Losing Weight on Injections? Don't Lose Your Muscle Too

Weight-loss injections work, but not all the weight you lose is fat. Funny how that never makes the advert.

How much is muscle?

In the main trials, roughly a quarter to two-fifths of the weight lost was lean mass, which includes muscle.1,2

Why it matters

Less muscle means less strength and a softer shape. It can also make the weight harder to keep off.

How to keep it

  • Strength train 2–3 times a week, gradually getting heavier.3
  • Protein first at every meal. Appetite drops, so it's easy to under-eat it.
  • Stay active, sleep well, stay hydrated.
  • Keep your doctor or prescriber in the loop. They manage the medication; I manage the training.

Do this and more of what you lose is fat, and you come out of it stronger.
