You are doing all the same things you did in your 30s. The problem, however, is that the scale is suddenly creeping up. It feels like your body has betrayed you. This frustration is incredibly common. Consequently, many women over 40 believe their metabolism is just “broken” and that weight gain is inevitable. This is simply not true.
The truth is, your body’s rules change. As we age, muscle mass naturally declines. This process, called sarcopenia, slows your resting metabolic rate. Therefore, the daily habits that used to work fine are now secretly wrecking your metabolism after 40. You are not broken; you just need a new playbook.
