    S1E28 Why You Can't Lose Weight After 40 with Dr. Sherry Brewer
    2026/08/21
    In this episode of 40s Forward, Dr. Betsy Greenleaf sits down with Dr. Sherry Brewer, double board-certified physician in internal medicine and integrative medicine, certified functional medicine practitioner, founder of Body by Alchemy, and author of Why You Can't Lose Weight. Dr. Brewer knows weight-loss resistance personally. During perimenopause, while navigating divorce, exercising intensely, eating a Paleo diet, and seemingly doing everything "right," she gained about 20 pounds. That experience sent her searching beyond the traditional calories-in, calories-out model. Together, Dr. Greenleaf and Dr. Brewer explore why the strategies that worked in your 20s and 30s may stop working after 40—and how hormones, stress, sleep, muscle, blood sugar, nutrition, and the gut microbiome can influence metabolic health. What You'll Learn in This Episode • Why eating less and exercising more can backfire in midlife • How perimenopause and menopause change metabolism • Why intense exercise may raise blood sugar when the body is already stressed • How under-eating can contribute to weight-loss resistance • Why protein becomes increasingly important after 40 • The importance of preserving and building muscle • Why extreme intermittent fasting may not be ideal for every woman • How sleep deprivation affects blood sugar and metabolic health • Why whole foods and processed foods can affect the body differently • How the gut microbiome may influence metabolism and weight Why Calories In, Calories Out Isn't the Whole Story Calories matter, but Dr. Brewer explains why metabolism is far more complicated than simple math. Food quality, insulin response, meal timing, circadian rhythms, stress, sleep, muscle mass, and the microbiome can all influence how the body responds to what we eat. For women who have spent years restricting calories, simply eating even less may not be the answer. Dr. Brewer discusses how she sometimes uses a gradual "reverse dieting" approach to increase intake. Are You Eating Enough Protein? One of the biggest mistakes Dr. Brewer sees is women starting the day with too little protein. A couple of eggs, oatmeal, yogurt, fruit, or granola may sound healthy, but she recommends focusing on approximately 30–40 grams of protein at the first meal. And breakfast doesn't have to look like breakfast. Leftover dinner, fish, vegetables, or other protein-rich whole foods can work just as well. Intermittent Fasting, Muscle & Menopause Intermittent fasting can be useful, but more isn't necessarily better. Dr. Brewer cautions against routinely eating one meal a day or severely restricting eating windows if it makes it difficult to consume adequate protein and preserve muscle. Muscle is metabolically important. It supports bones, glucose regulation, body composition, and healthy aging—making resistance training especially important during and after menopause. The Midlife Exercise Mistake More cardio isn't always better. Dr. Brewer identifies three common problems she sees in women struggling with body composition: • Under-eating • Over-exercising • Not lifting heavy enough weights As hormones change, the body may become more sensitive to stress. Strength training, recovery, adequate nutrition, and sleep may be more beneficial than continually adding more high-intensity exercise. Sleep May Be the Missing Metabolic Tool Sleep isn't optional when it comes to metabolic health. Dr. Brewer shares her own continuous glucose monitoring experiences showing how dramatically her glucose levels can change after inadequate sleep. Prioritizing sleep may be one of the simplest—and least expensive—strategies for supporting blood sugar, metabolism, energy, and weight management. Don't Forget the Gut Dr. Brewer performs microbiome testing on her patients because gut health may reveal issues even when someone doesn't have obvious digestive symptoms. She discusses dysbiosis, microbial diversity, digestion, inflammation, fiber intake, estrogen metabolism, and how medications, antibiotics, menopause, and other factors can alter the microbiome. Key Takeaways • Weight-loss resistance after 40 is not simply about willpower • Chronic calorie restriction may work against your goals • Prioritize protein and preserve muscle as you age • Strength training becomes increasingly important in menopause • Extreme fasting isn't appropriate for everyone • Whole foods should form the foundation of your diet • Sleep has a powerful effect on metabolic health • Gut health may be an overlooked piece of weight-loss resistance Who This Episode Is For • Women gaining weight despite eating healthy and exercising • Women in perimenopause or menopause • Anyone frustrated that previous diets no longer work • Women using GLP-1 medications without expected results • Anyone interested in functional medicine and metabolic health • Women who want to protect muscle and age stronger Guest Resources Dr. ...

    2026/08/04

    Could your thyroid be the missing piece behind your fatigue, weight gain, brain fog, and hormone struggles?

    In this episode of 40s Forward, Dr. Betsy Greenleaf welcomes Dr. Amie Hornaman, widely known as The Thyroid Fixer. As a thyroid expert, author, and founder of the Advanced Thyroid & Hormone Clinic, Dr. Amie shares why so many women continue to suffer despite being told their thyroid labs are "normal."

    Together, they discuss how thyroid health influences metabolism, hormones, energy, mood, and longevity—and why a root-cause approach is essential for feeling your best after 40.

    What You'll Learn in This Episode

    Looking Beyond Standard Lab Tests

    Dr. Amie explains why many patients continue to struggle with fatigue, stubborn weight, hair loss, and brain fog despite being told everything is "normal."

    She emphasizes the importance of looking at the full thyroid picture—not just TSH—to better understand how the thyroid is functioning.

    A Root-Cause Approach

    Rather than masking symptoms, Dr. Amie discusses addressing the underlying drivers of thyroid dysfunction, including chronic stress, inflammation, gut health, nutrient deficiencies, and autoimmune disease.

    When these factors are addressed, many people experience improvements in energy, metabolism, and overall well-being.

    • Symptoms matter as much as lab values.
