If there are 9 calories in 1 gram of fat, 4 in 1 gram of carbs, and 4 in 1 gram of protein, you should theoretically be able to calculate the calories in a food item by knowing the fat/carbs/protein numbers. Why doesn't this work? For example, they're ordering from Pat & Oscar's tonight at work and I was looking at the nutrition facts for 1 breadstick. They're so fucking good, but I just can't do it. My point is, the numbers don't equal the calories:

240 calories
6 grams of fat
39 grams of carbs
6 grams of protein

If you calculate the calories using the grams of fat/carbs/and protein, you'll come up with:

54 calories from fat
156 calories from carbs
24 calories from protein
= 234 calories

I realize the difference is small, but it exists nonetheless, and I noticed this on many food items. My question is: why?

I'm sure the 9, 4, and 4 numebrs aren't exact either. Rounding's a bitch.

yep, rounding. it's legal to list anything under .55 as 0 for example.

*correct me if I am wrong but the following was passed down to me from a friend

Yeah and with some things like chips for example you're allowed to list a small quantity that will have ~.5 so it can be listed at 0.

For example Trans Fats
Serving = 6 Chips
Lets assume 6 chips have .5g of trans fats then they are allowed to list it at 0. HOWEVER who only eats 6 chips?

Its just like marketing.

For example 79.99 is much more appealing than 80.00

Just ways of companies manipulating you in order to get you to buy their products/feel better about yourself.

Think of a number between 5 and 12

Were you thinking of 7?
The majority of people do.

Also not all fats are 9 cal, some are 10, and some are just 6 (MCT medium chained fats, such as safflower and coconut)

Some sugars such as sugar alcohols come in at 3 cal, while high frutcose corn syrups can hit 5 cal
