I hit a WALL this past Summer with the 21 day fix/portion fix style eating plan. My carb cravings & anxiety were out of control, I was tired all the time and my weight had started creeping UP. I was just sick of it and decided to try something completely different! Transitioning to a LCHF (low carb high fat) ketogenic diet and added exogenous ketones has made me feel like a NEW person!!
