Is Hunger Buster a way to get “beach body ready” as the Protein World advertising suggests? Or, is this product and company just a whole lot of hype and slick advertising? We take an in-depth look at Protein World Hunger Buster to find out more.

Protein World Hunger Buster Key Features

Protein World Hunger Buster is a fairly simple looking weight loss supplement. It does not contain stimulants or lots of ingredients in unknown quantities, like so many others on the market.

Instead, the capsules contain just two ingredients; Konjac Glucomannan and Garcinia Cambogia, According to the product information, this the perfect combination to increase fat metabolism.

Protein World Hunger Buster Key Points

  • Hunger Buster is a Protein World supplement
  • Each bottle contains 90 capsules or 45 servings
  • You are recommended to take 6 capsules each day

Glucomannan is a water-soluble polysaccharide that is considered a dietary fiber. It is a natural sugar that is derived from the root of the Konjac plant a type of Japanese Yam.

Glucomannan is contained in numerous weight loss supplements. This indigestible fibre stays in your stomach for a long time and there is some evidence that it is effective for weight loss because it reduces your appetite by making you feel full. It is associated with a risk of choking so it is important to ensure that you take Glucomannan with plenty of water to wash it down.

The European Food Standards Agency (EFSA) considers Glucomannan potentially beneficial for weight loss if taken in the right quantities and the way as described.

The other ingredient is Garcinia Cambogia. This extract derived from a South Asian fruit that is similar to the tamarind has become flavour of the month for weight loss. It was featured by Dr Oz – the well-known American celebrity weight loss expert, who claimed it as a miracle product.

Garcinia Cambogia is believed to be a natural carb blocker. It contains hydroxycitric acid, which is believed to inhibit a vital enzyme in the body called citrate amaylse. This enzyme breaks the carbs that you eat into fat so stopping this process means that a percentage of the carbs that you eat are unabsorbed by your body. It is also believed to increase serotonin, the brains feel-good chemical, so may help you avoid depressive eating and comfort snacking.

All this sounds good but there is a lack of clinical evidence to prove the claims for Garcinia Cambogia.

How to Take Protein World Hunger Buster

Consume 2 capsules 1-3 times per day an hour before meals.

Protein World is a well-known British company who specialise in weight loss supplements. As the name suggests, many of the supplements are based on protein and this company is an innovator in bringing protein to general weight loss supplements.

Protein has been a mainstay of bodybuilding supplements for years. It helps build muscle and is a support for exercise and training. Now protein is being marketed as a way to lose weight and maintain muscle for women.

Protein World sells a wide range of supplements. The protein supplements such as whey protein concentrates are still a major part of the product range but now there are also general weight loss supplements that are not necessarily protein derived such as Hunger Buster.

Protein World recently ran into controversy following a marketing campaign that featured posters in the London Underground showing a slim woman in a bikini asking “are you beach body ready?”.

Feminists defaced the posters, with scathing comments and more than 43,000 people signed a petition calling for the ad to be removed. It has been considered as body shaming by many people.

However, all this has generated lots of free publicity for Protein World and their “beach body ready” advertising slogan has entered the public consciousness. It has become a catchphrase in some parts of the UK. Source

Protein World Hunger Buster Concerns

  • Comes with a choking risk – ensure you drink plenty of water to wash the capsules down
  • No proof that Garcinia Cambogia will be effective
  • Hunger Buster seems unlikely to live up to the “beach body ready” claims

What does Protein World Hunger Buster claim to do?

According to the product advertising, there are four key features to Protein World Hunger Buster.

  • Contributes to the maintenance of normal blood cholesterol levels
  • Konjac Glucomannan contributes to weight loss
  • Garcinia cambogia supports fat metabolism
  • Does not contain potentially harmful ingredients such as ephedrine or dinitrophenol (DNP)

The advertising claims this supplement:

Contains a unique blend of Konjac Glucomannan and garcinia cambogia, both of which are perfect for anyone looking to increase fat metabolism.

There are no links to clinical evidence to prove the claims.

Does Protein World Hunger Buster work?

Despite the one positive review, we cannot see this supplement working for most people. Going by the EFSA report, there is a lack of evidence to prove that Garcinia Cambogia really blocks carbs and increases serotonin levels in the way as described.

The problem is that Garcinia comes with a lot of hype and very little real evidence. Most testing has been carried out on animals and human testing has all shown different results. The expert opinion is that Garcinia Cambogia requires more stringent testing in order to establish the claims.

