It sounds like a simple solution to a complicated problem: Find out what kind of obesity you have based on a one-time genetic saliva test. Then you and your doctor can get a better idea if anti-obesity drugs or other treatments are more likely to work for you.
The goal of creating the obesity types and test is to increase chances you’ll lose weight and improve your health and well-being, vs. a one-strategy-fits-all approach. It’s what Mayo Clinic researchers had in mind when they created four phenotypes of obesity.
