The Science Behind Thermogenics: Do They Work for Weight Loss?

April 11. 2023

When striving to lose body fat, most individuals find reducing their calorie intake doable; many great diets meet even the most particular and unique needs. However, finding time, motivation, and energy to exercise is what people often find challenging. That is why many individuals trying to lose weight turn to thermogenic fat burners to boost their journey. Thermogenics do the hard work of burning the stored fat in your body and enhancing your weight loss efforts.

If thermogenic fat burners do the hard fat-burning work for you, who would want to include them on their weight loss must-have list? Well, about 15% of the U.S. adult population has used fat burner weight-loss supplements at some point in their lives. The truth is that thermogenics do much more for you than burn calories; they increase your resting metabolic rate and provide extra energy. However, thermogenics are often criticized by people that claim they are not as effective as most say. Those statements usually come from misunderstanding and misuse of these fat burner supplements.

Thermogenics fat burnets are one of the most popular choices for people aiming to lose weight. Are you thinking about giving thermogenics a try? Today, our weight loss clinic in Chicago experts want to discuss these supplements further so you can make an informed decision.

What are thermogenic fat burner supplements?

Let’s begin by explaining thermogenics for those who aren’t familiar with them. Essentially, therm means a unit of heat, and thermo- defines anything related to heat. Thermogenics refers to the ability or the tendency to produce heat. And if you are wondering, what does all that have to do with weight loss? Well – to burn calories, our metabolism generates heat from within; this process is known as thermogenesis. Think about how your body reacts when you engage in intense workouts, such as strength training exercises – our bodies tend to get warmer.

The faster your metabolism, the more calories it will burn. And the more calories you burn, the quicker you lose weight. Studies show that certain foods and chemical components contain properties that can induce and accelerate the thermogenesis process. Methionine inositol choline injections or pills are one example of this. Methionine, inositol, and choline are three essential nutrients that can help boost metabolism and are part of most fat burners. Typically, thermogenic fat burners include natural ingredients that you can find in your own kitchen. And besides those common ingredients, they often contain a number of chemicals or essential nutrients to enhance the fat burner’s effectiveness.

Thermogenic fat burner supplements contain ingredients that help speed up your metabolism, making it more efficient. Besides speeding up your basal metabolic rate, those fat burners can also increase your energy levels and provide appetite suppressant benefits. A great example of thermogenics weight-loss pills is Lipo Re-Ignite®, which contains 2 of the essential nutrients mentioned above – inositol and choline.

How do thermogenics work?

Now you know that thermogenic fat burners help boost your metabolism and that a fast metabolic rate means greater and faster weight loss. But how do thermogenics work in your body to help you achieve that? The short answer would be that fat burners work by boosting your blood pressure; this slightly increases your body temperature, which augments your overall energy expenditure leading to weight loss.

However, there is a wide range of thermogenic fat burners (we will comment on the most popular ones below). Some of them only help with fat burning by boosting your metabolism; others also promote appetite suppression, just like Phentermine for weight loss. How fat burners work often depends on the particular ingredients they contain. For instance, certain thermogenic supplements’ ingredients act directly on the central nervous system of your brain. An example of this would be caffeine – a stimulant found in coffee beans and green tea drinks known for its metabolism-boosting properties.

But as mentioned, there are many types of thermogenics supplements, and not all of them work as stimulants. Others promote weight loss by working at a molecular level and inhibiting or synergizing with chemicals that regulate fat storage (lipogenesis) and fat breakdown (lipolysis).

Benefits of thermogenic fat burners

From what we have discussed so far, we can say that thermogenic fat burners present far more advantages than helping you burn calories. To better understand all the pros you can get from different weight loss supplements, here are the primary benefits of using thermogenics to reduce body fat:

  • Appetite suppression – like with prescription weight loss medications, such as Ozempic weight loss
  • Increased resting metabolic rate
  • Faster fatty acid metabolism
  • Increased energy levels – which means more energy for your workouts and more calory burning
  • Enhanced use of fat for energy – say goodbye to stubborn fat

Of course, the benefits will depend on which thermogenic supplement you choose. For example, Lipo C injections will help you burn stored fat and boost your energy, among other health benefits.

Most popular thermogenic supplements for weight loss

When people hear or read the word: thermogenic, they often think about complex and complicated procedures. But as we clarified before, typically, these supplements are made with natural ingredients that we all know about. Those elements are usually combined with essential nutrients such as vitamins, folic acids, or chemicals such as carnitine vs. creatine.

