Cannabis has come a long way from its days as a taboo topic. As the use of Mary Jane becomes more common both medically and recreationally, so does the conversation around its role in weight loss.
If you've ever wondered, "Can smoking weed help me lose weight?" you're not alone.
To help you see through the smoke, we dive into the science of how cannabis interacts with appetite, metabolism, weight gain, and exercise and explore whether it’s a good idea to rely on it as a weight loss tool. Plus, we look at CBD’s role and discuss sustainable approaches to shedding those extra kilos.
We turn to the research to answer one question: does lighting up help you slim down?
Can smoking weed lead to weight loss?
The idea of losing weight by simply smoking a spliff might sound appealing, but the reality is a bit more complicated. Cannabis has a mixed reputation when it comes to appetite and weight.
While some people might experience an increase in hunger and potentially gain weight when smoking weed, others report the opposite effect. So, let’s break it down and see what’s really going on.
Weed and appetite
You’ve probably heard of the munchies — a well-documented side effect of smoking cannabis where suddenly everything in your fridge looks like the most delicious thing ever.
This effect is due to THC — the psychoactive compound in cannabis — which interacts with the endocannabinoid system in our body.
THC and weight gain
THC binds to CB1 receptors in the brain, which triggers the release of ghrelin, the hormone responsible for making us feel hungry [1]. CB1 interacts with a type of neuron in your brain called POMC, signalling to your body that you’re no longer satiated and causing you to overeat and potentially gain weight [2].
CB1 also impacts appetite in two more ways, both working to turn your cupboard into an ‘all you can eat’ buffet: the basal ganglia (where it amps up the pleasure associated with eating) and the limbic forebrain (where it enhances food palatability — quite literally making food taste better) [3].
But here’s the twist: while THC might make you hungry in the short term, not everyone experiences this effect the same way, and not everyone experiences weight gain.
THC and appetite
Some people may find that after regular use, their appetite levels off, and they no longer feel the need to raid the kitchen.
In fact, some studies suggest that chronic cannabis users may actually have lower body mass index (BMI) than non-users and are at a lower risk of type 2 diabetes [4][5].
So, what gives? It seems that the relationship between weed, appetite, and weight gain is complex and influenced by a bunch of factors, including how often you use it and your own body’s unique chemistry.
Weed and metabolism
Now, let’s talk about metabolism — the process by which your body converts what you eat and drink into energy. There’s some evidence to suggest that smoking marijuana can give your metabolism a little boost [6].
The endocannabinoid system, particularly the CB1 and CB2 receptors, plays a role in regulating energy balance and metabolism.
CBD and metabolism
Research also suggests that CBD (another non-psychoactive component of cannabis) might increase the rate at which your body breaks down fats and improve insulin sensitivity [7].
This could help with glucose management and possibly reduce the risk of developing obesity, potentially helping you lose weight. The truth is, your body’s metabolic response to cannabis is likely unique to you, influenced by things like your genetic makeup and how you typically respond to THC.
Weed and exercise
Does the idea of pumping some iron sound appealing when you’re blazed? Or would you rather stick needles in your eyes than hit the gym while high? Regardless of your answer, you’re not alone.
The connection between marijuana users and exercise is a hot topic, and while the research is still emerging, there are some interesting findings. Anecdotally, some people swear by a pre-workout puff, claiming it makes exercise more enjoyable or helps them push through discomfort.
This is no surprise, as the endocannabinoid system is also linked to mood, pain, and motivation, which are all key factors in how we experience exercise.
A 2022 study found that a significant number of cannabis users often smoked marijuana before or after exercise, reporting that it enhances their workout experience and aids in recovery [8].
However, it’s not all smooth sailing. While some people feel more motivated to exercise after using cannabis, it can also compromise coordination and reaction time, which isn’t ideal for workouts that demand accuracy and attention.
As with many things cannabis-related, the effects can vary greatly from person to person.
The risks of using cannabis as a weight loss tool
Given the mixed bag of effects that cannabis can have on appetite, metabolism, and exercise, it’s clear that using it as a weight loss tool isn’t straightforward — and it comes with risks.
For starters, the psychoactive effects of THC can sometimes lead to poor decision-making [9]. Imagine setting out to manage your weight, only to find yourself snacking uncontrollably on junk food after a smoke session.
While some people might experience a reduced appetite, others might end up eating more than they planned, particularly foods that are high in calories and low in nutrition, causing weight gain.
Cannabis affects more than just body weight
Additionally, there’s the matter of long-term health effects. Regular cannabis use, especially when smoked, has been linked to potential risks like respiratory issues, dependency, and cognitive impairment [10].
It’s important to weigh these potential downsides against any possible benefits you might see in terms of body weight management. And then there’s the unpredictability factor. Cannabis affects everyone differently, and what works for one person might not work for another.
Some might see a decrease in appetite and weight, while others could experience no change — some experiencing significant weight gain.
So, if you’re thinking about using cannabis for weight loss, it’s important to consider all these variables.
If you're concerned about your tolerance and feel you may be smoking weed more than you should, drug alcohol abuse services such as DirectLine (1800 888 236) are available to support you and offer you guidance.
Can CBD help with weight loss?
CBD, or cannabidiol, is another compound found in cannabis, and unlike THC, it doesn’t get you high. Over the past few years, CBD has been touted for a range of health benefits, including its potential effects on weight.
Research suggests that CBD interacts with the endocannabinoid system differently than THC.
Some studies indicate that CBD might help reduce appetite and even promote fat browning — a process where white fat (the kind that stores energy) is converted into brown fat (the kind that burns energy) [11].
CBD also has anti-inflammatory properties and may help manage stress and anxiety, which are often linked to overeating and weight gain [12].
But before you rush out to stock up on CBD gummies, it’s important to note that most of the research is still in its early stages. Many studies have been done on animals rather than humans, and the results are mixed.
Some cannabis users might find that CBD helps them maintain a healthy weight, but as with THC, the effects can vary. It’s always a good idea to approach with caution and keep your expectations realistic.
Approaching weight loss sustainably
While the idea of using cannabis or CBD for weight loss might sound appealing, it’s crucial to focus on a sustainable, healthy approach to shedding kilos. Relying on cannabis as your primary weight loss strategy isn’t recommended due to its unpredictable effects and potential risks.
There are plenty of healthier ways to approach weight loss that are better for your overall well-being. Let’s dive into some tips for sustainable, long-term weight management.
Losing weight in a healthy way is all about making small, manageable changes, like working out a bit more often, cutting back on sugary snacks, and eating a more balanced diet.
These little adjustments are key to helping you lose weight, and they make it easier to stick to your goals while embracing a healthier lifestyle.
Here are some tips to keep in mind:
- Balanced diet: Focus on whole, nutrient-dense foods like fruits, vegetables, whole grains, and lean proteins; you’ll find yourself naturally craving less sugary snacks when you pack your diet full of good stuff.
- Regular exercise: Aim for a mix of cardio and strength training exercises. The key to sticking with regular exercise is finding an activity that you genuinely enjoy. Incidental exercise counts too.
- Mindful eating: Pay attention to what and how much you’re eating. Mindful eating practices can help you avoid overeating and help you make food choices that align with your goals.
- Behavioural changes: Consider the bigger picture, including your mental health, stress levels, and sleep patterns. These factors can all play a role in your weight and may lead to a reduced body mass index.
When it comes to weight loss, it’s important to see the journey as more than just following a strict diet, experimenting with marijuana use or hitting the gym for a few weeks.
True, lasting weight loss is best approached through a holistic lens, where making sustainable lifestyle changes becomes the foundation for long-term success.
