The Problem With Obesity in Families

Professor James discovered that even in developing countries places as far apart as South America and Polynesia people were suffering from obesity. With more research he also discovered a further problem the fact that obesity seemed to run in families. If you have identical twins and they're separated within months of birth and brought up completely separately then studied when they're 20, 30, 40 years of age they're almost the same weight and height so that means that there is a genetic propensity for gaining weight.
