Sorry for late reply. First, I would not avoid carbs. I would limit them, e.g. 150g on training days. The next question is when to consume them. For me, I would have them around the workout period, i.e. pre/intra/post. If you are eating protein/fat meals outside this window then you should be improving insulin sensitivity (this can be further enhanced by following a form of IF). The carbs around the workout are fuelling the session, aiding recovery, and lowering cortisol post-exercise. That said, if someone said to me 'I am desperate to drop body fat and I don't mind losing a few lbs of muscle along the way', I would say try low carb or even keto dieting and avoid any pre/intra/post workout carbs. It works but there is a price to pay. It's all about personal choice at the end of the day.
