The Truth About Weight Loss Medications and Your Muscle Mass
You start taking a GLP-1 and the scale finally moves. You feel lighter, your clothes fit better, and then someone tells you that a third of what you lost might have been muscle. The reality is more nuanced than the headlines suggest. When you understand what actually drives muscle loss during weight loss and what you can do about it, you can keep the results you want without sacrificing the strength that keeps you independent. Here's what you need to know.
The New Era of Weight Loss

For millions, that has been life-changing. But when you lose weight fast without training, a big share of what leaves your body isn’t body fat, and it’s one of the strongest predictors we have of how long and how well you live.
