Throughout the world of sports and fitness, athletes and hobbyists alike regularly enjoy a range of supplements, including vitamins, proteins, nootropics, and of course, fat burners.
Put simply, fat burners are a type of supplement that specifically targets and supports the body’s metabolism to spur it into life and to help reduce the amount of fat absorbed throughout the day.
Generally, fat burners come in capsule form and are taken at regular periods, although some are also available as a pre-workout supplement.
It’s important to remember, however, that fat burners are not magic solutions that will help you lose weight. You will need to enjoy them with a healthy diet and a consistent exercise regime.
How Do Fat Burners Work?
To understand how fat burners work, you need to know that there are two different kinds of fat cells in the human body:
white fat cells, and
thermogenic fat cells.
White fat cells store energy and transmit hormones when the body sends nutritional signals, while on the other hand, thermogenic cells help to defend the body against obesity.
The latter also helps the body resist hypothermia during extreme environmental conditions.
Fat burners target thermogenic fat cells, and a process called Lipolysis can also help burn fat cells. This is when fats (or lipids) are broken down through hydrolysis, which helps the energy within fat cells fuel the body.
With this specific process in mind, fat burners are designed to increase metabolism so that the body creates more energy through sourcing stored fats and energy.
When it comes down to it, fat burners are the gear sticks to the metabolism that switches the body into a higher-order so that it burns more calories during and around exercise.
Introducing The Best Fat Burner Supplements for 2020
Now that you know all about fat burners, how they can support your fitness goals, and how they work, it’s time to see which fat burners could be best suited for you.
It goes without saying that on the market, there is a wide range of fat burners designed and produced by fitness manufacturers, which means that it’s important to know which ones are worth spending your hard-earned money on.
So, let’s take a look at some of the best fat burners for 2020.
Referred to by some as the Mike Tyson of fat burners, Instant Knockout sits on the cheaper end of the fat burner scale but is one openly used and promoted by an array of MMA fighters.

Praised within fitness forums across the internet, Phen375 is branded as one of the more blatant products on the market, which offers to help you become a “slimmer” and “sexier” you.
Like many fat burners, it works to increase your metabolic rate, boost your energy, and suppress food cravings when taken as part of a healthy diet and exercise regime.
On the face of it, Phen375 is a pretty standard fat burner, but it is one that is incredibly popular and receives rave reviews across the internet, so let’s take a look and see what’s inside.
Chromium Picolinate: Also found in PhenQ, Chromium Picolinate is a welcome addition to the burner and serves as a cofactor to specific metabolic enzymes. In layman’s terms, this prolongs the fat burning process.
Citrus Aurantium 10% TRIT: A natural alternative to synephrine, this ingredient works by boosting a specific hormone to trigger a fat breakdown in the body. At the same time, it also boosts energy, which is great for when you are adhering to a healthy exercise regime.
Cayenne powder: A pretty standard addition to any fat burner, but one that helps boost your metabolism and heats your body to break down fat in the form of thermogenesis.
Calcium (Carbonate): An interesting addition, as it is, to be honest, simply chalk. That said it is a great bulking agent, which is great if you’re looking to increase muscle mass or you are partaking in strength training.
How to take it
The product’s website doesn’t state how you should take Phen375, and its FAQs page simply discusses shipping and billing, which is not helpful.
The blog does have a few nice articles on exercise and healthy eating though. We’d advise that you take this fat burner once per day alongside a healthy meal.
The ingredients are creative enough and are sure to “do the job” with a balanced diet and exercise. The addition of calcium (carbonate) is great for if you’re looking to bulk up. You can enjoy great offers on the website.
A few people have complained about jitters, headaches and upset stomachs as part of the side effects. We don’t really know how much or when you are supposed to take the supplement.
Where can you buy Phen375?
Like all trusted supplements, you can only buy Phen375 directly from its website, although it does have some great deals on offer.
You can enjoy a single bottle for $65.95/£49.46, or enjoy two (plus a third free) for $131.90/£98.93.
If you’re looking to use the supplement in the long-term, you can make BIG savings with a four-bottle deal (plus one free) for $187.96/£140.97, which gives you saving in the region of $261.99/£197.
Phen375 doesn’t pretend to be an ultimate diet solution or even a higher-brow and unique fat burner, which is good, because it isn’t.
We have no doubt, however, that it is a good supplement for helping you to achieve your fitness goals, especially if they happen to be based around strength training or bulking.
