What Are They?

If you don’t know what fat burners are, then it’s not a complicated concept. Simply put, they refer to any supplement or drug that has a primary effect on burning fat and improving the overall health of the person consuming them. The majority of people who use these supplements to get their health benefits and quickly lose weight use them as dietary supplements (Source).

It is also common for bodybuilders to use these supplements and drugs to get rid of their top layer of meat on your body in order to get a more aesthetically pleasing musculature and appearing ‘ripped’. However, before you dive headfirst into using these belly fat burners to get all their benefits, you should ascertain first as to whether they are actually healthy for you and also learn how they work to get rid of body fat (Source).

How Do They Work?

Most of these aids are simply drugs of the stimulant category. All this means is that these drugs work to drastically speed up your metabolism, thereby causing your body to quickly burn fat to keep your energy levels normal.

If you think stimulants are not that commonly used, then you should realize that caffeine is a stimulant. This is a substance that is used in a lot of commonly consumed drinks that people consume every day, such as coffee, tea, energy drinks, etc. Many people don’t use caffeine-containing products for their weight loss properties- you can use a weight loss calculator to figure out how much fat you should be targeting to burn. For example, a lot of people drink coffee to increase their alertness and energy levels and avoid getting lazy and lethargic.

Other people use energy drinks and coffee for the express purpose of losing body fat, as part of their dieting process. The main reason why stimulants work so well to burn your body mass is that they trigger higher levels of production of adrenaline in your body. Adrenaline is responsible for the ‘fight or flight’ instinct in all humans, and it is usually naturally produced in situations of extreme stress and causes an increase in blood pressure, heart rate and overall physical prowess and agility of your body as a response to a perceived threat. Thus, by triggering the production of adrenaline, stimulants make your body believe that it is using up a lot of energy, which causes you to lose weight at a rapid rate.

Stimulant Fat Burners vs Thermogenic Fat Burners

Substances that cause you to lose body mass and don’t have stimulant properties are alleged to work by moving most of the fat being produced in your body into natural metabolic pathways. While this might seem like a technical and complex topic, the main thing to take away is that non-stimulant supplements work only rarely and are not usually worth your money or time.

There are a category non-stimulant supplements that are called thermogenic fat burners. The main effect of these on your body is that they increase your heartbeat rate, which has the direct effect of reducing the overall mass of your body.

Although thermogenic aids work well for the purpose of losing weight, frequent and long-term use of them is not recommended because using them puts a strain on your heart. This is why you only use them rarely, and not make it the main aspect of your weight loss plan.

Common Ingredients

Now let us move on and learn about what research and science have to say about some of the most commonly used ingredients in these kinds of supplements.


CLA is an abbreviation of Conjugated Linoleic Acid. Usually, CLA is a polyunsaturated fat that is most typically found in sources of meat, such as grass-fed cows. Over the past few decades, CLA has been studied and researched by experts from all around the world and it has been proven to have significant weight reducing properties.

Green Tea

This is another commonly consumed beverage that is well known for its use as an aid in losing weight, made even more effective when it is accompanied by physical exercise. Apart from its weight reducing properties, it is also a great source of particular antioxidants that lessen your chance of getting cancer. All this means that green tea is an overall excellent beverage if you want to take good care of your health.

Black Pepper

According to research, black pepper has been proven to have properties that inhibit the development of new fat cells, which means that it can help people stay thin and lean.

L-Carnitine Tartrate

This difficult to pronounce substance is an amino acid that has been shown by research to turn fat into a source of energy and also improving the overall physical performance of the body.

Green Coffee Bean

One of the most preferred supplements to lose weight is green coffee bean extract. There has been sufficient research done on them to prove that it is an effective weight loss aid. And it is also an excellent source of cancer-fighting antioxidants. The main weight loss ingredient in green coffee bean extract is chlorogenic acid, so make sure that when you are buying this from a shop, it is 50% Chlorogenic acid.


The source of thermodiamine is an exotic fruit that is mostly only found in some regions of China. Research has shown that it increases the temperature of the body, which helps to suppress appetite and also burn more calories at a faster rate.

Garcinia Cambogia Extract

The source of this supplement for weight loss is a tropical fruit. It has become very fashionable during the past few years, although it has been shown to have only low to medium weight loss properties, as compared to most other weight loss supplements.


As mentioned before, caffeine is the most commonly consumed stimulant for burning up body fat. It boosts the production of epinephrine and norepinephrine in the body, which leads to the breaking down of fatty acids and moving them into the bloodstream and transforming the fat into sources of energy. Caffeine also has mild appetite suppressing properties.

Safety Concerns

According to some research, such as that published in the Canadian Journal of Gastroenterology, some popular weight loss aids such as green tea extract can lead to liver failure. When it comes to green tea extract, it has been showing that consuming it along with food greatly decreases the chances of any damage to your liver. Consuming the extract on an empty stomach greatly increase the chances of liver damage and or failure.

A better alternative to consuming green tea extract is to just drink plain green tea frequently, as by doing this, you will only be consuming caffeine. Keep in mind though, that consuming too much caffeine in a single day can lead to nervousness and anxiety in most people, especially when the amount of caffeine consumed increases 400 milligrams.

There are some other kinds of thermogenic weight loss aids that have been shown to have more negative side effects than green tea does. For example, bitter orange has been shown to significantly increased levels of anxiety, chest pains, and blood pressure. Another fat burner, chromium, has been shown to be the cause of hives, headaches, nausea, and vertigo.

The aforementioned CLA increases the chances of having abdominal pains, constipation, and diarrhea. Ma Huang can lead to elevated blood pressure, increased anxiety, increased risk of stroke or heart attack and increased blood pressure.
