>But people sometimes report experiencing negative side effects when they try to eat less sugar. Headaches, fatigue or mood changes, which are usually temporary, are among the symptoms. I did keto for a few months a few years ago, and I did experience this. They call it the "keto flu" because it apparently happens to most people when they first start the diet. It was unpleasant, but it didn't last long, and I felt _incredible_ for the rest of my time on the diet. I lost weight, had a six pack, and had more energy than ever. It's definitely hard (nothing replaces the texture of real bread), but I do wish more people would try it, just to see if it has the same benefits for them that I experienced.
