To clear your bowels, that is the complete opposite of what you should do. Filling yourself with stodgey food and getting little to no digestive fibre will have the opposite effect of what they're claiming.

I went away on holiday this year I filled myself up with Na'an bread, Garlic Bread, Pizza, pasta and a shit load of meat... basically no fibre.

I can't remember a single week where I went away from my eating habits so much and ate so little fibre.

When I got home I was 10 pounds heavier. two days of being back home and eating my normal diet of proteins, veg and whole grains, 7 pounds of it was gone. (down the toliet!)

If you really want to drop weight by shitting it out, then start eating a tonne of flaxseed or linseed.

In it's whole form, your stomach can't break down the shell... so it passes right through you taking any crap in your digestive track with it.

It's essentially 100% insoluble fibre, if you get it milled there's a lot of omega 3 in it... but you don't get the same effect in terms of flushing crap out.

But yeah... it's the polar opposite of white bread etc.
