Madhuri, this is not water fasting. What you describe is closer to dieting.
Water fasting means nothing else other than water, also you'd better not spend energy in the gym if you drink only water and do not eat.
Best,

Agree with DL, also calcium by itself is not good. Get Dr. Dean's book, "Miracle Magnesium" and read it thoroughly, especially if you are a woman. Magnesium is very necessary for calcium to digest. CA and MG are brothers, next to each other on the periodic table, they work together.

Another thing is that partial eating leads to starvation. I believe we have talked about this before.

If you want to fast, fast with nothing but water. You will be amazed how your body and mind will heal.
