I have to concur with KouKou on this one. Chefs are not nutritionists or doctors, so you should take the advice of your personal healthcare professional over anything posted here.
At our shop we make lots of smoothies and juices and use a lot of organics in our pops. Seeing that, we get customers with every imaginable food agenda wanting this that and the other and for the most part we try to accommodate them. What frustrates me are the stick thin women who come in to get juices for their "cleanses." Don't get me wrong, I love green juices and drink them frequently myself.
What so many people who do these "cleanses" forget are two important nutritional facts:
1-if you are a generally healthy person, your liver and kidneys do a very good job of cleansing your system of toxins. If you are having elimination problems-eat more fiber. Oats and apples work very well.
2-if you do not ingest some protein everyday, your body thinks you are starving and goes into famine mode which slows your metabolism and uses its own protein. What is your body's protein? Muscle tissue! Hence, people who report losing weight during cleanses and fasts do not lose by metabolizing fat, they are efficiently burning up their own muscle mass!
So please be careful with radical diets and follow the directions of a licensed medical practitioner. There's a lot of crazy info out there that many people swear by.
