In a sentence, "Participants that watched sports every day were at higher risk of obesity [odds ratio = 1.39, 95% CI, 1.15, 1.68) after adjustment for age, sex, smoking, alcohol, physical activity, total TV time, disability, and self-rated health."
Based on what they're controlling for, and assuming that the conclusions hold, my guess would be that watching sports on TV is also associated with increased snacking.
