<p>Obesity is a chronic, relapsing, and progressive disease that leads to negative health consequences.

The most common obesity phenotypes include: metabolically healthy obese (MHO) and metabolically unhealthy obese (MUO).

Obesity is a chronic, relapsing, and progressive disease that leads to negative health consequences.
