I've been fasting along the 16/8 model by and large for the past few years. I usually take some MCT and cream or butter in my morning coffee. This all works fine. But it seems to me that while I have no trouble being in a fasted state for 16 or so hours, my body NEEDS carbs in the afternoon. I generally try not to do this, but my concentration really suffers. What is going on? Should I just eat the carbs and not worry about this? Why can't I maintain brain energy throughout the day? In the past, when I've gone ultra-low carb with lots of fats, after a few weeks I begin to suffer. My body just does not seem to like it. Any thoughts on this?

I'm giving keto and intermittent fasting a try and loving the results as well! I haven't had any concentration problems or felt as if I needed carbs for any reason.( I'm still cycling in some higher carb days with a starchy veggie like sweet potatoes once or twice a week so maybe that's why.) Are you doing the 16/8 fast every day or just a few days a week? I only fast 4 days a week and keep it keto the rest of the time. The metabolism is a moving target and some of the backlash you're experiencing may be from staying too low on carbs for too long.
