The average American does not drink enough water, which could be a factor in the national obesity epidemic. “About 33% of the people in the study weren’t adequately hydrated. What’s more, the researchers found a link between dehydration and overweight. People who weren’t hydrated enough had higher BMIs than those who were. There may be all kinds of explanations for these findings. People with obesity need more water than people who have smaller bodies, making the hydration threshold potentially harder to reach. But some research suggests that water can play a role in weight control, showing that when overweight people drink water before a meal, they eat fewer calories than if they eat it without water.” You can tell if you’re hydrated by looking at the color of your urine – if it’s dark, you may be dehydrated. This study only suggests a correlation and more research needs to be done.
