GLP-1 Protein Calculator

GLP-1 medications like semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) are highly effective for weight loss — but STEP trial data suggests that 25–40% of weight lost can be lean mass, not fat. Preserving muscle matters for long-term metabolic health, strength, and how your body looks at goal weight.

Protein is the primary nutritional lever. Higher intake combined with resistance training is the evidence-backed strategy to shift the fat-to-muscle loss ratio in your favor. Muscle protein synthesis (MPS) requires a minimum threshold of roughly 20–40g of protein per meal to trigger a full anabolic response — spreading intake across meals matters as much as the daily total.
