On a GLP-1 medicine

With a smaller appetite it's easy to fall short. Eat the protein part of each meal first, and spread it across the day. Pair it with strength training 2 to 3 days a week to protect muscle. More: protein on a GLP-1.

  1. Not all the weight you lose is fat. In trial body scans, roughly a quarter to two-fifths of weight lost on GLP-1s was lean mass.
  2. Eating enough protein and doing strength training both help protect that muscle while the weight comes off.
  3. A common target while losing weight is 1.2 to 1.6 grams of protein per kilogram a day. At 180 lb that's about 98 to 131 grams.
  4. Split it across meals. About 30 to 45 grams at each of three meals is far easier than catching up at night.
