The first time I was introduced to Benefiber was years ago. My Mother used it in her morning coffee, and while visiting me we had to go pick some up, because she just couldn't be without it. I didn't really understand her obsession with it and when I tried it in my coffee like she suggested, I felt like it left a residue and didn't really like a slight aftertaste. Well, I was young and stupid, because now I swear by Benefiber too! Some day I'll learn not to question my Mother...
Benefiber is a fiber supplement that contains 0grams Sugar/4grams Carbs/3grams soluble Fiber, so on the Belly Fat Cure you can count it as an S/C Value of 0/0 if you have it by itself. There are some varities of Benefiber that have slightly different Suppliment Facts, so be sure and check the back of your bottle. For example, Benefiber with Calicium is 6grams Carbs and has different serving sizes and some of the chewables have sugar.
Benefiber is made from Wheat Dextrin and is meant to be taken in a liquid. I add it to my morning coffee every day. I feel like it doesn't add any taste or texture, unlike that first time I tried it. Jorge Cruise give it his Belly Fat Cure Seal of Approval in the book too. While you can use it up to three times a day, I typically just use it in the morning coffee. Maybe occasionally with a cup of tea at night if I feel like I had a low fiber day. Ideally I'd like to get all my fiber from my food with no need to supplement, but it is all a process.
I sometimes buy the generic store brand (Target has a good deal on their store brand) but recently broke down and bought the extra large bottle at Costco. Costco has a $4 off coupon this week for Benefiber. Amazon also has Benefiber for a good price too.
Jorge also recommends pysllium husks, but frankly I can't stand them. I had one glass full of the stuff and threw out the whole container. Benefiber, for me, is much more palatable. Here talks about the benefits of fiber and fiber supplements. I found his videos on bowel movements to be really helpful (and shocking!).
