The Modius Advanced Weight Loss headset is advertised as a smarter way to lose weight by the use of neuroscience technology. According to the advertising, you can lose pounds of weight simply by wearing the headset and connecting straight into your brain.

Is this the future of successful weight loss? We take a look.


  • Many people report that it works
  • Could be an easy method of weight loss
  • Featured in the media


  • Expensive
  • Money-back guarantee only applies if you buy from the official website and not Amazon
  • Many people have reported technical problems
  • Can cause headaches and dizziness
Modius comes from a company called Neurovalens founded by British scientists, CEO Dr Jason Mckeown, a doctor from Dromore in Northern Ireland, working with a neuroscientist called Paul McGeoch. Both men were based at UCSD – the University of California at San Diego. Neurovalens is a new tech firm that has won awards for business and technology.

Modius Overview

What you need to know about Modius

Modius is an electronic device that causes weight loss by directing electrical impulses into the areas of the brain that regulate weight and appetite. Although some people have been happy with the headset, there have been technical problems and it obviously does not work for all users. If you buy directly from the Modius website, you are covered by a 90-day money-back guarantee, but beware. This money-back offer does not seem to apply to purchases from Amazon and other 3rd party sites, and at £369.00, this is a major consideration for most users.

What are the side effects of Modius?

Some customers have mentioned side effects. Many people have mentioned headaches. Some users have mentioned a rocking sensation or dizziness.

Worryingly for a weight loss supplement, some customers have mentioned an increased appetite for carbs and have actually gained weight.

How much does Modius cost?

Modius is very expensive.

If you buy from the Modius healthcare website it costs £369.00. Customers from outside the UK can also buy directly from the site with prices provided in local currencies including EU and USD, making it around $500 for US customers. Shipping is free.

The headset comes with 150 pads and 100 cleaning wipes which is sufficient for 12 weeks use. You can buy these separately from the website for around £30.00 a pack. A subscribe and save option is available that gives you a small discount.

You can also buy Modius via Amazon UK where it costs £369.00, which is the same price as available from the official website. However, there does not seem to be a money-back guarantee if you choose this option.

Modius Key Features

Modius is a weight loss invention that looks very different from anything else we have seen on the market. Forget weight loss patches, magnets, or electrical waist trim belts, Modius is hitting the news with this novel invention that is all about neuroscience!

Modius Key Points

  • Advertised as groundbreaking technology
  • Been featured in the media
  • Supposedly tricks your brain into believing your body is more active

Modius comes in the form of a headset with two electrode pads that you stick to your head behind your ears and wear for around an hour a day. According to the science, this sends electrical impulses to the part of the brain that controls appetite, cravings, and feelings of fullness.

Weight loss results don’t seem that extreme, but considering you don’t actually have to do anything save wear a headset, it will probably appeal to some people. According to the advertising, 80% of users have lost 9lbs of weight within three months. The inventor of Modius – Dr Jason Mckeown claims it reduced his own body fat by 44%.

How to Use Modius

  • Charge the headset
  • Download the App and create an account
  • Follow the instructions
  • Each session should last one hour. You should be seated because it can cause dizziness. You can control the strength of the effect via the App

To use you connect the headset to your smartphone via Bluetooth. The process is controlled by an App that enables you to control the settings, time the session, check your progress, and engage with other users in the online community.

Modius has hit the news. It has been featured in the media including This Morning with Holly Willoughby and Philip Schofield. There have been articles about it in the Daily Mail, Men’s Health, and features on the BBC and Sky News.

Modius Concerns

  • May cause dizziness.
  • No real evidence that it works as described
  • Looks like an overpriced novelty product that many people may quickly tire of
  • The money-back guarantee only seems to apply if you buy directly from the Modius Health website

Modius is the only product from Neurovalens, the company founded by inventor and CEO Dr Jason Mckeown. The company has won a string of business awards, including an Innovation Award at CES 2018 and Best Innovation at the Yahoo 2018 Sports Technology Awards. It has also been a Northern Ireland success story, winning two awards in 2018 from Barclays for best business startup.

What does Modius claim to do?

The basic way that Modius works is that it alters your metabolism so your brain feels that you are being more active. This means that your body does not store as much fat as usual. Source

According to the information on the official website,

“Our brain constantly monitors how much we should weigh and automatically regulates this for us by changing our cravings, appetite and sense of fullness. When you are trying to lose weight, these are the key side effects that are known to make someone’s weight loss journey harder.

Modius makes the whole process easier by stimulating the vestibular nerve which we know influences the hypothalamus and brain stem to reduce your cravings and appetite.”

Cravings are reduced too.

“Modius targets your cravings by reducing your desire for carbohydrates making it easier to resist high calorie snacks.”

Appetite is reduced,

“The hypothalamus regulates appetite by receiving feedback from hormones such as leptin, insulin and ghrelin. The hypothalamus uses this feedback to automatically control your hunger. However, when body weight goes down the hypothalamus unfortunately increases appetite significantly.

Modius targets your appetite during this time by controlling your appetite and stopping it from increasing significantly when you are trying to lose weight.”

Feelings of fullness are increased too,

“Modius targets your feeling of fullness which should leave you feeling satisfied quicker and stop you overeating”

Does Modius work?

