But most diet programs say calories from booze are counted as part of your
daily 'allowance'.



So lets say we've got 3 identical people. The values given are all daily:

All have the same activity level, they use 2000 calories.

All three consume an additional 1000 calories from the same alcoholic
beverage. Besides the alcohol they only drink water.

They all weigh the same at the start.

Person A: Consumes 1500 calories in food.

Person B: Consumes 2000 calories in food.

Person C: Consumes 2500 calories in food.

According to the figures person (a) consumes 500 calories more per-day then
they expend. Therefore they would gain weight. Is this correct?

If the statement above is true, are slender alcoholics so because of more
complicated reasons other than calorie intake vs calories burnt?
