Can't resist fresh doughnuts? If you give in too often, they can bulk up your belly. Better to share or stop at one. A glazed doughnut has 260 calories. The whole box packs 3,120 calories. A 200-pound man would have to run about 25 miles to work that off, or that's a lot of time in the gym. If you must have a carbohydrate 'fix'. Take 2 So Slim Phaseolin tablets just before you eat. Phaseolin is a completely natural starch and carblocker.
