Washington, Jan 9 (ANI): It's not just what you eat that makes
those pants tighter - it's also genetics, researchers have
claimed. In a new study, scientists discovered that body-fat
responses to a typical fast-food diet are determined in large
part by genetic factors, and they have identified several genes
they say may control those responses. The study is the first of
its kind to detail metabolic responses to a high-fat, high-sugar
diet in a large and diverse mouse population under defined
environmental conditions, modeling closely what is likely to
occur in human populations. The researchers found that the
amount of food consumed contributed only modestly to the degree
of obesity. "Our research demonstrates that body-fat responses
to high-fat, high-sugar diets have a very strong genetic
component, and we have identified several genetic factors
potentially regulating these responses," first author Dr. Brian
Parks, a postdoctoral researcher at the David Geffen School of
Medicine at UCLA said. "We found that
