A term commonly used with fat burning supplements is thermogenics. Thermogenic supplements help increase the body's temperature enabling the body to burn calories as heat; to be used as energy, thereby preventing them from being stored a fat. Effective thermogenic supplements are those that contain key ingredients that create a fat burning environment by working in synergy. The ingredients in Perfect Diet do that and also aid in reducing appetite and increasing short-term energy: Bitter Orange/Citrus Aurantium Bitter Orange has thermogenic properties, and helps to suppress the appetite. It also provides synephrine (6%) for increased energy. Bitter Orange contains a rare composition of five amines that are essential for switching one's metabolism into fat burning mode.

It also contains synephrine alkaloids that help the body to conserve energy when there is no food intake. As a result, Bitter Orange aids in the breakdown of fat, increases energy levels and increases the metabolic rate to burn calories. Guarana Extract Guarana is a high-energy source that increases mental alertness, fights fatigue, decreases the appetite, and is an excellent mood elevator. When combined with other ingredients it helps to boost their effect. Guarana contains natural caffeine and other phenolic-containing antioxidant compounds. They spur the body's ability to burn calories and unwanted fat cells through the thermogenic process. Guarana also contains the alkaloid compounds theobromine and theophylline, which helps curb appetite from sugar cravings and carbohydrate cravings, and increases weight loss. Green Tea Extract Green tea contains numerous compounds, including the flavonoid, catechin.

The antioxidant health benefits of green tea are well known. Green tea may help people to boost metabolism, reduce appetite and lose weight. When combined with the other ingredients it helps to boost their effectiveness to burn fat. It also helps to reduce fatigue and increase energy. White Willow Bark The bark of the white willow tree is a source of salicin and other salicylates – compounds. When combined with the other ingredients it helps to boost their effect to burn fat in elevating energy expenditure and promoting fat metabolism. Cayenne A thermogenic, natural ingredient, Cayenne has been shown to increase body temperature, thereby causing an increase in energy expenditure for thermoregulation. The active ingredient in cayenne is the alkaloid capsaicin. This compound helps raise the body's metabolic rate and enables the body to burn increased amounts of fat. Yerba Mate It is used as a natural stimulant for weight loss and as an appetite suppressant. It is also known for increasing energy and improving digestive systems. Yerba Maté contains mateine, a close relative of caffeine. Mateine acts like caffeine, but it does not have the side effects of caffeine. It will stimulate the mind as well as the body. Yerba Mate possesses great thermogenic and lypolitic properties, which helps to increase energy expenditure and fat oxidation.

It also contains saponins, which provides weight loss properties similar to the saponins in green tea leaves. Anderson T, Fogh J.
