How come weight is affected by calories, and not the weight of the food? If I eat a bag of candy, I will gain weight, but if I eat 4 apples, I won’t gain as much?
In: Biology
You excrete the mass of the object after you consume it. When you drink a litre/kilogram of water, you will initially show a kilogram heavier on the scale. However, you will eventually piss out, sweat, exhale, etc. that water and return to the weight that you were at before. Drinking water isn’t “true” weight gain because it is a temporary change.
Body mass is gain from calories, and calories alone. If you eat more calories than you burn, those calories convert to fat and store within your body for use at a later time. Apples have less calories per weight than candy. When you eat apples, you will end up excrete most of that weight right back out.
