Each daily serving of sugar-sweetened beverages was associated with a weight gain of 1.0 pounds over 4 years according to a study by Harvard researchers. Subjects

Subjects: 120,877 U.S. women and men

The findings are based on data from three large, long-term government-funded trials looking at diet, lifestyle and health in adults: the Nurses’ Health Study, which has tracked 121,701 women since 1976; the Nurses’ Health Study II, which has followed 116,686 women since 1989; and the Health Professionals Follow-up Study, which includes 51,529 men enrolled in 1986.

The new analysis involves 20 years of data on 120,877 men and women from these three cohorts. Researchers tracked changes in participants’ eating and lifestyle habits—and weight—every four years.

 

Average Weight Gain

Average weight gain over 4 years: 3.4 lbs or 2.4%

Comments from Dr. Dariush Mozaffarian

“For diet, conventional wisdom often recommends ‘everything in moderation,’ with a focus only on total calories consumed,” says Dr. Dariush Mozaffarian, an associate professor of medicine and epidemiology at Harvard Medical School and Brigham and Women’s Hospital, and lead author of the study.

“Our results demonstrate that the quality of the diet — the types of food and beverages that one consumes — is strongly linked to weight gain.”

“Small dietary and other lifestyle changes can together make a big difference — for bad or good,” says Mozaffarian.

“That makes it very easy to gradually gain weight unintentionally, but also means that a little bit of attention to a handful of dietary and other lifestyle changes can prevent this.”

 

Study’s Limitations

Study’s Limitations: self-reported portion size, and were white, educated adults

The study limitations included that it relied on self-reported portion size and used different serving sizes between foods.
