Fat burners comprise a class of supplements that are catered for those who wish to shed a few pounds naturally without the use of prescription drugs, tedious dieting or workout techniques. Fat burners are not intended to substitute a proper diet and exercise routine but to facilitate fat disposal for those who want to set off on the right foot in their journey to attain their ideal weight. There are various classes of fat burners that have differing mechanisms of action. These may act to enhance energy levels, suppress the absorption of fat molecules into body tissue, induce the process of thermogenesis or lipotrophism and suppress the appetite. Fat burners may fall into one or more of these categories.

Enhancement Of Energy Levels

Most fat burners will optimise energy levels by correcting the utilisation of fatty acids and other macronutrients. Carnitine is a popular energy enhancing agent in fat burners that has been scientifically proven to augment ATP reserves in muscle tissue. More specifically, carnitine has been dubbed as the “fat transporter” that facilitates the transport of fatty acids into the mitochondria which uses this as a source to produce high levels of ATP. This can subsequently promote an increase in the duration and intensity of exercise as the individual carries additional energy supplies. Caffeine and Guarana are commonly incorporated into fat burners for an immediate and short-term energy boost.

Fat Absorption Inhibition

Some positively charged substances such as chitosan have the ability to bind to the negatively charged fat and lipid molecules within the digestive system and prevent its absorption into fat tissue. However, it should also be mentioned that chitosan may also reduce the solubility of water soluble vitamins.

Thermogenesis

Many fat burners act to increase basal metabolic rate and release heat as a by-product to drive the process of burning fat and excess calories to create a calorie deficit. Caffeine, green tea and salicin are common thermogenic compounds found in fat burners. Ephedra was once considered to be effective although has recently been implicated in fatal side-effects and death cases have also been documented from the use of this herb.

Lipotropic Process

Lipotrophic compounds such as carnitine, inositol, choline, chromium and hydroxycitric acid in fat burners assists in the catalysis of fat molecules into free fatty acids. These are then transported from the liver and gall bladder into the bloodstream.

Supression Of Appetite

Many fat burners are carefully designed to reduce sugar cravings and maintain blood glucose levels. The components that permit this contain a bulky structure that directly suppresses the hunger response center in the brain. Hoodia gornii, garcinia cambogia, glucomannon and green tea acts as appetite suppressants in fat burner formulations.

In conclusion, the purpose of fat burners is to accelerate fat loss for those who are classified as obese or others who desire to shed a few kilos to maintain their jean size. Always remember to check the reputability of the brand before purchasing rather than wasting money through a tedious process of trial and error.
