Calories are a unit of heat, and absorbing nutrition is a biological process. Unless you're a bomb calorimeter, they have very little to do with what goes on inside you after you eat. I urge you to reconsider what food you choose to eat.

You should absolutely desist from saying that other people should not avoid UPFs, because that is a harmful statement in the same vein as "you don't have to stop smoking."

You are like 25 years behind the science. There is a difference in absorption, but its negligible. Your digestion is incredibly efficient at absorbing calories. Unless you have some weird condition, you can count calories 1:1 and ignore the rounding error of absorption.

This calorimeter talking point has been debunked for a long time now.
