of water daily may help you lower your total calorie consumption, it's not a guaranteed method. However, if you do end up reducing calories because of drinking more water, you are likely to post results similar to those in Davy's study, which indicate that you may lose just over 1 lb. per week.
To lose 20 pounds (9 kg) in two weeks, you will need to lose a little under 1.5 lbs (675 g) every day. That means burning a little over 5,000 calories more than you consume each day. Yep, a very, very tall order.
Water makes up 60% of your body weight, and it's one of the first things you lose. Weight decreases as a change in muscle, fat and water. Fat mass doesn't change quickly, but you can lose as much as five pounds of water in a day. The average 24-hour urine loss is about 1.8-4.4 pounds because water is heavy.
Like other types of fasting, water fasting can help you lose weight. However, it comes with plenty of health risks.

For example, going on a low carb diet, or cutting your carbs way back, triggers the loss of glycogen and the water stored with it, and if extreme, can also be dehydrating. Just two cups (16 oz) of water weigh one pound, so shedding fluid fast can result in weighing a lot less on the scale.
Reduce carbohydrate intake
When we eat carbs, the energy that we do not use right away is stored as glycogen molecules. Each gram (g) of glycogen comes with 3 g of water attached. Cutting down on carbs is a quick way to use up the glycogen stores, which means that the water weight will also be reduced.

The 72-h fasting induced significant decreases in glucose level, body weight, and an increase of ketone bodies that confirmed successful fasting of the volunteers. In addition, the median of BDI-2 increased significantly (4 vs. 7, p = 0.006).
Studies of older adults have shown that drinking water before each meal may increase weight loss by 2 kg (4.4 lbs) over a 12-week period ( 4 , 11 ). In one study, middle-aged overweight and obese participants who drank water before each meal lost 44% more weight, compared to a group that did not drink more water ( 4 ).
But drinking more water should be only one small part of your wellness journey. "Drinking water is not going to have a huge weight loss effect, and without calorie restriction and/or exercise, just drinking water is not likely to lead to significant weight loss," Jampolis says.
Aim for 64 ounces a day (it's a good goal for all of us, even if specific needs vary) and of course, skip the soda.
