I'm going into my 3rd week of eating the brancrisp crackers I ordered. They look JUST like particle board. But they do taste better. I like them well enough spread with hummus or light cream cheese (mixed with dried ranch dressing powder, 'cause that's how I roll). I eat two at a time with a large glass of water because I don't want them setting up like concrete in my inners.
I'm down about 4 pounds so far. I find that they really do help with my "mindless eating" instinct that shoots me down when I get home from work. Perhaps a fullbar would work as well, perhaps not.
Each cracker has 12 calories and 5 grams of fiber, for a total of 14 calories and 10 grams of fiber, plus whatever the toppings I add. Hummus is what I usually use, so let's call it about 70 calories and 1 gram of fiber, just for fun. The crackers were 30 packs of ten for 65$, or about 22 cents each. I make my own hummus on the cheap, so let's call that around 50 cents per two cracker serving (I think it's less than that, though). So I'm spending less than a dollar per snack, and eating less than 100 calories. Total grams of fiber, 11.
Fullbars, in comparison, can be had at the website with a buy two months get one free deal for a total of $1.22 per bar. If you go with the two week deal then you're paying $2.50 per bar. And of course, there are reports in this thread on how they can be found cheaper. Depending on the flavor, they have between 150 to 180 calories. Per bar, depending on the flavor, they have 4 to 5 grams of fiber.
I have a gut (gut. Get it? Oh... nevermind) that this whole "eat fiber to curb hunger" thing might really work. It makes sense to me that it would. And even if not, well, eating more fiber does have other benefits that I feel no need to go into graphic details on.
In summary: If you are cheap or poor like me, and don't really like the idea of eating a sweetened bar for snack everyday, you might want to look into the getting some
Bran Crisp Crackers instead. If you have a low tolerance of particle board looking foods you might be better off with the full bars.
