A small number of extremely overweight people may be missing the same chunk of genetic material

Imperial College London scientists found dozens of people - all severely obese - who lacked approximately the same 30 genes. The gene "deletion" could not be found in people of normal weight. While much of the "obesity epidemic" currently affecting most Western countries has been attributed to a move towards high-calorie foods and more sedentary lifestyles, scientists have found evidence that genes may play a significant role in influencing weight gain in some people.
