Safety Score
- Green Tea/Matcha : Rich in catechins and caffeine, it boosts metabolism and increases energy expenditure
- Cayenne Pepper Capsaicin boosts thermogenesis and helps burn fat more effectively
- Ginger : Boosts metabolism and influences the satiety hormone (leptin)
- Coffee Caffeine naturally boosts lipolysis and enhances energy levels
- Citrus (lemon/grapefruit) : High in naringin, which promotes fat breakdown.
- Apple : Natural appetite suppressant due to its high pectin content
- Cinnamon : Regulates blood sugar levels and boosts thermogenesis
- Spirulina/Chlorella : Protein-rich superfoods with appetite-suppressing effects
- Guarana : Contains guaranine (similar to caffeine) which boosts metabolism
- Fat Burner (Supplement) : Combines several natural ingredients such as our fat burner DIX
What are fat burners and how do they work?
Les fat burners, are dietary supplements designed to optimise fat loss by acting on the metabolism, because the higher your basal metabolic rate, the more calories you will lose. They generally come in capsule or powder form, and contain a mixture of active ingredients that promote the burning of fat stored in the body.Ingestion
The active ingredients (caffeine, green tea, L-carnitine...) are absorbed by the body
Activation
Your basal metabolism increases = more calories burned at rest
Thermogenesis
The body temperature rises slightly, promoting fat burning
Lipolysis
Stored fats are mobilised and used as an energy source
What are the fat burners that you should absolutely avoid?
Les injectable fat burners are strictly prohibited in many countries (for example, France, the United States, the United Kingdom, Australia and Canada) because of the serious health risks they present. In a world where we want results a little too quickly, unfortunately we still see too many people turning to these dangerous solutions, often out of ignorance of the risks involved, and the only thing you risk quickly is death.
Injectable products: a deadly practice
Hypo-osmolar injections
Burst fat cells uncontrollably, causing severe tissue damage
Massive cell destruction, severe inflammation
Carboxytherapy
CO₂ injection under the skin. A non-medical practice that may cause gas embolisms
Potentially fatal gas embolism
Mesotherapy cocktails
Unregulated blends with an exact composition that is often unknown, even to the seller.
Unknown composition, unpredictable reactions
2,4-Dinitrophenol (DNP)
Initially used as pesticide and explosive, DNP is sometimes marketed as the "ultimate fat burner". It causes an uncontrollable rise in body temperature. There is no antidote.
Deadly hyperthermia, rapid fatalities even at low doses. Several deaths occur each year in the fitness world.

Normal: 37°C
⚠️ Avoid black market substances
-
Ephedrine
Prohibited substance in France and the United States due to its serious cardiac effects (arrhythmias, heart attacks)
-
Methylhexanamine (DMAA)
Powerful stimulant that can cause strokes, heart attacks, and severe hypertension
-
Uncontrolled dosages
Illicitly imported products sometimes containing 10 times the recommended dose of active substances
Massive bruising
Emergency surgery required
Serious infections
Antibiotic-resistant
Tissue necrosis
Permanent scars
Heart failure
Potentially lethal
We can only advise you to opt for legal fat burners and to understand how they work to avoid any unpleasant side effects
What are the side effects of legal fat burners?
Even the legal fat burners can cause side effects when used incorrectly or overdosed. Mind you, we're light years away from the horrific effects of the burners described in the previous paragraph. Nevertheless, our daily experience with sportsmen and women shows us that the majority of problems arise from poor management of the dose ingested during the day.Overdosing on fat burners
Again, it's a case of trying to outrun nature, so we'd advise against it:- The intake of several fat burners at the same time (thinking of speeding up results)
- The combination with some pre-workouts highly caffeinated
- Ignoring your daily coffee/tea consumption
Caffeine: watch out for excess!
☕ Calculate your daily caffeine intake

🚫 Who should avoid fat burners?
For safety reasons, and even though well-dosed fat burners are generally safe supplements, some individuals should refrain from using them for precautionary measures. You'll quickly see from the list that this is simply common sense:
Pregnant or breastfeeding women
Heart issues
Anxiety disorders
Kidney/Liver Issues
Caffeine sensitivity
