An apple a day keeps the doctor away. Here’s a new health-related adage to consider: Regular consumption of marijuana keeps you thin and active.

According to researchers at Oregon Health and Science University, people who use marijuana more than five times per month have a lower body mass index (BMI) than people who do not marijuana.

The researchers concluded:

“Heavy users of cannabis had a lower mean BMI compared to that of never users, with a mean BMI being 26.7 kg/m in heavy users and 28.4 kg/m in never users.”

The study also suggested that people who consume marijuana on a regular basis are more physically activity than those that use it sporadically or not at all.

Of course, this is not the first time scientific studies have reached this conclusion:

A study published last year in the Journal of Mental Health Policy and Economics suggests that regular consumers of cannabis have a lower BMI than those who do not use the drug.

A 2013 study published in the American Journal of Medicine found that cannabis consumers have 16 percent lower levels of fasting insulin and 17 percent lower insulin resistance levels than non-users. The research found “significant associations between marijuana use and smaller waist circumferences.”

And data published in British Medical Journal in 2012 reported that cannabis consumers had a lower prevalence of type 2 diabetes and a lower risk of contracting the disease than did those with no history of cannabis consumption.

In the 2016 study, lead author Isabelle C. Beulaygue from the University of Miami concluded:

“There is a popular belief that people who consume marijuana have the munchies, and so [THEY]are going to eat a lot and gain weight, and we found that it is not necessarily the case.”

Researchers have not identified the reason behind the findings. But some suggest that those who consume cannabis regularly may be able to more easily break down blood sugar, which may help prevent weight gain.
