Weight-loss drug found to shrink muscle in mice, human cells

I'm not commenting specifically on the heart-muscle aspect of the study, but it shouldn't be a surprise that the weight loss from this drug is significantly attributable to muscle loss; it almost always is when dieting. It's the same with keto/low-carb or any other kind of caloric-restrictive dieting (which Ozempic facilitates).

The modern weight-loss programs I'm seeing now (at least those aimed mostly at middle-aged men) emphasize consuming significant amounts of protein (2g for every 1kg of body weight each day) and engaging in regular resistance training, in order to maintain muscle mass.

The article addresses this:

To keep muscle strong while losing weight, Prado says it is essential to focus on two main things: nutrition and exercise. Proper nutrition means getting enough high-quality protein, essential vitamins and minerals, and other “muscle-building” nutrients. Sometimes, this can include protein supplements to make sure the body has what it needs.

Perhaps there needs to be more formal research into this, and a strong recommendation made to everyone using these drugs that this kind of diet and exercise plan is vital.

I've heard this feedback on Ozempic et al from my wife who is a GP some 6 months ago, when I mentioned how US is too much in comfort zone and addicted to HFCS to actually lose weight permanently, ever, so in good old weight-losing fads fashion they will just throw money at the problem, experiencing somewhat variable success and who knows what bad side effects.

My wife told me exactly this - potentially all muscle mass loss (and she made sure I understood that 'all' part), yoyo effect once stopping, potentially other nasty long term/permanent side effects, and overall just a bad idea, attacking the problem from a very wrong direction. Just look at musk for example - he pumps himself with it obsessively and the results even for richest of this world are... not much there (or maybe his OCD binging would make him 200kg otherwise so this is actually some success).

Then all the folks come who say how to helped them kickstart a positive change, like its something against those facts above. All the power to you, just don't ignore facts out there and don't let emotions steer your decisions. You only have 1 health and it doesn't recharge that much, and that short time we have on this pale blue dot is significantly more miserable and shorter with badly damaged health.
