Somtimes not knowing what is in something is a good thing. My brother for instance loves margaritas. Nothing is better than a night out with a few Cadillacs. One, two, three maybe four.
My brother also lifts weights and runs a little. He can't figure out why he the small rubber tire around his waist is inflating. Hmmm, well it could be the extra 1,600 calories getting sucked down. And that is assuming a pretty humble 400 calories per delicious cocktail. A large size margarita easily packs about 600 or more calories.
