I'm a Crossfitter and have heard that I should be getting my calories as follows:
40% Carbs 30% Fats 30% Protein.
My question is: how do you calculate what counts towards what?
Easy example a dozen eggs:
Calories Fat Carbs Protein 12 Egg 720 60 6 72
How many of the 720 calories count as "Fat" calories?
720 * ( 60/(60+6+72) ) = ~313?
Follow up question (may repost): How the hell do you get 40% of your calories from veggies? Assuming you don't want to go into the realm of grains, 40% seems steep.

- 1g of fat contains 9kcal of energy
- 1g of protein contains 4kcal of energy
- 1g of carb contains 4kcal of energy
So if you have 60g of fat, 72g of protein and 6g of carb, the total energy is: 60*9+6*4+72*4= 852kcal *
- Fat % = 60*9/852 = 63%
- Protein % = 72*4/852 = 34%
- Carb % = 6*4/852 = 3%
*Where the 720kcal comes from is a bit of a mystery. Are you sure you wrote the numbers down correctly?
You can easily get 40% of energy from carbs by eating starchy vegetables such as potatoes and sweet potatoes and nuts.
