This Guru Doctor Reveals 8 Hormone Mistakes Making You Gain Weight After 40

Are you fighting an unexplained weight gain after 40? You're not alone. According to renowned women's health expertDr. Mindy Pelz, speaking with Marie Forleo (#1 New York Timesbestselling author of Everything is Figureoutable), many women are making critical hormone mistakes that sabotage their metabolism. "Women as a whole, we are massively dysregulated right now. Our metabolic system is dysregulated. Our nervous system is dysregulated. Our hormones are dysregulated," explains Dr. Pelz.

"When my patients say, 'I went to sleep, and I woke up, and I felt like I was 20 pounds heavier,' I believe them. Because it can be a fairly rapid change if they're not doing something about it," says Dr. Monica Christmas, menopause program director at the University of Chicago Medicine.

Here are the biggest hormone mistakes women over 40 are making and how to fix them.

Mistake 1: Still Counting Calories After 40

"We're done with calories. It tells us nothing about our health. It doesn't give us any vision of good hormonal health. It is an old, outdated theory that needs to go away," Dr. Pelz says in the video. Instead of counting calories, she emphasizes blood sugar management: "Blood sugar absolutely tells you how quickly you're going to age, if you're going to store fat, if you're going to balance hormones."

Mistake 2: Not Adapting Your Diet to Age-Related Changes

"When people come to me and say, 'I've always eaten this way, and I've never gained weight,' I say to them that it doesn't matter what you always did. That doesn't fly anymore," says Dr. Christmas. She emphasizes that after 40, you must be "meticulous about what you put into your body and be diligent about the way you move your body."

Mistake 3: Ignoring Hidden Obesogens in Your Food

"All fat is excess. It's not undisciplined. It's not you're a bad person, it's not your genetics," explains Dr. Pelz. She reveals a shocking truth about food chemicals: "There are chemicals that are put in our food that are literally known obesogens... it tells your stem cell... to make fat cells." Your body stores these toxins in fat cells to protect vital organs.

Mistake 4: Misunderstanding Female Hormones After 40

"Men are run by one hormone, testosterone. Women are run by three hormones – estrogen, progesterone, and testosterone. And we work off a 30-day cycle," explains Dr. Pelz. "Our three hormones all want a different lifestyle. They all react to toxins differently. They just are a little more sophisticated." This complexity increases after 40, when hormone levels begin to fluctuate more dramatically.

Mistake 5: Relying on Hormone Therapy Alone

Dr. Christmas warns that hormone therapy isn't a weight-loss solution: "Hormone therapy (HT) will not help you lose weight, nor is it indicated for weight loss. It may actually contribute to a little bloating in the midsection for some patients."

Mistake 6: Fasting Incorrectly After 40

"Mistake number one is they fast too long... what ends up happening is all of a sudden we got a bunch of complaints like people's hair, they're losing their hair. Or if you fast too much, you actually metabolically can get stuck and your body starts to hold on to weight," warns Dr. Pelz. She emphasizes that women should never fast the week before their period, explaining that "progesterone is like, 'girl, give me a cookie, give me some chocolate. Sit your ass down, and then I'll give you a menstrual cycle.'"

Mistake 7: Eating at the Wrong Times

"When melatonin goes high, you actually become more insulin resistant," explains Dr. Pelz. This means eating late at night can lead to increased fat storage, especially after 40. She recommends waiting an hour after waking before eating breakfast, as "cortisol was meant to make you move" and can affect insulin sensitivity in the morning.

Mistake 8: Following an Unbalanced Exercise Routine

"You can't exercise your way out of a bad diet and you can't eat your way out of no exercise. It's got to be a combination of both. Especially in midlife and beyond," emphasizes Dr. Christmas. She recommends 150 minutes of moderate-intensity physical activity and two days of muscle strengthening per week for women over 40.

The solution combines several key strategies:

1. Choose nature's carbs: "A good carb is one that the earth provided us, and a bad carb is most likely one that humans made for us," Dr. Pelz explains.
2. Feed your gut microbiome: "There are bacteria, good bacteria in your gut that sends your brain signals that says, 'feed me,'" says Dr. Pelz.
3. Follow a Mediterranean diet: Dr. Christmas recommends this approach as it "has been shown to lower the risk of cardiovascular disease, metabolic syndrome, osteoporosis, dementia and certain cancers."
4. Support natural detox: "When we're shedding every month, we're actually detoxing," Dr. Pelz reveals, noting the importance of maintaining healthy cycles as long as possible.

