> then they have "too much muscle" as typically needed for their body mass

It's a leap to suggest that it's "good" to lose this muscle mass. If you're obese then it's good to lose fat. It's even better to do so while maintaining muscle mass.

Yeah, but whether you do resistance training while losing weight so that you have proportionally extra muscle mass than you had when you were overweight has nothing to do with the GLP-1 drug.

Every time GLP-1 drugs come up, the convo splinters off into topics that have nothing to do with anything unique to the drug. Now we're just talking about general weight loss and that it's good to exercise. Which is a trivial claim.

Yeah that's obviously better. They really meant it's "not bad" rather than "good".

When people read "muscle loss" they think "oh it's going to make me weak and feeble".

The problem is it is bad. People aren't just losing a proportional amount of muscle to fat mass to keep a good ratio - rapid weight loss is more catabolic towards lean body mass than it is with slower weight loss.

And most obese people are below optimal levels of total lean body mass overall even before this - their leg muscles being larger than an untrained person of the same height and an average weight does not mean that their leg muscles are of optimal size, much less the rest of their body.

Sarcopenia is a real risk for any obese person who is rapidly losing weight and GLP-1s are no exception.

Well, no, but I like how muscular I look (even with the extra weight). I wouldn't want to look skinny and lose the weight lifting gains.
