So recently I have been going on a cut and of course been using cronometer to track my calories. Importantly I want to make sure I lose weight at a slow and steady pace as I don't want to lose muscle. However I recently noticed there is a feature to turn on TEF. Turning that on showed I was in a caloric deficit of ~200kcal more than I had originally thought. However looking at the forums made my confused as to whether I showed have the feature on or off. For example I saw a post saying that TEF is already calculated in the Mifflin st jeor equation. Does that mean I am calculating TEF twice if I have it on or not?
Essentially if I want to be very precise in measuring my caloric intake, do I turn on TEF?
