Backed up by the latest research, there are plenty of supplements which only use natural ingredients to help you burn fat more quickly.
Most of the top products on sale these days also include natural stimulants to help keep your energy levels up, making your workouts more productive.
Health and fitness supplements sometimes get a bad rep because they’re often seen to be an unnatural way to accelerate your results. And that’s a shame, because most of the top products on the market today are actually made using only natural ingredients.
In short, fat burners work by boosting your body’s natural ability to burn fat. Your body is actually a fat burning machine and it has evolved over millions of years to burn fat effectively and use it as a source of energy.
Unfortunately, modern-day society has prompted the rise of mass-produced unhealthy foods, causing a spike in obesity levels worldwide.
The best fat burners work by giving your body the fuel it needs to step up its natural ability to burn fat and therefore speed up the process of getting lean.
You’ll want to make sure that the product you choose contains only natural ingredients. We want to avoid any nasty artificial sweeteners or colourings.
Some of the best ingredients for a natural fat burner include:
Green Tea Extract
Green Coffee Bean Extract
Black Pepper Extract
The dosage varies from product to product but generally you’re encouraged to take a fat burner at regular intervals throughout the day to keep your metabolic rate as high as possible.
That being said, most good fat burners contain caffeine or similar stimulants, meaning that it’s best to avoid taking them too late in the day so that they don’t affect your sleep.
So, with all of the basics out of the way, we’re now going to take a look through our pick of the top 10 natural fat burners with energy on sale today. We’ve trawled through the latest research and studies to compile this list of the top products we think are most effective at burning fat in a natural way.
This product is at the top of our list because it contains some of the best natural fat burning ingredients and also has great customer reviews. Instant knockout is made by specialist supplements company Roar Ambition and it’s one of the best-selling fat burners on sale right now.
It was originally developed to help professional boxers and UFC fighters strip fat before a big fight but was made available to the general public a number of years ago.
We’ve done the research and we haven’t been able to find a product on sale right now with an ingredient profile as good as Instant Knockout.
Instant Knockout contains both Green Tea extract and Cayenne Pepper, which are two of the best natural fat burners out there. It also contains a healthy dose of Caffeine Anhydrous and Green Coffee extract, which help to speed up your metabolism and keep your energy levels up during your workouts and throughout the day. Also included in the main stack are Zinc, Vitamins B6 and B12 and Piperine, which helps to ensure that all of the ingredients are absorbed properly.
You can only buy it on the official website, meaning that you won’t find it at other stores such as Amazon or eBay. The capsules of this supplement contain gelatin, making it not suitable for vegetarians.
This is a great product and contains the best ingredients, and judging by the thousands of positive reviews online, customers seem to think so too.
While doing our research to pick the best fat burners, we found that most products were aimed at guys rather than girls. So we did a little digging for some products directly targeted at women and came across Leanbean.
Leanbean is made by supplement company Ultimate Life and despite being quite a new product, has already proven very popular.
This is a very impressive new product and is definitely our top pick for women looking to get lean quickly.
This product contains some great natural fat burning ingredients such as Glucomannan, Green Tea Extract, Tumeric and Raspberry Keytones. Like most of the best supplements on sale today, Leanbean also contains Piperine (from black pepper) to help increase the absorption of the ingredients.
It’s a little bit on the pricey side but the premium ingredients make it worth it in our opinion. You can only buy it directly on the official website right now.
This is definitely our top pick for a fat burner for women. It contains some of the best ingredients around and it’s refreshing to find such a quality product available for females.
Next on our list is Protein World’s main fat burner product. Their Fat Metaboliser Capsules (previously called Fat Melter Capsules) are one of their most popular products for people looking to shed those final few pounds and get as lean as possible.
We’ve broken down the ingredients and this is a pretty solid product if you’re looking to boost your body’s natural ability to burn fat.
This product contains the two most important natural ingredients for burning fat (in our opinion) – Cayenne Pepper and Green Tea. It also includes 126mg of Caffeine per capsule, meaning that you’re going to feel energised while taking this supplement.
It’s a premium-priced product, meaning it may not fit into everyone’s budget. The caffeine conte may also be a little too high for some people – there are warnings on the website about this and it could affect your energy levels.
This is another popular premium-priced product but the high caffeine levels may affect some people.
Next up on our list is Thermopure, which is made by specialist health and fitness company Myprotein. They are famous for their various protein powders and other offerings and their products are generally well reviewed.
We’ve taken a closer look at the actual ingredients in this product and here’s what we found.
Like all of our favorite fat burners, Thermopure contains Green Tea extract to help boost your metabolism and boost your body’s natural fat burning ability. It also contains Raspberry Ketones, which have been linked with helping to increase the release of stored fat in the body.
We were disappointed not to see Cayenne Pepper included on the list of ingredients. It’s a shame because it’s one of the best natural fat burning ingredients around these days. It’s a slightly cheaper product than man of them of this list and so the ingredients are not quite as premium as some of the others.
Bottom line: This is a good product for those on a budget, but there’s a slight compromise in quality with the ingredients.
