Weight, Genes & Obesity

Most Americans scoff at the notion of a genetic component to obesity, thinking fat people can overcome their genes. But it's much more significant and involved than most realize.

The breadth of our individual differences is seen in all our physical attributes, not just skin and eye color, but also our body shape and size. The estimates on the degree of inheritability of weight are at least as strong as that of height. Like height, genes are more significant in the expression of the attribute than environment, but cannot be separated from it. Estimates of the inheritability of height from studies of different populations have ranged from 56 to 80 percent, varying by researcher and study design.

By comparison, M. Borjeson's famous 1976 twin studies in Scandinavia estimated the inheritability of obesity to be 88 percent. Subsequent studies, and reviews of all existing family and twin studies done by researchers at the Virginia Institute of Psychiatric and Behavioral Genetics in Richmond, Va., have consistently shown genes responsible for 50 to 90 percent of our adiposity (fatness).

Obesity and Weight Loss
Obesity is now the "trillion dollar disease". This reflects the social costs of obesity, in health and lost production, as well as the weight loss drug profits that might be made for any pharmaceutical company that finds a drug-cure for obesity. The search for viable weight loss medications continues, although pharmaceutical weight loss products still have significant side effects.
