I've wondered this for awhile and this seems like a good time to ask:
Can you gain weight from zero calorie foods?
I can think of it two ways. The first is that since your body doesn't get any energy out of the food through digestion (hence the zero calories), you can't gain any weight because there is nothing for your body to convert to fat, muscle, or anything else. The other way I can think of it is that there are zero calorie items, such as vitamins and minerals, that do not impart calories to your body yet are absorbed and would thus add weight (however small) to your body. So does something like Diet Coke have stuff in it that is absorbed into your body even though it's zero calorie?
I hope that makes sense. Does anyone know?
