In recent years, fat-burners have been rapidly growing in popularity. With greater numbers of people now choosing fat-burners as a method of achieving fast and easy weight loss, the slimming supplements are now stocked in nearly all supermarkets, pharmacies and health stores. The latest generations of fat-burners are even used by athletes across a range of different sports due to their ability to improve mental alertness, energy levels and endurance.  

Be Careful When Choosing Your Brand  

Of course, with all fat-burners there are good ones and bad ones. The bad ones are usually manufactured by companies looking to make a quick buck, using seductive advertising to take advantage of customers’ hopeful emotions. The large number of these useless products with their repeated false promises is the main reason why weight loss supplements generally receive a lot of bad press from nutrition and health experts. However, there are plenty of good fat-burners available on the market that can be used to enhance fat loss and achieve genuine visible results. Although many of these slimming products will have a particular scope of action, the most reliable ones tend to use a combination of different methods in order to help reduce your calorie intake and let you reach your weight loss targets.

The three main methods of effective fat-burners are:  

Increased thermogenesis: Thermogenesis refers to heat creation within the body, which allows for increased calorie burning and accelerated fat oxidation. Exercise alone can increase metabolism and stimulate thermogenesis but many modern fat-burners contain an array of natural ingredients that help to further promote this bodily process.

Stimulated energy levels: Taking part in exercise or sporting activities is the best way to expend calories and burn fat but a common feature of dieting is depleted energy levels and low stamina. Not only do increased energy levels allow for greater physical exertion, they also elevate mood and provide the motivation to remain focused on achieving your desired body weight.

Appetite suppression: Some fat-burners also aim to increase satiety by sending signals to the brain to tell it that you are full. By repressing hunger and leaving you feeling completely satisfied, they allow you to resist the temptation to over-indulge and greatly reduce your daily calorie intake.  

Understanding the Ingredients   The key to understanding fat-burners is learning about the ingredients and how they interact with each other. Most people want to purchase a product that delivers maximum results but it is also very important to select a product that comes with the least side effects. Ephedrine, derived from the Ephedra plant, used to be one of the most popular ingredients in thermogenic dietary supplements for its unrivalled power and effectiveness. However, the stimulant carried with it a number of potentially harmful side effects and was banned in the UK in 2007. Fortunately, there have been significant advancements in the food supplement industry and the majority of fat-burners are now made from natural herbal extracts, meaning that they are capable of promoting substantial weight loss without producing any dangerous side effects.

A good fat-burner will usually contain a combination of the following ingredients:  

Trimethylxanthine (Caffeine)

Trimethylxanthine is the medical term for pure caffeine and it is no coincidence that it is the most active ingredients in almost every single slimming supplement. As well as prolonging and heightening the effects of many other compounds by acting as a catalyst, it helps to fight the dreaded ‘dieting fatigue’ by stimulating the brain, rapidly increasing energy levels and preventing drowsiness. The effects of stimulants such as caffeine can be similar to experiencing a minor adrenaline rush; your heart begins to beat faster, your lungs open wider and your body temperature rises.  

Citrus Aurantium (Bitter Orange)

Citrus Aurantium, commonly referred to as Bitter Orange, has become the thermogenic, weight reduction replacement for Ephedrine. It provides similar properties to the outlawed substance without the negative side effects, making it a common feature in the ingredients list of any good fat-burner. The active ingredient in the Far Eastern fruit is the adrenergic amine Synephrine, which is commonly thought to reduce food cravings and stimulate energy while thermogenically melting fat reserves.   Green Tea Green Tea has become an increasingly popular addition to successful weight loss supplements. The popular Chinese herb has been used for centuries in a variety of cultures and the amazing benefits can be enjoyed by all age groups. The active constituents in Green Tea are a collection of health-promoting flavonoids known as Catechin polyphenols and are contained in the herb’s juices and enzymes. The most abundant of these powerful anti-oxidants is Epigallocatechin Gallate (EGCG) and it has an important role to play in the weight loss process. By inducing thermogenesis and boosting metabolic rate, it is able to intensifying fat oxidation without increasing heart rate, which may lead to fat loss, more specifically the loss of visceral fat (fat that accumulates inside the abdominal cavity and surrounds the internal organs).  


Nicotinamide is a form of Niacin (Vitamin B3) that is good for improving muscle tone and performance as well as removing fat from the blood. It also helps to regulate the metabolism and is essential for the normal function of the nervous system and gastrointestinal tract.   L-Tyrosine L-Tyrosine is a metabolism-boosting amino acid that has been shown to optimise the production of thyroid hormone levels. It is a precursor for the important neurotransmitters Dopamine, Epinephrine and Norepinephrine, all of which have been shown to control mood, improve cognition and successfully suppress appetite. L-Tyrosine also helps to prevent the energy crashes that are usually associated with caffeine-based fat loss supplements.  

Guarana Seed

Guarana Seed is an organic substance native to the Amazon basin and is another very popular ingredient in the best fat-burners. The highly-effective stimulant contains approximately 2 ½ times the concentration of caffeine found in coffee beans and has been hailed for its properties to act as a thermogenic stimulator. Guarana Seed can also be used as a mild diuretic to help reduce the effects of water retention.   Chromium Picolinate Chromium Picolinate is a natural compound that combines the chemical element Chromium with Picolinic Acid. It is thought to reduce insulin resistance, significantly improve glucose metabolism and assist in the breakdown of fat. However, one of the most attractive benefits of Chromium Picolinate is that it allows you to reduce body fat while retaining muscle.  

Recommended Products   Amazon offers a wide range of safe and effective fat-burners from established UK manufacturers such as FORZA, who launched the UK’s first legal fat-burner back in 2007. It is recommended that you always buy from companies with GMP facilities and who are ISO certified. Fat-burners contain a range of benefits for people who want to lose weight but it is still important to consider the pros and cons before incorporating a product into your diet.
