Macro partitioning
Preservation of lean mass during GLP-1/GIP-induced weight loss requires high-quality protein distribution (1.2–1.5 g/kg/day) and resistance exercise to mitigate sarcopenia and maintain oncologic treatment tolerance.
To prevent muscle loss while on GLP-1/GIP drugs, eat 1.2–1.5 grams of protein per kilogram of body weight daily, spread across meals, and engage in regular resistance exercise.
GoodSupportsHIGH confidence
Rapid pharmacologically assisted reductions in body weight can improve the metabolic milieu yet jeopardize lean mass without targeted support. Practical levers include distributing high-quality protein across meals (often in the ~1.2–1.5 g/kg/day range in at-risk adults...), pairing therapy with progressive resistance exercise...
Why this rating
Strong mechanistic rationale and clinical guidelines support, though direct RCT evidence in GLP-1 oncology populations is sparse.
