Does god want us to fast?
In food and water there is micro-organisms. In a clean glass of water there is 10 million alone. For this reason God prefers you fast and take a break from food and drink.

You don't have to go as long as Jesus (On the verge of death Matthew 4:2; "After fasting forty days and forty nights, he was hungry") but having a day or two away from food and drink will strengthen your prayers and closeness towards God. You will also be consuming less living organisms per year if you fast when you can.
Set a certain day every couple of months at first, like a Saturday. Then you should get used to it when increasing the frequency.
