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?
