As anyone who has been on that journey knows, fat loss is an exercise in dogged determination and painstaking persistence. Yet, such sacrifice is often not enough. At some point, fat in certain parts of the body may appear almost impervious to further diet and exercise. Progress is frustratingly slow. A failure to see results as soon as you expect them does not augur well for your morale. Understandably, many people fall by the wayside.
Fortunately, fat burners can help speed up the process. Actually, fat burners have been a central component of weight loss and workout programs for years now. They are not a monolith though. There are not only different brands but fat burning supplements are also of different types. Fat burners that accelerate the body’s natural fat burning process are widely considered the most effective since they ride on natural physiological mechanisms. Known as thermogenic fat burners, they stimulate the body’s metabolic processes responsible for breaking down fat. They derive their name from thermogenesis, which is the scientific name for heat generation. They differ from other types of fat burners that may rely on artificial chemical reactions to speed up fat loss.
Some of the best known naturally-occurring thermogenic fat burners include caffeine, capsaicin, garcinia cambogia, bitter orange and green tea. While some thermogenic supplements contain a single ingredient, most are formulated from multiple natural compounds. We looked at the thermogenic fat burner landscape and evaluated the different brands along several key factors. The result is the following list of the best five thermogenic supplements in the market.
BEST THERMOGENIC FAT BURNERS
A product of Wolfson Brands, PhenQ is a thermogenic fat burner that combines multiple ingredients with the aim of addressing different elements of weight loss.

Manufactured by Roar Ambition, Instant Knockout (also referred to as Instant Knockout Cut) is a thermogenic fat burner originally blended for professional athletes.

Few supplements come close to Burn XT in terms of the sheer number of customers and customer reviews. As one would expect with a product with such a large market share, there will be both positive and negative reviews. The overwhelming majority of past customers have largely good things to say about the Burn XT. They report rapid weight loss, falling appetite, shrinking waist size, increased energy and improved focus.
On the other hand, customers who have been dissatisfied with the product mention experiencing nausea, discomfort, dizziness, anxiety, lightheadedness, excessive sweating, chills, stomach pain, chest pain, dry eyes, reduced concentration, increased dependency (i.e. headaches if they miss a dose) and no weight loss at all.
Fat loss is a long and difficult journey. It becomes harder with age as the body’s metabolism embarks on a natural decline. This is perhaps one of the reasons a beer belly is a key feature of the dad bod. Excessive body fat is neither inevitable nor permanent though. Thermogenic fat burners are one of the more effective ways to burn through body fat. They accelerate metabolism, suppress appetite and raise energy levels.
But while they can speed up how fast you get to your desired weight, they are not a magic pill. All manufacturers advise that fat burning supplements must be paired with a proper exercise and diet program.
Speak to your doctor to ensure you are in the right state of health to use thermogenic fat burners. Ascertain that you do not have a history of being allergic or intolerant to any ingredient. Always check the ingredients of the supplement before you buy and use it. All credible supplement makers have this information readily available on their official website. Caffeine for example is a popular ingredient in fat burners but could affect sleep, digestion and mood.
Every thermogenic fat burner comes with a manufacturer-recommended dosage in addition to directions on when and how to take the pills. You can only be certain that it works if you stick to the right dosage.
Beware of fakes. As incomes rise across the globe and with the proliferation of unhealthy fast food, fat loss is quickly becoming a vital goal for an ever expanding segment of the world’s population. That has naturally given rise to a robust market for counterfeit fat burners.
Since they are simply a means of illegally making a quick buck, counterfeit fat burners do not adhere to the same standards and ingredients as the original. They could therefore be ineffective at best and life-threatening at worst. Always get your fat burner supply from the official website.

Frequently Asked Questions (FAQs)
Authentic thermogenic fat burners such as the five we’ve reviewed here do work. That being said, they are not magic pills. First, how effective a fat burner is will depend on the kind of exercise and diet regimen it is paired with. Second, do not expect dramatic results. More often than not, you should give thermogenic fat burners at least a month before you see visible outcomes.
Most thermogenic fat burners are made from natural ingredients only. This, at least in theory, makes them safe for nearly anyone looking to lose fat faster. It’s why you don’t need a doctor’s prescription to buy the pills. Nevertheless, talk to your doctor before you get onto any thermogenic fat burner. Find out if there are risks in the context of your current state of health. This is especially important if you are pregnant, breastfeeding, have a long term illness or are taking any long term medication.
How quickly you see results will depend on multiple factors including your body’s unique internal composition, the nature of the diet and exercise program you combine the fat burner with, the ingredients in the fat burner and how consistent you are with taking it. Certain benefits such as energy boosts and better moods will occur within hours and days of taking the first pill. The impact on weight loss however takes longer. Noticeable changes require anywhere from a few weeks to a few months.
Most people will not experience any side effects when they take thermogenic fat burners. Majority of fat loss supplements are made from natural ingredients. Nevertheless, there may be unpleasant side effects with some of the more common complaints including constipation, abdominal pain, nausea, headache and a slight rise in blood pressure.
Thermogenic fat burners that contain significant quantities of stimulants such as caffeine may trigger insomnia, heart palpitations, restlessness, anxiety, dizziness and headaches. So always check the ingredients before determining if a particular thermogenic fat loss supplement is the right one for you.
