I had the same experience. I cut off all noodles/pastas and breads, and ate no pastries/sweets/chocolates. I went from lifting a few times a week for three months to once a week and my brain could not have a rational thought. I felt like my sugar levels were down all the time some how, so even after eating meats, eggs, vegetables, and dressings, my body would feel light and I couldn't get full. I couldn't work on my computer a lot and basically was on autopilot. It was kind of bizarre because I was eating 4-6 eggs a day and my body started feeling really weird. I think all the protein was messing with my body when it was trying to break it down.
