Adherence
Combining incretin-mimetic drug therapy with resistance training and adequate protein intake minimizes skeletal muscle loss and preserves metabolic health.
To keep your muscle while losing weight on GLP-1 drugs, you must lift weights at least twice a week and eat enough protein (aim for 1.0-1.5g per kg of your goal weight). This combination is the only way to ensure the weight you lose comes from fat, not muscle.
GoodSupportsHIGH confidence
Concurrent physical activity, especially resistance training, has been shown to effectively minimize loss of muscle mass and function during weight reduction therapy.

More from this paper
- Incretin-mimetic drugs (IMDs) such as semaglutide and tirzepatide cause significant skeletal muscle mass loss (≥10%) during rapid weight reduction, a loss comparable to 20 years of age-related decline.Good
- Oral nutritional supplements (ONS) containing high-quality protein and micronutrients are an effective strategy to prevent nutrient deficiencies and support muscle health in patients with reduced appetite from IMDs.Moderate
