## Resource

In this episode of 40s Forward, Dr. Betsy Greenleaf breaks down why weight gain and weight loss resistance become so common after the age of 40. Despite eating less and exercising more, many people find their bodies no longer respond the way they used to. This episode explains why that happens and what truly works for sustainable fat loss and metabolic health in midlife. Dr. Greenleaf discusses the hormonal, metabolic, and muscle-related changes that drive weight gain, why under-eating and over-exercising sabotage progress, and how modern tools like weight loss medications and peptides fit into a comprehensive strategy. Key Topics Covered: • Why "eat less, move more" fails after 40 • Hormonal shifts that drive fat storage • Muscle loss and metabolic slowdown • Insulin resistance and stress hormones • Weight loss plateaus and metabolic adaptation • Why under-eating backfires • The role of strength training in fat loss Weight Loss Medications Discussed: • Semaglutide • Tirzepatide • Retatrutide Key Points on Weight Loss Medications: • These medications can reduce appetite and food noise • They improve insulin sensitivity • They do not build muscle • Without muscle protection, metabolism can slow • They are tools, not cures Peptides & Muscle Building: • Introduction to peptides used for muscle preservation and recovery • Why muscle is critical for long-term weight loss • Deeper discussion planned in future episodes Why Plateaus Happen: • Metabolic adaptation • Loss of muscle mass • Chronic stress and elevated cortisol • Inadequate recovery • Repetitive exercise patterns What Actually Works After 40: • Strength training as a foundation • Adequate protein intake • Eating enough calories to feel safe • Hormone optimization • Stress and sleep regulation • Personalized, precis…
