It is great you were able to overcome your aversion to home-cooked meals by taking the matter in your own hands and cooking yourself and being in control of what you cook and how much of it you eat. The next step, obviously, is to stop being a couch potato. If you can afford a little extra spend, I recommend getting a DEXA scan now to establish your baseline and then get another one 6 months later. The goal is not to lose muscle while on semaglutide. Being a couch potato exposes you to the risk of muscle loss and you want to counteract that. So weightlifting, body weight exercises, resistance training will be your friends. Semaglutide does not itself cause muscle loss, but it causes weight loss and if you are not careful about how that weight loss proceeds, it may proceed as muscle loss.
