I'm sure this has been asked before and although I've searched I just haven't found the answer, so I apologize in advance if this is a redundant question.
I've been pretty well versed in the PB/Paleo lifestyles and have recently made my journey into the IF world. I try to follow a condensed eating window with a daily IF of approx. 13-16 hours. I have no troubles doing this, especially since I've been following the reduced carb intake of around 50g a day. One thing I've noticed is that I find myself only feeling the desire to eat 2 times a day on most days.
I follow a 2 on/1 off, 3 on/1 off crossfit schedule. Aside from the first week of feeling drained during any WOD over 5-7 mins. My energy levels are pretty much back to normal and I feel great.
My question is (sorry for the long build up, I like to talk)... Is my non-hunger due to my body tapping into my body fat reserves (I have a little extra weight around my abdominals) or is it an adjustment and my body is down regulated thermogenically?
I could probably guess that it's my body burning the excess body fat, but I tend to second guess these things and I would just like some reassurance or someone to point me in the right direction.
Thanks for you help in advance and sorry for the drawn out post.
