20 Intermittent Fasting Mistakes Preventing You From Losing Weight

Struggling with stubborn belly fat that just won't budge, especially after 40? Functional medicine dietitianMay Tom, RD understands your frustration. "This is a particular pain point that drives a lot of my clients to finally come and work with me," says May. Through her practice, she's helped countless clients break free from the cycle of stubborn belly fat using science-based strategies rather than extreme dieting. Keep reading to discover the most common belly fat mistakes you might be making – and learn exactly how to fix them.

Mistake 1: Not Understanding How Belly Fat Works

"Belly fat, also known as visceral adipose tissue, has a unique relationship with insulin resistance," May explains in her post. She describes it as a vicious cycle: "When you're insulin resistant, you put on more weight around your organs. When you have more weight around your organs, they send out signals called adipokines that cause you to become more insulin resistant."

The Cleveland Clinic adds that "visceral fat surrounds your organs and can put you at risk for conditions like diabetes, heart disease, polycystic ovary syndrome (PCOS) and more."

Mistake 2: Waiting Too Long to Address the Problem

"By losing 5% to 10% of your body weight, you can improve blood pressure, blood sugar, cholesterol levels, mobility, sexual function and more," states Dr. David Creel from the Cleveland Clinic. This aligns with May's observation that addressing belly fat early can prevent long-term health issues.

Mistake 3: Not Tracking Your Blood Sugar

"Diabetes is 10 years in the making, and belly fat is a sign you're on that path," May warns. She recommends using a continuous glucose monitor (CGM) for real-time feedback. "This is real data about you," she emphasizes. "It's a total eye-opener."

Mistake 4: Relying on Artificial Sweeteners

"Being diabetic doesn't mean converting everything to sugar-free, including Diet Coke," May cautions. The Cleveland Clinic supports this, noting that "we're still learning about the long-term effects of different low-calorie sweeteners on things like taste preferences, cravings, gut bacteria and insulin resistance."

Mistake 5: Avoiding Strategic Fasting

May's "Nourishing Fast" approach, based on the Fasting Mimicking Diet, has shown impressive results. "Recent research with 100 participants showed significant drops in A1C, fasting glucose, insulin resistance, visceral fat, total body fat, and BMI," she reports.

Mistake 6: Doing the Wrong Type of Exercise

Shutterstock

The Cleveland Clinic recommends "150 minutes per week of moderate-intensity cardio exercise" for best results. May adds that "one meta-analysis of 32 studies found that HIIT and moderate-intensity aerobic exercise was more beneficial to lowering visceral adipose tissue than resistance training."

Mistake 7: Focusing Only on Ab Exercises

Shutterstock

"When you do sit-ups and other core-strengthening exercises, you're strengthening muscles in the abdomen, but that doesn't specifically target the fat," May explains. The Cleveland Clinic adds that "strength training helps build muscle — or at least maintain muscle as you lose fat. And muscle burns calories."

Mistake 8: Ignoring Your Saturated Fat Intake

Shutterstock

"Certain genes predispose you to being sensitive to saturated fat where it really adds to your waistline very quickly," May explains, recommending limiting saturated fat to 10% of daily calories.

Mistake 9: Not Activating Your AMPK

Shutterstock

May describes AMPK as "something that senses fuel availability in the body, and when it doesn't sense enough fuel, it activates and helps to mobilize fat." She points to dark chocolate as a natural AMPK activator.

Mistake 10: Overlooking Temperature's Impact on Fat Loss

Shutterstock

"One study found that whole body cryotherapy for three minutes each session reduced abdominal adiposity in menopausal women," May reports.

Mistake 11: Skimping on Fiber

Shutterstock

The Cleveland Clinic emphasizes that "foods that contain a high amount of soluble fiber can slow down the passage of food from your stomach to your intestine by forming a gummy gel. That means they help you feel fuller for longer."

Mistake 12: Not Timing Your Protein Right

"It's not that you need to be on a high-protein diet as much as you should focus on getting adequate protein that's spread throughout the day," May advises. The Cleveland Clinic adds that "protein helps keep you feeling satiated, lowers hunger hormone levels and may even help you eat less at your next meal."

