Day 3 of a ketogenic diet: The biggest change is the constant low energy, but mainly because I'm not consuming as much fat as I should (Hitting only 100g). My glycogen addicted brain is having withdrawals. Symptoms feel like a low fever, as well as fatigue and not feeling full after meals. After a few days, I should be feeling much better. Current goal is to lose .8 lbs/week for the next 4 weeks. I'll decide whether or not to stay keto after this experiment. Definitely missing carbs..
