i would like my 2000 calorie diet to be approximately 50% protein, 25% fat, 25% carbs
all nutritional information includes the exact calories from fat, but it doesn't include the calories from carbs or protein.
for example: my whole wheat pasta has 190 calories, 15 from fat. it has 40 grams of carbs, 8 grams protein, and 2 grams of fat. if i assume that 1 g of carbs has the same amount of calories as 1 g of protein, the calculation is easy enough. there would be about 30 calories from protein and 145 from carbs.
so, is the above assumption accurate? if not, how do i calculate these things?
also, is 50/25/25 a reasonable breakdown for a weight loss diet?
thanks

Here is what you do.
1. Keep track of exactly what/how much you eat, and add together the total grams of protein, total grams of carbs, and total grams of fat.
2. Then, add all three of those together to get a "total grams" amount.
3. Last, divide each of your three individual amounts (protein, carbs, fats...from step 1) by the total (from step 2) to get your percentages.
Let me know if that was confusingBoxing Promoter, keystonebox.com

this isn't confusing
however, i thought the percentages were supposed to refer to the percentages of total calories that came from p/c/f not the percentages of total grams of food. mainly because the caloric value of a gram of protein is different then that of a gram of fat...
but i might be wrong. when people refer to a diet having a certain percentage breakdown of p/c/f aren't they referring to the percentage of caloires from each?

well fat's 9, alcohols 7, protein/carb is 4,
it's simple math
if you're eating 10g of fat, its 90 cals
then 10g of carbs 40 cals
10g of protein 40 cals
the % of fat there would be 90/(90+40+40)= 90/170= 52.9% from fats
But, if you want to get that stupidly anal abotu calcing macros, use fitday or something
