If I have a fitbit that is already connected to cronometer and logging activity, would enabling theTEF (Thermic Effect of Food) option make the calorie burn estimator more or less accurate?
In General calories burned are actually a range. Both exercise from Fitbit and TEF are “the current best guess” based on population- which means they will vary wildly by both individual and environment. As a single person you can learn “how wrong” the estimation is for you and adjust accordingly but any estimator removes what we call a “degree of freedom” and thus adds an additional necessary correction.
In short: it adds noise which might be helpful if you already know your exercise estimation error rate and are willing to learn the TEF error rate. Or just for fun :)
Your answers are great @posi I think I’ve gotten into the habit of eating all of the calories that chrometer determines for me yes at least for me estimates from my watch are wrong. Sad :( I want to eat all that and I get rewarded for running more lol. Back to listening to my body!
