Fasting would be a form of prayer, God sees the heart as well as your motives,prayer is simply just talking with god weather it's a thought or a spoken word,,Their's no such thing as being in the wrong place to pray ..

Fasting can be beneficial and those on a  reduced diet will live longer. Prayer is talking to yourself and has no benefit to you or anyone else.

Fasting is to go without food, but fasting and praying is to take your mind off your belly and feed your mind with the words of God , For it is written," Men shall not live by bread alone, but by every words proceed out of the mouth of GOD.

Oxford English Dictionary: Definition of Fast, ' to go without food '.

I hope your God appreciates your prayers. I don't pray, but if you gain benefit from praying so much the better.
