Alcohol
 

One gram (1 ml) of alcohol contains 7 calories. For example: 1 liter of sweet wine (15% alcohol, 15% sugar) contains 150 ml of alcohol (= 1050 calories) + 150 g of sugar (= 600 kcal) = 1650 calories per liter. As a comparison: non-fat milk contains only 340 calories per liter and orange juice contains 425 calories per liters.

Alcohol has a very high caloric density of 7 calories per gram, and is easily converted into body fat. It is rather easy to drink relatively large quantities of it, and it invites to drink more as it tastes so well. One liter of sweet wine (15% alcohol, 15% sugar) contains 1650 calories. People who want to lose body fat should avoid drinking alcoholic drinks.
