Published Aug 16, 2018.

XLS Medical is a well-known brand across the UK and Europe, with weight loss products advertised on TV, as well as available from most supermarkets and High street retailers such as Boots and Asda. XLS Medical Hunger Buddy is their appetite suppressant product. The only listed ingredient is a proprietary blend called Redusure, and the only evidence it works is from a trial conducted by the manufacturers. We suggest that you would be better off with a glucomannan-based supplement, as this is a scientifically proven ingredient.


  • Inexpensive

If you are trying to lose weight but keep being derailed from your diet by food cravings and snack attacks, XLS Hunger Buddy proposes a way to help you stay on track.

So, does this appetite suppressant work? We find out.

XLS Medical Hunger Buddy Overview

What you need to know about XLS Medical Hunger Buddy

At first glance, XLS Hunger Buddy looks like an inexpensive supplement that may help reduce your appetite, but this impression is misleading. The daily serving is 6 capsules a day so your 40 capsule bottle will only last a week, making it not quite the good deal it first appears.

The supplement contains a product called Redusure, a trademarked fibre blend based on Glucomannan but lacking vital information about the active ingredient such as serving size. There is no real evidence that it will work as claimed and although some customers have been pleased the overall opinion is fairly indifferent. Some customers have had issues with opening the bottle and with the large size of the capsules.

What are the side effects of XLS Medical Hunger Buddy?

XLS does not contain stimulants and with only one ingredient, side effects are unlikely to be serious.

Potential side effects may include mild gastrointestinal distress, bloating, and constipation.

A few customers have mentioned increased hunger.

It is important to ensure you drink plenty of water throughout the day and when taking the capsules to avoid the risk of choking or blockages.

How much does XLS Medical Hunger Buddy cost?

XLS Hunger Buddy is not expensive. You can buy a bottle of 40 capsules for as little as £7.72 on Amazon. You can also shop around for price from stores such as Superdrug, Asda, and Boots.

This sounds very inexpensive but if you use 6 capsules a day (2 capsules before each meal) your bottle will only last a week.

American customers can buy via Amazon for around $27.00 for a bottle of 40 capsules plus shipping.

XLS Medical Hunger Buddy Key Features

XLS Hunger Buddy is a weight loss supplement that claims to help you avoid hunger and food cravings. It contains a formula called Redusure which is described as a unique fibre complex and the idea is that this will fill you up so that you don’t get those stomach growls and empty feeling in between meals. You are advised to take before meals in order to reduce portion size.

Redusure is a proprietary blend based on Glucomannan. This ingredient is becoming very popular as a weight loss aid. It is a natural fibre derived from a type of yam called the Konjac and is one of the few substances that the European Food Standards Agency (EFSA) have recognised as effective for weight loss support. When taken in the correct quantities (at least 2g a day) it can be effective for weight loss.

According to research into Redusure, we found it was actually composed of three fibrous ingredients. It is obviously a secret formula and although there has been one clinical test carried out by the manufacturers and it looks good, it is all a bit mysterious regarding the true ingredients and serving size per dose.

XLS Medical Hunger Buddy Key Points

  • Contains only a proprietary brand called Redusure as the active ingredient
  • Each bottle contains 40 capsules
  • XLS Supplement

The XLS Hunger Buddy capsules come in a convenient flip-top canister, and this combined with the Hunger Buddy name seems to suggest that you take a capsule whenever you feel a hunger pang or temptation coming on. However, it is probably not a good idea to pop these capsules too often. You will need to maintain regular serving times and not overdo use, or it could lead to blockages or side effects.

Redusure is a proprietary trademarked blend manufactured by InQpharm in Belgium. InQpharm is a global company that researches and develops pharmaceuticals, as well as being the owner of many supplement brands including XLS Medical at one time. The XLS Medical brand was sold to Omega Pharma in 2014 but the two companies still work in close collaboration.

How to Take XLS Medical Hunger Buddy

  • To reduce portion sizes and avoid snack attacks, you are recommended to take two capsules of Hunger Buddy with a full glass of water 30 minutes before main meals, and if needed 1 or 2 in between meals
  • You are recommended to drink enough liquid throughout the day (2L)
  • Do not exceed 9 capsules daily and do not combine Hunger Buddy by XLS Medical with other appetite reducing products
  • Hunger Buddy by XLS Medical is not a meal replacement and should be taken in combination of a healthy and balanced diet

XLS Hunger Buddy seems to be identical to another product called XLS Medical Appetite Reducer which has not been as popular with consumers as some of the other XLS supplements on the market. Possibly XLS Hunger Buddy with its fun name and slicker packaging style has been devised simply to liven up an existing unpopular product?

However looking at the packaging and the Medical name, the XLS Medical Appetite Reducer leaves customers in no doubt that it has to be taken in a similar way to medication i.e. at regular times before meals. This is not the impression that you get from XLS Hunger Buddy.

XLS Medical Hunger Buddy Concerns:

  • Use as directed and you could end up taking a whopping 9 capsules a day!
  • Some customers have already mentioned that the capsules are large. Could these pose an additional choking risk?
  • There is very little real information about Redusure the active ingredient

Probably the most popular XLS Medical supplement is XLS Medical Fat Binder, judging by customer comments. Other supplements include XLS Carb Blocker.

