Oh I am so glad to see this post!!!!
I did the Fiber35 Diet back in May/June after seeing it on PBS. I bought 3 bottles of the shake mixes, the fiber supplement and the bars. And yes I was drinking the required GALLONS of water! I was up 3 times a night peeing, LOL!!!
After 2 weeks, I was so constipated that I had to go to my doctor - I had gained 9 pounds and NOT going to the bathroom but once every 3 days!!! I normally go once a day (too much information????)
Needless to say that my doctor was laughing her head off at me!!! She said that yes a high fiber diet is WONDEFFUL but you cannot go from 5 grams a day to 35 grams a day in ONE day, LOL!!! You really have to do it gradually or you will screw up your system.
She told me NOT to stop but to cut back a bit and gradually add more fiber weekly and NOT daily. She also prescribed GlycoLax to get me going, LOL.
After 6 weeks, I still had problems so I stopped. I started again this week and am going to follow the F-Factor Diet (as suggested by the Chicks) but will go gradually like my doctor suggested. I will keep you posted as to whether this works.
So far the only thing that has worked for me is walking 5 miles every day (6 days a week and no less) AND limiting myself to 20 pts. on WW. And for maintenance, I have to continue walking and not eat more more than the 20 pts. a day.
