PSMF Series: How Hormones Change Fat Loss, Muscle & Metabolism After 40 with Maria Emmerich

Why does fat loss suddenly feel harder during perimenopause and menopause—even when you're still exercising and watching what you eat? In today's Protein-Sparing Modified Fasting Series episode, I'm joined once again by bestselling author and nutrition expert Maria Emmerich for a fascinating conversation about hormones, metabolism, protein, muscle and body composition in midlife.

We discuss how changes in estrogen, progesterone and testosterone may influence insulin sensitivity, sleep, motivation, muscle retention and fat distribution, and why preserving lean mass becomes increasingly important as we age. Maria also shares why she believes prioritizing protein, resistance training and a lower-fat approach can be especially helpful for women struggling with body composition during menopause.