Mistake 13: Underestimating the Impact of Poor Sleep

Shutterstock

The Cleveland Clinic explains that "when we don't sleep well or we're sleep-deprived, it can impact hunger hormones. There's actually a biochemical response to sleep deprivation that makes us want to eat more."

Mistake 14: Neglecting Your Gut Health

Shutterstock

"When you're eating, think I'm not just eating for me, I'm eating for 10 billion," May emphasizes, referring to gut bacteria. She warns that restrictive dieting can harm your gut microbiome: "Take care of them, they're going to take care of you."

Dy Ann Parham, 57, is a Mindset Coach whose priority is “being healthy and fit” and helping others do the same. In a new video, she discusses simple ways to help women over 50 lose weight. "If you are exhausted, frustrated, and confused about what you should be doing as a 50-plus-year-old woman to help you balance out your hormones and allow your body the opportunity to lose some weight, then today's video is for you,” Parham says.

1. Confusing Messages

Youtube.com/@DyAnnParham

“Calories in, calories out, debunked. Breakfast is the most important meal of the day, debunked. The entire food pyramid has been demolished and revamped. Carbohydrates were in, and now they're out. Fat was out. Now, it's in how we consume. Protein has changed. High-intensity interval training is now out, and everybody is supposed to be doing zone two training. There is even new scientific research that has debunked the old research about hormone replacement therapy,” she says. “So why is it that we are still seeking out scientific data to make decisions on how it is we should be taking care of ourselves, especially on the most basic level of nutrition and losing weight," Parham adds.

2. She Advocates Intermittent Fasting

Shutterstock

“I have been teaching intermittent fasting as a lifestyle approach now for almost eight years,” explains Dy Ann. “I made all the same mistakes you are probably still making with intermittent fasting because of all the buzzwords that are out there. I was limiting the amount of hours I was fasting. I was putting crazy things in my fasting window because that's what all the ‘experts’ were saying to do. I was watching my calories, still like all the other things. Nothing was budging for me, my health journey, and my desire to lose weight until I just made it simple.”

3. She Does a 20-Hour “Clean” Fast

Shutterstock

She says that a “20-hour clean fast” helped her reverse her “pre-diabetic condition and to help my body lose weight and help my body lose body fat that I was unhappy with,” she claims. “I really just simplified everything that I could about my intermittent fasting practice as well as what I was doing in my nutrition,” she continues. “It is the simplest way to balance your hunger's hormones out so that you can, in fact, lose weight.”

4. A 20-Hour Fast Helps the Body Regulate Insulin

Shutterstock

Dy Ann explains that maintaining “hormonal balance” is key to losing weight. “And that is exactly what the 20-hour fast does for us. It helps us regulate insulin. It helps our body pull from storage. All of this, all of the glycogen that we have been backing up for years and putting away in storage. It helps us regulate our hunger cues, and it just gives us that energy and vitality that we are all looking for. And it is simple, and it is free,” she continues. “There is a little bit of a learning curve and a little bit of a mindset shift that we need to make in order for us to trust our body and give our body the time in the space that it needs to turn inward and feast on itself.”

5. If You Aren’t Losing Weight with Fasting, You Might Be Making Mistakes

Shutterstock

“So many women are practicing intermittent fasting and they're still like, ‘Why am I not losing weight?’” she says, explaining that there are some “very common mistakes women are making and most of the time it's just you're making it too complicated,” she says. “If you're going to fast for all of the benefits that fasting can provide for you, then the recommendation I give all women is if you're gonna fast, just fast, if you're asking questions about ‘Does this break a fast?’ or ‘Should I do this during my fasting window?’ then you're probably not approaching an intermittent fasting lifestyle from the right mindset.”

6. Fast Long, Feast Well, Train Smart

Shutterstock

“All the things that are going on with you that you are currently researching for a solution for can be found if you just simplify what it is you're doing. We call it fasting long, feasting well, training smart,” she says. “Fast long enough to get the results that you say that you want for yourself and give yourself the benefit of the doubt and just keep that fast clean.”

7. When It Comes to Feasing, Find the Foods That Work For You

Shutterstock

What does feasting mean? “Figure out the food that works for you. No complicated meal plans to follow. No exhausting grocery shopping halls that you have to do. No endless hours in the kitchen doing food prep. The feasting part is very, very simple. Find the foods that work for you,” she says.

