gained a lot of weight after cleanse

Hello,
This is just a small warning for some of you who are on the cleanse. I finished a 12 day cleanse about 3 months ago. It was great! I felt great and eliminated a LOT of toxins! I lost about 10 pounds. Now, 3 months later I have gained 22 pounds! I am well above the weight I have maintained for 5 years. I stopped eating red meat after my fast, and did not change any other aspect of my diet or excersise after the fast. I do not eat junk foods, and I work out about 2-3 times a week. The weight gain concerned me so much that I decided to go to a homeopathic doctor. He informed me that the weight gain was probably due to the fast (he does promote healthy fasting). He said that extended periods of fasting causes your metabolism to screech to a halt, and can have lasting effects, as well as weaken the cell walls in your body. I am burning much less calories while I am at rest now then before the fast, and get tired much faster while excercising.
I am not trying to discourage anyone from fasting or keeping a healthy body.. but REALLY enourage EVERYONE to visit a doctor or health practitioner BEFORE starting any type of fast! Good luck and blessings to ALL!
