Perimenopause, Sarcopenia, and Metabolic Change: Strength Training, Protein, and Cortisol with Dr. Betyshia Belardo

In part two of The Girl Doc Survival Guide with Dr. Betyshia Belardo, the conversation focuses on sarcopenia (midlife muscle loss) and how reduced estrogen during perimenopause can contribute to declining muscle mass, lower metabolism, decreased strength, and weight gain with a shift in fat distribution toward the midsection. Belardo emphasizes that women can counter these changes with consistent strength training (even 15–20 minutes, 2–3 times per week), safe progressive overload rather than lifting excessively heavy weights that risk injury, and increased protein intake, recommending about 30 grams per meal while prioritizing whole foods and supplementing as needed. They discuss tracking body composition, adding fiber (about 30 grams/day), hydration, and maintaining enjoyable activity. Belardo explains cortisol’s role via stress and poor sleep, noting sleep deprivation can increase cravings and insulin resistance risk, and advises sleep, self-care, and social connection.
