Study Finds 6 Natural & Safe Fat Burners, Plus Risks of Weight Loss Supplements

What Are Fat Burners?

What qualifies a product as a “fat burner”? Fat burners are also called thermogenics. Thermogenic supplements seem to help you burn stored body fat by using the body’s fat reserves as a source of energy.

According to the School of Sport and Exercise Sciences at University of Birmingham, “The term ‘fat burner’ is used to describe nutrition supplements that are claimed to acutely increase fat metabolism or energy expenditure, impair fat absorption, increase weight loss, increase fat oxidation during exercise, or somehow cause long-term adaptations that promote fat metabolism.” (3)

Although their efficacy and safety are constantly scrutinized by the FDA and other organizations, manufacturers of thermogenic “diet pills” often claim that taking these supplements can help improve weight loss almost effortlessly by boosting your metabolism (the rate at which you burn calories). Some may also be at least somewhat helpful for decreasing your appetite, curbing cravings for junk foods and giving you more energy, which can be used for physical activity.

Are the weight loss claims about these ingredients necessarily true? It seems to depend on the type of thermogenic fat burners in question, the active ingredients that are used in the products, dosages taken and an individual person’s response. Active ingredients that are commonly used in thermogenic supplements vary by brand but usually contain a mix of stimulants, herbs and acids. Testimonials, along with findings from certain studies, suggest that thermogenics do seem to work for some — however in some cases their ingredients can also be dangerous or totally ineffective.

University of Birmingham researchers stated, “Based on the available literature, caffeine and green tea have data to back up its fat metabolism-enhancing properties. For many other supplements, although some show some promise, evidence is lacking.”
