GENES
People with two genetic variants are on average 8.5 pounds heavier
People with variants of the FTO gene and of the MC4R gene are, on average, 8.5 pounds heavier than those who do not have these genetic variants according to a new study of 90,000 people. People with a variant of the MC4R gene were, on average about 3.1 pounds heavier. Those with a variant of the FTO gene were, on average, about 6.2 pounds heavier. And those with variants of both genes were, on average, about 8.5 pounds heavier.
“Dramatically, in a study of almost 6000 children, they found that the effects were almost double those seen in adults,” the press release notes.
“Between the ages of four and seven, this additional increase in weight was the result, almost exclusively, of gain of fat tissue, and not due to gain in muscle or other solid tissues.”
