People lost the same amount of weight with tirzepatide and apitegromab—but kept 40% more muscle than those on placebo. Blocking myostatin didn’t slow fat loss, it just saved the muscle. That’s not a side effect, it’s a targeted rewrite of how weight loss works. https://fitbodyscience.com/post/bluesky/springernature.com/post-3mnsfhif?utm_source=social_reply&utm_medium=bluesky&utm_campaign=autopost
Very strong evidence
Multiple randomized or controlled trials back these claims.
A new drug might help you lose weight without losing muscle.
When people took apitegromab along with tirzepatide, they lost just as much total weight as those on a placebo—but kept more of their muscle. That’s surprising because usually, when you lose weight, you lose muscle too. Blocking this protein, called myostatin, seems to protect muscle tissue without slowing down fat loss. It’s not just theory; the data shows a real difference in body composition. This could matter a lot for people trying to lose weight and stay strong.
So if you’re on a weight-loss drug and worried about losing muscle, this might be a promising step forward.
