Same food, same steps, different body

Body composition changes in perimenopause even when nothing about your habits does. That isn't a willpower failure — it's physiology, and there are two levers that genuinely move it.

Muscle mass declines gradually from the mid-thirties, and the rate accelerates through the menopause transition. Less muscle means a lower resting metabolic rate and a different shape at the same weight.

The two levers with the best evidence

  • Resistance training two to three times a week, loaded properly
  • Protein at a level most women are not currently reaching

Both also protect bone density, which matters more in this decade than in any previous one. Cardio is good for you; it is not the lever for this particular change.
