Fat burners are supplements that work by increasing the resting metabolic rate and helping to eliminate body fat. The main ingredient in most fat burners is caffeine, which helps to lose weight by increasing metabolism and helping the body use fat for fuel. It also helps provide energy for exercise and other calorie-burning activities. Caffeine increases the breakdown of fatty acids that reside in adipose tissue, also known as abdominal fat.
Once these fatty acids are broken down, they enter the bloodstream and our bodies can burn them for energy. Appetite suppressant supplements claim that they decrease our appetite and, therefore, decrease the urge to eat. They work in different ways, including blocking the absorption of calorie-containing macronutrients and making our stomachs feel full, as in the case of fiber. Fat burners work by raising blood pressure and increasing total energy expenditure, which can eventually lead to weight loss over time.
When used correctly, fat burners will allow you to get the most out of every workout you do, allowing you to get in shape at a faster rate than you would without the use of fat burners. Soluble fiber supplements can help you burn fat by reducing your appetite and possibly reducing the amount of calories you absorb from food. A study published in the American Journal of Clinical Nutrition found that men who ingested the active ingredient in green tea (catechins) significantly reduced total fat area, waist circumference, thickness of skin folds and subcutaneous fat area. In addition to this, for a given amount of calories used during exercise, more calories will be obtained from body fat if caffeine is consumed before exercise.
Among these, caffeine, green tea extract and protein supplements are likely to be the most effective in helping to burn fat. CLA supplementation may also help to reduce cholesterol and triglycerides, decrease insulin resistance, improve the immune system and promote more efficient metabolic function. It is important to note that caffeine-containing fat burners should be cycled - a popular cycle is 2 to 3 weeks on and 2 to 3 weeks off - and that reducing the quality of rest can lead to greater fat gain. Finally, it is important to remember that while fat burners can help you reach your goals faster, they should always be used in conjunction with a healthy diet and regular exercise.
