How can you preserve muscle during a cut when GLP-1s make eating difficult?

A calorie deficit makes preservation of muscle more challenging, especially if appetite suppression also reduces protein intake and training quality. In a controlled trial combining a marked deficit with intensive exercise, the higher-protein group had better lean-mass outcomes than the lower-protein group. This supports paying attention to intake quality, not simply making the scale drop faster.[1]

That experiment was not a trial of GLP-1 drugs in advanced enhanced bodybuilders, so its exact results should not be promised in that setting. Lean-mass changes also include water and glycogen. Strength trends, training tolerance, and longer-term body composition help distinguish a temporary flatter appearance from meaningful tissue loss.[1]

Practical priorities are a tolerable deficit, consistent resistance training, and meals that make adequate protein achievable. If prescribed appetite suppression prevents normal nourishment, review the treatment with the prescriber. Adding an anabolic compound is not a proven substitute for correcting inadequate food intake.[1]
