I tried doing Keto and I was as sick as a dog for 2 weeks straight. I felt awful physically. Not to mention my anxiety was through the roof. I lost about 6 pounds real fast but then plateaued for about a month straight. Once I got off it and went back to just eating a low calorie diet I immediately felt better and started losing weight again. I was eating a lot of bacon and and eggs and nuts and seeds and chicken and steak while I was on it.
