GLP-1 receptor agonists can slash your appetite so dramatically that you could go all day without the drive to eat or drink. But your body still needs enough calories to keep your processes humming. Protein, especially, is crucial for preventing muscle loss. (Over time, loss of muscle mass impacts strength, metabolism, mobility, immune function and wound healing.) You need 1 gram (g) to 1.5 g of protein per kilogram of body weight per day.

If you weigh 200 pounds (90 kilograms), your body needs 90 g to 135 g of protein per day—about the amount in a three-ounce salmon fillet…a six-ounce skinless chicken breast…three eggs…and a can of black bean soup.

Eat portions of protein every three to four hours. This is especially important when starting these medications as the body adjusts to treatment. Protein shakes or bars may be more palatable when your appetite is low.
