Water cleanses externally. In the New Testament this process is called 'baptism'.
Fasting cleanses the inside.
Biblical fasts do not eliminate all foods, but restrict the diet to one or a few items for the length of the fast.
For instance, not eating any meat or eating only bread are fasts.
One of the first God mandated fasts is Passover, you shall not eat anything fermented (leaven) for 7 days.
