Which basically means if you eat a lot of food that is either 99% water, or 99% indigestible wood fibers you'll lose weight.

So the ideal food is something like cotton, or sawdust.

Phooey.

Personally, I don't think pure 'bulk' is enough to stave off hunger. Hunger is your body's way of reacting to low fuel levels.

Pack your intestines with mulch all day long if you want. You'll still be hungry.
