Technically, it does! CHECK OUT THIS QUICK VIDEO where I explain the "Thermic Effect of Food" -- basically, how many calories it takes to digest each type of food we eat. You might be shocked at how different it is between the various macronutrients (fat, carbs, and protein).
And of course, if you have any questions or need some help with your own customized portions, I'm an email reply away. ;-)
Happy day
