## Metabolic health

- [Ozempic costs no more muscle than any diet, and you can protect what you have](https://sciencebased.news/glp1-muscle-loss/) (2026-09-27): Claim: About 40% of the weight you lose on a GLP-1 drug is muscle. Grade: Not supported. The viral claim that 40% of the weight lost on GLP-1 drugs is muscle mixes up muscle with lean mass. Body scans from trials of 140 to 246 people show the drugs cost about as much muscle as any weight loss of the same size, and strength training is the best protection.
- [A glucose spike after oatmeal doesn't mean oatmeal is bad for you](https://sciencebased.news/glucose-monitors/) (2026-09-27): Claim: A glucose monitor can tell you which foods are bad for you. Grade: Not supported. In controlled NIH studies, the same meal eaten twice gave glucose readings as different as two different meals, so one spike can't judge a food. Brief rises are normal, and the proven ways to protect your blood sugar are simple.
