I read an article the other day that said that the body uses 120 calories to process a 12 oz glass of ice water. So for every glass of ice water that you drink, you burn up 120 calories. So, I wondered if that would also work for ice cold beer? Think of it this way, if a 12 oz can of ice cold beer has 120 calories and you body burns up 120 calories on the beer, then you net calorie gain is 0. And while you aren’t losing any weight, you could drink beer all night and not gain any weight. It must be the pretzels that cause the weight gain.
