10 Fasting Mistakes This Weight Loss Expert Says You Need to Stop Making Now

Are you struggling to see results with intermittent fasting? You're not alone. Many people start their fasting journey with high hopes, only to hit frustrating plateaus. The good news? Most fasting setbacks come down to a few simple, fixable mistakes. Dr. Morgan Nolte, a board-certified clinical specialist in geriatric physical therapy and founder of Zivli, has identified the most common pitfalls that derail fasting success. With her expertise in metabolic health and weight management, she helps clients overcome these obstacles to achieve lasting results. Read on to discover how to avoid these common pitfalls and finally unlock the weight loss results you've been working toward.

What Is Intermittent Fasting?

Unlike traditional diets that focus on what to eat, intermittent fasting centers on when you eat. As Johns Hopkins neuroscientistMark Mattson explains, "Our bodies have evolved to be able to go without food for many hours, or even several days or longer." This natural fasting ability stems from our prehistoric ancestors, who often went long periods between successful hunts.

How Does It Work?

"After hours without food, the body exhausts its sugar stores and starts burning fat," says Mattson, who has studied intermittent fasting for 25 years. He calls this "metabolic switching." This differs from typical American eating patterns, where frequent meals prevent burning fat. "If someone is eating three meals a day, plus snacks, and they're not exercising, then every time they eat, they're running on those calories and not burning their fat stores."

You're Overeating Processed Foods During Your Eating Window

"Even keto or low-carb processed foods can halt your progress," warns Dr. Nolte in her post. She emphasizes that while intermittent fasting is powerful, what you eat matters just as much as when you eat. The golden rule remains: focus on real, unprocessed foods to optimize both weight loss and metabolic health.

You're Fasting Too Long Too Soon

Shocking your body with dramatic fasting windows can backfire. Dr. Nolte recommends gradually increasing your fasting period by 30-60 minutes rather than jumping straight to lengthy fasts. "Starting too aggressively often leads to a restriction mindset and eventual overeating," she explains.

You're Not Drinking Enough Water

Many forget that we get significant hydration from food. "When fasting, you need to be extra mindful about water intake," says Dr. Nolte. She recommends drinking half your body weight in ounces daily, aiming for clear or light yellow urine as an indicator of good hydration.

You're Consuming Sweet Drinks While Fasting

Even zero-calorie sweeteners can trigger insulin release. "Anything sweet, including alcohol and diet drinks, signals your brain that calories are coming," Dr. Nolte explains. This can increase hunger and disrupt fat burning, defeating the purpose of your fast.

You're Skipping Electrolytes

Dr. Nolte admits this was her own mistake for years. "Unflavored electrolytes during fasting can improve muscle recovery and overall energy," she shares. She recommends either using plain LMNT supplements or making your own mixture with magnesium, potassium, and sea salt.

You're Afraid to Exercise While Fasting

Exercise during fasting can be highly effective when done right. Dr. Nolte recommends Zone 2 aerobic exercise at about 70% of your maximal heart rate. "This level of activity is perfect for fat burning while maintaining muscle mass," she notes.

You're Eating Too Many Starches and Sugars

"There are essential proteins and fats, but no essential starches or sugars," Dr. Nolte points out. To maximize fasting benefits, she advises reducing starchy and sugary foods even during eating windows, as these trigger the largest insulin responses.

You're Fasting at the Wrong Time in Your Cycle

For menstruating women, timing matters. Dr. Nolte recommends focusing fasting efforts during days 1-14 of your cycle. "The week of your period through ovulation is optimal for fasting," she explains, while suggesting more flexibility around ovulation and pre-menstrual phases.

You're Fasting Despite Poor Sleep

Sleep deprivation increases hunger hormones, making fasting much harder. "If you're not getting at least seven hours of sleep, focus on improving that before extending your fasts beyond 14 hours," Dr. Nolte advises.

You're Being Impatient About Results

"There is no entitlement in weight loss," Dr. Nolte emphasizes. Initial weight loss might be water weight as insulin levels drop, and that's normal. She encourages focusing on long-term health benefits rather than quick fixes, noting that sustainable results take time.

The Benefits of Intermittent Fasting

The science behind fasting is compelling. "Many things happen during intermittent fasting that can protect organs against chronic diseases like type 2 diabetes, heart disease, age-related neurodegenerative disorders, even inflammatory bowel disease and many cancers," Mattson notes in his research published in the New England Journal of Medicine. Studies have shown improvements in memory, heart health, physical performance, and blood sugar control.

