felk - why would you need or want a fast metabolism unless you just wanted to stuff yourself with unnecessary amounts of food. in evolutionary terms a fast metabolism would be a very bad survival trait. it would mean you had to eat far more than those around you just to survive. you get me?
moreover studies done around the world looking at average lifespans have found that one of the common traits to the long lived have been that they eat far less than the typical western diet. small meals based around fuit, vegetables, nuts, seeds, and small amounts of animal flesh.
like if you sit down and eat a steak with some veg and potatoes etc, you'll probably only absorb a very small fraction of those nutrients and either sh*t out the rest or your body may store it as fat. so why eat it in the first place.
oni - i agree completely and in the lead up to this juice fast i ate only fruit and veg for that exact reason. the high fibre types, like oranges with the pith left on etc. that said even though i'm only drinking liquids im still producing quite a large amount of solid waste.
diet wise i also agree, my basic rule is if its poisonous raw then dont eat it cooked either. which puts potato, wheat and corn totally off my plate.
