I guess it depends what exercise you're doing? Most of mine is plunged into my weekends where I might cycle for maybe 5 hours. I don't think I could survive on base cals after that.Eating back calories burned through exercise is where so many peolpe go wrong with consistent weight loss goals.
I think this is closer to what I do. I accept if I've burnt 2k cals in the morning, I am going to need to eat a bit more, but not 2k's worth!Interestingly Noom only gives you back half of the calories burned through exercise.
