JJ Virgin says GLP-1s work for weight loss by improving insulin sensitivity and increasing satiety, but losing weight without building muscle is like deleting files while keeping malware. Eat protein first and do resistance training, or the drugs may do more harm than good.
If you're losing weight on a GLP-1 but you are not building muscle, it's sort of like deleting old files on your computer but keeping the malware installed. Think of a GLP-1 as a tool. It can help you improve insulin sensitivity, it can improve satiety, but while you're using it, you also want to make sure that you are eating protein first and doing resistance training so that you are losing fat and holding on to— or better yet, building muscle. If you're doing all that, GLP-1s can be a great benefit. Without it, they can be detrimental.
