Jason Fung Tips: Vagus Nerve Stimulation Device to Increase HRV
Key Takeaways
The vagus nerve is a key part of your parasympathetic nervous system, impacting stress levels and overall health.
Improving your heart rate variability (HRV) through vagus nerve stimulation (VNS) can enhance your well-being.
Jason Fung, MD, a nephrologist is a prominent figure in the intermittent fasting and low-carb diet space for metabolic health.
While he does not promote VNS, followers of his methods can benefit from the beneficial effects of VNS, such as mood regulation.
Biohacking with Vagus Nerve Stimulation
Have you ever wondered how to calm your nerves, literally?
Well, there's a biohacking secret that's gaining traction, and it involves stimulating a nerve that runs from your brainstem all the way to your abdomen. It's called the vagus nerve, and it's a major player in the parasympathetic nervous system, which controls your body's rest and digest functions.
What is the Vagus Nerve?
The vagus nerve is one of the longest nerves in your body and it's part of the autonomic nervous system. It sends signals to and from the brain to various organs, regulating functions like heart rate, digestion, and immune response. When you stimulate the vagus nerve, it can help to reduce stress, improve sleep, and even boost your mood. But most importantly, it can increase your HRV, which is a measure of the variation in time between each heartbeat.
Why HRV Matters for Your Well-being
HRV is crucial for your well-being as it signifies how well your body responds to stress, with a higher HRV indicating better adaptability. This resilience is tied to improved cardiovascular health, lower stress, and a stronger immune system, making the enhancement of HRV a valuable health goal. VNS emerges as a practical tool to aid in this endeavor.
The Science Behind Vagus Nerve Stimulation (VNS)
VNS is a scientifically supported technique beneficial for enhancing mental well-being and reducing stress responses by activating the parasympathetic nervous system. It's particularly effective for those with anxiety, depression, or chronic stress, offering a pathway to calm and well-being through neurological modulation.

Jason Fung Tips: Vagus Nerve Stimulation Device to Increase HRV
Already Following Jason Fung? Then You Need VNS
Canadian nephrologist Jason Fung is renowned for his work on intermittent fasting and low-carbohydrate diets, as detailed in his best-selling books, The Obesity Code and The Diabetes Code. He also directs the Public Health Collaboration and co-founded The Fasting Method, which helps people lose weight and reverse type 2 diabetes through intermittent fasting.
For those following Fung’s approach to weight loss and diabetes management, incorporating Vagus Nerve Stimulation (VNS) might offer additional benefits. VNS could complement low-carb diets and intermittent fasting in several ways:
Enhanced Insulin Sensitivity
VNS may improve insulin sensitivity, crucial for effective blood sugar management. This supports the metabolic goals of a low-carb diet by helping the body process glucose more efficiently. While a 2016 study on rats suggested this effect, further research is needed to confirm these benefits in humans.
Improved Appetite Regulation
VNS may influence appetite and satiety signals, potentially aiding in the management of hunger and adherence to intermittent fasting and low-carb diets. A 2014 study indicated that VNS could lead to weight loss in animals, but the results in humans have been inconsistent, highlighting the need for more research.
Better Stress Management
VNS has demonstrated effects on stress and mood regulation. Effective stress management can reduce emotional eating and enhance the discipline needed for both intermittent fasting and low-carb diets, contributing to overall success in these dietary strategies.
Jason Fung is a well-known expert on intermittent fasting and low-carb diets.
Lifestyle Changes to Complement VNS Benefits
If you’re ready to give VNS a try, a number of adjunct activities can help you enhance its effects. You’ll find some suggestions in this section.
Exercise
Incorporating regular exercise is critical for enhancing VNS benefits. It does not matter if you prefer low-impact exercises like walking or something as intense as Brazilian jiu-jitsu; the goal is consistency, which ultimately ensures long-term adherence and lasting health benefits.
Diet
A proper diet has an indirect effect on your VNS practice by improving your overall health. For instance, a diet rich in anti-inflammatory foods, such as fruits, vegetables, nuts, and fatty fish, supports overall nervous system health. Moreover, adequate intake of essential nutrients like omega-3 fatty acids, magnesium, and B vitamins is crucial for nerve health and function.
Proper Sleep
Quality sleep supports not only recovery following a workout but also overall nervous system health, which can enhance the response to VNS. Proper sleep helps maintain the balance between the sympathetic and parasympathetic nervous systems, which VNS aims to modulate.
Meditation
Without the use of a VNS device, you would rely on natural methods like meditation. Meditation can naturally enhance vagal tone by stimulating the vagus nerve through relaxation and deep breathing techniques. This may further amplify the effects of VNS by promoting greater parasympathetic activity.
Step-by-Step Guide on Using a VNS Device
Using a VNS device might seem intimidating at first, but it's actually quite straightforward. Let's walk through the process step by step.
