THEORY #2: ADJUST FOR PARTIAL ABSORPTION OF FIBERįiber is only partially digested by the human body.Īnd, while it is difficult to pinpoint an exact energy yield in calories per gram (this depends on many factors including fiber type), I suspect MFP might be adjusting for fiber in their calorie calculations. Normal Human Language: We are going to reduce the number of calories that we expect to burn through digestion. We will take the average TEF rate (27.5%, 10%, and 2.5%, respectively) and recalculate the calories in our 40 randomly selected foods. These MFP geniuses are getting ahead of themselves! They are accounting for TEF! This has to be it! The most calories are burned when we eat protein (20-35% of the calories we consume), second most when we eat carbohydrates (5-15%), and the fewest when we eat fats (0-5%). We burn calories via digestion this is called the thermic effect of food. THEORY #1: MFP ADJUSTS FOR THERMIC EFFECT OF FOOD When I nail my macros, I want to see that calorie number on point.īut before we write MFP off as completely incompetent, let’s see if there is a method to the madness.
