I haven't read up on it enough yet. The theory is the juicing breaks down the cellular walls of the plants and releases a lot of enzymes and anti-oxidants into the juice that can then be digested by the body, and if there is enough quantity over enough days, the body will be detoxified. Otherwise, when eaten solid, most of the valuable stuff passes through the body's system without absorbsion.

I think it is combined with adding flax seed and such to some of the juices, so as to get the B vitamins. And one is supposed to eat a dinner high in vegetables and lean protein.

The purpose is to flush the toxins out of the liver so as to increase liver function. One theory is the reason why many women stop burning body fat, even with high cardio activity, is because too many toxins have accumulated in the liver, lymphatic system and emptied fat cells, and that many of the recent new toxins minic hormones, thus altering the way our body chemistry works.

It is something a person only does for the short-term. I just can't figure out how it is done while cycling, unless I wait for the dead of winter and there are three weeks of snow and howling wind. With cycling, I would not have sufficient calories to fuel my rides. I am not willing to cut back on my cycling.

If I were to try it in the dead of winter, when ironically the availability of fresh produce is at the lowest, I don't know if I could last 21 days. I imagine a lot of the juice concoctions taste horrible, and probably one is always hungry.

It is just an idea. Somebody out there must have tried it sometime and has an opinion.
