Weight loss can include some loss of lean mass. Here is what is known, and the everyday habits that may help Dallas adults on a GLP-1 medication support their muscle.
When people lose weight by any method, some of that loss can be lean mass, including muscle. Many Dallas patients ask what they can do about it while taking a GLP-1 medication.
What the research shows
In clinical trials of semaglutide and tirzepatide, body composition sub-studies found that most of the weight lost was fat mass, with a smaller share coming from lean mass. Lean-mass changes vary by person, and the long-term effects of this loss are still being studied. The main trial reports are STEP 1 (NEJM 2021) and SURMOUNT-1 (NEJM 2022).
Habits that may help
- Prioritize protein. Ask your provider or a registered dietitian how much protein is right for you, especially if you have kidney disease.
- Add resistance training. Strength exercise, such as weights, bands, or bodyweight moves, two or more days a week is commonly recommended for adults, and it may help maintain muscle.
- Stay hydrated. Dallas summers make this especially important, and dehydration can worsen GLP-1 side effects.
- Do not skip meals entirely. A reduced appetite can make it easy to under-eat, so small, protein-forward meals may help.
- Get enough sleep. Sleep affects appetite and recovery.
