Possible Test for Obesity Predisposition.

A study of 2,258 10-year olds in the United Kingdom found that children with a genetic propensity towards obesity also had lower satiety responsiveness. This finding could be used to identify children who may be at risk for being overweight or obese and teach them techniques to feel fuller while eating such as controlling portion sizes, eating slower, keeping treats out of sight, and avoiding second helpings.