Next up is Cutting Edge, made by Bulk Powders. They’re a reputable UK-based health and fitness company known for their cut-price protein powders. Cutting Edge is billed as a very strong fat burner, so let’s take a closer look at some of the specific ingredients in this product.
Green Coffee Extract and Caffeine mark the main sources of energy in this fat burner. As for the fat burning ingredients themselves, Cutting Edge uses an interesting blend of Cinnamon Extract, Peppermint Leaf Powder and Choline Bitartrate. It also includes BioPerine® to help increase the absorption of the other ingredients.
Doesn’t contain one of our favorite fat burning ingredients – Cayenne Pepper. (At the risk of repeating ourselves, Cayenne Pepper should really be one of the first ingredients on your list when looking for a fat burner. It’s a great way to boost your metabolism naturally!) It’s also quite a pricey product so it might not suit everyone’s budget.
This is a solid product but some may find it a bit pricey. Also disappointing it doesn’t contain Cayenne Pepper.
Next up on our list of the best fat burners with energy is Grenade Thermo Detonator. It contains some great ingredients and comes in some very cool packaging (grenade-shaped bottle, anyone?). Let’s take a closer look at some of the key ingredients.
Like any good modern natural fat burner, Thermo Detonator contains some of the most popular ingredients, such as Caffeine, Green Tea Extract, Green Coffee and Cayenne Pepper. It also contains Bitter Orange Powder and Phenylalanine, although we’re not convinced about their fat burning properties.
This product contains some artificial colourings, which we really don’t think are necessary in a fat burner. Another slight let-down is that it doesn’t contain Black Pepper Extract to help increase the absorption of the other ingredients.
Bottom line: This is a good product featuring some of the top ingredients for burning fat but it’s also missing a couple of key things.
Next on our list is Sci-Mx Shred-X Rippedcore. This is marketed as a high-strength fat burner designed to help you shed the pounds quickly. Sci-MX are a reputable British sports supplement company and Shred-X Rippedcore is their main fat burner offering.
Shred-X Rippedcore contains Green Tea Extract and uses guarana as its main source of energy. It also contains our favorite cayenne pepper and black pepper extract to help increase the absorption of all of the separate ingredients.
We would prefer to see Green Coffee extract as a source of energy ahead of guarana but this product contains some good ingredients. It’s a premium product so may not fit into everyone’s budget and some of the ingredients are not known for their fat burning qualities.
This is a solid product from a reputable British company. It all makes for a solid fat burner with energy.
Next on our list of fat burners with energy is Adapt Nutrition’s Adapto-Lean. This particular product is marketed as a weight management supplement and is designed to keep you as lean as possible. Let’s take a closer look at the ingredients.
This product contains some great ingredients – including, Caffeine Anhydrous, Cayenne Pepper, Green Tea Extract and Green Coffee Bean. It also contains Chromium and Bitter Orange Peel to help boost its fat burning capabilities.
This is again a premium-priced product which means it may not fit into everyone’s budget. Doesn’t contain black pepper extract for increased absorption of the ingredients. If you’re not based in the UK, it may be better to buy from a company which reliably ships worldwide.
Bottom line: This is a good product and it contains some of the best proven fat burning ingredients out there.
We hadn’t come across this product before so have done some research into it. The TNT Fat Burner contains some pretty solid ingredients and seems to be widely available online. Let’s take a more detailed look at what’s in it.
TNT Fat Burner contains some good natural ingredients to help boost your fat burning ability, including Green Tea Extract, Ginger Root, Caffeine, Tyrosine and B Vitamins. Other ingredients include black pepper extract and Thiamin.
Sadly, like a handful of the products on this list, TNT Fat Burner doesn’t contain Cayenne Pepper. Its caffeine content is also pretty high at 240mg per serving, which may be uncomfortable for some people.
This is a decent fat burner but there are better products higher up on this list if you don’t want to compromise on quality with ingredients.
The final product on our list of the best fat burners with energy is Thermo Cuts by Optimum Nutrition. You’ve probably already heard about Optimum Nutrition as they are one of the leading supplement and health and fitness companies around.
Caffeine, Cayenne Pepper, Green Tea Extract, Guarana and Zinc are among the ingredients in this fat burner. It’s a good list and makes for a solid overall product. Thermo Cuts also contains Acetyl L-Carnitine and Black Pepper Extract.
The ingredients list is pretty good and contains most of the top things we like to see in a good fat burner. However, the Caffeine content of 200mg per serving (you’re supposed to take two servings per day) may be a bit high for some.
This is a good product featuring some strong ingredients. It’s a shame it doesn’t contain Green Coffee Bean and the Caffeine content may be a bit too high for some.
So there we have it, our pick of the best all natural fat burners with energy. We’ve taken you through some of the key ingredients to look out for and also selected our favorite products on sale. Instant Knockout and Leanbean definitely stand out above the rest but you won’t go too far wrong by choosing any of the products on this list.
Remember, a good fat burner can help you strip those stubborn areas of fat, but you should also make sure you’re exercising regularly and eating well. Good luck on your fat loss journey!
