Fasting should not be starving!!

I have been doing fasting for a long time. I started this as a faith in my goddess lakshmi. Before marriage I used to fast only few occassions like janamasthmi and navratri. Other than this i n ever gave importance to weekly fasting which many hindu people do. I felt the need for this after 3 years of marriage when we started facing financial problems in our relationship. I started doing fasts on every friday of each week. I started this as I thought this would help me out in solving many of my problems. Often one starts fasting for the sake of loosing weight. But this is not a correct step. As fasting can bring down a loss in the muscles but it causes serious problems with the immunity system of body. This is because while fasting one lacks the important nutrients in his body and eat few things which lack the energy. Fasting is done for many reasons also like ritual one. One starts fasting on few days like monday or friday etc. That is fine. If it is done a day or two in a week then that is fine as fasting is considered good for body also if it is done rarely. While fasting stay away from oily, coffeine etc. Take water and fruits as this cleanses the body and flushes away the toxins from the body. So do fasting but wisely.
