If you didn’t already know, sugary drinks cause weight gain

This comes as no surprise but avoiding sugar drink limits weight gain. From the New York Times:

In one of the new trials, researchers at Boston Children’s Hospital randomly assigned 224 overweight or obese teenagers to receive home deliveries of bottled water and diet drinks for one year. The children also were regularly encouraged to avoid sugary drinks. Those who received the shipments gained only 3.5 pounds on average during that year, while a comparison group of similar teenagers gained 7.7 pounds. The differences between the groups evaporated after the deliveries stopped.

In the second trial, researchers at VU University Amsterdam randomly assigned 641 normal-weight schoolchildren ages 4 to 11 to drink eight ounces of a 104-calorie sugar-sweetened or noncaloric sugar-free fruit-flavored drink every day from identical cans. Over 18 months, children in the sugar-free group gained 13.9 pounds on average, while those drinking the sugar-added version gained 16.2 pounds.
