Fuel for working out: Calories intake

I burn about half that at Orange Theory at 135-139 lbs so not surprised at all by that burn. The taller men in my group, even those 100 lbs. lighter than your starting range, seem to burn at least in the 700-800 range, and when you first start out, you definitely have a higher burn because it's much harder for your body in the beginning.

I don't have anything to add about whether you're eating enough (not my area of expertise) but just wanted to say good luck & great job! I have seen the most amazing transformations in my 3 years of doing OTF...it's good stuff!!
