Fat but fit – Slim but fat These two words read quickly. may not understand Roughly speaking, fat people can be healthy, and thin people aren’t always healthy. Why is that?

But there is no change in the body as an obese person. Normal insulin levels and responses Inflammation at normal cellular level normal blood cholesterol. And the risk of diseases that come with obesity is not different from that of the general population. This group has a medical name. Metabolically healthy obese or MHO translates into Thai simply as obese but fit people. 

On the other hand, another group of people had normal weight. But when the physical examination return with high blood cholesterol high blood sugar have insulin resistance or may have fatty liver mask even though they do not look fat This group of people we call Metabolically obese but normal-weight or MONW translates into Thai simply that normal weight people secretly fat. 

The main reason explaining this scales reverse phenomenon. This is explain by the type of fat that accumulates in the body. 

The first type of fat is Subcutaneous fat is the fat that we pick up from the skin on the back of the arms, thighs or abdominal wall. This type of fat is tangible but not scary. because it does not increase the risk of chronic diseases such as diabetes , coronary heart disease like another type of fat
