Using too many natural “fat burners”, especially supplements, can lead to acute liver failure. Globally, people are fighting obesity and seeking more effective and unconventional methods of reducing weight, such as natural and herbal dietary supplements. Fat burners are believed to increase metabolism, burn more calories and accelerate fat loss. Despite patients' perception that herbal remedies have no adverse effects, some supplements are associated with severe hepatotoxicity.
This report describes a young, healthy woman with sudden liver failure who required an emergency liver transplant caused by a dietary supplement and a fat burner containing usnic acid, green tea and guggul tree extracts. A thorough investigation, including histopathological examination, revealed no other cause of hepatotoxicity. This case adds to the growing number of reports of hepatotoxicity associated with dietary supplements containing usnic acid, and highlights that herbal extracts from green tea or the guggul tree may not be exempt from adverse effects. Until these products are more regulated and their advertising is better analyzed, doctors and patients should become more familiar with the herbal products that are commonly used as weight-loss supplements and recognize those that are potentially harmful.
Many naturally occurring ingredients can cause significant side effects and toxicity when taken in excessive doses or for long periods of time. Fat burners are nutritional supplements that help burn fat. They improve energy expenditure and fat metabolism and lead to weight loss. They can also reduce fatigue and improve endurance.
However, you should also be aware of the side effects of fat burners. Excessive intake of fat burners can cause liver damage, fluctuations in blood pressure, anxiety, headaches, heart attack, insomnia and nausea. If you experience any adverse effects, discontinue use. In addition, consult your doctor regarding the dosage of these supplements.
The ingredients in fat burners improve endurance, alertness, memory, a sense of stamina and reduce fatigue. We describe the case of a 21-year-old male who presented painless jaundice and a weight loss of 25% of body weight after 8 weeks of administration of thermogenic supplements with fat burners. Let's take a closer look at how fat burners work, what are the risks of side effects and the long-term dangers. If a fat burner contains unusual ingredients that are not normally found in the diet, your liver may need to process them before you can use them.
Thermogenic fat burning treatments are used to increase an individual's basal metabolic rate, thus mimicking exercise and inducing weight loss. Many fat burners contain substances such as bitter orange, which can raise blood pressure and heart rate to levels that aren't safe. Usnic acid is still available and is advertised on the Internet as an ingredient in several other dietary supplements and fat burners. The best fat burners combine several ingredients to promote fat loss and body recomposition in several ways at once, while lower quality weight loss pills will focus on one or two pathways.
These supplements contain several ingredients, each with its own specific mechanism of action, and when combined, it is suggested that they cause a cumulative effect on overall fat and weight loss. Capsimax Cayenne Pepper Extract provides stimulant-like fat loss benefits with no negative side effects. But if you look at the ingredients in most fat burners, you'll often find a long list, natural or not, that claim to speed up metabolism, burn calories, melt fat and encourage better performance. The best stimulus-free fat burners usually contain appetite suppressants, which work by increasing the feeling of satiety.
Many of the ingredients found in fat burning pills or powders are legally prohibited in some countries as they can cause high blood pressure and fluctuations in blood pressure.
