How many calories can make you gain a pound?!
Question:
How many calories can make you gain a pound?
Answers:
Although it takes about 3500 calories to LOSE a lb of fat, it takes about 4090 calories to GAIN a lb of fat. The 4090 calories per lb equates to about 9 calories per gram when converted to metric. That is why there are 9 calories per gram of fat (and not 7.7).
The difference between losing and gaining is due to the second law of thermodynamics which states that energy always gets wasted when it is converted from one form to another.