It might work. We don’t claim to be neuroscientists and the Modius advertising looks convincing and scientific. However, it is important to point out that all the testing has been carried out by Neurovalens, and most of this did not look at the effects on real people. There was only one human clinical trial which followed 9 people over 16 weeks, and the weight loss experienced by this study group was not significant.

According to neuroscientist and author Sandra Aarmot, the evidence for Modius is not convincing as the device has not undergone sufficient clinical testing.

Despite the hype and the business awards and the general buzz around Modius, there are no real guarantees that this headset will work as claimed. The advertising states it helps 80% of people lose 9lbs of weight over 3 months which seems OK, but doesn’t reflect what actually happened in the small clinical trial. In addition, most customers writing on Amazon have not lost this amount of weight.

The bottom line is that there is no real proof the Modius will help weight loss as described. On the plus side, there is no evidence that says it won’t work. Source

Modius Customer Feedback

According to the Modius advertising, thousands of people have used the headset and have successfully lost weight. There are testimonials and pictures posted on the official website. One customer called Denise McCabe reported losing 65 lbs in less than a year. Another customer lost 44lbs in 13 months. All the stories look convincing, but we have no way of knowing whether they are genuine.

The same positive results were not seen in Amazon users.

Positive comments include,

I purchased one of these in its start up campaign. I had a problem with the headset as it refused to charge. They sent me a replacement straight away. So customer service is excellent. I find the device reduces my appetite and if i acknowledge this and don’t just increase my food intake i lose weight. It has proved successful, but like all things in life you have to put something in yourself.

Some customers are happy and are losing weight. Improved sleep is an added benefit that many people have mentioned,

I’ve been using my Modius for a few weeks now and must say I love it! Initially I noticed it really improved my quality of sleep (unexpected bonus), and more recently I’ve become aware that my appetite is way down and I’m finding my tastes changing…

Some customers have struggled with the software especially if using with Android devices,

Do not buy this item if you have a phone running on Android OS. Some Android OS phones work with this product but going by reviews, a majority don’t and it costs a lot of money to chance. I have tried on multiple android devices by different manufactures and the headset can’t connect and the app crashes when you try to view the sessions page.

One customer found he had a fault with his headset and was fed up by the lack of customer support,

Unfortunately, my Modius failed the first test, charging. A flashing amber light indicated a charging fault. The information provided with the device, which was very little, suggested trying a different USB plug. I tried two different USB plugs and two USB leads but to no avail, still the flashing amber light.

Not a problem, I’ll give them a call … No telephone support. Okay, I’ll chat with an engineer online … No online chat support. If you have an issue, you have to use email and they try to respond within 24 hours ….. Sorry, not good enough. It’s amazing how quickly they can respond when there is a chance of a sale on platforms like Facebook, but not so fast if you need help after paying your money.

This customer experienced headaches while using, and then struggled to return to the headset because he bought it from Amazon rather than the official website,

Having trouble returning despite the 90day promise. Although setup as a user and login on the app website doesn’t recognise my details. Not even an option on Amazon!

Experienced headaches day after use. GP advised not to use after headaches did not happen on days of no use. This maybe unique to me but despite trying it and experimenting I’ve not had a headache/fuzzy head since stopping the use.

Other technical problems include not connecting to Bluetooth and not charging properly.

Some customers have mentioned zero effects,

Did nothing

Some customers feel that it works, but that it is not easy to use because of side effects,

…What it does is it suppresses your appetite making me easier to skip a meal or doing intermittent fasting. I loss 2 kg as the result…Hopefully from the fat… there is no doubt that my waistline is smaller… One of the down side is you have to wear it for one hour and make you have the free time to spare as it is not easy to work while having rocking sensation. Hence the 4 star.

A few customers have said that it has caused an increased appetite,

3 months since I had it and using it daily, I have noticed an increase of a appetite and absolutely no weight loss, but gained some more

Modius Money-Back Guarantee

You are not covered by a guarantee if you buy via Amazon.

If you buy through the Modius website, you are covered by a 90-day money-back guarantee. Here’s what the company say about it.

We will refund the amount received by us and are not liable for any fees or fluctuations in exchange rate between the date purchased and the date refunded.”

Watchdog Verdict

Although we are always interested in new and novel ways to make weight loss easier, in our opinion, Modius looks like an expensive gimmick. According to the advertising, most people lose around 9lbs in 3 months so results are reasonable when compared to other methods of weight loss.

In addition, you do have the inconvenience of wearing the headset for an hour a day, as well as all that faff of setting it up and using the app. Even if you lose your 3lbs of weight a month, we can’t help thinking that taking a little walk or doing some exercise will be much better for weight loss and general health. All health advice is to move away from the computer, and an app that tells your brain that you are more active than you actually are is not going to make you feel better or fitter.

There are obviously some issues with the technology, and many people have struggled in connecting the headset to android and other issues about recharging and Bluetooth.

Finally, we are very concerned that if you buy it via Amazon you are not covered by the money-back guarantee. We have checked over this last point very carefully, but there is no mention of this applying to Amazon customers, only to products purchased directly from Modius Health website.

Overall, we are not impressed with Modius so we do not recommend it to the watchdog readers.