It’s a small point, but it seems that XLS Medical appears to be dropping the Medical part of the name on their recent products.

What does XLS Medical Hunger Buddy claim to do?

According to the advertising, there are four key features to this supplement;

  • Helps to fight food cravings and snack attacks
  • Helps to cut portion sizes
  • Promotes satiety while being gentle on the system
  • Comes in a handy and easy to use push dispenser

Hunger Buddy is clinically proven to promote significant weight loss through reduced food intake. It is particularly suitable for those who constantly have a big appetite and cannot control portion size.

The explanation continues,

It contains the Redusure formula, a unique fibre complex that reduces appetite and provides you with a pleasant feeling of fullness.

The advertising explains how this is achieved,

Hunger Buddy swells up to 200x its original size like a balloon and forms a thick, indigestible gel, which fills up to 30-43% of the stomach. That slows down digestion and promotes a pleasant feeling of satiety. It has been clinically proven that 94% of people experienced a moderate to strong feeling of satiety

It explains how this controls hunger pangs,

The thick, viscous and indigestible gel formed reduces food contact with digestive enzymes and nutrients to the absorptive surface of the intestines. This leads to a flattened and prolonged glucose response after a meal, which prevents the sudden surge of blood glucose levels, thus reducing appetite, hunger pangs and food cravings.

The claims are based are based on clinical testing carried out on by Bongartz et al. 2016

Does XLS Medical Hunger Buddy work?

Let’s take a look at the clinical testing by Bongartz et al. 2016.

The clinical test was carried out by Zaluvida; the parent company of InQpharm who is turn is the manufacturer of Redusure. It took place in Germany and tested 119 people over 12 weeks. Source

At the conclusion of the trial, individuals receiving Redusure™ showed a mean body weight reduction of 3.53 kg (7.78 lbs.) compared to 0.14 kg (0.30 lbs.) in the placebo group. Food cravings and satiety were also measured and participants who received Redusure™ reported a moderate to strong feeling of satiety at 94.7%. No adverse effects were reported during the trial and no clinically significant changes were observed in blood profiles or blood pressure

This sounds good of course. But we do have some concerns that Redusure is not as good as Glucomannan, although it sounds very similar.

The research into Konjac root (Glucomannan) is overwhelmingly good. Several randomized controlled trials have studied the effects of Glucomannan on weight loss. These types of studies are the gold standard of scientific research in humans. The optimum serving size appears to be between 2g to 3g daily.

According to all sources, Glucomannan can swell up to 50 times its original size, not 200 times as claimed by the advertising.

Redusure by contrast only appears to have undergone one clinical test and although is probably based on Glucomannan, it is not the same. It has not undergone the same clinical testing as the natural ingredient so it is hard to evaluate if it really will work as well. In addition, there is no information regarding serving size in the clinical test or in the ingredients list of XLS Hunger Buddy.

XLS Medical Hunger Buddy Side Effects

  • Constipation
  • Bloating

Other side effects are likely to be related to mild gastrointestinal distress.

It is important to ensure you take this supplement with plenty of water to ensure the fibre does not expand before it reaches the stomach. Failure to do this could pose a risk of choking or blockage.

XLS Medical Hunger Buddy Customer Feedback

There is a range of opinion, but interestingly only 42% of customers rated this supplement worthy of a five-star review.

Some customers are satisfied,

Worked brilliant and stopped me snacking

I have been using these for a few weeks and they have definitely curbed my appetite. It stops me snacking and I have lost a few pounds by using these. But I also do exercise a lot these just stopped me from over eating.

This customer felt they were useful if she had exceeded her calorie count for the day,

I brought these for my daughter she notices as soon within half hour of taking them she had bloated feeling so did cut down on eating but she uses them if she feels like she has had her needed calories for the day but feels peckish …so yeah they work

One customer found the bottle was hard to open,

The capsules are not bad, they seem to work. However, the plastic bottle is impossible to open in the way it is supposed to open. It just does not work. I had to use a hammer to break it. And it is not just me that cannot open it. The first time I bought it I got it from a chemist and had to take it back there to be opened. The chemist also had to break it as well…

Some customers have noticed no difference,

Didn’t make any difference. The tablets are very big too. Waste of money.

These did not do a thing. Except make me feel more hungry. Rubbish

Some customers have noticed side effects,

Made me very constipated and bloated, gave up after a week as I gained weight. Maybe I should have given it a bit longer…

Watchdog Verdict

XLS Medical is a well-known and well-respected weight loss brand, but we don’t rate XLS Hunger Buddy very highly. In our opinion, a supplement that contains between 2g to 3g of Glucomannan a day which you take on a regular basis is a much better option than taking Redusure, the sole active ingredient in this supplement.

Although Redusure has been clinically tested, this only seems to have been carried out in one test by the makers of this supplement. It is probably based on Konjac fibre but as ingredients information is unknown, it is just not as proven or as effective.

That said, you mind find XLS Hunger Buddy a convenient way to offset occasional hunger pangs, and if used occasionally you may find that it helps reduce your appetite.

In our opinion, XLS Hunger Buddy is not good enough to approve, and overall we do not recommend XLS Medical Hunger Buddy to the Watchdog readers as a realistic way to support a long-term weight loss plan.
