12 Mistakes to Avoid When You Want to Lose 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

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."

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

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.

Weight loss is not easy—but for the most part, it’s straightforward. “Healthy weight isn’t about following a diet or program,” says the CDC. “Instead, it involves a lifestyle with healthy eating patterns, regular physical activity, and stress management. People with gradual, steady weight loss (about 1 to 2 pounds per week) are more likely to keep the weight off than people who lose weight quickly.” Here are major mistakes to avoid if you want to lose weight and, just as importantly, keep it off.

Too Stressed

Chronic stress leads to inflammation, which impedes weight loss efforts. “The link between stress and weight gain is real,” says the Cleveland Clinic. “Those elevated cortisol levels circulating in your body lower your metabolism and encourage cravings for fat and sugars.”

Sedentary Lifestyle

Sitting too long can lead to weight gain and a slower metabolism, studies show. “It is thought excessive sitting slows the metabolism – which affects our ability to regulate blood sugar and blood pressure, and metabolize fat,” says the NHS. “And may cause weaker muscles and bones.”

Too Much Sugar

Too much sugar is terrible for your health—and your waistline. “I don’t think we have enough evidence yet to suggest that sugar is the reason for the obesity epidemic,” cardiologist Chiadi E. Ndumele, MD, MHS, tells Johns Hopkins Health. “But there is enough evidence to say that elevated sugar consumption is an important contributor to weight gain.”

Lack of Sleep

Not getting enough sleep impacts weight loss in many ways. "Working to find ways to clean up sleep hygiene may help people to extend sleep time to the recommended seven to nine hours per night," Beth Frates, MD, tells Harvard Health. "This could, in turn, lead to consuming fewer calories and even weight loss in people who are in the overweight category by BMI."

Avoiding Weights

Shutterstock

Don’t avoid weights if you want to lose weight! "Strength training helps you lose weight and keep it off by building muscle tissue," according to Beaumont Health. "The more muscle mass you have, the higher your metabolic rate tends to be. More muscle also helps your body burn more fat than muscle, which is important if you want to lose weight and keep your strength."

Not Enough Protein

Your body needs protein to build muscle. Protein is also important for satiety. “Protein plus fiber keeps us full longer, which means you don’t feel the urge to eat as often,” chef and dietitian Nancy Waldeck tells Piedmont Healthcare. “This helps keep weight down while fueling our cells with the right nutrients they need.”

Too Many Calories

Shutterstock

It can be useful to track calories to make sure you’re in a deficit. “Losing weight essentially comes down to one thing: By burning more calories than you’re eating, a math solution called a calorie deficit,” says the Cleveland Clinic. “You can create a calorie deficit by reducing your calorie intake or combining fewer calories with more exercise.”

Get Your Heart Rate Up

Shutterstock

Cardio—even gentle cardio like walking and hiking—is great for fat loss. “Cardio’s role in helping you shed pounds is burning calories. The more you exercise, the more calories you’ll burn,” according to Beaumont Health. “If you’re trying to lose weight, you should aim for doing cardio at least five days per week for a total of at least 250 minutes (4 hours, 10 minutes) each week.”

Drink More Water

Drinking water helps weight loss in many ways. For example, drinking water before a meal can help prevent overeating. "Water is critical in every cellular activity of our body from head to toe," registered dietitian nutritionist Elizabeth Huggins tells Johns Hopkins. "Staying hydrated helps the body run more efficiently and helps us feel better."

Not Food Prepping

Shutterstock

Prepping your food ahead of time eliminates decision-making about what you will eat. "With anything in life, if you fail to plan, you plan to fail. That applies to meal planning as well," registered dietitian Silvia Veri tells Beaumont Health. "Planning meals and snacks ahead of time increases the chance for success, it increases the likelihood a healthier food choice will be made."

Set Realistic, Sustainable Goals

Shutterstock

Trying to lose an unrealistic amount of weight in too short a time may undermine your efforts. “Depending on your weight, 5% of your current weight may be a realistic goal, at least for an initial goal,” according to the Mayo Clinic.

“If you weigh 180 pounds (82 kilograms), that's 9 pounds (4 kilograms). Even this level of weight loss can help lower your risk of chronic health problems, such as heart disease and type 2 diabetes.”

Not Having Support

Don’t be afraid to ask for help or support from others. It will help you stay accountable and motivated. “Ideally, find people who will listen to your concerns and feelings, spend time exercising with you or creating healthy menus, and share the priority you've placed on developing a healthier lifestyle,” says the Mayo Clinic. “Your support group can also offer accountability, which can be a strong motivation for sticking to your weight-loss goals.”
