What the guideline says
- When you lose weight, some of what you lose can be muscle rather than fat, whether the loss comes from eating less, from a medication such as semaglutide or tirzepatide, or both.
- The current Dietary Guidelines for Americans set a target of 1.2 to 1.6 grams of protein per kilogram of body weight per day.
- For a person who weighs 170 pounds, about 77 kilograms, that is roughly 90 to 125 grams of protein a day; your provider may set a different target, especially if you have kidney disease.
- A solid source of protein at every meal makes the target easier to reach than one large dinner.
- On low-appetite days, eat the protein on your plate first and choose soft or high-protein options such as yogurt, eggs or a protein shake.
- Two or three strength sessions a week with weights, resistance bands or body-weight exercises signal your body to hold on to muscle.
