Marijuana users are less likely to be obese, according to a new study that would seem to fly in the face of the legendary munchies that are almost synonymous with pot. Researchers were so surprised by the results that they examined a second sample, only to come up with the same findings. Ultimately, the researchers used two national surveys involving a total of 50,000 people to come up with their results, LiveScience reports.
The study found that while 22% to 25% of non-tokers were obese, just 16% to 17% of those who self-reported using cannabis were obese. And obesity became less common the more frequently cannabis was used: Of those who used marijuana at least three days a week, just 14% were obese. The reason for the link is not clear. “I would be surprised that cannabis use is associated with a higher rate of physical activity, but this cannot be ruled out,” says one researcher, who notes that despite the results, marijuana use is not recommended as a weight-loss aid.
