Comparison between yohimbe bark and green coffee bean in weight loss
Yohimbine is an indole alkaloid derived from the bark of the Pausinystalia yohimbe tree in Central Africa.
Yohimbe bark extract for weight loss
Yohimbine has shown to increase lipolysis in multiple studies.
Administered prior to exercise, it boosts lipolysis and serum FFA levels both during and following exercise; blockade of adipocyte alpha-2 adrenoreceptors makes at least a modest contribution to this pro-lipolytic activity. Pre-exercise yohimbine administration has the potential to down-regulate the lipoprotein lipase activity of visceral adipocytes, increase lipolysis in refractory gynoid fat depots, and improve the impaired lipolytic response to exercise in the elderly.
Combining yohimbine with stimulants such as caffeine and/or ephedrine could possibly further increase lipolysis due to the potential for yohimbine to increase catecholaminergic stimulant activity.
Green coffee bean extract is made from the unroasted beans of Coffea Arabica L., and results in a high level of Chlorogenic acid and other caffeoylquinic acids.
Green coffee bean extract for weight loss
Green coffee bean extract helps to release fatty acids from stored body fats, as well as aid the liver in dispensing fatty acids, which help burn off the excess fat the body has.
The effect of chlorogenic acid enriched coffee on glucose absorption in healthy volunteers and its effect on body mass when used long-term in overweight and obese people.
J Int Med Res. 2007. Thom E. ETC Research and Development, Oslo, Norway.
The results from a clinical study performed in 12 healthy volunteers with different coffee products containing glucose show that instant coffee enriched with chlorogenic acid induced a reduction in the absorption of glucose of 6.9% compared with control. No such effects were seen with normal or decaffeinated instant coffee. In a second, comparative, randomized, double-blind, 12-week study we investigated the effect on the body mass of 30 overweight people, compared with normal instant coffee. The average losses in mass in the chlorogenic acid enriched and normal instant coffee groups were 5.4 and 1.7 kg, respectively. We conclude that chlorogenic acid enriched instant coffee appears to have a significant effect on the absorption and utilization of glucose from the diet. This effect, if the coffee is used for an extended time, may result in reduced body mass and body fat when compared with the use of normal instant coffee.
Besides,
resveratrol also has the funtion of losing weight. Resveratrol is a polyphenolic compounds , mainly from grapes ( red wine ) , knotweed , peanuts, mulberry and other plants . Resveratrol is a natural biological strong polyphenols , also known as Qi three phenol, is cancer chemopreventive agent , but also to reduce platelet aggregation, prevention and treatment of atherosclerosis , cardiovascular and cerebrovascular diseases chemopreventive agent.