Protein World Hunger Buster Ingredients

The Protein World Hunger Buster is a weight loss supplement that primarily acts as an appetite suppressant, and may have other benefits too. Serving size is equal to two capsules.

  • Konjac Glucomannan 1000mg: Glucomannan is a fibre that is derived from the root of an Asian yam type root called Konjac. It absorbs water upon contact and becomes gel-like in consistency so it helps to fill the stomach and slows down digestion, meaning that you can go for longer before feeling hungry again. Numerous studies show the use of Glucomannan leads to weight loss. According to the European Food Standards Agency, a cause and effect relationship has been established between the consumption of Glucomannan and the reduction of body weight in the context of an energy-restricted diet. The panel of experts considered that in order to obtain the claimed effect, at least 3 g of Glucomannan should be consumed daily in three doses of at least 1 g each, together with 1-2 glasses of water before meals, in the context of an energy-restricted diet.

  • Garcinia Cambogia (400mg): According to studies on rats, HCA inhibits an enzyme called Citrate Lyase making it hard for the body to produce fat from carbohydrates. Other studies show that HCA increases serotonin levels so may lead to reduced appetite and food cravings. The downside is that the same effects have not been observed in humans. According to the Journal of Obesity, Garcinia may generate some weight loss initially but the effect is so small it is not significantly proven. In one test on 135 overweight subjects, the conclusion was that “Garcinia Cambogia failed to produce significant weight loss and fat mass loss” Source

So What Does All This Mean?

Glucomannan comes with some evidence that it works, the recommended daily amount is 3000mg and the daily serving of Protein World Hunger Buster adds up to 4000mg. This is if you take three servings (six capsules) a day.

Garcinia Cambogia remains unproven and requires further evidence. It may do something but according to most research, weight loss is insignificant.

We feel that if you are relying on Protein World Hunger Buster to get beach body ready, you could be in for a disappointment as weight loss will not happen overnight.

Protein World Hunger Buster Side Effects

There may be side effects. Protein World warn against choking – a known side effect to taking Glucomannan

Warning of choking to be given for people with swallowing difficulties or when ingesting with inadequate fluid intake – advice on taking with plenty of water to ensure substance reaches stomach.

This point is very important. You will need to take the capsules with plenty of water to ensure you wash them down to your stomach where they can expand in safety.

Other side effects may include:

  • Nausea
  • Headaches
  • Digestive tract discomfort

Caution: Not suitable for individuals under 18. Avoid if you are pregnant or breastfeeding. Do not take if you have swallowing difficulties. Seek the advice of your doctor if you have any health issues or are taking medication in case of interactions. Glucomannan can affect blood sugar levels so if you are diabetic get some advice from your doctor first.

Protein World Hunger Buster Customer Feedback

Protein World Hunger Buster has a lot of customer reviews over a range of online retailers.

One satisfied customer has reviewed Hunger Buster on the Superdrug website:

I bought Protein World Hunger Buster Capsules as a last resort. I needed to lose the extra pounds I had gained over the Christmas period. I really did not expect to see any good results, but I did! Two capsules about an hour before meals, taken with plenty of water, and I noticed results from the second day. I am a very happy dieter and will be buying these capsules again.

Several customers had some issues with the capsule size:

Be warned these pills are massive. And wuite difficult to swallow if you don’t usually take pills but I find they do work if you have a good diet and drink loads of water. Even 3litres a day

These are hard to swollow. They are huge. But they work!

Overall, most people seem to be happy with this supplement!

I have been using this in conjunction with 5:2 dieting. It’s brilliant. No hunger pangs at all! I can’t believe how easy it is. Lost 2lb the first week eating normally the rest of the week. Took two before we went out to dinner with friends and found I just ate smaller portions.

Watchdog Verdict

Since the Beach Body controversy, Protein World has become a well-known brand, and Hunger Buster seems likely to be effective. Although, despite there being more than the recommended serving size of Glucomannan, Garcinia Cambogia comes with very little evidence and is essentially unproven to work.

We like that side effects seem unlikely, although we are slightly concerned about the choking risk posed by Glucomannan. However, it should not be a problem if you take the capsules with plenty of water as the product information advises.

This supplement is pretty inconvenient. Take as recommended and at 6 capsules a day you will soon run through your 90 capsule bottle. In addition, do you really want to take so many pills each day? Some people will struggle with this.

In our opinion, this supplement has some good points, and could very well help you with weight loss if you can manage taking several capsules a day.
