The Source: Slim Soda Study Shows Swelling Circumference


That diet soda you thought was helping you lose weight might be doing the opposite, according to a new study from the University of Texas Health Science Center.

After examining 749 adults across the city, the San Antonio Longitudinal Study on Aging, a study that has spanned multiple decades, found that consumption of diet soda was linked with increases in waistlines in senior citizens.

It is linked with a lot a lot of weight...three times as much abdominal fat, in fact.

In a striking dose-response relationship, increasing DSI was associated with escalating abdominal obesity, a potential pathway for cardiometabolic risk in this aging population.

The study comes on the heels of recent peer-reviewed work on the link between artificial sweeteners and weight gain. One study in mice found that sweeteners changed gut bacteria makeup and metabolic function which led to weight gain.

What does it mean when caloric intake isn't the only metric?
