Wanna reduce belly fat? Eat a diet rich with low glycemic meals (in very general terms, this means low sugar and high fiber). Belly bulge is reportedly strongly connected to a number of nasty ails such as diabetes and heart disease. Nothing you want. But by eating a diet based on whole grains, vegetables, and lean protein (as opposed to white bread, potatoes, and Cap'n Crunch cereal), subjects in one study showed a marked deflation of their spare tire. Think smoked salmon and a large salad piled with organic vegetables instead of fried fish and chips.
