The Truth About Thermogenics: Are They Effective?

Whether you’ve been inside a supp store or checked us out online, you’ve probably seen fat burners, pre-workouts and thermogenics. The first two are pretty self-explanatory, but if you’ve found yourself wondering what an earth thermogenic is, you’re not alone.
 

While pre-workouts are taken before training to support overall energy and wellbeing, both fat burners and thermogenics are often used to support your body goals. The difference? Thermogenics and fat burners target your body goals through different methods. Both formulas contain fairly similar blueprints, but fat burners are thought to support the process by working to break fat cells down and convert them into energy. Thermogenics, in contrast, work by generating heat (a process called thermogenesis) and accelerating your metabolism (Sellers, C. 2023).

Common Myths About Thermogenics


Now, let's make one thing clear: thermogenics aren’t a magical mystery solution to fat loss. So, before we move on, let’s bust a few myths about thermogenics.


 

thermogenics work without exercise


Most people want results without the hard work, and this myth reinforces that. If you’re taking a thermogenic each day without making any lifestyle changes, you’re going to be disappointed in the results. These supplements work best when used in conjunction with a balanced diet and exercise routine (Henning, J. 2022).


 

Thermogenics Start Showing Results Immediately


No, sorry, that’s not how that works (as much as we wish it did). You’re going to need to consistently supplement with your thermogenic pre-workout while maintaining a balanced diet and exercise routine. Once you’ve built consistency, you should start to notice improvements in your performance and physique.


 

All Weight Loss Supplements Work The Same


While they all support the same goal, not all weight loss supplements work the same. Whether you’re looking at weight loss protein powder, fat burners, thermogenic pre-workouts or appetite suppressants, different supplements approach weight loss in different ways. Moreover, everyone reacts differently to these supplements. Different health conditions, hormone levels, activity levels, and dietary restrictions and preferences can all play a role in how these supplements support weight loss. These factors are key.


 

The science behind thermogenesis unpacked


Thermogenics work by inciting thermogenesis, which, as you can probably guess, is a process that produces heat naturally. This happens mainly in brown adipose tissue (BAT) and skeletal muscle but can also occur in other tissues. The sympathetic nervous system controls this process and activates certain receptors, including beta-adrenergic receptors.


The process involves the activation of beta-adrenergic receptors, with compounds like ephedrine and caffeine helping to stimulate beta-adrenergic receptors. This stimulates the release of a chemical called norepinephrine, which plays a key role in thermogenesis. The next step is to increase your metabolic rate. Norepinephrine signals different tissues in the body to speed up their metabolism, which may help you burn more calories. The most noticeable effect is in adipose tissue, where stored fat is broken down and released into the bloodstream as free fatty acids. Finally, this leads to an increase in body temperature as a result of the higher metabolic rate and the generated heat. This heat is one of the key ways that thermogenics are thought to support weight management (Frey, T. 2023).


 

Common Thermogenic Ingredients


If you managed to understand what we were talking about above, well done. Now, let’s move on to something a little easier to digest. Here are the most common thermogenic pre-workout ingredients, so if you’ve purchased a fat-burning thermogenic before, you’re probably familiar with a few of these.



caffeine


When it comes to pre-workouts, fat burners, and thermogenics, caffeine is almost always the first ingredient on the recipe card (unless you’re shopping Non-Stim). Caffeine is renowned for its support in achieving body goals. This compound supports your metabolism and may help you burn more fat during exercise. Studies demonstrate that caffeine can amplify metabolism by up to 16% for 1-2 hours. It also promotes fat utilisation as fuel, particularly in individuals with less weight. The key thing is to make sure you don’t go overboard with caffeine. Most thermogenic pre-workout supplements and energy supplements contain high doses of caffeine, so it is important to assess your tolerance. The daily recommended caffeine limit is 400mg, so as long as you’re not taking multiple thermogenic pre-workouts in a day, you should be fine (Raman, R et al. 2023). But of course, if you are sensitive to caffeine, pregnant or lactating, then this should be avoided.



green tea


Green tea is among the healthiest beverages on the planet, and as a result, it is a staple in most thermogenic pre-workout supplements. Loaded with antioxidants and healthy compounds, green tea has long been linked with fat-burning and weight management. Green tea contains caffeine (in lower doses than your standard cup of coffee), which, as we mentioned above, is perhaps the most important ingredient when it comes to managing weight (Gunnars, K. 2023).
 

Green tea is also loaded with strong antioxidants known as catechins, with the most important catechin, EGCG, helping to accelerate metabolism. Green tea can improve the effect of certain fat-burning hormones and is particularly effective at supporting fat-burning when taken before exercise. This makes it a vital inclusion in thermogenic fat burner supplements (Gunnars, K. 2023).


 

Capsaicin


Capsaicin, a compound found abundantly in fruits and plants of the Capsicum family, such as bell peppers, jalapeno peppers, and chilli peppers, is a key ingredient in thermogenics. This versatile compound aids weight management by supporting metabolism, aiding appetite reduction, and reducing inflammation. This compound can also help with increasing oxygen consumption and body temperature, and as a result, facilitates the necessary calorie burning to support your body goals. Capsaicin's wide-ranging benefits make it a common and effective addition to various thermogenic pre-workout supplements (Preiato, D. 2020).


 

Carnitine


L-carnitine is an amino acid that is commonly found in thermogenic pre-workout supplements. This compound is said to support your body goals by helping you transport fatty acids into the cell’s mitochondria, where they are oxidised into usable energy. While there are several different types of carnitine, L-carnitine is the most common form included in thermogenic supplements. Carnitine may also play a role in reducing body weight, body mass index, and fat mass and can play a role in exercise performance (Mawer, R et al. 2023).


 

B Vitamins


B vitamins often go unnoticed as a crucial ingredient in thermogenics but don't underestimate their value when it comes to supporting your body goals. These vitamins play a vital role in energy production, particularly vitamin B3 (niacin), which helps convert carbohydrates into usable energy. Furthermore, vitamin B12 can play a role in weight management, with adequate levels of vitamin B12 supporting a lower risk of obesity. With its impact on fat metabolism and overall body composition, B vitamins are a common and beneficial ingredient in thermogenics (Sun, Y et al. 2019).
