more nutrition spreadsheeting. given the amount of macronutrients in a food, how many calories are contributed by carbs (k), fat (f) and protein (p)?
one surprise is that powdered broccoli would make a decent protein source of plant protein. but you'd need quite a lot of broccoli per kilogram of powder because it contains so much water, so it would be quite expensive.

@thor when you say protein quality... quality in what way? What are the measurable objective ways a protein of higher quality is superior?
> the calorie content of protein is the same as that of carbs, about 4 kcal/g, but those calories don't make you fat. they build muscle and other tissues. so if you're counting calories to lose body fat, the calories from protein can be subtracted from the total.
This one is a bit complicated, not to say your wrong, but its less direct than all that.
Calories are calories and if you eat more calories than you burn you gain weight. That si just as true of protein calories as it is of carb calories.
The difference is in your insulin response, which effects how quickly you get hungry. The effect of insulin from carbs will make you get hungry much faster and ultimately cause you to eat more calories (Well that and it is quicker to digest). The end result is if you eat carbs you tend to eat more calories and thus tend to get fat.
@freemo yes. and you're going to be eating a lot of legumes, such as soy. protein quality is a thing. i've been investigating that, and just about the best protein you can get is casein. milk protein.
the calorie content of protein is the same as that of carbs, about 4 kcal/g, but those calories don't make you fat. they build muscle and other tissues. so if you're counting calories to lose body fat, the calories from protein can be subtracted from the total.
if you do this for something like a Swiss cheese, you'll find that about half of the calories are from protein.
