often throughout the night. If, instead, you're getting deep, high-quality sleep every single night, then this is a good sign that you probably are on the right track.”

Sign 6: You Are Feeling Cold All the Time

The sixth sign is that you're feeling cold all the time, “especially again, if this is a sudden change,” Autumn says. “When we aren't eating enough to support our body's needs during body recomposition, this can lead to the body having difficulties with regulating internal temperatures, plus having muscle mass actually helps to keep us warm. It's a big portion of actually regulating our body temperature. So if you're losing muscle mass, it's getting harder for the body to actually maintain a consistent body temperature and therefore could result in you feeling colder more often, especially when other people aren't feeling very cold.”

Sign 7: You Are Losing Motivation

“The seventh clear sign is that you're just losing motivation in general or you have low energy levels. We need proper fuel and a well-functioning metabolism in order to have good energy levels and feel good throughout the day,” Autumn says.

A Slowing Metabolism Results in Lower Energy Levels

“On the flip side, a slowing metabolism as a result of losing muscle mass can result in lower energy levels or feeling sluggish or unmotivated again, especially if this is a sudden change. If usually you're somebody who's highly energized, highly motivated, and suddenly you're just feeling really sluggish and not feeling motivated for work or your workouts or things that usually you would be motivated for, then this is a very big red flag that you need to take note of,” Autumn concludes.

When working out and dieting, the goal is to burn fat – not muscle. But how do you know if you are actually accomplishing it? In a new YouTube video, Autumn Bates, a Clinical Nutritionist who has a Master's in Nutrition Human Performance reveals the “five signs that you're burning fat and not muscle during your weight loss journey.”


1. You Can’t Rely on a Traditional Scale

“If you're purely relying just on a traditional scale, it's pretty much impossible to actually tell if you're losing body fat or if you're losing muscle mass. And this really matters if you're looking for long-term sustainable results,” Autumn explains.

2. Losing Fat – Not Muscle – Is Beneficial in the Long Run

“Most traditional calorie restricted protocols will result in a significant amount of muscle loss. This muscle loss can then cause a decrease in metabolism as well as a host of other issues for long-term health, like reduced bone density, increased risk of osteoporosis, as well as increased risk of insulin resistance and type two diabetes,” she says, adding “losing muscle mass just makes us more sensitive to carbohydrates, so it makes gaining weight back so much easier.” She explains that using a few tools can help address this issue, allowing you to keep your metabolism revving and so you can reap the “benefits of having muscle mass on our body for long-term health and make it so we can maintain our results for the long run.”

3. First Sign: Your Clothes Are Fitting Differently

The first sign that you're losing body fat and not muscle mass” is that “your clothes are fitting differently,” Autumn says. “Now, you've probably heard the saying that muscle weighs more than fat, and although that's like a little play on words, what it really means is that per volume muscle is going to be a lot more dense. So five pounds of muscle is going to look a lot smaller than five pounds of fat. That's why you'll often see these photos on Instagram or other platforms where you see these people who look really toned, really fit, but they weigh more than you would've expected. That's because they have lower body fat, but they have a lot higher muscle mass. So when you're losing body fat while maintaining or even slightly increasing muscle mass, it can result in your clothes feeling a lot looser. And this is because we're getting rid of body fat that takes up more physical space, but leaving behind the leaner muscle mass, especially for women. You might notice this more so in your pants.”

4. Second Sign: You Are Not As Hungry

“The second sign is that you're not as hungry,” says Autumn. “Burning fat as fuel tends to make us less hungry, especially when you're focused on the types of foods that help us to more efficiently burn fat as fuel, which are those that are rich in protein, fat, and fiber,” she adds, emphasizing that “protein is the most important macronutrient when it comes to actually maintaining muscle mass during a weight loss process. It's really just mandatory to be eating enough protein to actually maintain muscle mass. When you're losing weight and eating enough protein for the body's needs is so satiating, you're just not really hungry. So eating high quality proteins like eggs, Greek yogurt, beef, chicken, pork, tempeh, are great tools for not only helping to keep muscle mass while burning body fat, but also to just not feel hungry during the weight loss process.”

5. Third Sign: Your Measurements Are Decreasing

The third sign that you're burning fat and not muscle “is that the measurements are decreasing even if the scale is not,” says Autumn. “I prefer taking measurements rather than just looking at the scale because it actually gives you an idea of what your body composition is, depending on which form of measurement you're using. It can even tell you specifically how many pounds of body fat you lost or how many pounds of muscle mass you lost or gained. A regular scale can't do that.” You can also measure yourself using an old school tape measure.

6. Fourth Sign: You Are Getting Stronger

“The fourth sign is that you're getting stronger,” she continues. “Assuming that you're actually exercising and using some type of resistance training, which is a necessity to maintain muscle mass during the weight loss process, you should be feeling stronger during your weight loss journey. If you're progressively feeling weaker after every week of workouts, then you're very likely losing muscle mass. If that's the case, it's definitely time to reassess your protein intake, especially to make sure it's actually fitting your body's needs and to make sure that you're getting that protein from high quality complete sources. So if you need a little refresher on that, you can check out my video right up here for the 10 best high quality sources of protein.”

