To answer your question about the lemonade cleanse.
I am no expert and I don't want to give you advice. It is different for each person but I can speak for myself.
I have done some study of the body and have learned that it is very intelligent and it knows exactly what it needs and tries to tell us if we listen. What I have learned about the body has amazed me.
If you decide to try the lemonade cleanse then listen to what your body says and trust that.
I have done the lemonade cleanse several times now and I think the most important thing about it is how you end the cleanse.
To answer your question, Does the lemonade cleanse depleate your system? I think there may be two different modes. The beginning of the cleanse is when your body takes the time and energy to do important housecleaning and repairs. After a time, which is different for each of us, the body goes into starvation mode and this is not good. Your body will tell you when it needs food and your system is getting depleated.
My body has been telling me for years that I was eating too much at each meal.
