"the statement made that calories from alcohol cannot be used for fuel was facinating. i always thought a calorie was a calorie. if it cant be burned, where then does it go? stored forever? i ask because i drink wine or beer modestly and this freaks me out."
When you have a drink, your body converts about 5% of the alcohol into fat. The rest is converted by the liver into a substance called acetate. Acetate is released into the bloodstream where it blocks the use of fat calories for energy.
Recent research published in the American Journal of Clinical Nutrition reported that fat metabolism can be reduced by as much as 73% after only two drinks of vodka and lemonade in a one hour time period. The double jeopardy is alcohol's storage as fat and its ability to shut down the body's use of fat calories for energy during exercise or other activity. You can see how excess alcohol consumption can contribute to the dreaded "beer belly." So, this is just one more reason to drink alcohol in moderation.
