When you think of using cannabidiol oil, you might think of overeating and potentially gaining weight, since many confuse the derivative with its source: hemp or marijuana. But it’s possible that CBD oil may be helpful when it comes to weight management.
Here’s what California-licensed physician and CBD expert Rachna Patel, MD, and Michael Verbora, MBA, MD, CCFP, the chief medical officer for Ontario-based Aleafia, a medical cannabis care facility, had to say.
Is There Any Evidence Linking CBD to Weight Loss?
One study conducted by researchers at the University of Nebraska College of Medicine in Omaha, NE, and published in 2013 by the American Journal of Medicine found that use of marijuana (or cannabis) was associated with smaller waist circumference.
That study included 4,657 adult men and women who reported using marijuana currently or in the past, and it’s relevant since marijuana contains CBD. However, Dr Patel said she has only seen weight management benefits in her CBD patients as a side effect while treating other conditions.
“I’ve treated patients with CBD oil who have had almost debilitating pain, excessive tiredness from insomnia and anxiety that caused things like nervous eating,” she said. “Once these symptoms are better managed, people are better able to take care of themselves, make healthier food choices, exercise more, and live a better quality of life.”
Dr Patel said animal studies have also shown an increase in metabolism linked to CBD consumption, but clinically, she hasn’t seen that in her practice.
Dr Verbora, who has been working in the medical cannabis space for four years, also referenced animal studies. In those studies, cannabidiol has been shown to stimulate genes and proteins that enhance the breakdown and oxidation of fat, increase the number and activity of mitochondria (which increases the body’s ability to burn calories), and decrease fat cell generation. However, “There is no evidence to show that using CBD will cause weight loss in humans,” he said.
While Dr Verbora hasn’t prescribed CBD for weight management, he has also seen it as a side effect of treating chronic pain in some patients. He noted an overall ability to increase activity levels could have been responsible for that weight loss.
Are There Any Concerns About Weight Gain?
Dr Patel pointed out that the common notion that marijuana itself stimulates appetite has likely come from people purchasing marijuana with high levels of tetrahydrocannabinol (THC) off the black market for the purposes of getting high. In Dr Patel’s experience with her patients, use of CBD oil, as derived from marijuana or hemp, did not coincide with an increase in appetite. (CBD contains very low levels of THC.)
Dr Verbora noted that while it won’t hurt you, more studies are needed before cannabidiol can be used for weight management. “It’s not recommended given it’s still unknown and can be expensive,” he said. “While CBD is safe and doesn’t cause harm, it could just be an expensive oil that doesn’t help in the case of weight management.”
