We have powerful new medicines that can help people lose a lot of weight, but many stop taking them because they feel sick or don’t get enough support. Some also lose muscle, and weight comes back when they stop. Scientists are working on even better medicines that might fix these problems.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

A new weight-loss drug called retatrutide might help people with obesity lose about a quarter of their body weight in less than a year—and it could work even better and faster than weight-loss surgery or other medicines we have now.
A new weight-loss drug called tirzepatide might help people with obesity lose about 23% of their body weight in a year and a half — possibly even more than some weight-loss surgeries.
A diabetes drug called tirzepatide can help people lose up to 21% of their body weight, but the weight loss tends to stop increasing too soon — especially for those with type 2 diabetes.