Here are some of the most popular thermogenic supplements, their benefits, and how they work:


Caffeine is the most commonly used ingredient in thermogenic supplements and also the most well-known one. Almost everybody has had a cup of coffee before – and remember that caffeine is also found in some tea leaves, energy drinks, and sodas. So most individuals are familiar with caffeine and its many uses and benefits – appetite suppression among them. This ingredient is a stimulant drug; it can promote a metabolism boost, increase energy levels, and make you more alert. Besides fat burners, caffeine is also the primary ingredient of pre-workouts.

Why is caffeine considered thermogenic? Because it increases your body’s adrenaline levels. Adrenaline is a hormone responsible for making fat cells release fatty acids, so your cells can use them for energy. In turn, this process increases your metabolic output, leading you to burn more calories.

Green tea

Green tea supplements are also trending among individuals trying to lose weight. The beverage is well-known for its antioxidant properties and for being a source of vitamin C and probiotics. This tea has two thermogenic components: caffeine and epigallocatechin gallate, EGCG for short. The combination of these two elements has fat-burning and metabolism-boosting potential.

The EGCG compound is commonly found in teas and tends to receive a lot of attention for its positive impacts on our health. What this compound does when you take it through thermogenic supplements is enhance the effects of caffeine by slowing down the speed at which adrenaline breaks down. Supplements that contain green tea extract increase your metabolism by 4% and fat-burning ability by 16%.


Capsaicin could be a brand-new word for most individuals. It is the ingredient in hot chili peppers that makes them hot. It is the responsible element for your sweating after having a very spicy pepper meal. As we mentioned, some of the most common thermogenics are foods or ingredients you probably have in your kitchen. But sometimes, it’s more manageable to consume capsaicin through weight loss supplements than by eating a considerable amount of chili peppers.

Capsaicin has almost exactly the same effect as caffeine; it induces adrenaline, accelerating your metabolism. It also has appetite suppressant effects, making it a double weapon against weight gain and fat.

Blended combinations

There are more thermogenics to include on this list, but caffeine, green tea, and capsaicin are the most popular ones. However, the best thermogenic fat burner supplements often include a blend of these ingredients, among other nutrients and chemicals, to boost their weight loss efficacy. Lipo Re-Ignite SL® Spray, for example, has coffee bean extract as one of its many fat-burning ingredients. What makes this spray a powerful weapon against stubborn fat? It combines coffee extract, vitamins, and other healthy nutrients.

Are thermogenic fat burners safe?

Besides how do thermogenics work, many people come to us asking if these weight-loss supplements are safe. As you may know, thermogenic products do not require a prescription from a healthcare professional; they are very accessible. So are fat burners safe for your health? Thermogenics are proven to be safe; data from different studies support most of the ingredients included in these supplements. However, it is required to examine each particular supplement to determine how safe and effective a product actually is. While most contain some of the popular ingredients we mentioned, such as vitamins to boost metabolism, others could include dangerous or non-tested ingredients. Always check the ingredients label carefully and opt for thermogenic fat burners that use safe chemicals.

Like most supplements, thermogenics can cause some side effects. The most severe one is allergic reactions; fortunately, if you check the ingredient list, this adverse effect can be avoided. If you are allergic to one of the chemical components, look for a fat burner that uses other essential nutrients. Being highly sensitive to caffeine could be another issue that is also easy to avoid; choose a supplement that does not contain caffeine. Some of the most common side effects of thermogenic fat burners are headache, nausea, stomach upset, constipation, dehydration, insomnia, and anxiety. These supplements can also cause irregular heartbeat and high blood pressure.

The best option is to go for thermogenic supplements recommended by weight loss professionals to guarantee both efficiency and safety. And to ensure you stay healthy and prevent side effects, you must always follow the recommended dosage.

Do thermogenics actually work for weight loss?

Thermogenics fat burners have been around for a long time now. Nevertheless, there is still a lot of skepticism surrounding these supplements. Most people who are new to using these weight loss aiders ask themselves: do thermogenics actually work? Can fat burners help me lose weight fast? The answer is yes; thermogenics do work and will lead you to your weight goals.

However, it’s essential to understand how thermogenics assist your fat loss efforts. Despite their name, these supplements do not directly burn fat. Instead, they speed up your metabolism, which makes you burn more calories faster. Therefore, thermogenics can indirectly – but effectively – help you burn fat and lose those extra pounds.

Keep in mind that these thermogenic supplements are meant to boost your journey; you must complement your weight loss efforts with a proper diet and regular exercise. Some patients often wonder: Should I take fat burners on non-workout days? Absolutely yes! Since you will also get an extra kick of energy thanks to the fat burners, you will be able to endure longer workouts and burn more fat.
