Whether you’ve got a lot of experience with fat burners or are new to the concept, one of the most popular formulas seen rising to the top in recent years is a ‘thermogenic’ fat burner.
Fat burners are usually plant-based supplements that tackle many aspects of weight loss – from suppressing your appetite, to enhancing your body’s fat-burning potential so you lose more weight quicker.
Thermogenic fat burners aim to take your body’s fat burning to the max through the process of thermogenesis. Before we go into what this process is and how it works in more depth, here’s an overview of what benefits you could experience from a thermogenic fat burner:
- Increased metabolism – even at rest
- More natural energy
- A better breakdown of fat stores
- Reduced hunger
- Improved focus, mood and motivation – especially during workouts
It’s important to say that thermogenic fat burners – although they are generally packed with scientifically-backed thermogenic ingredients – they are not miracle pills which will magically melt all your excess fat on their own. Generally, to see the best results, you need to accompany your supplement with a healthy diet and some form of exercise plan too.
But as the market is saturated with fat burners which all claim to enhance thermogenesis to the utmost degree, how can you cut through the noise to find the one for you?
That’s where we come in! We’ve trawled through the thousands of supplements on the market today and chosen the top 5 best thermogenic fat burners based on their clinically-backed ingredients, price, benefits and dose size to make it easier for you to decide.

What is a thermogenic fat burner?
Before you see the best, it’s probably important for you to understand what a thermogenic fat burner actually is. Usually, these supplements are made up using plant-based ingredients which collaborate together to increase your body’s fat burning potential.
Thermogenesis as a process literally means the heating of your body to stimulate your metabolism, encourage lipolysis – the breakdown of fat stores – and transform fat into usable fuel you can burn off [Source 1]. As your temperature rises, your body works to return it to normal which is why thermogenic fat burners tend to keep your metabolic rate raised for longer, encouraging more calorie burn [Source 2]. This process utilizes more calories than your metabolism would normally need which is how you can see increased fat loss [Source 3].
Why take a Thermogenic Fat Burner
Thermogenic fat burners offer a number of benefits – specially to weight loss. Everybody is built slightly differently and react in different ways to weight loss. Some people have slower metabolisms which makes it difficult to lose weight naturally. Other people find high intensity workouts a challenge.
Whatever the reason, thermogenic fat burners could offer that extra boost to your weight loss potential. If you’ve reached a plateau with your fat loss and feel like progress is slowing, thermogenic fat burners can rejuvenate your body’s natural processes into shedding those stubborn pounds.
Obviously, you’ll need to keep up your workouts and stick to a healthier diet but thermogenic fat burners could offer a chance to take your results to the next level and reach your body goals easier.
Best thermogenic fat burner ingredients
On the market today, there are many ingredients that companies use to inject that thermogenic aspect into their fat burner. However, it’s worth noting, not all inclusions used are side effect free – which is why we’ve listed the safest ones below to look out for below.
As a well-known stimulant, you’ve more than likely heard of caffeine. But what might surprise you is its huge amounts of benefits – especially to weight loss. Not only does it have thermogenic qualities which boosts your metabolism for increased fat burning, it can also reduce your appetite [Source 4] too. Caffeine also triggers hormones like adrenaline which can activate muscles [Source 5] and enhance endurance during workouts [Source 6], as well as stimulate fatty acids to be released from storage so they can be used for energy. By doing this, you’ll be able to burn off stored fat quicker. Other benefits include improved energy, focus [Source 7] and mood [Source 8] which could all contribute towards a better attitude to your weight loss journey.
A popular herbal tea, green tea has a whole host of benefits to help aid weight loss. It contains two compounds which have thermogenic effects – caffeine [Source 9] and epigallocatechin gallate (EGCG) [Source 10]. These two combined could help boost your metabolism significantly, with a 16% increase in fat burning for 24 hours after ingestion [Source 11]. Whilst caffeine helps the release of adrenaline, EGCG complements it by slowing down the breakdown of the hormone so that thermogenesis is prolonged for maximum effects [Source 12].
This fiery component is often found in chili peppers like cayenne and is the element which gives them the spice – and makes it a powerful thermogenic. Capsaicin, like caffeine, increases adrenaline in your body, which kickstarts your metabolism so you can burn more calories [Source 13]. There are many studies which link capsaicin to enhanced satiety, which is essentially the feeling of fullness. Through this delaying of hunger, it is known to reduce calorie intake [Source 14] alongside oxidizing the fat already stored in your body to increase fat reduction overall.

Advantages to Using a Thermogenic Fat Burner
A thermogenic fat burner is essentially targeted towards speeding up your weight loss by helping to convert stored fat into usable energy to burn off. Benefits of taking thermogenic fat burners could include:
- Quicker fat loss – Through the stimulation of your metabolism for longer each day, your fat stores will be harnessed and transformed into fatty acids which you can burn off. This will help you shed those stubborn pounds easier.
- Reduced appetite and cravings – Many thermogenic ingredients have been linked to quelling hunger and keeping you feeling fuller for longer. By reducing your appetite you can, in turn, reduce the calories you consume per day which will help speed up the fat loss process.
- More energy – People with slower metabolisms can often find themselves feeling sluggish and fatigued. Thermogenic ingredients activate your metabolism and encourage it to work faster for longer, which will keep energy levels up throughout the day.
- Improved athletic performance – Many of the thermogenic ingredients used in thermogenic fat burners can boost focus and attention-span, whilst activating muscles which will enhance your endurance for altogether better workouts.
