Less water will make you lose less weight since the remainders of the fats (after burning) will leave your body through urination. If there's not enough water in your body, the body will stop burning fat to avoid producing these toxins. You will feel tired and weak and you won't lose as much weight. If you have enough water in your body, you won't feel tired or weak because your body can burn the fats. There's no harm in drinking extra water anyway (unless you drink like 7 liters then it's dangerous). I am currently drinking around 4 liters per day.
Remember not to drink your water in one go because it will directly get out without properly going through your system! You should spread it evenly throughout the day. Before going to bed you should urinate AND drink two glasses of water so your body can properly use the fats for its energy while you sleep.
