IS there such an info out there about kcal needed to digest meat vs. carb vs. fat vs. fruits and veggies?

Question

Because meals produce such sleepiness, I want to see what I can do about this! I want to compare the cost (of digestion in kcal) vs. calories and energy gained.

Answer 1

everybody's body would burn a different amount of calories digesting foods depending on their BMR

in terms of the thermogenic effect that foods have. animal proteins have the greatest thermogenic effect, then complex carbohydrates then fats.
