Diet sodas can increase tummy fat

The data didn't say why diet sodas might play a role in weight gain, but previous research suggests it has to do with the disconnect between the taste of artificial sugars and their lack of calories. The brain is wired to expect a big load of calories when foods taste sweet or fatty. But because diet foods fail to deliver, it throws the brain out of whack. Studies in animals suggest that artificial sweetener consumption may lead to even more eating and weight gain, perhaps in part because it triggers the body to start storing more calories as fat.

Excess weight, especially around the belly, as measured in the SALSA participants, is a risk factor for a variety of ills, including cardiovascular disease and diabetes.

In another study presented at the ADA meeting, researchers found an association between consumption of aspartame, an artificial sweetener found in many diet drinks, and elevated fasting glucose levels in mice.
