Any time is the best for consuming water, especially when we speak about such situations when you need to lose your weight. Water launches our metabolism, hence it's getting much easier to lose weight when we're drinking enough water. In my opinion, water should be consumed by everybody, without exceptions. If you want to drink some fizzy drinks you would better drink a bottle of water. It helps you to get rid of the thirst and helps you not to get dehydratated. Of course, some people forget about this rule and always neglect it. So, it's their problem and you shouldn't follow such people actually.

People those who likes to drink water for weight loss, then the right time is morning after the breakfast and noon time one hour before your lunch. Please avoid to drink water in the night time, It will disturbed your sleep and also gives more work to kidney. So please drink plenty of water in the morning and noon time. 2 - 3.5 liter is enough to reduce the body weight.
