So /fit/

A lot of sources online, /fit/ included, claim that a lb of fat is 3500 calories.

But... if 1g of fat = 9 calories, and there's 454 g in 1 lb,

then wouldn't 9 calories x 454 = 4086 calories to a lb of fat?

Is there something I'm missing here?

Pic related, it's me! (just kidding)

body fat and food fats are different if im not mistaken.

1 lb of body fat has the added bonus of having some water thrown in, so the extra weight without extra calories comes from water.

"When we burn fat, or other nutrients, heat is produced, which is measured in calories. Each gram of fat generates 9 calories, and 454 grams equals one pound. But a pound of fat is not all fat. It's about 10% water. All of our body tissues--fat, muscle, bone, skin--contain some water. And water has zero calories.

"In addition, not all the nutrients we eat are completely absorbed from the digestive tract to meet metabolic needs. In the case of fat, roughly 5% is eliminated in the feces. This 10% water content and 5% non-absorbed fat accounts for the 15% difference between the calculated 4086 calories and the actual 3500 calories in a pound of fat."

OP here, found google, lol my bad. Still might interest other people, I guess.
