Re: heart and liver damage
all of that is true, BUT...
1. you are getting sugars from both the lemon and the maple syrup so you are getting a constant supply of energy...that means your glycogen stores are not really being used up..if they were you would pass out so that your body could divert as much as possible to your brain and eyes.
2. if you fast for a very long time your body will start to feed on itself, but its going to start with your muscles then move onto your organs..if you get to the point where your body is feeding on your organs then your going to be so thin and weak becuase your muscles have wasted away that you would notice something is wrong..unless of course you have a body image disorder, but thats another issue.

The Master Cleanse is supplying you with all the nutrients AND calories you need.
people who say that fasting is bad for you have usually never been on a fast and/or have not takent he time to really research it. they just assume people are starving themselves. a proper fast will keep you hydrated (this is way more important than food) and it should give you nutrients.
there are many types of fasts and many different reasons to do them...some good some bad. you cant generalize becuase everyone is different
