How muscle affects fat loss on a GLP-1

When appetite drops sharply on a GLP-1, it is easy to under-eat protein and lose muscle along with fat. Muscle is metabolically active, so protecting it matters.

  • Prioritize protein at every meal
  • Include resistance training a few times a week
  • Do not cut calories more aggressively than needed

Keeping muscle helps you look leaner and supports long-term maintenance once weight stabilizes.
