> Together these data indicate that the reduction in cardiac size induced by semaglutide occurs independent of weight loss.
Which does sound concerning. It's the drug, not the weight loss, that causes the muscle loss.
I guess the question is whether it's better than nothing. Is the loss in lean muscle a worse outcome than remaining obese?
As a coder, I'm realising more and more that the human body isn't so different from a computer. When you try to fix something without having complete understanding of all the relevant parts of the system, you will invariably introduce new issues. With a machine as complex as the human body, it seems inevitable that the field of medicine would be a game of whac-a-mole. Finding solutions which don't create new problems…
Although, "single cosmic ray upset events," are just as devastating.
> emerging research showing that up to 40 per cent of the weight lost by people using weight-loss drugs is actually muscle That's the sort of headlines that smells like bullshit to me. My understand of those drugs is that they don't actually make you lose weight, they just cut your appetite so you can follow a diet to lose weight without hunger hammering at the door. So to start with, if that's the case, all they are…

My understanding from initial anecdotes is this is actually literally wrong. Which was surprising to me, too. But people on GLPs tend to prefer more nutritious food (high protein and high fiber). I'm not sure if this has been studied directly in clinical trials yet but I know that food manufacturers have been reorienting their products toward healthier meal configurations in response to the GLPs.
I predicted the exact opposite of this, but so far I appear to have been wrong.

Yes it is.
> It requires extreme diets like a protein sparring modified fast where 80%+ of your calories are from lean protein while running a 50% caloric deficit.
I’m not any sort of expert but that sounds frankly, dangerous. I don’t see how you do something like that without damaging your liver.
It’s very possible to lose weight and gain muscle, but you have to be at just the right body composition (not lean and not obese) and then there’s a question of “over what period of time”?
Any duration under a month is probably pointless to measure unless you have some special equipment. Any duration over a month and it’s kind of obvious that it is possible. Eat a balanced diet without junk, work out regularly, and keep the calories to only what is necessary.

Yea, except without error checking, and fully analog technology. Although, "single cosmic ray upset events," are just as devastating.
Beyond specific diseases we understand, it's still mostly a total mystery why we aren't immortal- we have not yet identified what is the basic mechanism of aging, or why it happens at different rates in different species, and mostly our systems are fundamentally capable of repairing and regenerating almost anything, but for some reason get worse and worse at doing so over time. Moreover, this doesn't seem to happen in all organisms- there are many animals that live ~4x human lifespans, and at least one species of jellyfish that is biologically immortal.
Earlier quoted context omitted.

>Losing weight without losing muscle mass is very hard. I was with you up to here. In my experience it's easy to maintain a huge proportion of your lean tissue during a weight loss diet: Do some resistance training, get some protein, and don't lose weight too quickly. There's no need to go to the extreme of a PSMF - which will still have you lose a bunch of muscle on account of being too big a deficit. If you can kee…
> Do some resistance training, get some protein
jeez, if people actually did that they wouldn't need the drug to begin with
