Weight loss can involve losing both fat mass and lean tissue, including muscle. Maintaining muscle matters because it supports strength, mobility, physical function, and everyday activities.

Eat Enough Protein

Include protein sources throughout the day, such as eggs, fish, poultry, Greek yogurt, tofu, beans, and cottage cheese.

Your ideal protein intake depends on your individual needs. A registered dietitian can help you develop an appropriate plan, especially if you have kidney disease or other relevant medical conditions.

Include Resistance Training

If medically appropriate, resistance exercise can help preserve muscle during weight loss. Options include body-weight exercises, resistance bands, weightlifting, or supervised gym programs.

Start at a manageable level and progress gradually.

Avoid Excessive Restriction

Very low food intake can make it difficult to obtain enough protein, energy, and micronutrients. Weight loss should not come at the expense of persistent weakness or declining physical function.

The bottom line: Supporting muscle during GLP-1 treatment involves more than protein alone. Adequate nutrition, resistance exercise, recovery, and individualized guidance all matter.

Discuss exercise and nutrition plans with your healthcare team if you have medical conditions or physical limitations.
