I was on atkins diet about 4 or 5 months ago and lost about 15lbs I started having problems while I was on it and decided to quit thats was about 4 or 5 months ago. I have not gained any weight back but i have been having heart problems, anemia, bones are weak from not enough calcium. The doctors are not sure what all is wrong with me yet because I have had so many test and all the results are not back yet. but before this diet I never had any health problems and there is no heart problems that run in my family. I have to take about 12 pills a day. I just thought I would let you guys know what can happen being on a diet like this, it is very very dangerous so, please be careful.
