Well my keto experience was not all that unusual for a female. I was pretty strict for 6 days, entering ketosis tuesday night to wednesday morning. The blinding headaches, nausea weakness and dizziness I put up with for 6 weeks (stupid me) and I missed a lot of work thinking this was ultimately for my well being. By 6 weeks I had lost a lot of weight, but too much of that was muscle. Almost certainly this was because I could not eat enough of the foods to maintain LBM. I threw a lot of my meals up again. When I came off the diet I had uncontrollable urges to eat lots of carbs AND fat, and I had previously had no trouble maintaining a low fat lifestyle. Worse than that was the carbs I craved were absolute crap carbs. Needless to say I gained back all the weight I lost and then some. It took me around 6 months for things to stabilize so I could stick to a healthy diet. I am over 40 years old and I have never had any eating disorders before so I found this experience very unpleasant. Bottom line is the diet worked well for fat and muscle loss. I felt very ill most of the time and suffered serious post diet rebound.
