Looking for more fiber, metamucil?

I'm looking for more fiber in my diet so it can regulate my digestive system and speed up my metabolism. Does fiber do these things? and is metamucil a good way to go when it comes to adding fiber to my diet?

no i wouldnt use metamucil its gross! i use fibersure. i am prty athletic and i am prty sure it helps me stay fit. i also have a GIANT metabalism. i put it in brownie mix, water, yougrt, prty much everything thats ovbious!
