Researchers Say This Is the Magic Amount of Water to Drink for Weight Loss

You've probably heard before that water can help you lose weight, right? But can it really? That's what researchers from Nutrition Sciences at the Berlin School of Public Health, Charite University Hospital wanted to know, so they reviewed 11 related studies to find out.

Of the 11, they found three supporting the idea that water helped in weight loss. One found that people who drank two cups of water before eating a meal lost more weight—four pounds—than people who didn't. And the results of another showed that people who drank at least one liter per day—a little less than the recommended eight glasses—lost more weight than those who didn't. Funny thing, though: They're really not sure why.

One theory is that water helps keep hunger at bay, but there could also be another possibility: Water-induced thermogenesis, a process where drinking water makes you more energetic and, therefore, burn more calories overall.

Of course, the researchers also say that there are still more studies that need to be done in order to find a firm link between water and weight loss. 

Still, there's no arguing that it's important to drink plenty of water: It flushes out toxins, helps carry nutrients to your cells, and supports every system in your body. And not getting enough water can lead to dehydration, which stresses out your organs and can lead to headaches, dizziness, fainting, and exhaustion. So drink up!