Safety and Considerations

While intermittent fasting can be practiced safely by many people, it's not suitable for everyone. Mattson advises that "it can take two to four weeks before the body becomes accustomed to intermittent fasting." He notes that while initial hunger and irritability are common, many people stick with it after the adjustment period because they notice improved well-being. However, certain groups should avoid fasting, including children, pregnant women, people with type 1 diabetes, and those with a history of eating disorders.

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

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

"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."

Have you tried every diet out there but still can't seem to keep the weight off? You're stuck in a cycle of restrictive eating, temporary results, and inevitable rebound. But according to one expert, the problem isn't your willpower—it's your blood sugar.

Jessie Inchauspé, known to her followers as the Glucose Goddess, is a biochemist who's challenging everything we think we know about weight loss. With over 1.3 million YouTube subscribers and a New York Times bestselling book, she's revealing why traditional dieting advice might be making your weight loss journey harder than it needs to be. Read on to discover the science-backed approach that could finally help you break free from the dieting cycle.

The Weight Loss Industry's Billion-Dollar Mistake

The multi-billion dollar diet industry has built its fortune on quick fixes and restrictive eating plans. "When I wrote my first book in 2022, even though my focus was never to help people lose weight, my publishers wanted me to put weight loss or lose weight on the cover because they know that it sells," Jessie reveals in her video podcast. But this obsession with quick results is exactly what's keeping people trapped in the weight loss cycle.

The Hidden Reason You Can't Stop Eating

What if your food cravings weren't about lack of willpower? "When we are on a glucose rollercoaster, after every glucose spike, there is a glucose dip, and this dip activates the craving center in our brain that tells us to go find some cookies, some chocolates, some chips," Jessie explains. This insight reveals why traditional diets often fail—they don't address the underlying blood sugar issues driving your hunger.

Why Your Body Fights Against Weight Loss

The real problem goes deeper than calories. "The reason that fat burning is important is not because it's going to make you lose weight. It's because if you're able to burn fat for fuel, it means that you are metabolically flexible," Jessie emphasizes. Without this flexibility, your body remains stuck in a cycle of constant hunger and energy crashes.

The Truth About Constant Hunger

If you're always hungry, there's a scientific reason: "People who are not very metabolically flexible, who rely mostly on glucose for fuel all the time, they're hungry every two hours. They get what's called low blood sugar. And if their meals are delayed or if they don't have a snack with them in their car, they can get really shaky and nauseous," Jessie explains. This constant need for food isn't normal—it's a sign your body isn't working efficiently.

The Three Keys to Natural Weight Loss

When you focus on blood sugar stability, three powerful changes occur: "The reduction in cravings, the reduction in hunger, and the increase in burning fat for fuel," says Jessie. These changes create the perfect environment for natural, sustainable weight loss.

Why Quick-Fix Diets Make Everything Worse

"I think if your main focus is losing weight at all costs as quickly as possible, that often leads to very habits that are not sustainable, and that can actually be worse for your health and cause damage," Jessie warns. "Do not succumb to any of the crazy diets promising you fast, 10-pound in two-day weight loss. That's not what we're here for."

The Simple Changes That Transform Your Body

Instead of strict rules, Jessie advocates for easy, sustainable habits: "The hacks that I share are sustainable, easy partners that you take along with your days and your weeks and your months and your years and do whenever you can," she explains. "They don't ask you to count any calories. They don't ask you to cut out any food groups. They just teach you about what molecules are in your food and when, how, and what combination to eat your food."

How to Break Free from Food Guilt

The beauty of this approach is its flexibility. "I like to say that they're a little bit like drink water and brush your teeth. If you can't do them one day, one week, one month, it's not a big deal," Jessie shares. "The point is not you do everything right or you're not doing it at all. It's purely take the principles with you and do them when it is easy."

The Science-Backed Results

The proof lies in the research. In a study of 2,700 people following Jessie's method for just four weeks, "90% of participants were less hungry, 89% reduced their cravings, 77% had more energy," she reports. Most importantly, 38% of those wanting to lose weight succeeded—without following a restrictive diet.

Your Path to Sustainable Weight Loss

The most profound changes go beyond the scale. "What they had been after for a very long time was not necessarily weight loss, it was actually just to feel good in their body, to have a clear brain, to be happy to wake up in the morning with energy, to not feel so addicted to sugar all the time," Jessie reveals. By understanding and stabilizing your blood sugar, you can finally achieve the sustainable weight loss that has eluded you—without the struggle of traditional dieting.
