Weight Gain in Perimenopause Over 35: Why Your Body Is Changing and What Actually Works

If you’re experiencing weight gain that feels sudden, unexplained, and resistant to everything that used to work—especially after age 35—you are not alone. For many women, weight gain in perimenopause begins years before menopause is ever mentioned in a doctor’s office. Alongside changes in weight, sleep often deteriorates, anxiety increases, cravings feel harder to control, and energy becomes unpredictable.

In this episode of The Dr. Brighten Show, Dr. Jolene Brighten breaks down the real hormonal mechanisms behind weight gain in perimenopause over 35—and why this phase of life requires an entirely different approach than “eat less and move more.” This conversation focuses on the biological changes happening beneath the surface, how hormones like progesterone, estrogen, cortisol, insulin, and thyroid hormones interact, and what women can do to support their metabolism, sleep, and overall health during this transition.

This is not about willpower. It’s about physiology.
