What are natural fat burners?
Natural fat burners are also known as regular fat burners. They are dietary supplements for weight loss that can be sold freely because they do not contain any problematic ingredients. Unlikeextreme fat burner, which often contain highly potent stimulants such as ephedrine, pseudoephedrine, or yohimbine, natural fat burners are composed of relatively mild, well-tolerated ingredients that do not affect hormone levels. (The only exception is fat burners containing 3,5-diiodo-L-thyronine, a derivative of the thyroid hormone T2, which we will discuss further below.)
Natural fat burners only stimulate fat burning; they have no significant psychological impact. In particular, they don't have a stimulating effect, so they don't impair sleep quality. For people who simply want to lose weight—and who don't want to do it in record time or strive for an ultra-toned look as a result—regular fat burners are by far the better choice than hardcore fat burners.
How do natural fat burners work?
Natural fat burners work through different mechanisms:
Mechanisms of action of “normal” (natural) fat burners
- Optimization of fat metabolism:Most natural fat burners ensure that fat metabolism (which is disrupted in many dieters) gets back on track. Ingredients such as choline and L-carnitine improve fat digestion and facilitate the transport of fatty acids in the bloodstream, making it easier to use body fat for energy production.
- Increase in thermogenesis:Some substances contained in natural fat burners increase heat production in the body. This increases calorie consumption – even at rest.
- Appetite control:Depending on their composition, natural fat burners also keep blood sugar levels stable so that cravings do not occur.
- Energy boost:Natural fat burners also have a stimulating effect – if they contain caffeine. Unlike the amphetamine-like substances found in extreme fat burners, however, caffeine is generally very well tolerated. Its effect on the central nervous system is also much weaker than, for example, that of DMAA (1,3-dimethylamylamine).
- Blocking fat storage:To prevent ingested dietary fat from ending up in the body's fat deposits so quickly, some natural fat burners contain substances that make it more difficult to store triglycerides.
It's important to note, however, that with natural fat burners, even more so than with extreme fat burners, a tailored diet and an active lifestyle are crucial to their effectiveness. These aren't diet supplements in the true sense of the word. If you don't simultaneously curb your eating and don't exercise at all, you won't achieve weight loss even with the best natural fat burner. These supplements can only have an effect if your body is already in "weight-loss mode." They can then accelerate weight loss.
What types of natural fat burners are there?
Natural fat burners are an incredibly broad field. It can be roughly divided into the following categories:
Single-substance fat burner
A large part of the range of natural fat burners consists of products that contain only a single substance – e.g. green tea extract (seeGreen Tea from Olimp), Acai berry extract (seeAçai from Haya Labs), raspberry ketones (seeRaspberry Ketones from Haya Labs) or chrome (seeChromium Picolinate from Haya LabsSuch "single-substance" fat burners are ideal for anyone who relies on the effects of a specific plant substance or mineral for weight loss and doesn't want to take any additional active ingredients (perhaps because they already take many supplements). The risk of intolerance is minimal.
Fat burner with caffeine
Another portion is accounted for by multi-ingredient preparations that contain, among other things, caffeine. These have a stimulating effect to some extent—but no more than a cup of coffee. Of course, the daily dose plays a role: The productThermo Speed Hardcore from OlimpFor example, has a total caffeine content of just over 90 mg per capsule. The manufacturer recommends 3 capsules per day, which would be equivalent to 3 cups of coffee. Therefore, you should always pay close attention to the caffeine content per serving when using caffeine-containing fat burners. Natural fat burners containing caffeine are generally a good thing because they not only increase fat burning but also provide energy. This makes it easier to maintain an active lifestyle while dieting. However, such fat burners are less suitable for people who are sensitive to caffeine.
