How much does water help increase your weight loss?

I drink about 2 litres of water. (Plus few cups of tea and glass or 2 of juice).

I do feel better when drinking plenty each day

Water does nothing to speed up or help weight loss beyond feeling full if you drink a lot and the extra exercise of running to the bathroom. You need enough fluid for your urine to be pale yellow, beyond that you're just wasting time. Water doesn't flush out fat or toxins or any of the other magical things I've heard it can do. It hydrates your body and when that is achieved you pee it out.

This as well.. besides keeping your body hydrated you won't lose weight just because you drink water.

I drink around 8-12 glass of water during the day. It is one of the reasons I am losing weight; along with exercise and eating at deficit.

You're losing weight mostly because you eat at a deficit, a bit because you exercise and not at all because you drink 8-12 glasses of water.

Proper hydration is important, but as far as making you lose weight that's not unless you replace your calorie laden drinks with calorie free water and don't eat the calories somewhere else.

Water does remove waste from your body. That's it's purpose. However, drinking water alone is not going to make you lose weight. Your body needs to be hydrated to function properly. Drinking enough water to stay properly hydrated will give you a feeling of well being, help avoid tiredness, headaches and other woes from being dehydrated. There is no magic number as everyone is different. The best way to to increase weight loss is eating clean, exercising regularly, getting enough sleep and avoiding stress as much as possible. There is no diet or magic pill that will increase weight loss without truly changing your lifestyle.

The reason you lose weight by drinking water is usually because you end up cutting out soda and other drinks out of your diet that contain calories (because you're not that thirsty after you drink all that water), creating a deficit. It also helps with your bowel movements to make them more frequent, meaning that your body becomes more efficient at removing the waste and preventing a build-up of it (we can hold around 7lbs of food waste in our bodies if we don't take care of that).

Because you end up putting less sugar and fats into your body from drinks, you have more room in your calorie goal for proper foods that contain more nutrients and vitamins, which can boost your overall health and make your body perform more efficiently.

Water itself does little to make your weight go, it's the circumstances surrounding the plenty drinking of water that usually does it.

While I agree that water in and of itself doesn't make you lose weight, often we mistake thirst for hunger. Being properly hydrated can keep this from happening. I'm trying to drink a glass of water if I feel hungry but know that I really shouldn't be (I've eaten recently for example).

I haven't found that water helps me with weight loss, but it does help with feeling more energized. I drink on average 100-125 oz of water a day (3.5 Liters), and if I do not I definitely feel a difference. It also helps with hunger pains a tremendous amount. I will drink at least 8 oz before each meal, and it helps me to not over-eat.
