Do Thermogenic Fat Burners Work: What You Need to Know

Do you want to burn calories without spending hours in the gym? In this case, you may consider using fat burner supplements to eliminate stubborn body fat and boost metabolism.

There are many fat-burning supplements available, and they fall into different categories. One common type of fat burner works by accelerating the natural process of burning fat, and they are called thermogenic fat burners. These weight loss supplements are designed to increase the metabolic processes that can naturally burn fat in the body.

Most of the ingredients of these supplements come from natural sources, which contain chemicals to enhance the physiological process of burning fat. On the other hand, fat burner supplement manufacturers claim that these products will help burn fat and lose weight, but there are no clinical studies for this claim yet. In fact, they are not registered with the Food and Drug Administration (FDA).

To know more about thermogenic supplements, how they work, possible side effects, and many more, keep reading below!

What is Thermogenic Fat Burner?

As mentioned above, a thermogenic supplement uses the thermogenic process for heat production. Therefore, when your body burns calories, your metabolism will produce heat from within, which requires calories as a fuel source. 

In short, thermogenic fat burners are supplements that can enhance the metabolism, which causes it to speed up and become more efficient in the weight loss journey.

According to research, some chemicals found in food and drinks contain properties that increase thermogenesis. This has led to insights into the benefits of thermogenic fat burners as supplements that promote weight loss and support fat loss.

In a wellness and fitness article written by Erik Pham, a Health Editor, thermogenic supplements usually contain natural fat-burning products that can be found at home. For instance, the coffee you drink every morning contains caffeine. The caffeine consumed helps burn fat cells and increase fat oxidation. Moreover, the buzz from caffeine stimulates your fat metabolism and gives extra energy expenditure for an intense workout.

Do Thermogenic Fat Burners Work?

You might be wondering, do weight loss pills work? The answer could be, perhaps. However, don’t expect that it can make the body fat instantly melt. The way thermogenic fat burners work depends on the type of fat burners you use. Keep in mind that fat burners do not work the same as appetite suppressants or are not some diet pills. 

However, some thermogenic fat burners contain chemicals that can suppress appetite to enhance the fat burner’s effectiveness. Here are some of the active ingredients of thermogenic fat burners that help lose some body weight:

  • Green tea extract

Green tea contains caffeine and epigallocatechin gallate (EGCG) that have thermogenic effects. It has been well-documented from that caffeinated green tea supplements can increase the metabolism by 4% and increase fat burning by 16% after ingestion.

  • Capsaicin

Like caffeine, capsaicin can speed up metabolism, which helps the body to burn more body fat and calories. In a study, capsaicin supplements can boost metabolism, leading to significant weight loss over time.

  • Garcinia Cambogia

Garcinia cambogia is a tropical fruit often incorporated in weight loss supplements. It contains a compound called hydroxycitric acid (HCA) that can block enzyme activities in fat storage and forming body fat.

  • Caffeine

Caffeine is natural fat burner found in different sources, such as coffee, tea, cocoa, and many more. It is a stimulant that boosts metabolism and stimulates the release of fatty acids into the bloodstream, where they can be used by your cells.

  • Yohimbine

It is a chemical compound extracted from the bark of African yohimbe tree. This compound has been found in many weight-loss supplements but there’s limited research on it.

The mechanism of action of thermogenic fat burners can be summed up into two points. First, they increase metabolism, then second, they provide extra energy so that you can work out at a more intense level and do the work of reducing belly fat and losing weight.

Despite containing plant sources, which makes them natural fat burners, they are no substitute for exercise. The effectiveness of fat burners toward a healthy weight is a combination of a healthy diet and exercise.

Before taking fat burners, here are the pros and cons that you should consider:

Benefits and Possible Side Effects

Like any other supplements, they come with health benefits and side effects; this is the same with thermogenic fat burners. The benefits of using this supplement can be summed up into three things:

  • Increase metabolic rate that generates heat so that you burn more calories.
  • Lessen the amount of the fat that your body absorbs
  • Suppress the appetite so that you only consume fewer 

Since the Food and Drug Administration does not regulate them, you cannot guarantee their safety. People tolerate thermogenic supplements despite all sorts of claims, so make sure to talk to your physician or pharmacist if you’re suitable to take these supplements based on your age, body composition, health condition, and many more.

Meanwhile, here are the common side effects that are associated with the stimulant component of thermogenic fat burners:

  • Elevated blood pressure
  • Anxiety
  • Agitation
  • Increase heart rate
  • Upset stomach
  • Headaches
  • Insomnia
  • Restlessness

What’s The Difference Between Thermogenic vs Fat Burners?

The main difference between thermogenic and fat burners is their mechanism of losing fat. Thermogenic works by speeding up the metabolic rate and burning calories by generating heat under thermogenesis, while fat burners directly target fat cells.

Nevertheless, they are both helpful toward your weight loss journey and are not diet pills! Whatever you choose, you should add them to your diet and exercise program to get the best results.


Thermogenic supplements can be a safe way of losing weight and burning fats as long as you take them as directed by your physician and pharmacist. Combine them with a well-balanced diet and healthy exercise program for effective benefits.

As a piece of advice, take a small amount first, then observe how this supplement affects you. Always speak to your doctor before trying any supplement because it can cause severe complications if taken carelessly.
