It's ridiculously simple advice. Advice that has been a mainstay of weight loss tips articles for years now, but there is more scientific validity now to back up the common sense advice of drinking water before you eat (2 glasses in this case).
Let's take a look at the study.
Lead author Brenda Davy, an associate professor at Virginia Tech, found that middle-aged and older adults who drank two cups of water before each meal consumed fewer calories and lost more weight, than those who skipped drinking water.
For 12 weeks, both groups followed a calorie-reduced low fat diet, but one group was instructed to drink 2 glasses of water before breakfast, lunch and dinner.
- The diet-only group lost 11lbs.
- The diet + 2 glasses of water group lost 15.5lbs.
We're not saying drink more water and the body fat will melt away, but for people who are trying to lose weight and trying to follow a low-cal diet, it's something they can do as part of that. Source
Mindful that keeping weight at bay long-term is the real challenge for most people, researchers followed participants for a full year to see if they would relapse. Encouragingly enough, those who continued the water protocol not only kept the weight off, but actually lost a little more (1.5 lbs on average).
Caveats and other interesting bits
- Davy suggests that downing water may only work if you are middle-aged, as older individuals' systems take longer for the water to empty from the stomach.
- It should go without saying, but it's pretty important that calories are under control and that a healthy diet is (and always will be) the first strategy for fat loss. Sculling a couple of glasses of water before crushing cheese fries and donuts won't work.
- When you are drinking water, you are not drinking something else (pop, juice, etc.). This is no doubt a big reason as to why it's so effective.
Considering water costs almost nothing (assuming you aren't buying the stuff in fancy bottles), and appears to be more effective than most supplements (that cost money, lots of it in some cases) - this might be a strategy worth trying.
