Since when does a diet pill become a fiber pill that has nothing to do with dieting? if you go and read about products like glucomannan, you'll learn that it's suppose to be a diet pill. yet it mentions nothing about weight-loss and talks about everything else that it's good for.
Personally I like to get my fiber the old fashioned way by including bran or flax seed in my meals. I generally include flax seed in my morning breakfast shakes, which gives them a yummy nutty taste. Heck, I've even placed it over soy ice cream to give it some flavor. I'll skip the diet pills, thanks.
