We found some good reviews of Protein World’s product online. It seems to be a well-reviewed supplement.
One user said that they noticed a big increase in their energy levels and also reported that it helped them with digestion. Someone else said that the capsules were “amazing” and that they’d continue to take them.
Overall, Instant Knockout takes this round. It’s clearly one of the market leaders when it comes to fat burners and customers seem to love this product. We found countless positive reviews online when doing our research.
Instant Knockout: 1 | Protein World Fat Metaboliser: 0
If you’re looking to find out quickly whether a fat burner supplement is going to be effective, one good clue can often be found in the serving frequency.
In order to give your body the necessary nutrients it needs to burn fat, you need to be supplying the ingredients as regularly as possible. That usually means that the more often you take the product in one day, the better.
Each bottle of Instant Knockout contains 120 capsules, which is one month’s supply of four per day.
With Instant Knockout, you take one capsule, four times per day, in between meals.
Each bottle of Protein World Fat Metaboliser Capsules contains 90 capsules, which is around 22 days’ worth if you stick to the maximum recommended dose of four per day.
With the Fat Metaboliser Capsules, you take 1-2 capsules, a maximum of twice per day. They recommend that you stick to one capsule per serving for the first week, before stepping it up to two after that.
The other thing to remember with both of these products is that because they contain significant amounts of caffeine, we wouldn’t recommend taking them too close to bedtime.
We’re going to give this round to Instant Knockout as well. We were slightly confused by Protein World’s instructions and we prefer the simplicity of just taking one capsule four times a day with Instant Knockout.
Instant Knockout: 2 | Protein World Fat Metaboliser: 0
Next up is the all important ingredients. Do these products really contain the right things to help your body to burn more fat?
Let’s kick things off with a comparison of the full ingredients lists of both products:
There are some of our favorite ingredients for fat burning in both of these products. Here’s our summary of the top picks from both supplements:
Instant Knockout’s top ingredients:
• Caffeine Anhydrous – Energy and metabolism booster
• Green Tea Extract – Natural thermogenic
• Cayenne Powder – Thermogenic and appetite suppressant
• Green Coffee Bean Extract – Thermogenic
• Glucomannan – Our favourite natural appetite suppressant
• Chromium – Boosts metabolism
• Black Pepper Extract – Absorption of ingredients
Protein World Fat Metaboliser Capsules top ingredients:
• Caffeine Anhydrous – Energy and metabolism booster
• Green Tea Extract – Thermogenic and endurance
• Cayenne Pepper – Raises core temperature and suppresses cravings
As you can see from the above, Instant Knockout contains many more of our favorite fat burning ingredients than Protein World’s Fat Metabolisers.
It was really a shame not to see things like Green Coffee Bean and Glucomannan in Protein World’s product, although Caffeine, Green Tea and Cayenne Pepper are all solid ingredients.
The main issue with have with Protein World’s offering is that each capsule contains quite a lot of caffeine (100mg per capsule). We don’t like to see fat burners overloaded with stimulants, and Instant Knockout has slightly less at 75mg of caffeine per capsule.
We’re going to give this round to Instant Knockout as well, taking into account all of the above.
Instant Knockout: 3 | Protein World Fat Metaboliser: 0
You’ll want to be sure that the product you’re taking is completely safe.
Fortunately most of the natural fat burners on sale these days contain pretty safe ingredients.
The one thing to look out for is the stimulant content. We found lots of products these days have way too much caffeine in them.
Instant Knockout and Protein World’s Fat Metaboliser Capsules fare pretty well in this category.
As we mentioned above, Instant Knockout contains 75mg of caffeine per capsule, while Protein World’s Fat Metaboliser Capsules contain 100mg.
That’s also not taking into account the fact that Protein World’s product also contains 75mg of Guarana per capsules, which is another caffeine-like stimulant.
The less stimulants the better in our opinion, and so we’re going to give this round to Instant Knockout as well.
Instant Knockout: 4 | Protein World Fat Metaboliser: 0
The final category for comparison is the price tag. Which is the cheaper supplement and which offers the more servings for your money?
Protein World Fat Metaboliser Capsules is currently priced at $38 / £22 / €34 per bottle and you can buy it from the official website and via some other online retailers.
Clearly, Protein World’s product is cheaper than Instant Knockout, which is regarded as one of the more premium-priced products out there at the moment.
The only way Instant Knockout can compete in terms of price is via the multi-box deals on the official website, where you buy three bottles and get a fourth free. The deal includes free worldwide shipping.
However, this round certainly goes to Protein World thanks to its cheaper price-tag.
Instant Knockout: 4 | Protein World Fat Metaboliser: 1
So, there we have it – we’ve picked Instant Knockout as the clear winner of the fat burner battle when put up against Protein World’s Fat Metaboliser capsules.
Both of these products are popular fat burners but we’ve sided with Instant Knockout because we think that it’s a more well-rounded product than Protein World’s offering.
Protein World’s Fat Metaboliser Capsules do contain some good ingredients but Instant Knockout is the better product in our opinion.