7. Fifth Sign: You See Muscle Definition

The fifth sign? “You start to notice muscle definition,” says Autumn. “Maybe you start to notice that your quad muscles are peaking out or that you're starting to see your abs a little bit. If that's the case, all of these are signs that your body's actually losing body fat, which helps you show muscle definition because muscle definition and toning is really only going to start to become obvious as we decrease body fat percentage, although you can definitely be losing body fat and not noticing muscle mass quite yet. But if you do start to notice muscle definition, then that is one way to determine that you're actually burning body fat.”

8. Take Periodic Progress Pictures

Autumn recommends “taking periodic progress pictures” which “can be helpful for actually seeing this progress,” she says. “I did this for myself as well, because it's hard to notice those changes day after day, but actually seeing pictures of your progress can really help to see those changes”

9. An Expert Agrees That the Scale Is Not a Good Measure of Health

Chris McMahon, a nutrition and fitness coach, agrees that you can’t rely on the scale when you are trying to get into shape. “Even if you're working out, you'll see the scale go up and things of that nature because you're retaining water and glycogen, which is an energy form that we can keep in our muscles,” he says.

10. He Also Agrees That Fiber and Protein Intake Are Crucial

He also agrees that your nutrition goals should be eating “plenty of fiber,” as it is “connected to hunger and fullness” and amping up your protein intake. “For most individuals who are trying to lean out, we want to make sure that your protein intake is high, because that will help with hunger and fullness,” says McMahon. “It'll also help with preserving the muscle mass you have. And if you are lifting weights and you are training, it'll help you build muscle and recover. So we want to make sure that's higher.”

💪🔥Body Booster: Try not to rely on the numbers on the scale when you are losing weight. Losing fat – not muscle – is an important goal when it comes to weight loss. Improving muscle mass will help you achieve long term weight loss goals.

Are you trying to lose weight and blast fat over 40? Julie Clouse is a social media influencer and fitness and macros expert who tries to “inspire others to be the best version of themselves.” In a new social media post she unveils her healthy habits for losing weight post-40. “Top 10 non-negotiables for fat loss after 40,” she writes. “It won’t always be easy, but it can be simple. Habits build momentum. 90% of people who love exercising & eating healthy didn’t start that way. But by staying consistent, they felt better, looked better, and fell in love with the process,” she writes.

Create a Calorie Deficit

The first thing to do is make sure you aren’t consuming more than you are burning. “Create a calorie deficit (at least 250 cals)” she writes.

Amp Up Protein Intake

Next, amp up your protein intake. “Eat 25-30g of protein at every meal,” she says. According to clinical trials, consuming more protein than the recommended dietary allowance not only reduces body weight (BW), but also enhances body composition by decreasing fat mass while preserving fat-free mass (FFM) in both low-calorie and standard-calorie diets.

Track Food

Next, make sure you are keeping track of everything you eat. “Track your food for overall calories and protein,” she says.

Lift Weights

Strength training is another core habit. “Lift weights 3-4 times per week,” she writes. According to the Mayo Clinic, strength and weight training help reduce body fat, preserve and increase lean muscle mass, and burn calories more efficiently. Strength training may also help you:

  • Develop strong bones
  • Manage your weight
  • Enhance your quality of life
  • Manage chronic conditions
  • Sharpen your thinking skills

Walk Up to 10,000 Steps Per Day

Next, get your steps in. “Get 8-10k steps per day—add a weighted vest for an extra burn!” she suggests. A 2018 study published in the journal Obesity found a link between walking 10,000 steps a day and weight loss and weight management. Other studies published by the Journal of American Medical Association (JAMA) in JAMA Neurology and in JAMA Internal Medicine also linked walking 10,000 steps a day to less dementia and less cardiovascular disease overall, with less heart disease, less heart failure, and fewer strokes.

Eat Whole Foods

When it comes to diet, it’s not just about the numbers but the quality of food you eat. “Choose 90% Whole Foods,” she says.

Hydate

Make sure to stay hydrated. “Drink half your body weight (lbs) in ounces of water—I always add electrolytes too,” she writes. According to the Mayo Clinic, hydration is essential for various reasons. Water helps eliminate waste through urination, perspiration, and bowel movements, keeps your temperature regular, lubricates and cushions joints, and helps protect sensitive tissues.

Don’t Cut Out Entire Food Groups

You don’t need to be super restrictive. “STOP cutting out entire food groups. Instead of saying no sugar, allow yourself a small treat that fits your goals. No food is off-limits,” she says.

Limit Alcohol

Don’t drink your calories. “Limit alcohol—this one is HUGE!” she maintains. Not only is alcohol high in calories but the more you drink, they more likely you are to make poor food choices and neglect exercise.

Don’t Give Up

Finally, be patient. “STOP throwing in the towel after one bad day. Just get back on track the next day,” she reminds. “This is a lifestyle, NOT a diet. A few ‘bad’ days won’t ruin your progress. Ditch the dieting mentality and six-week plans—that was my BIGGEST mistake for years. Stay consistent, make it sustainable, and fit in the foods you love. It CAN work. You CAN be fit long after 40!” And if you enjoyed this article, take advantage of these 15 Quick Ways to Lose Body Fat Percentage in a Week.
