In people with a high genetic risk for obesity, getting a lot of sugar from sugar-sweetened drinks may amplify the genetic effects on obesity.
The study and two others looked at the effects on weight gain of sugary drinks — including sodas, fruit punches, lemonades, or other fruit drinks. The new research should inspire people to give up sugary drinks or consider them an occasional treat. It gives very clear evidence that drinking sweetened beverages even in modest amounts clearly results in increased weight and excess weight.
In a statement, the American Beverage Association countered: “We know, and science supports, that obesity is not uniquely caused by any single food or beverage.”
Sugary Drinks and Weight Gain in Teens
In another study, researchers split 224 overweight or obese teens who regularly drank sugary drinks into two groups.
One group was encouraged to drink fewer sugary drinks during a one-year program. They were followed for another year without a formal program.
The other group was not encouraged to have fewer sugary drinks.
