据外媒报道，《家庭医学年报》（Annals of Family Medicine）刊登一项最新研究指出，饮水量不足可能导致肥胖。
美国密西根大学研究员分析9528名年龄介于18至64岁成年人的饮食习惯、喝水量，以及透过尿液浓度测量身体水化水准。
结果显示，饮水量不足的人身体质量指数（BMI）较饮水充足的人高。
研究人员表示，虽然身体水化水准与体重之间的关联不明显，但维持水分充足应有助减轻体重，因为身体通常可以解释饥饿和口渴的感觉。研究人员建议女性每天摄取2.7升，男性3.7升的水。

Researchers are learning whether a simple part of our diets might be linked to a healthier weight -- and it has nothing to do with carbs, fat or protein.
The potential secret weapon? Water.
People who are obese and have a higher body mass index （BMI） are more likely to be inadequately hydrated and vice versa, suggests new research from the University of Michigan published in Annals of Family Medicine.
“The link between hydration and weight is not clear. Our study further explains this relationship on a population level using an objective measure of hydration,” says lead author Tammy Chang, M.D., MPH, MS, an assistant professor in the Department of Family Medicine at the U-M Medical School.
Chang and colleagues looked at a nationally representative sample of 9,528 adults from the Centers for Disease Control and Prevention's National Health and Nutrition Examination Survey （NHANES）。 Roughly a third of the adults, who spanned ages 18 to 64, were inadequately hydrated.
