Fat burner

A fat burner is a food supplement designed to support a fat-loss effort, alongside a suitable diet and regular physical activity. Let's be clear from the start: a fat burner does not melt fat on its own, and it does not replace your effort. It is a helping hand, not a miracle fix.

Behind the word "burner" sits several families of products that do not all work the same way:

• thermogenics (caffeine, green tea, guarana), which aim to support metabolism and energy expenditure;
• lipotropics such as L-Carnitine and CLA, associated with fat metabolism;
• appetite suppressants and satiety products, to help you manage hunger;
• drainers, which target the comfort linked to water retention.

At QNT, you will find all of these approaches in a single collection. The point of this page is to help you understand the differences so you can choose the burner that genuinely fits your goal, rather than buying at random.

Two main mechanisms come up whenever people talk about an effective fat burner.

Thermogenics rely on active ingredients like caffeine, green tea and guarana. The principle of thermogenesis: gently stimulate metabolism and the body's heat production, and with it your daily energy expenditure. That is the approach behind Riptek V2 Thermogenic, the range's thermogenic burner, and behind Fat Burner.

Lipotropics follow a different logic, tied to fat metabolism. L-Carnitine is traditionally associated with fat metabolism, and CLA (conjugated linoleic acid) is popular during cutting phases to support the maintenance of lean mass.

One honest and important point: studies show that a burner on its own has a limited effect. The number-one driver of fat loss remains the calorie deficit, meaning you burn slightly more than you eat. The burner adds to that foundation, it never replaces it. Used well, within a consistent routine, it can help you stay on the right track.

For many people the real obstacle is not the training: it is the cravings and the urge for sugar. This is where products focused on appetite and satiety come in.

Sugar Stop is designed to support control over sugar cravings, a key point when you are trying to cut your intake without constant frustration. On the satiety side, some burner formulas include fibres such as glucomannan (from konjac), known to swell in the stomach and encourage a feeling of fullness before a meal.

A few simple habits that make the difference:

• do not skip meals, or you will give in harder later;
• lean on protein and fibre, the most filling foods;
• drink enough water throughout the day.

An appetite suppressant is only useful as part of this overall routine. The goal is not to switch off your appetite entirely, but to help you hold a comfortable eating framework over time, without the repeated slip-ups that sabotage your effort.

Not everyone has the same rhythm, and not every hour of the day is equal. That is why QNT offers a day / night approach with two complementary products, the Day Burner and the Night Burner, both vegan.

The Day Burner is formulated for the daytime and for activity. It draws on energising active ingredients to support your metabolism when you are on the move, ideal before a session or at the start of the day.

The Night Burner, on the other hand, is designed without stimulants, so it fits into your evening without disrupting your sleep. One essential point: quality sleep is a full part of successful fat loss, because poor sleep throws off appetite and recovery.

The benefit of this day/night logic: you match the product to the time of day rather than relying on a single dose. It is also a practical answer for people who are sensitive to caffeine, who can keep the energising ingredients for the morning and avoid stimulants late in the day.

The question comes up very often: is there such a thing as a fat burner for women? The needs are not radically different, but some expectations are (body shape, comfort, water retention, managing cravings).

In the collection, Lipitek Women Fat Burner is positioned specifically for this use. Skinny Protein rounds out a routine nicely: it is high in protein and low in sugar, perfect as a filling snack or at breakfast.

A word on stimulant sensitivity: if you react strongly to caffeine (palpitations, jitters, disrupted sleep), turn to stimulant-free options like the Night Burner or to L-Carnitine approaches, and avoid taking them late in the day.

On the protein side, it is one of the most effective levers for losing fat while preserving muscle. It is also the most filling macronutrient, and the one that costs the body the most energy to digest. The most common question: how much protein per day to lose weight? A common benchmark during a fat-loss phase sits around 1.6 to 2 g of protein per kilo of body weight per day, spread across your meals, with the exact need varying by your weight, your activity and your goal. A 65 kg woman therefore often aims for an indicative intake in the region of 105 to 130 g per day. That is exactly what many diets are missing. For the detailed calculation based on your profile, our protein-for-weight-loss guides walk you through it step by step.

Beyond thermogenics, several targeted allies round out a fat-loss routine.

L-Carnitine is one of the most requested ingredients. It is traditionally associated with fat metabolism and remains a popular choice before cardio. The collection offers a wide range of formats: L-Carnitine 500 mg capsules, Maxi L-Carnitine 1000 mg tablets, and ready-to-drink liquid versions (L-Carnitine 2000 mg, L-Carnitine 3000 mg, L-Carnitine Liquid 6000, L-Carnitine Water). It is the ideal option if you want a single ingredient, with no stimulant.

CLA is readily used during cutting, to support the maintenance of lean mass.

Finally, the comfort linked to water retention is a real topic, especially at the end of a diet: Waterless is formulated to help you feel lighter and less bloated. Note that this is not fat loss, but water comfort.

Good to know: you can combine a thermogenic and L-Carnitine, as long as you respect the doses indicated on each product.

A burner only gives its best when it is used well. A few practical pointers:

• Thermogenics (Day Burner, Fat Burner, Riptek V2): rather in the morning and/or before training, never late at night because of the caffeine.
• Night Burner: in the evening, since it is stimulant-free.
• L-Carnitine: often before a cardio or sports session.
• Appetite suppressants / satiety: before the meals where you tend to give in, with a large glass of water.

Always follow the dosage shown on the label, never double the doses, and pair everything with good hydration. Many people run courses of a few weeks rather than taking it continuously all year.

The reminder that matters most: a burner fits into an overall approach (balanced diet + regular physical activity). That foundation is what makes the difference, the supplement is there to optimise it. To build a real slimming plan, especially after 40 or 50 when metabolism changes, explore our guides and our weight-loss collection.

Often skipped by sellers, but essential: side effects. Thermogenic burners contain stimulants like caffeine, which in sensitive people can cause jitters, palpitations, headaches or disrupted sleep, especially when taken late or in excessive doses.

A few simple precautions:

• start with a reduced dose to assess your tolerance;
• do not combine several sources of caffeine (coffee, pre-workout, burner) without accounting for it;
• avoid stimulants at the end of the day, and prefer the Night Burner or L-Carnitine instead;
• never exceed the recommended daily dose.

These products are for adults only. They are not recommended for pregnant or breastfeeding women, or for people sensitive to caffeine. If you have a health condition, are on medical treatment, or are in any doubt, seek advice from a healthcare professional before starting.

Used sensibly, with common sense and respect for the doses, QNT burners fit smoothly into a sports routine. Consistency and patience remain your best allies.