Do you want to lose weight and look younger? Dr. Fay Kazzi is a registered dietician with an extensive background in nutrition and dietetics who has a PhD in rehabilitation science. “From the age of 35 and on, when it comes to stubborn weight, the usual weight loss fixes like caloric deficit and exercise might not be as helpful as they used to be, which is why I'm here to help you guys out,” she says at the start of the clip. As part of her “Age Gracefully Nutrition” series, she goes on to explain why you need to change your approach to weight loss as you get older and reveals her top three “weight loss hacks.”

Weight Management Gets Challenging As You Age

“You have that one friend that always seemed to have been on the heavier side, and then some time goes by, you don't see them for a while, and then you see them again. But something has changed. They've lost a significant amount of weight like we're talking about 15 or 20 pounds, and then the first thing that you notice is, wow, they look so much younger. So yes, weight loss not only improves your metabolic health, but it also makes you appear younger, healthier, and more vibrant,” she says in the post. “Why does weight management get a bit more challenging after 35? Here are three possible reasons,” she says.

You Experience Metabolic Decline at 35

“Number one, natural metabolic decline around the age of 35,” she reveals. “A woman's metabolic rate tends to slow down due to natural changes in muscle mass and hormonal shifts. The lean muscle mass, which burns more calories than fat tissue, naturally declines with age. A 2021 study in the Journal of Science found that the metabolic rate slows down approximately one to 2 percent per decade after the age of 30, meaning fewer calories are burned at rest than when you're younger. So you could basically just sit around and do nothing, and your body would burn calories when you were a teenager and in your twenties. This gradual reduction makes it easier to gain weight and harder to lose it without adjusting caloric intake and increasing our physical activity, which is another reason why building muscle is so important in your late thirties.”

You Also Experience Hormonal Changes

“Number two reason, hormonal changes, and insulin sensitivity,” she continues. “Hormonal fluctuations, especially around perimenopause, which can start as early as your late thirties, can significantly impact your weight loss. So estrogen, which influences where the body fat is stored, starts to decline, often resulting in more abdominal fat storage. I know it's the worst, and as we all know, it's harder to lose. So additionally, a decline in estrogen can contribute to reduced insulin sensitivity, which can lead to higher blood sugar levels and then increased fat storage. Research in the Journal of Clinical Endocrinology and Metabolism highlights that even slight changes in estrogen levels can increase body fat, particularly, unfortunately, again in the abdominal area.”

And, Lifestyle Demands and Stress Levels Usually Increase

“Number three reason is lifestyle demands and stress levels,” she continues. “Women in their late thirties often juggle careers and family responsibilities and other social demands, which can lead to increased stress and disrupted sleep patterns. So, both stress and lack of sleep can raise your cortisol levels, a hormone that's associated with increased appetite and fat storage. Again, it goes to the abdominal area. A 2018 study in the Journal of Obesity found that higher cortisol levels were linked to weight gain, especially in midlife women, due to the stress of balancing various life demands. So this can make weight loss especially harder despite the diet restrictions and exercise efforts.”

However, There Are Things You Can Do to Mitigate the Effects

However, there are things you can do. “Even though these factors combined can make weight loss after 35 more challenging with targeted strategies, it is possible to mitigate these effects. There are ways, and there are paths. There are three things you can start doing today to lose weight and keep it off,” she says.

First, Increase Your Protein Intake

“Number one, increase your intake of protein per meal,” she suggests. “This is such a game changer. If you're a woman and you're in your late thirties, you absolutely have to start building all of your meals around protein, not carbohydrates. Depending on your activity level, you need about 0.8 to 1.2 grams of protein per kilogram of weight. So if you're, say, 125 pounds, that's about 57 kilograms, so roughly about 45 to 50 grams of protein, you want to split that throughout the day. So about 20 to 25 grams of protein per meal, and this is totally doable.” She points out that one cup of Greek yogurt is 20 grams, half a cup of ground turkey is about 20 grams, half a cup of tofu is about 20 grams, and one cup of lentils is about 20 grams. “The reason increasing protein helps is because it boosts the metabolism. It preserves lean muscle mass, and it makes you feel full, reducing your appetite. So how does that work? Protein increases the production of satiety hormones, glucagon-like peptide one cholecystokinin, while reducing, reducing the production of hunger hormones such as ghrelin.”

