6 Metabolism Mistakes Making Women Over 40 Gain Weight

If you're struggling with unexplained weight gain, afternoon energy crashes, and frustrating food cravings, your morning routine might be the culprit. But don't worry – making a few simple changes can help you reclaim your energy and metabolism.

Angela Garcia, Registered Dietitian Nutritionist and Board-Certified Specialist in Obesity at Thrivelab, has spent over 25 years helping patients optimize their nutrition and hormone health. Now based in San Antonio, Texas, she specializes in helping women navigate the complex relationship between nutrition and hormones, particularly during perimenopause and menopause. Read on to discover six-morning mistakes you need to fix – and what to do instead.

How Hormones Hijack Your Morning Metabolism

"During perimenopause and menopause, hormonal changes slow our metabolism, reducing our total calorie needs," explains Angela. "We may have sleep disturbances, fatigue, and carb cravings driving us towards sugary and fatty foods for quick energy. Alterations to our gut microbiome during this time will also impact our metabolism by changing the way we absorb nutrients, process energy, and regulate our blood sugars."

According to the National Institutes of Health, "Consistent meal timing aligns with the body's circadian rhythms, potentially reducing the risk of obesity and improving metabolic health." This makes your morning routine particularly crucial for metabolic health.

Mistake: Skipping Your Morning Meal

"Good morning habits are crucial for setting up our day successfully in terms of meeting our nutritional needs for protein, hydration, and providing energy for the day ahead," says Angela. "I often see patients miss breakfast as they get full on their cup of coffee, so their first meal of the day may be lunch. However, this can work against the metabolism, especially if weight loss is your goal. Eating too little will cause the metabolism to slow and the body to hold on to excess weight."

Solution: Power Up with Early Protein

The Mayo Clinic reports that "consuming at least 30 grams of protein at breakfast may enhance feelings of fullness and aid in weight management." This is because "protein decreases the hunger hormone ghrelin and increases hormones like peptide YY, GLP-1, and cholecystokinin, which promote feelings of fullness and satisfaction."

Mistake: Playing Nutrition Catch-Up All Day

"One of the most common morning routine mistakes is missing breakfast and not getting adequate hydration!" Angela warns. "This usually means you must catch up at some point later in the day, and for many people, this means snacking after dinner. A protein-rich breakfast with complex carbohydrates gives you more control over your appetite throughout the day and prevents an afternoon energy slump which can worsen symptoms of irritability and mood swings."

Mistake: Late-Night Snacking Habits

Research from the National Institutes of Health confirms that "eating during inactive periods, such as late at night, can disrupt the body's internal clock, leading to weight gain and metabolic issues."

Mistake: Loading Up on Morning Carbs

Angela explains the science behind morning carb cravings: "Hormone-related weight gain is generally driven by insulin resistance. This is where the insulin produced by our pancreas becomes less effective at lowering blood sugars. Insulin resistance is responsible for belly fat, carb cravings, brain fog and fatigue. We tend to be more insulin-resistant first thing in the morning. So, you don't want to add to this with a starch-heavy breakfast like cereal and toast. This is an ideal time to fuel up with protein and 1-2 servings of complex carbohydrates (fruit and wholegrains) instead."

Solution: Balance Your Breakfast Plate

The Mayo Clinic recommends "a balanced diet for weight loss typically includes 40-50% carbohydrates, 25-35% fat, and 20-30% protein." Harvard Health adds that "high-fiber foods like fruits, vegetables, whole grains, and legumes can help control hunger and prevent overeating."

Mistake: High-Impact Morning Workouts

"High-impact exercise can work against our hormones during pre and post-menopause if there is some adrenal dysfunction," Angela cautions. "Our adrenal glands are responsible for producing hormones such as cortisol and DHEA that are essential for maintaining our internal equilibrium. However, with unrelenting life stressors, elevated levels of cortisol and declining levels of DHEA are observed. This shows up as anxiety attacks, mood swings, and depression. High-impact exercise will stress our system further, so opting for lower-impact exercise such as walking and/or strength training in the morning is the most beneficial."

Solution: Time Your Meals Right

Timing is crucial for metabolic health, as Angela explains: "It is best to eat breakfast within the first couple of hours of waking for the most benefit in terms of energy and metabolism. If you plan to exercise, then refuel within one hour of finishing, when your muscles are most receptive. If you wish to practice fasting, then consider time-restricted feeding. This is a feeding pattern based around circadian rhythms and usually involves an eating window between 6 am and 6 pm for the most benefit. Research is ongoing, but participants in one study reported improved sleep and increased alertness during the day."

Solution: Plan Your Way to Success

Shutterstock

The National Institute of Diabetes and Digestive and Kidney Diseases notes that "proper meal spacing can influence metabolism and energy expenditure, potentially aiding in weight management." Additionally, the Mayo Clinic finds that "meal planning is associated with better dietary quality, variety, and adherence to nutritional guidelines, contributing to weight loss success."

Solution: Make Hydration a Priority

WebMD underlines that "staying hydrated is important for weight loss. Drinking 8-10 cups of water daily not only supports metabolism but can also help reduce hunger by promoting a feeling of fullness. This is especially important if you're increasing your protein intake, as hydration helps with protein metabolism."

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

Shutterstock

"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 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

Shutterstock

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

Shutterstock

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

Shutterstock

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.

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.
