A study presented here at Obesity 2012: The Obesity Society 30th Annual Scientific Meeting widened the sugary-beverage/obesity link to include sports drinks. Currently, sales of sports drinks are rising as sales of sodas are tapering off.Only more Calories in than out causes weight gain.
Data on nearly 11,000 offspring of participants in the Nurses' Health Study II, aged 9 to 15 years, were tracked over time by Alison Field, MD, associate professor of pediatrics at Harvard Medical School in Boston, Massachusetts, and colleagues.
At the end of each 2-year interval of the study, the teens had gained almost 2.0 pounds for each can of soda they drank every day. If they drank 2 sodas a day, they gained 4.0 pounds over each 2-year interval.
Importantly, this study revealed the previously unknown consequence of drinking sports drinks; the teens gained an average of 3.5 pounds for every sports drink consumed per day.
"Sports drinks have an even stronger relationship than sugared sodas with weight gain," Dr. Field told Medscape Medical News. "I was surprised by that. I would have expected the weight gain to be comparable."
Incidentally, this article presented no data as to what was gained as weight, i.e., fat, muscle, both.
Still would have been a crap study even if they told us.
