I went on this diet in 2010. It was the best thing that ever happened to me! I followed it so strictly. I was able to go from 200lbs to 140 in 4.5 months! Ever since then I have maintained my weight and have not gained more than 10 pounds back but I quickly get my butt in the gym and work that off if I fluctuate. To this day I use this diet in modification for maintenance. If i ever want to lose weight I go back on it for a couple of weeks adding small things like peanut butter..hand full of fruit so I don't go completely back into ketosis un-watched.
A lot of my hair did fall out but it grew back and I have not had any issues. This diet is really hard but if you want it you can do it and it WILL work! Evie and Sophia were great and supportive and answered all of my questions any time I called about a certain food.
Because of this program I have maintained my weight and felt amazing for the past 5 years.
