Who these studies look for
Most of these studies set a BMI range and may exclude people taking certain weight-loss medicines or who have had bariatric surgery. Some require a weight-related condition such as type 2 diabetes or high blood pressure.

Questions
Can I join a weight loss study if I already take a GLP-1 medicine?
It depends on the study. Many exclude people currently or recently on weight-loss medicines; others are designed specifically for them. The listing’s eligibility criteria and the study team are the only reliable answer.
