"Our results indicate that when combined with a hypocaloric diet, consuming 500 ml [ approximately 16 fl oz] of water prior to each of the three main daily meals (1.5 [ liters per day ]) leads to [ approximately 4.4 lbs ] greater weight loss over 12 weeks [ 3 months ] as compared to a hypocaloric diet alone, among middle-aged and older adults," the authors of new study conclude.
“This difference was attributed to a 44% greater rate of weight loss among water group participants compared to nonwater participants over the 12-week [ 3-month ] period,” they continued.Reduced Calorie Intake
Water reduces calorie intake, although it is not clear how long this lasts
“This effect may be due in part to an acute reduction in meal [ energy intake ] following water ingestion, which we observed at the baseline laboratory test meal studies”
“A reduction in meal [ energy intake ] following water consumption is accompanied by increased sensations of fullness, which may facilitate a lower meal [ energy intake ] following water ingestion.
“However, it is not clear from our findings how long this effect is sustained, as we did not observe significant differences between meal conditions after the 12-week weight loss intervention.”
Subjects: 18 men, 30 women, 55-75 years old, BMI 25-40
The study involved 18 men and 30 women, ages 55–75 years-old, who were overweight or obese (BMI 25 to 40).
Drinking 2 cups of water before meals increases weight loss when combined with a diet
“We conclude that for overweight or obese middle-aged and older adults, consuming [ approximately ] 2 cups of water prior to each of the three main daily meals may increase weight loss when combined with a hypocaloric diet, as compared to a hypocaloric diet alone,” the authors concluded.

In an average human, basic life processes require energy to be supplied at a steady rate of 100 W ? What daily energy intake, in Calories, is required to maintain these basic processes? This is the minimum daily caloric intake needed to avoid starvation.

Generally, 800 calories per day is the minimum that want someone to eat when trying to lose weight on a very-low calorie diet.
Some go as low as 500 calories, but it's usually not recommended.