The reason for this, however, is that the burner has been designed so that you take three capsules with breakfast and two later in the day with another meal.
A bottle, therefore, should last you a good month.
Widely available. Well-known brand. Affordable at $35 for 150 capsules. Stimulant free.
Misses favourite ingredients. Varied reviews across the internet.
Phoenix fat burner is a good product that is sure to get you closer to your fitness goals at a fair price. That said, there could be other burners on the market that offer a better product, so ensure to read through our entire list so that you get the product that is best for you.

What to Watch Out For (and Avoid) With Fat Burners
Like any fitness supplement, you need to ensure that you’re buying the best products for your personal fitness goals.
Magic formulas don’t exist
Secret recipes and magic solutions are (combined) the number one claims to avoid. Any product that makes such claims is likely to be ineffective, and if you’re unsure about any brand, always check online for customer reviews.
Check for a fully dosed formula
Fat burners that require you to take a few capsules a day are ones to look out for as it means that the supplements provide multiple but steady dosing to deliver the ingredients on the label.
Avoid proprietary blends
A proprietary blend is when a manufacturer does not disclose the dosage of individual capsules. Instead, you are likely to see a “general” blend on the label.
Unfortunately, this means that you have no idea what you’re getting in each dose, so always make sure to check the label carefully.
Seek brand names
Typically (but not always), the best fat burners are only available from the brands that design and manufacture them themselves; so, this tends to be a sign of a good transparent product from a company that cares.
When it comes to prices, you shouldn’t find anything above the $50 range (at the very most), and take great care on fat burners below $20 when bought in bulk.
Best Fat Burner Ingredients
Every fat burner will have its own specially designed blend of ingredients, and some fat burners will exhibit a good mix, while others might leave key additions, so it’s always best to research every burner.
Here is a list of quality ingredients found in many quality fat burners.
Green tea extract
Research has shown that regular consumption of green tea can help with fat loss, so this is a key ingredient in many fat burners.
Additionally, green tea also contains polyphenols, which are themselves composed of catechins and provide a variety of benefits for the body including:
Fighting and eliminating cancer-causing free radicals.
Reducing the build-up of plaque within veins.
Reducing the chance of blood clots.
Green coffee bean extract
A supplement extracted from (you might have guessed it) green coffee beans, this extract is loaded with antioxidants, including Chlorogenic Acid — an element that is mostly removed when coffee beans are roasted.
Green coffee bean extract can provide a range of benefits, including:
Promoting weight loss.
Lowering blood pressure.
Aiding the fight against Type 2 Diabetes.
Some form of chili pepper is often found in the best fat burners in the form of capsaicin, which is the element of the pepper that does the fat burning work for you.
Capsaicin has been shown to provide a range of benefits, including:
Increasing the body’s ability to burn calories.
Turmeric is a dark yellow spice that is taken from the root of a plant.
As well as adding flavor to food, it is a regular addition to fat burners as it creates metabolic heat and is high in fiber.
Another bonus is the fact that it contains a range of essential vitamins and minerals.
It can also help to:
Improve heart health.
Reduce arthritis pain and swelling.
White kidney bean
Mainly composed of carbohydrates and fiber, white kidney beans are also a great source of protein, which is especially helpful if you’re looking to build muscle mass.
An ingredient that isn’t always in fat burners, it does, however, provide a range of interesting benefits, including:
Aiding weight loss.
Inhibiting starch consumption
Promoting colon health.
Improving blood sugar control.
Glucomannan is a dietary fiber derived from the root of a konjac plant and is used in a variety of supplements, including many fat burners.
It is of benefit in a variety of ways, including:
Aiding weight loss efforts.
Improving cholesterol levels.
Reducing blood sugar levels.
For those wanting to look their best, it is also known for promoting healthy skin.
An amino acid, L-Theanine, is a welcome addition to many fat burners and was discovered as a constituent of green tea in 1949.
The acid has been shown to have a range of beneficial effects on the body:
Improved mental focus.
Aiding weight loss.
Boosting the immune system.
A relatively recent discovery, the ingredient has so far been added to a select number of fat burners.
Another spice, Cardamom, is traditionally used to treat digestive issues, although in recent years, it has been used to help people regulate their weight.
Some of its many benefits that you can enjoy include:
Increased brain function.
Reducing sugar cravings.
Freshening breath (really)
