Eli5: If 1000 cal equals half a pound of fat, how can a food that has 1000 cal weight less then a pound?

Question

where does the body find the extra weight?

In: 0

Answer 1

It’s not exact. In fact, I’ve heard that it’s 3500 calories/ lb of fat. Putting the 1/2 lb figure at 1750 calories, so it’d be easy for 1000 calories to be less than half a pound.

But yes, your body can’t gain more weight than the weight of the food it ingests.
