Please Alu - do research on your diet. Yes, we all need water, but not just water - it would trick your body to think it is in starvation mode and you will end up gaining BIG TIME when you do have food. Eating 6 SMALL meals a day will actually help you lose MORE weight FASTER, Starches, sugar, dairy products are the culpret. Eat more fruits and veggies (fresh) PLEASE do not JUST drink water. Good luck with it!
