Before fat can be burned it must be broken down into small particles to free fatty acids and glycerol. This process is called Lipolysis . Hormones like cathecolamines and chemical compounds like xanthines found in the Yerba Slim formula have lipolytic activity. These ingredients aid in lipolysis allowing your body to breakdown fat and turn it into energy. Daniel Mowrey, Ph.D. states that Yerba Mate, a main ingredient in Yerba Slim , possesses the best combination of xanthine properties possible.

Clinical Studies:

The positive effects of the ingredients in the Yerba Slim formula have been clinically studied and proven to help with weightloss and appetite management. Below are a few of the clinical studies relating to the Yerba Slim ingredients.

Case 1: A study of thermogenic effects of commercially available plant preparations done at the Institute of Physiology at a Switzerland University showed an increase in energy wastage and increased lipolysis as a result of taking Yerba Mate. The study also showed that Yerba Mate resulted in "a significant decrease in RQ indicating an enhancement in the proportion of fat oxidized, a favorable effect for decreasing body fat."

Case 2: Green tea, by containing high quantities of pharmacologically active compounds can exert a thermogenic and therefore an anti-obesity action. Green Tea showed a reduced gastric and intestinal fat digestion as well as a reduction of lipid emulsification process. Green Tea was shown to be an effective stimulant for tissue thermogenesis. In a study of 10 healthy men, treatment with the green tea extract resulted in a significant increase in 24h energy expenditure and a significant decrease in 24h respiratory quotient. Administration of green tea extract stimulated thermogenesis and fat oxidation and this extract has the potential to influence body weight and body composition via changes in both energy expenditure and substrate utilization.

Case 3: A similar study of 70 patients 20 to 69 years of age, showed a continuing decrease of body weight as well as waist circumference. At the end of the study, mean body weight was decreased by 4.6% and waist circumference by 4.48%. The study concluded that Green Tea significantly increased energy expenditure and lowered body weight.

Ingredients:

Yerba Mate: is an evergreen tree growing wild in South America. It is used as a stimulant for weight loss and as an appetite suppressant. It is also known for increasing energy and improving digestive systems. It has been used by Native Americans since ancient times in a tea form as a daily stimulant. Its traditional uses were to aid against fatigue, nervous depression and pain. The herb is currently being used in the United States as stimulant for the central nervous sytem and as a dietary supplement.

Daniel Mowrey, Ph.D. calls Mate "An invigorator of the mind and body, a natural source of nutrition, and a health promoter." He also states that Mate is used to "boost immunity, retard aging, combat fatigue and control the appetite." Yerba Mate has the ability to increase mental alertness and acuity and to do it without any side effects resulting in more energy and vitality. Yerba Mate has become a favorite of body builders and anyone interested in the health benefits of exercise.

The metabolic effects of Mate include the ability to maintain aerobic glycolysis (breakdown of carbohydrates) during exercise . This results in burning more calories and loosing weight. It also eliminates the sensation of hunger meaning you eat less and lose more weight.

Guarana: is an evergreen vind indigenous to the Amazon basin. Guarana has been used in connection with athletic performance, fatigue, weight loss and obesity. The indigenous people of the Amazon used Guarana to decrease fatigue as well as to reduce hunger. It is also know to stimulate the central nervous system and increase metabolic rate.

Cayenne: has traditionally been used as medicine for centuries. It has shown reductions in appetite in a double-blind trial, studying the effects on appetite and energy intake. It has also been shown to increase metabolism of dietary fats. These trials suggest that Cayenne may help in the treatment of obesity.

White Willow: grows primarily in central and southern Europe and contains the parent compound from which aspirin was created. It is traditionally used as a pain medication.

Vitamin B6: is the master vitamin for processing amino acids and the building block of all proteins and some hormones. Vitamin B6 is an essential nutrient in the regulation of mental process and mood. It has been know to improve glucose tolerance

Green Tea: is used as a social and medicinal beverage. It has been used in traditional Chinese medicine to reduce pain, enhance immunity, and as an energizer to prolong life. Green Tea has been used in connection with weight loss and immune function. It has also been shown to lower cholesterol levels and blood pressure.
