Is 4cal/gram for carbs & proteins an exact number?
I'm asking this because I've heard some people saying carbs and proteins have 5cal/g and also..when reading the nutrient info for certain things I buy and do my 4/4/9 calorie math..it doesn't add up properly. Does anyone know if these 4,4,9 numbers are exact? or are they just approximations?

Literally, one of them, I think protein, has almost 5cals/g. Due to inefficiency in the human digestive system, that amount of energy cannot be extracted, so the 4/4/9 is used. This would not be seen on the label, my guess is that you are counting fiber as having caloric weight while the maker of the product is not.
BTW, that 5cal/g comes from Exercise Physiology by Katch, Katch, and McArdle, I believe.If sense were common, everyone would have it.

If you want the "textbook answer" all of these values are rounded down to the nearest whole number.
Carbs contain 4.4 calories per gram, for example.
(Calorie weights? Huh? Calories are a measure of energy. i.e. the amount of energy required to raise the temperature of 1 liter of water by I degree celcius. They have no weight.)The more
