Best Fat Burners 2021

Overview

Instant Knockout is one of the most popular supplements you’ll find online in 2021. The internet is flooded with positive reviews and customer testimonials vouching for the quality of the formula. Most reviewers say it works best as part of a healthy workout and nutrition plan.

Sold as a capsule rather than a powder, Instant Knockout boasts happy customers all over the world and continues to grow in popularity.

Like a lot of supplements, these capsules are aimed at bodybuilders and athletes. But search for reviews online, and you’ll see that men of all shapes, sizes and walks of life love Instant Knockout.

What’s in it?

Instant Knockout contains green tea and cayenne pepper – both staples of many popular fat burners. These ingredients are said to help burn more calories, which could lead to faster results. IK also contains glucomannan, a fiber which may promote fullness and reduce food cravings. These ingredients are joined by vitamin B6 and B12, GTF chromium, zinc, piperine and green coffee extract. The result? A natural supplement without any risky substances – and one that could help you achieve your goals faster.

How to take it

Each bottle of Instant Knockout contains 120 capsules. According to the manufacturer’s instructions, you’ll get best results by taking it four times a day – once in the morning, lunch, in the afternoon and before your evening meal.

Conclusion

Instant Knockout looks great – but all the signs suggest it offers much more than pretty packaging. The product can help support your training goals, boost confidence and keep you motivated for longer as part of a good diet and exercise routine. No proprietary blends and transparent formula are big bonuses and make this product stand out on our list!

Overview

Hunter Burn is described as a ‘premium’ fat burner. It’s aimed at the top end of the market and is designed for those looking for larger doses and higher quality ingredients. This comes at increased cost – but does it deliver? Hunter Burn features the largest serving sizes we’ve ever seen, while also using more potent forms of certain key ingredients. Some will want the cheapest on the market. But this is a highly-researched formula for men who are happy to pay more to get the best.

What’s in it?

Hunter Burn contains the key ingredients you’ll find in other products, but at much higher doses. For example, it contains matcha green tea, a variant of the green tea extract you find in other products. The difference is this type of green tea is three times stronger – and (in theory) it could help burn calories even faster. Hunter Burn also contains konjac root, which is said to reduce hunger. To finish off, a good dose of vitamin D3 is thought to help you lose weight, but gain muscle. The larger servings make up for the high price, giving you a range of meticulously-researched ingredients in optimal amounts.

How to take it

Each daily serving is six capsules, and there are 30 servings per container, giving you a month’s supply. The directions on the label state that you should take two capsules with a large glass of water three times a day before your main meals. As with any supplement, you’ll need to take it for a couple of months alongside a healthy fitness program and diet to give your body time to adjust. If you have any pre-existing conditions, remember to seek medical advice before taking any supplements.

Conclusion

As with any supplement, you need to make sure the ingredients are safe, natural, carefully selected and in the right amounts. Hunter Burn seems to meet these criteria and even though it costs a bit more, you seem to get what you pay for. A supplement for those who are quality conscious.

Overview

Third on our best fat burners list is Hourglass Fit, a 120 capsule fat burner which has an impressive selection of ingredients and attractive looking packaging. You might be put off by some of the more female orientated aspects of the product, including the marketing and the look of the brand, but don’t be. There’s no such thing as a gender specific fat burner. Men and women’s bodies are almost identical so there’s no reason why this product won’t work for any man. The best way to prove this is to look at the ingredients. As you’ll see, they’re common in many male targeted fat burners.

What’s in it?

Hourglass Fit contains a great ingredient portfolio, enough to stand out against many of the market leading fat burners. For instance, you’ll find a generous dose of glucomannan, a root extract that swells when it hits your stomach and stops you from getting annoying hunger cravings between meals[1]. As well as this, your appetite is kept well under control with the addition of 5-HTP. This compound is known as a natural precursor to serotonin, a brain chemical which has been shown to offset hunger-inducing hormones, helping you control your food intake[2].

Also inside is cayenne pepper, a known thermogenic that works to heat up your body, boost your metabolism and help you burn more calories in less time[3]. It also contains a range of vitamins including zinc, vitamin B6, and vitamin B12. In addition, black pepper extract ensures your body absorbs the other vital nutrients in the formula.

How to take it

Each bottle contains 120 capsules, giving you plenty of fat burning pills for a calendar month. To get the best effect you should take one capsule four times a day.

Conclusion

Hourglass Fit is a great choice for a men’s fat burner, despite being marketed at women. Ignore the packaging and look at the list of ingredients and the product. It’s clear to see the creators have put a lot of thought into this supplement, even making the capsules vegan friendly. The ingredients complement each other perfectly to target every aspect of the weight loss process.

One thing to note is that Hourglass Fit doesn’t contain any stimulants. If you struggle with motivation levels when on a low-calorie diet, the absence of a stimulant may mean Hourglass Fit won’t work for you. However, if you are sensitive to stimulants, you’ll likely get on with this supplement very well. Overall, Hourglass Fit is a fantastic product with a top selection of ingredients and we’d highly recommend it for anyone serious about buying a fat burning supplement in 2021.

Overview

Legion Athletics Phoenix is described by the manufacturer as “a 100% natural, caffeine-free fat burner”. It may help you burn fat by reducing hunger cravings and speeding up your metabolism, while also offering to raise your energy levels. In a video on the brand website, the founder states that this product could help “drive fat loss with proper dieting”. To his credit, the founder also states that Legion Phoenix will only help you achieve optimal results when you use it as part of a healthy exercise and diet plan.

What’s in it?

In this nine-ingredient formula, you will find naringin – a flavonoid said to improve lipid metabolism and fight obesity. It also features epigallocatechin gallate (ECGC), an active ingredient of green tea that has been shown to increase weight loss. Meanwhile, 5-HTP is thought to improve mood and reduce the appetite, and L-tyrosine could improve your ability to focus under the stress you may feel when cutting calories. In addition, hesperidin is said to help fight inflammation – a possible cause of weight gain, and forskolin may also help prevent obesity.

How to take it

Take three capsules with breakfast. Then, take another two capsules with either lunch or dinner. For best results, the manufacturer recommends combining Phoenix with caffeine.

Conclusion

Legion Athletics Phoenix is a very good product – and it checks most of the boxes you need from a weight-loss product. We’re not fans of ingredients like salicin, which lack the research you’d expect from a fat burner of this quality. However, Phoenix does contain ingredients which could deliver most – if not all – it promises.