8. Find Your “Rinse and Repeat” Meals

Shutterstock

She also recommends finding meals you like and sticking with them. “Be honest about the decision-making process regarding those foods. Meaning are they going to serve what you say you want? Are they gonna allow you the opportunity to look and feel your best? And if they are, those are your go-to foods. We call those our rinse and repeat meals,” Dy Ann says.

9. Incorporate Movement You Enjoy

Shutterstock

“Then learn how to move your body in a way that is exciting for you in a way that you look forward to. We do need to start incorporating training smart into our lifestyle, but you get to figure out what it is that works for you,” she explains. “If you're a runner, run, if you're a walker walk, if you play pickleball, play pickleball, whatever it is for you that lights your fire and gets your body moving, then girlfriend, that's what you need to be doing,” she says.

9. Keep It Simple

“Forget about all the nonsense that you're hearing on the internet and just make it simple, fast long, feast well, train smart,” she says. “You'll be absolutely amazed at how simple this lifestyle can be. And once you figure out the rhythm of fasting, long feasting well, and training a smart girlfriend, you will have nothing else that you'll need to do. You just keep showing up for you.”

Are you trying to lose weight but not finding much success? It’s possible you are making a common mistake. Juliana Crispo is a mom of 2 kids 3 and under, a Lifetime Natural Pro Bikini Champion in 2 Federations, and a former successful Silicon Valley-based tech executive and entrepreneur.
”Today, we're talking about weight loss myths. I'm someone that has made every single one of these mistakes,” she says. “These are mistakes that I made for years on my fitness journey.”

Mistake 1: Only Exercising

Shutterstock

“Mistake number one, I thought for the longest time that exercise was the key to fat loss,” she says. “What I would do is I would go to the gym, I'd get on a cardio machine, I'd screw around with some weights, and then I'd go home, and I would just eat like I normally did, but I would also overcompensate because I was hungry from all that cardio. Cardio just makes me ravenous.”

She Walks

Shutterstock

Now, she avoids intense cardio. “This is why now my main source of cardio is just walking 8,000 to 10,000 steps a day because it doesn't make me very hungry,” she explains.

Mistake 2: Not Getting Into a Calorie Deficit

“Also, when I'm just getting into a new weight loss phase, I prioritize getting my calorie deficit down first,” she says. “I'll take one, up to two weeks just to master my calorie deficit before I even touch exercise. The reality is you don't even need exercise to lose fat. Just eat in a calorie deficit.”

Also, Make Sure to Strength Train

Don’t Overlook Strength Training. Cardio activity is just a tool to make it go faster, and strength training is what gives your body shape so you don't get skinny fat.

Mistake 3: Relying on Intuitive Eating

Shutterstock

Her third mistake? “I believed intuitive eating would work for me,” she says. “Intuitive eating is a way of eating popularized by this book, and it took off in the height of diet culture because so many people have had horrible experiences with dieting.” She explains that in the boo, there are ten principles of intuitive eating, “but the general gist is to be mindful and eat when you're hungry and stop when you're full.”

Lots of Influencers Rely on Intuitive Eating

Shutterstock

“Many fitness influencers to this day talk about intuitive eating as a good approach to weight loss. For example, one of the first fitness influencers I ever followed was Buff Bunny, and she posted a video called This Diet Worked for Me. In this video, she talks about how she used intuitive eating to lose weight because you don't have to track anything.”

It’s Not Great for Fat Loss

Shutterstock

However, there is a “flip side,” she points out. And that is, many people maintain intuitive eating, which isn’t great for fat loss. “For the longest period of time, I felt like something was wrong with me because I couldn't just listen to my body. It wasn't until I started tracking and weighing my food that I really started to learn putting a meal together with enough protein, carbs, and fats really makes me feel full, and then I'm able to do other things besides focus on food for a solid three to four hours. It was great.”

Mistake 4: Fear of Tracking Calories

Shutterstock

Her next mistake? “I was afraid of tracking calories and weighing my food,” she says. For example, chicken and broccoli can help you gain weight, but if you eat too much of it, you will gain weight. You can benchmark your progress with this useful Lean Body Mass Calculator.

