It's not You, It's the "Gene"

Researchers finally found a gene, called FTO, common in the population that dictates why some people gain weight while others do not. The presence of a version of FTO increased a person's risk for obesity, and it was very common in the people studie - 63 percent had one or two copies of it. People with two copies had about a 70 percent higher risk of being obese than people with none and were an average of nearly 7 pounds heavier than a similar person with no copies. Those with one copy had a lesser but still elevated risk. SOURCE
