Depends.: How frequently would you like to urinate? 2L is generally adequate intake. Body requires 1/2 ml/kg/hr to maintain waste excretion. For 70 Kg person this is 35 ml/hr (840 ml/day). Body also has fluid losses in stool, sweat and breathing which are about 300 ml/day. Therefore 1200 ml intake is absolute minimum for normal person. This all changes if workload, heat or losses go up. 2L sufficient.

What helps women lise belly fat(pooch) quickly?

Dr. Francine Mosley

Healthy takes time!: A belly doesn't develop a "pooch" overnight, and it won't go away overnight. If you have a pooch, for whatever reason, sit- or stand-up straight, suck-in your stomach to strengthen your belly muscles, trade water for soda pop and make good food choices. Your belly will look better.
