“One of the big mysteries with popular GLP-1 medications for weight loss is why some people will lose 20% or more of their starting body weight on the drugs while for others, the scale will barely budge.

One study found that about 1 in 7 people who used semaglutide – which is approved for weight loss under the brand name Wegovy – for more than a year didn’t lose at least 5% of their starting weight, indicating that the drug didn’t work well for them.

Now, research suggests that the answer may lie in a person’s genes.

The study shows that a new test that assigns a genetic risk score may be able to help people figure out whether they are likely to be successful on injected weight loss medications.”
