Gaining weight on a pure water fast?!

I've already posted on here before concerning losing weight on Water Fasting but i feel this needed a separate post. 2 days ago i was happily losing weight, ranging from 0.5-3lbs a day. All of a sudden i gained 1lb yesterday and today i gained another pound! I really do think i've broken my body >.< I have no idea how i gained weight when all i've consumed is water! I'm on my 9th day of water fasting, 18 years old, 5ft 6inch. 2 days ago i did weigh 18st 12lbs now i'm back to 19st. How is this happening?! I'm not discouraged though, i'm still going to continue Water Fasting until i feel true hunger. Has this happened to anyone besides me? Any suggestions would help! Tweet