Fat burner without caffeine
Then there are fat burners without caffeine, likeFAT-X from Biotech USAorLipo-Shift by NTEL NutraThese fat burners rely exclusively on mild substances such as Garcinia Cambogia fruit extract, L-carnitine, CLA, or raspberry ketones. The advantage: They can be taken at any time of day, even in the evening. (In fact, the product Lipo-Shift is specifically designed for evening consumption; it even contains the sleep hormone melatonin.) While fat burners without caffeine are not always fat burners without stimulants—some, likeAlpha Lean from Brawn Nutrition, namely they contain theobromine, which is found in cocoa beans – but in general it can be said that they do not have a stimulating effect.
Fat burner with thyroid hormone
And then there are fat burners that contain 3,5-diiodo-L-thyronine, such as the productBrawn Nutrition Thyro Lean V2L-thyronine is available without a prescription, but the drug is controversial. In animal experiments with mice, it did cause a significant reduction in body fat [1], and human studies also showed a significant positive effect on lipid metabolism. However, more recent studies also suggest a certain impairment of the hypothalamic-pituitary-thyroid axis [2]. In other words: L-thyronine can probably be used to burn fat quite effectively – but this can lead to a negative feedback effect on the endogenous production of thyroid hormone. Therefore, fat burners containing 3,5-diiodo-L-thyronine cannot be classified as fat burners without side effects.
Losing weight with fat burners: What can you expect?
In any case, it's no surprise. Regular fat burners or natural fat burners can increase the fat burning rate – but firstly, only if fat burning is actually taking place (i.e., when the body needs to mobilize fat reserves for energy), and secondly, even with fat burners, the fat burning rate doesn't increase dramatically. Belly fat or hip fat won't melt like butter in the sun.
To illustrate: With a normal weight-loss diet, where the calorie deficit is moderate (at around 500 kcal/day), you can lose about 1 pound of body fat per week over the long term. A little more at first, then a little less later. After 10 weeks, you would have lost 5 kg of body fat. If you use natural fat burners, the fat loss rate increases by perhaps 20 percent. This means that with fat burners, you can lose an additional kilo of fat within 10 weeks (a total of 6 kg instead of 5 kg). Doesn't sound like much more? Well, the difference is still four packets of butter. Anyone who has ever stacked four packets of butter on top of each other can roughly imagine the visual impact this has on their body.
Supplements for fat loss – which are the best fat burners?
So which fat burners are the best? Are extreme fat burners better than natural fat burners? They really should be better; after all, they contain more potent active ingredients, right? The answer isn't that simple, though. Yes, hardcore fat burners are more powerful than regular fat burners; but you can't take them long-term. They're so fraught with side effects that continuous use for months isn't advisable. Extreme fat burners are therefore of little help in a long-term diet. On the contrary: people who are severely overweight (and anyone planning a long-term diet is very likely severely overweight) generally don't have a healthy cardiovascular system. By consuming extreme fat burners, they risk health problems, including stroke. Extreme fat burners are therefore only suitable for people who want to reduce their already low body fat percentage to an even lower level. Natural fat burners, on the other hand, can be used safely by beginners, even for several weeks or months. It is possible that you will become accustomed to caffeine (with fat burners containing caffeine), but there is no reason to fear anything worse.
What side effects do natural fat burners have?
The spectrum of side effects of natural fat burners depends on their composition.
Natural fat burners without caffeine and without 3,5-diiodo-L-thyronine have virtually no side effects, except perhaps heartburn and mild nausea when taken on an empty stomach.
Fat burners containing caffeine can cause typical caffeine side effects, such as heart palpitations, mild dizziness, restlessness, finger tremors, and difficulty falling asleep. Caution is also advised with products that contain synephrine (a plant compound found in bitter orange and chemically related to ephedrine) in addition to caffeine: synephrine and caffeine both affect the cardiovascular system. Combined use can lead to a sharp increase in heart rate, resulting in tachycardia or cardiac arrest [3]. Products such asTherm Line Forte by Olimpare therefore not for people with a weak heart.
As mentioned above, it cannot be ruled out that fat burners containing the ingredient 3,5-diiodo-L-thyronine may negatively affect the body's own thyroid hormone production. However, the available research on this topic is still rather limited.
