A recent study has revealed that frequent cannabis users have lower body mass index (BMI) and decreased risk of diabetes, overturning the widespread belief that marijuana consumption causes weight gain.
Published on June 2nd, the study found that even low doses of THC—the main psychoactive component of marijuana—given to adolescent mice had long-lasting effects on their metabolic system. Drug-free male mice exposed to THC during adolescence saw reduced fat mass, increased lean mass, higher-than-average body temperatures, and partial resistance to both obesity and hyperglycemia.
While this benefit may come with a price—including a reduced ability to use fuel from fat stores—it can lead us to reconsider our perceptions of cannabis use and its potential health benefits. By looking into the molecular anomalies in fat tissue caused by THC, researchers hope to better understand how marijuana consumption affects BMI and diabetes risk in humans.
Study’s Cannabis Impact on BMI and Diabetes Risk
The study found that daily low-dose administration of THC to adolescent mice caused an adult metabolic phenotype characterized by reduced fat mass, increased lean mass, and partial resistance to diet-induced obesity. This suggests that cannabis consumption may impact body mass index (BMI), even in small doses.
Although further research is needed to investigate the effects of marijuana use on BMI in humans, it appears that cannabis has the potential to alter metabolism—which could explain why frequent users tend to have lower BMIs than non-users.
In addition to affecting BMI, THC administration to adolescent mice also resulted in impaired cold- and β-adrenergic receptor-stimulated lipolysis—which could explain why frequent cannabis users have a decreased risk of developing diabetes.
The study found regular marijuana use was associated with increased insulin sensitivity and an improved cardiometabolic risk profile. While further studies are needed to investigate how these findings can be applied to humans, it is clear that cannabis can potentially lower the risk of diabetes in some individuals.
The Munchies Paradox
The ‘munchies’—or the intense desire to eat after consuming cannabis—are well-known among drug users. This phenomenon has led many to believe that marijuana consumption increases appetite and body weight.
However, this study found that despite increased appetite, frequent cannabis use was associated with lower BMIs in male mice. The authors suggest that these positive effects may be due to THC’s impact on energy balance and metabolism—which could explain why users tend to have leaner physiques than those who don’t consume marijuana regularly.
Study Findings on Molecular Anomalies & Organ Dysfunction
The study found that adolescent exposure to THC can lead to molecular anomalies in the adipose organ—including ectopic overexpression of muscle-associated proteins and heightened anabolic processing.
Such changes can increase thermogenesis and decrease lipolysis, leading to a “pseudo-lean” state that superficially resembles healthy leanness but might be rooted in adipose organ dysfunction. Understanding how marijuana use affects fat tissue metabolism is critical for determining the long-term impacts of cannabis consumption on BMI and diabetes risk.
While this study provides valuable insight into how cannabis consumption can affect BMI and diabetes risk in humans, more research is needed to shed light on the potential long-term effects/benefits of marijuana use.
Future studies should investigate whether THC administration can cause metabolic consequences in other organs, such as the liver and pancreas, and examine how this affects overall BMI and diabetes risk.
Additionally, further research is needed to determine if these findings are transferable to human subjects—and what doses of cannabis produce positive health outcomes for users.
Unfortunately, there is a great deal of misinformation around cannabis use—some of which may be rooted in pseudo-scientific beliefs or anecdotal evidence that does not reflect the latest findings from scientific studies.
To accurately assess the potential benefits and risks associated with cannabis use, it is important to differentiate between data-driven research and anecdotal evidence. By being mindful of this distinction, we can ensure that we make decisions about marijuana consumption based on actual scientific data—not unfounded beliefs or personal experiences.
This study found that frequent cannabis users have lower BMIs and decreased risk of diabetes, overturning the widespread belief that marijuana consumption causes weight gain. Further research is needed to investigate how these findings can be applied to humans, but THC administration can reduce fat mass, increase lean mass and lower the risk of diabetes.
Understanding how marijuana use affects fat tissue metabolism is critical for determining the long-term impacts of cannabis consumption on BMI and diabetes risk, and it is essential to differentiate between scientific data and pseudo-science when making decisions about cannabis use.
By doing so, we can ensure that we are making informed decisions about our health—based on actual data rather than unfounded beliefs or personal experiences.