You Can Gain Weight From Healthy Food

“I got chubbier from eating chicken and broccoli because I felt so deprived of the foods I really loved,” she says. “While trying to eat clean with this chicken and broccoli diet, I would binge on foods I actually craved late at night.”

Portion Size Matters

Shutterstock

“However, had I invested time upfront in just learning from tracking and weighing my food, I could have learned that there's no such thing as unhealthy or bad foods,” she says. The important thing is focusing on “healthy portion sizes, and so I could still enjoy all the things I love in moderation on my weight loss journey without creating these fear foods of anything that fell outside of my chicken and broccoli meal plan,” she says.

You Won’t Have to Track and Weigh Food Forever

Shutterstock

“You don't have to track and weigh your food forever. Even a lot of fitness influencers say they'll go from periods of intuitive eating where they just listen to their body a little bit, and then when they start to get a little bit more fluffy, they'll bring it in, they'll start tracking and weighing their food. Again, it's not about being married to your food scale or MyFitnessPal. It's about learning and then unlearning along your journey.”

Mistake 5: Not Understanding Macros

Mistake 5? “I didn't understand how to allocate macros when I was in my dieting phase,” she says. “Many of you know macros are just protein, carbs, and fats. They serve different purposes to nourish your body. At the end of the day, the only thing that matters is being in a calorie deficit.”

Make Sure to Fill Up

Shutterstock

“However, the key to sustaining a calorie deficit is just don't get hungry. That's the name of the game. Don't get hungry. As soon as you get hungry, all bets are off. The little hangry monster comes out, and it's just, it's just bad.”

Pay Attention to Your Macro Breakdown

Shutterstock

“Having a general idea of the macronutrient distribution you're consuming is very important to make sure that you stay feeling full, and if you stay full, you're more likely to adhere to your calorie deficit,” she says. “A macro breakdown that works for me to keep staying full, feeling satiated, and adhering to my calorie deficit is having about 30% of my calorie deficit coming from protein, 30% coming from fat, and about 40% coming from carbohydrates.”

If You Don’t, You Could End Up Binging

“What happens if I'm not in the ballpark generally of hitting these macros over a period of a few days is on like day three, I'll start to get really hungry, and then all of a sudden I find myself like wandering into a seven 11 and just buying donuts and eating them, and I don't know what happened.”

Mistake 6: Overcompensating

The next mistake is “huge,” she says. “I would try to overcompensate when I had one of my 7-Eleven freakouts. This was mainly more so in my bikini competitor days because you had to be so black and white about your diet. What would happen is when I messed up somehow, I just like ate a donut or three, I would try and overcompensate the next day by doing more cardio or trying to eat fewer carbs and fats, and this was just a recipe for this horrible cycle of binging and over-exercising and feeling horrible, and that's just no way to live.”

Don’t Fall Into the “Binge and Restrict” Cycle

Shutterstock

“Now, if that happens and I overeat on my diet for the day, I just stick to what I would normally eat on my daily diet, almost as if that 7-Eleven incident never happened. I just learn from it, and I move on. So whatever you do, if you ever have a mess up in your diet, don't ever, ever, ever try and overcompensate by doing more cardio or eating less. Just eat as if you would normally eat so that you don't fall into any binge and restrict cycle,” she suggests.

Mistake 7: Fear of Building Muscle

Shutterstock

Her next mistake? “I was afraid of building muscle,” she says. She explains that building muscle is great because “the more mass and the more muscle that I have, the more I weigh, the more I can eat and not gain too much fat,” she says.

You Can Reshape Your Body with Exercise and Nutrition

“It took me years of focused effort in the gym and being methodical about my nutrition to put on the muscle mass I was able to achieve here. The cool thing I've learned through bodybuilding is that you can use training to emphasize certain parts of your body and de-emphasize others,” she says. “You can literally reshape your body with the right training and nutrition, and that's what I love so much about lifting weights.”

Mistake 8: Not Stacking Habits

“If I were to stack priorities when it comes to actually losing fat, it would go like this. Very foundational sleep. Get your sleep in order. Second thing, get your calorie deficit in order. Third thing, do some strength training. Focus on maintaining as much muscle mass as you have, and then maybe consider adding in some cardio,” she concludes.

