Yes, it's helped me quite a bit with energy levels, which seemed to fluctuate a lot before. I'm still struggling with how exactly to stay on it. It seems if I go over a certain threshold of carbs that I have a huge drop in energy.. Though I haven't done the whole pee strip whatever thing to find out what my tolerance is.
With better energy levels comes better concentration and hopefully I can control my ADHD symptoms. Diet is a big deal for sure!
