#1 Why Women Lose Muscle Faster in Perimenopause

Can't lift what you used to, even though your labs look normal? Dr. Remina Panjwani breaks down a 2025 Deakin University study showing that muscle loss in women tracks with estrogen and progesterone, not age, and why it often speeds up around perimenopause and menopause. She covers why sarcopenia can start earlier than expected, what grip strength says about long-term health, and how protein and resistance training can help.