Are you trying to lose weight but aren’t really getting anywhere? According to experts, you might be going about your weight loss journey the wrong way. In fact, even some of the top diet and fitness experts have made weight loss mistakes themselves. Body Network spoke to a few trainers and nutritionists and asked them about the biggest missteps they took on their fitness journeys.

1. Going Overboard with Calorie Counting

Shutterstock

While it is good to keep tabs on your food consumption, Risa Sheppard, Master Pilates trainer, creator of The Sheppard Method, advises not to go overboard. “Counting every calorie of every piece of food,” is one of the mistakes she made. “It became time consuming and frustrating.”

2. Starving Your Body of Carbs

Shutterstock

Mr. America Jason Kozma, a personal trainer in Los Angeles, reveals the biggest mistake he made while preparing for a bodybuilding competition. “I had gotten too heavy bulking up to add more muscle mass,” he explains. He spent four months dieting for a spring show “and still didn’t get in shape.” After a short break he reset his goal to a fall show and dove headlong into his diet. “I was using an extremely low carb approach as I felt I had too much fat yet to burn. What I actually did was I starved my muscles of carbohydrates for so long that at the end my body couldn’t assimilate carbohydrates and I couldn’t ‘pump u’ for the show,” he continues. “My body fat measured lower than ever for this show but I didn’t look as good as I had a year and a half prior at a higher body fat level. The net result was that I lost muscle using this approach: I was actually smaller and lighter than I was before the ‘bulk up.’” Note: He still won the show!

3. Doing Too Much Cardio

Shutterstock

Diet and fitness expert Adita Yrizarry-Lang, ISCA, NASM, ACE, AFAA, reveals that one of the biggest mistakes she made was doing too much cardio. “When I first started in fitness, this was the prescription…do a lot of cardio. The reality is that you burn more calories when you have muscle on your body, combining weights with cardio is the right way to do it,” she says.

4. Not Looking at Serving Size on Packages

Shutterstock

Yrizarry-Lang claims that another mistake is only looking at calories on a package, and not the serving size. “We were mesmerized by the lo-cal labeling on a package,” she says. “Unfortunately, we never looked at the serving size and then came to realize we were ingesting too many calories at a time.”

5. Falling Victim to Low Fat, Highly Processed Foods

Shutterstock

Just because something is low-fat doesn’t make it healthy. Yrizarry-Lang says that some people consume “too many processed carbs, because they are low fat.” While this might be okay for runners, going for 10 to 20 mile runs, “those carbs convert to fat,” for most of us.

6. Daily Weigh-Ins

Shutterstock

Weighing oneself every single day is another mistake, says Sheppard. “It can be discouraging,” she explains. “Try to weigh yourself less and pay more attention to how your clothes are fitting. Remember muscle weighs more fat so if you are on an intense exercise regime the muscle you gain will trim in less but may not show on the scale.”

7. Crash Diets

Shutterstock

If a diet seems too good to be true, it probably is. “The all-time worst” mistake people make is going on crash diets. Why? You might “lose weight at the moment” but you will “gain it back with a few extra pounds,” says Yrizarry-Lang. “This slows down the metabolism and makes it even harder to lose weight at a later date.”

8. Focusing on Exercise for Weight Loss

Shutterstock

One of the biggest mistakes people make is “thinking more exercise will cause them to lose weight,” says Sheppard. “80 percent is dieting and 20 percent is exercise,” she reminds.

9. Falling Victim to “Get Thin Fast” Scams

Shutterstock

Sheppard strongly advises against any products or diet that claim to help with rapid weight loss. “Do not succumb to quick weight loss scams or dangerous pills. Remember Rome wasn’t built in a day and neither is weight loss,” she says.

10. Comparing Yourself to Others

Remember that your fitness journey is your own and “comparing yourself to other people” will “only add to your stress and discouragement,” says Sheppard. “We are all built differently with different bone structure and hereditary genes. Love who you are inside and it will reflect on your outside.”

💪🔥Body Booster: Beware of low-fat, processed foods. Unless you run for 20 miles a day, you should probably pass on a highly processed energy bar – those carbs might convert to fat unless you are working them off.
