The Bit Nobody Warns You About
When you lose weight fast, not all of it is fat. Up to 30% can be muscle. Muscle keeps you strong, keeps your metabolism ticking, helps with blood sugar and balance, and keeps you moving well as you age. Lose too much and weight is harder to keep off, and you feel weaker, not better.
The fix is simple. Eat enough protein, even when you don’t feel like eating much. That’s the whole game.
