Pot users avoiding pot bellies: research
All the snacking doesn’t seem to pack on pounds
When Cody Lindsay gets the munchies, fuzzy peach candies are his go-to snack. The former navy vet, who served as a cook and now publishes recipes as The Wellness Soldier, is also known for his decadent chocolate cheesecake pot brownies.
But while the 37-year-old describes himself as “a touch overweight,” he doesn’t think the onslaught of edibles about to hit the Canadian market puts us at risk of a collective pot belly.
Research on the correlation between cannabis consumption and appetite dates back decades. A 1988 study out of Johns Hopkins University, for example, found that subjects who smoked marijuana ate 40 per cent more calories than a control group.
Fast-forward 30 years and a survey commissioned by licensed marijuana retailer National Access Cannabis found that 28 per cent of 1,525 respondents cited eating as the most enjoyable activity after ingesting marijuana — compared with only 17.5 per cent who cited “having sex.”
There’s a scientific explanation for these cravings. THC, or tetrahydrocannabinol, the main psychoactive constituent of cannabis, stimulates the release of ghrelin, a hormone normally released when the stomach is empty. According to a study conducted by a neuroscientist in Bordeaux, THC may also enhance the olfactory system, another trigger for eating.
That marijuana specifically spikes cravings for junk food is also clear. By tracking retail data in American states that had legalized cannabis, economists found that monthly sales of “high-calorie food” increased by 3.1 per cent for ice cream, 4.1 per cent for cookies and 5.3 per cent for chips.
All that snacking, however, does not seem to pack on the pounds. Researchers at Michigan State University looked at data on 33,000 subjects collected over a three-year period by the National Epidemiologic Survey of Alcohol and Related Conditions.
“We found that users, even those who just started, were more likely to be at a normal, healthier weight and stay at that weight,” said lead author Omayma Alshaarawy. “Only 15 per cent of persistent users were considered obese compared to 20 per cent of non-users.”
While investigating the effect of cannabis use on the appetite of cancer patients, Marialuisa Vigano also found there was an increase in appetite but “no statistically significant increase in weight.”
Weed as diet aid isn’t quite there yet, though.
Antonio Vigano is an oncologist and professor at Mcgill University who sees significant decrease in appetite among his patients. So when his daughter, then 17, conducted a study showing cannabis consumption improved their appetites, he encouraged her to share her findings with professional groups.
But he warns that recreational users may suffer indirect negative consequences to marijuana consumption that make it a poor approach to simply slimming down.
Users may be more prone to consuming alcohol, for example, or may be less active. “These factors could aggravate pre-existing conditions such as obesity, and borderline glucose intolerance, as well as increase the risk of diabetes,” he said.
Michigan State’s Alshaarawy is similarly cautious. She speculated that the difference “could be the cannabis use itself, which can modify how certain cells, or receptors, respond in the body and can ultimately affect weight gain.” But it could equally be that cannabis users are conscious of the weight gain that can come from the munchies, so they adjust their diets accordingly.
Lindsay says, he now plans ahead when he consumes cannabis so he has healthy options on hand.
