Consumption of diet drinks has doubled among US children over the past decade. Aspartame kids better than sugar babies?
I'm no doctor, and population-based evidence seems to suggest this isn't the case, but I always had a hard time believing sugar was a major culprit in weight gain.
From what I picked up in biology, simple sugars are the smallest, lightest, easiest-to-burn things animals regularly consume. It takes a LOT more work (chemically speaking) to break down proteins or more complex carbohydrates than it does to just burn sugar. Glycolysis is what... 9 steps? That's really short, compared to a lot of the insane reaction chains going on.
Shouldn't simple sugars be the first things to burn away? Quickly and easily with even the slightest physical activity?
