Top 6 Fat Loss Mistakes Women Over 40 Need to Stop Doing Now, Experts Say

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

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

"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

"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

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

"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

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

"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."

Feeling frustrated with your fitness routine? You're not alone. While you might be doing everything "right," certain morning habits could be working against your body's changing hormonal landscape after 40—and a leading hormone expert has noticed a pattern.

Angela Garcia has spent 25 years watching women make the same well-intentioned mistakes. As a Registered Dietitian Nutritionist and Board-Certified Specialist in Obesity at Thrivelab, she's helped countless women navigate the complex relationship between hormones, exercise, and weight management. From her practice in San Antonio, she's identified key morning habits that are holding women back.

Here's what she wants you to stop doing—and what to do instead.

The Morning Timing That's Working Against You

Your first few hours set the tone for your entire day—especially during menopause. "Morning habits directly impact energy levels, hormonal balance, and metabolic health," Garcia explains. During this time, fluctuations in estrogen, testosterone, and cortisol affect everything from your metabolism to bone density and muscle mass.

Why Your Old Exercise Rules Don't Work Anymore

If you've noticed stubborn weight gain around your middle, hormones might be the culprit. "As estrogen and testosterone levels decrease, metabolism slows down, leading to increased fat storage, especially around the middle," Garcia notes. She adds that these changes also affect how your body recovers from exercise, making traditional workout approaches less effective.

The Hidden Damage You're Doing

The changes run deeper than just weight gain. "These hormonal changes can affect muscle mass, bone density, and insulin sensitivity, making it harder to maintain a healthy weight and overall metabolic function," Garcia explains. She points out that stress compounds these issues: "Elevated cortisol levels from stress can exacerbate these issues, contributing to fatigue and slower recovery."

Morning Mistakes That Sabotage Your Progress

Garcia identifies several common morning routine errors that can derail your progress. Skipping strength training is a major pitfall, as is overdoing cardio sessions. "Long or intense cardio sessions can elevate cortisol levels, which worsens fatigue and encourages fat storage," she warns. Other mistakes include neglecting recovery time, poor hydration, and rushing through breakfast.

The New Morning Rules You Need

The solution starts with smarter exercise choices. "Light weightlifting or resistance band exercises can build muscle and boost metabolism," Garcia advises. She recommends starting your day with proper hydration and a balanced breakfast containing protein, healthy fats, and fiber. Short bursts of high-intensity interval training can be more effective than lengthy cardio sessions.

Why You Need More Recovery Than You Think

Don't underestimate the importance of rest. "Failing to incorporate rest or low-intensity activities like stretching or Pilates can increase stress on the body and hinder recovery," Garcia cautions. She emphasizes that recovery isn't just about physical rest—it's about managing overall stress levels. "Activities like yoga or mindfulness exercises help reduce cortisol levels and support hormonal balance."

The Exercise Approach That Works With Your New Hormones

Adapting your workout to your body's new needs is crucial. Garcia suggests focusing on "shorter, lower-impact strength and cardio sessions in the morning." This might include resistance bands, bodyweight exercises, or light weights. She emphasizes the importance of listening to your body and adjusting intensity based on your energy levels and symptoms.

The Simple Morning Habit You're Overlooking

Many women overlook this simple but crucial factor. "Not drinking enough water in the morning can worsen symptoms like fatigue, poor focus, and hot flashes," Garcia points out. She recommends making hydration a priority first thing in the morning to help with energy levels and body temperature regulation.

The Right Way to Time Your First Meal

When you eat matters as much as what you eat. "Eating a balanced meal shortly after waking helps stabilize blood sugar levels and supports metabolic function throughout the day," Garcia explains. For women dealing with night sweats or hot flashes, she recommends opting for lighter, cooler breakfast options and maintaining consistent meal timing to support hormonal balance. "Having a lighter, cooler breakfast and spacing meals to prevent prolonged fasting can improve energy and temperature regulation."

Are you struggling with fat loss? Coach Melissa, founder of Fit Mission Nutrition, specializes in helping women over 35 “lose a pant size in 6 weeks.” In a recent Instagram video, she shares the most common things you might be doing wrong that are keeping you from losing weight. “If you’re eating ‘healthy’ but your body won’t seem to drop the fat you want, these are the most common mistakes I see,” she writes, launching into the seven biggest fat loss mistakes that people make.

Eating Too Much

Eating too much is the first mistake. “This one seems obvious, but it’s what I see most looking at new clients' food logs. Foods you think are healthy, you can still overeat, like mindless snacking on pecans, which can really add calories. Also, things like sauces & dressing are most underestimated. I’ve seen a 1000-calorie salad on a client’s log,” she writes in her post.

Drinking Calories

Next is drinking your calories. “Your morning latte, energy drinks, alcohol & even ‘healthy’ meal replacement shakes are on this list. Most are high in sugars & extra calories. Also, the very act of chewing & digesting solid food burns more calories than drinking & helps your brain register that you have taken in calories, so you don’t want more soon after,” she says.

Not Eating Enough Protein

Not eating enough protein is another major mistake. “Protein over all else makes you feel full at meals, digesting it actually burns calories, it increases your metabolism & leads to overall decreased calorie consumption,” she writes.

Not Managing Stress

Another common mistake? Melissa reveals that she is not managing stress. ”Constant stress makes your body produce a hormone, cortisol. This hormone increases the storage of body fat if it’s not controlled,” she says.

Lack of Sleep and Rest

Lack of sleep and rest can be keeping you from burning fat, she claims. “Just like above, lack of sleep & rest raise cortisol levels & cause insulin sensitivity to decrease. This means that your body is more likely to store fat & not get the recovery it needs to burn fat,” Melissa says.

Lack of Water

Are you hydrating enough? Lack of water could be making you hold onto fat. “Your body requires water for all of its metabolic processes & functions. Lack of water slows metabolism, hinders its ability to get rid of waste, and you will think you are hungry when really…you’re thirsty,” she writes.

Too Much Cardio

You might think that all the cardio you are doing is helping you burn fat. However, according to Melissa, it could be the opposite. “Daily high-intensity cardio causes overproduction of cortisol, inflammation & fatigue. Which goes back to the not enough rest/recovery above!” she writes.
