Fat burners are food supplements marketed to support weight loss by raising metabolism, reducing appetite and lifting energy levels. MyProtein, a well known name in sports nutrition, sells a range of products in this category. This guide reviews those products, the ingredients they are built on and the directions for use given by the manufacturer.
It is also written with facility operators in mind. Clubs, boutique studios, hotel wellness areas and corporate gyms are regularly asked about supplements, and some sell them at reception. Two things follow: what your staff may say about a supplement is regulated, and what actually changes body composition in your members is the training they do on your floor. Both points are covered below.
Why people use a fat burner
The claims made for the category, as presented by manufacturers, are the following.
- Increased metabolism. Fat burners contain ingredients presented as stimulating metabolism and therefore helping to burn more calories.
- Reduced appetite. They are marketed as helping to control cravings and to reduce overall calorie intake.
- Increased energy. They are presented as providing an energy boost, which can support physical performance and endurance.
- Improved muscle definition. By supporting a reduction in body fat, they are said to allow better muscle definition.
These are marketing positions rather than established outcomes. In the European Union, only health claims authorised under Regulation (EC) No 1924/2006 may be used commercially, and the great majority of slimming and fat burning claims are not on that list. If you resell supplements in your facility, the wording on your shelf and on your website falls under the same rules as the manufacturer, so check what you are allowed to state before you print it. National rules apply on top of that, so verify the position in the country where you operate.
The MyProtein fat burner range
Thermopure
Thermopure is one of the best known products in the MyProtein range. It combines several ingredients intended to support fat loss and physical performance.
Main ingredients: green tea, known for its antioxidant properties and presented as raising metabolism; L-tyrosine, an amino acid; caffeine, a stimulant presented as raising metabolism and energy; black pepper extract, included to support the absorption of the other ingredients.
Directions: three capsules taken thirty minutes before exercise.
CLA
CLA, conjugated linoleic acid, is a naturally occurring fatty acid presented as supporting a reduction in body fat while helping to maintain lean muscle mass.
Main ingredient: CLA, presented as helping to mobilise stored fat so that it is used as an energy source.
Directions: two capsules with each main meal, preferably three times a day.
Impact EAA
Impact EAA is an essential amino acid formula aimed at supporting muscle recovery. It sits in this guide because it is often bought alongside a fat burner during a cutting phase, not because it is one.
Main ingredients: essential amino acids, which support muscle protein synthesis and recovery.
Directions: follow the dosage printed on the pack, since the product is sold in more than one format. It is generally taken before or during training.
L-Carnitine
L-Carnitine plays a role in transporting fatty acids into the mitochondria, where they are used as energy.
Main ingredient: L-carnitine, presented as helping to mobilise stored fat so that it is burned as energy.
Directions: two capsules once or twice a day, preferably with meals.
THE Thermo-X
THE Thermo-X is a thermogenic supplement designed to support fat loss by raising body temperature and metabolism.
Main ingredients: green tea extract, presented as raising metabolism; caffeine, for an energy boost; L-tyrosine; capsicum, presented as increasing thermogenesis.
Directions: two capsules thirty minutes before exercise.
Availability differs from one national MyProtein store to another, so check the range and the formulation offered in your own market before recommending a specific product.
Getting the most out of a supplement protocol
Follow a balanced diet
Fat burners work best alongside a healthy, balanced diet. Plenty of vegetables, lean protein and whole grains, with processed and high sugar foods limited.
Train regularly
Exercise is what burns calories and changes body composition. Combining cardio work with strength training gives the best results, and no supplement substitutes for it.
Stay hydrated
Drinking enough water matters for metabolism and general health. Aim for at least two litres a day.
Sleep enough
Quality sleep is decisive for recovery and metabolism. Seven to nine hours a night is the target.
Follow the directions
Always respect the recommended dosage and never exceed the stated dose, to avoid side effects. Several products in this category contain caffeine, and stacking two of them multiplies the dose without the user noticing.
What this means for a facility
Three practical points if you sell or recommend supplements on site.
Your staff are not prescribers. Trainers can explain what a product contains and what the manufacturer states; they should not present a supplement as a treatment or promise a result. Members with a health condition, a pregnancy or a medication should be referred to a health professional. Anyone starting a new supplement should be advised to consult one first.
Competitive athletes need to check status. Members subject to anti-doping rules should verify each product against the applicable national and international lists before use.
Equipment does the work supplements are credited with. Body composition changes come from a calorie deficit and consistent training. A floor that delivers that needs cardio capacity at peak times and enough strength stations to keep sessions moving: our professional cardio equipment and strength training machines are built for continuous commercial duty, which is the difference between a programme members can follow and one they abandon. If weight loss is the core promise of your offer, our guide to equipment for weight loss programmes sets out how to build the floor around it.
Frequently asked questions
Do fat burners work without training?
No supplement replaces a calorie deficit and regular exercise. Manufacturers position these products as an addition to a weight loss routine, not as a substitute for one.
Can a gym sell supplements at reception?
In most European markets yes, subject to food supplement labelling and notification requirements and to the rules on health claims. Verify the requirements applicable in your country before stocking anything.
Which product suits which goal?
Thermopure and THE Thermo-X are the thermogenic products in the range, taken before exercise. CLA and L-Carnitine are taken with meals or across the day. Impact EAA is a recovery product rather than a fat burner.
What should staff say when asked for a recommendation?
What the product contains, what the manufacturer directions are, and a recommendation to consult a health professional before starting. Nothing about expected results.
Conclusion
MyProtein fat burners can be a useful addition to a weight loss routine when they are used correctly and combined with a balanced diet and a regular exercise programme. Choose the product that matches your needs and goals, follow the guidance above, and consult a health professional before starting any new supplement.