Second, Narrow Your Eating Window

“Number two, narrow your eating window,” she suggests. “By now, for sure, you've probably heard a lot about intermittent fasting, time-restricted eating, and chrononutrition. Let me distill it for you. We really don't need to have three large meals spread throughout the day. Narrowing your eating window gives your body the ability to rest, rejuvenate itself, and set all of its metabolic ducks in order, so to speak. When you don't eat for a longer period of time, your body runs out of sugar and starts to burn fat for energy. This process is called metabolic switching. If you don't have any other underlying medical conditions, the general rule of thumb is to eat your day's calories within an eight-hour window, so have a late breakfast, let's say around 11:00 AM, and try to have your last meal before 6:00 PM. Also, when you stop eating earlier in the day, this is going to improve your sleep, which is also going to increase your metabolic health.”

Third, Increase Intake of High Quality Fat

Number three, increase your intake of high-quality fat. “I know this sounds so counterintuitive, but there's so much evidence right now that high-quality organic fats like cold pressed olive oil, grass-fed butter, raw nuts and seeds, the fat in free-range eggs, the fat and avocados, coconut cream, and kinds of milk are extremely satiating and nutrient dense and actually do not contribute to obesity,” she says. “It's been well established in research for decades now that one of the outcomes for epileptic patients who are put on a strict high fat, low carb diet as part of their treatment plan to manage their epileptic episodes is that these patients also lose weight by significantly reducing the carbohydrates. The body switches to burning fat for energy, which can result in weight loss, especially with that stubborn fat, but let's not get carried away. The recommendation for a generally healthy woman is to reduce the carbohydrates and increase the high-quality fats moderately.”

However, do not confuse this with overly processed, poor-quality fats like seed oils and their hydrogenated byproducts. “These include canola oil, corn oil, safflower oil, vegetable oil, soybean oil, and margarine, which are all in most processed foods such as your pastries, your chips, and your canned soups. Yes, they are hiding in your canned soups, crackers, cookies, breakfast cereals, mixed nuts, and even some of the bread brands out there. These kinds of fats do the opposite. They have no nutritive value, and they're loaded with empty calories. They actually contribute to inflammation, which increases the retention of fat,” she says.

“These are three recommendations that you can start applying today to see a dramatic and sustained difference in your weight loss journey in just a few weeks. Of course, practices like regular exercise, decreasing your intake of, let's say, sugary beverages, and decreasing your stress levels will also assist with healthy and maintained weight loss,” she concludes.

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.

Are you trying to lose weight in your 40s, but your best tactics simply aren’t working? Ashley Waldorf, RN, is a Hormone Health and Fat Loss Coach who has been practicing as a nurse for over 20 years. In a new social media post, she reveals some of the mistakes she made that kept her burning fat. She eventually identified them and went on to lose 15 pounds after 40. ”Navigating weight loss after 40 can be challenging, with many myths and misconceptions that complicate your journey,” she writes in the post. “Here are seven mistakes you might be making that are keeping you stuck.”

You Stick to a Plant-Based Diet

The first mistake? You think that a plant-based diet will help you lose weight. “While plants and fiber are essential, we actually need more protein as we age due to the anabolic resistance. Aim for 1 gram of protein per pound of ideal body weight,” she suggests in her post.

You Are Doing Juice Cleanses

Juice cleanses were all the rage, but thinking they were effective is a big mistake, per Ashley. “Our liver requires essential amino acids to effectively detoxify because they help break down and remove toxins,” she says. “Juices deprive your body of essential nutrients & you are generally losing water weight.”

You Think You Can Fast Your Way to Slim

Think you must fast your way slim? Nope, says Ashley. “While time-restricted eating can be a good tool for weight loss, it does not work for everyone. A 12-hour fast is plenty, especially when you have hormonal imbalances and trying to heal,” she says.

You Need to Be in a Severe Caloric Deficit to Lose Weight

You must be in a severe caloric deficit to lose weight,” is “an outdated model,” says Ashley. “The quality of your food is more important than the quantity. A balance of protein, healthy fats, and working up 25-35 grams of fiber can help lower insulin levels and improve fat burning.”

Doing Cardio Over Weight Lifting

“More cardio is better for fat loss” is also antiquated, says Ashley. “Cardio is also a tool but weight lifting is much more important for your metabolism and longevity. Aim for 3 days of resistance training per week at minimum,” she says.

Avoiding Carbs

“Carbohydrates are bad” is simply not true. “As women, we actually do much better & feel much better when we are consuming quality carbohydrates- fruit, veggies, sweet potatoes and rice,” she says.

Believing That Hormones Don’t Matter

If you believe that hormones don’t matter, you are making a mistake. “Our hormones are a key component to fat loss. We have thyroid hormones, metabolic, reproductive, and stress hormones. I have found a holistic trio that helps balance all of these. They have resulted in a 15-pound weight loss, reduced anxiety, better sleep, more energy, and so much more!” she says.
