Drinking a liter of soda a day for 6 months increases the amount of fat that will accumulate in the liver, muscles, and abdomen by 25% according to a December 2011 article published in the AJCN. This has been linked to the metabolic syndrome, the precursor of type 2 diabetes, and all of its complications that include hypertension, heart attack, stroke, and obesity. High fructose corn syrup turns into fat 40% more than glucose whether with a meal or taken alone. High levels of fructose in the brain stimulate the appetite too. If you're going to consume fructose in any form or sugar, it is important to exercise to burn it off rather than convert them into fat.
