Protect your muscle

The body you keep is the body you protect

Rapid weight loss takes muscle with the fat unless you defend it. Three levers do most of the work. Check in each week — it’s 30 seconds, and what you keep tracks the habits you keep.

Is the weight coming off very fast / from aggressive under-eating?

The three levers (the preservation triangle)

  • Protein — preserves lean mass during weight loss (supported-but-limited). Set a target with the Protein Reality Check.
  • Resistance training — the habit that best survived stopping in the maintenance trial (emerging). Start with the Strength Minimum Plan.
  • Sustainable pace — faster loss costs more lean mass; not a number to chase. A clinician conversation if it feels too fast.
