Lean Mass Loss on Semaglutide Needs Attention

The STEP 1 trial scanned 140 people with DEXA over 68 weeks. On semaglutide, body weight fell 15% and fat mass fell 19.3%, which is the part that gets talked about. Lean mass fell too, by 9.7%. Lean mass is not all muscle, but a real part of it is, and that number gets much less attention than it should. The drug does what it says. The risk is in how people eat while they are on it. Appetite drops, sometimes a lot, so people eat less of everything, and protein is usually what falls short first. Protein also does little for muscle on its own unless you train, so the two have to go together. A proper meal on these drugs is simple. Put the protein on the plate first and build the meal around it, whether that is chicken, fish, eggs or legumes. Add vegetables next, and let the carbs take whatever room is left, which on a smaller appetite is often not much. Smaller meals are fine as long as protein is the base of each one. Then add two or three strength sessions a week to hold on to the muscle you have. Where do you see the bigger gap in how people on GLP-1 are supported, the food or the training?
