I don't believe in forced detox. I believe that you wash out a whole lot of good and needed with the bad. I feel that anytime I go against what my body was designed to do, I feel I am messing with nature. My body was designed to run on proteins, carbs and other essential things, all in balance. For many years I just ate way to much of all that balance and gained a lot of weight. I was designed with teeth to chew with so having nothing but liquid is messing with nature to me. I do consume a lot of liquids but not exclusively. I do not carry around 55 gallon jugs of water to cross the street. Our ancestors used to work in the fields all day and not consume anymore water then we do between breakfast and mid-morning and they worked hard and long and where we sit on chairs most of the day and almost never work up any sweat. That is what clears a lot of the toxins out of our bodies. Instead, we are constantly sipping liquids that we are only expelling through our kidneys and not flushing out the rest of the body. Where does all that water go, well, in my opinion, the body stores it. It also creates additional cells to store it in and then we wonder how come I'm not eating anything and still gaining weight. To me, that might be the answer. To many liquids.
Anyway, sorry for the ramble, and I am not being judgmental concerned everyone individual decisions on what to do to stay healthy. Seriously, I don't want that responsibility, however, I do have my own theory's.
BTW, If anyone wants to really flush out their system, I recommend scheduling a Colonoscopy. Believe me that every bad thing you ever put in your body comes out including that candy bar you ate when you were 12. PLUS, you will lose anywhere between 5 to 8 pounds in one day. I like to call it "time management".