Choosing the Right VNS Device
When considering a VNS device, look for a device that's backed by clinical research and is reviewed favorably by users. It's also important to choose one that fits comfortably into your lifestyle. For example, if you lead an active lifestyle, a hands-free VNS device would be preferable.
A hands-free device like Pulsetto makes it easy to do other tasks while stimulating the vagus nerve.
Setting Up Your VNS Device for the First Time
Once you've got your device, it's time to set it up. Start by charging the device if needed, and make sure you understand where and how to position it for optimal stimulation of the vagus nerve. The first session is about getting used to the sensation and the process, so take it slow and don't rush the experience.

It’s also clinically tested and designed for daily use. Since it’s non-invasive and drug-free, there’s no risk of dependency or side effects. You can use it once a day or several times depending on your needs, before bed, during a stressful moment, or to reset between work tasks. It’s safe, simple, and built for consistency, so the more you use it, the better your nervous system functions over time.
Above all, Pulsetto devices have performed more than 1.5 million simulations already with zero side effects.
How fast will I feel results?
Most users feel noticeably calmer within just 4 minutes. That’s because Pulsetto uses clinically proven vagus nerve stimulation to rapidly shift your nervous system out of fight-or-flight mode and into rest-and-digest. Unlike supplements or meditation apps, there’s no need to wait weeks for subtle changes, relief starts almost immediately. Over time, regular use also strengthens your vagal tone, making you more resilient to stress and better able to stay calm throughout the day.
What does it feel like?
It feels pleasant! Most users describe it as a slight tingling sensation, or a tickle. It’s designed to relax you, so it’s completely pain-free — otherwise it wouldn’t be very calming, would it!
What exactly is the vagus nerve, and why does it matter?
The vagus nerve is the longest cranial nerve in your body, and it plays a crucial role in regulating your mood, stress, digestion, heart rate, and sleep. It’s like your body’s internal switchboard for calm and recovery. Pulsetto gently stimulates this nerve to activate the parasympathetic nervous system, helping you slow down, relax, and restore balance. It’s the same nerve doctors stimulate in clinical settings to treat mood and anxiety disorders, but Pulsetto brings this powerful science home.
Can Pulsetto help me sleep better?
Yes, Pulsetto helps you fall asleep faster, stay asleep longer, and wake up more refreshed. By stimulating your vagus nerve, it activates your parasympathetic nervous system (the one responsible for rest and recovery), helping your body power down naturally. It’s a non-invasive, drug-free solution that works with your body’s own biology. Whether you struggle with racing thoughts, trouble falling asleep, or restless nights, Pulsetto helps create the calm, balanced state your body needs to enter deep, restorative sleep.
What’s included in the Pulsetto App? Is it free?
Yes, the app is 100% free and comes included with the Pulsetto device. It offers 5 unlimited stimulation programs for sleep improvement, nervousness, stress reduction, burnout, and pain management.
The app works with both iOS and Android. It also has a specialized Sound Library filled with sounds specifically designed for Pulsetto, which improve the overall experience.
Do I need to be tech-savvy to use it?
Not at all. Pulsetto is designed to be incredibly easy to use. Just place it around your neck, open the free app, and start your session. The app walks you through everything, from choosing the type of session to adjusting intensity levels. Even if you're not into tech, you’ll find it intuitive and seamless. It’s as easy as putting on a pair of headphones and pressing play, except instead of sound, you're stimulating calm.
Can Pulsetto really help with stress and anxiety?
Yes, and that’s where Pulsetto truly shines. Chronic stress and anxiety are often caused by an overactive sympathetic nervous system (the fight-or-flight response). Pulsetto works by activating the opposite system, the parasympathetic, which signals to your body that it’s safe, helping you relax almost instantly. Whether you're managing daily overwhelm or deeper emotional stress, Pulsetto gives you a powerful tool to self-regulate in a natural, consistent way. It’s peace of mind at the push of a button.
How is Pulsetto different from other wellness tools like meditation apps or supplements?
Meditation apps and supplements can help, but they often take time, focus, and commitment. Pulsetto works physically, not just mentally. By directly stimulating the vagus nerve, it taps into your nervous system’s core functions, creating a fast and reliable physiological shift. You don’t need to “get in the zone” or wait weeks for effects. It’s consistent, clinically supported, and easy to use daily. Pulsetto is not just a wellness tool, it’s a nervous system upgrade.
What if I don’t struggle with anxiety or sleep, can Pulsetto still benefit me?
Yes! Even if you’re not actively struggling, Pulsetto can still improve your overall health and performance. Regular vagus nerve stimulation boosts focus, sharpens mental clarity, supports digestion, reduces inflammation, and even enhances athletic recovery. Think of it like exercise for your nervous system, the more you use it, the stronger and more balanced it becomes. Pulsetto is perfect for anyone who wants to feel more grounded, energized, and resilient in their everyday life.
