The weight loss industry is notorious for the multitude of sensational claims it makes. This applies especially to supplements and pills that offer quick fixes with very little effort. While most fail to deliver, a number of products stand out as capable of improving fat burning in the body, all operating in a number of ways.
Yohimbine Hydrochloride
Traditional healers have used yohimbe, a herb native to Africa, as a tool to ward off fatigue and to improve fat burning and sexual stamina. Manufacturers offer the herb, an alpha blocker, in the form of yohimbine hydrochloride. Muscle Science explains how each fat cells has both alpha and beta receptors and that the job of the former involves the downregulation of fat burning. Alpha blockers like yohimbine hydrochloride can help overcome this unwanted regulation and help burn more fat, especially around the abdomen and hips, as these areas possess more alpha receptors.
Sida Cordifolia
Used for centuries to counter the effects of asthma and bronchitis, sida cordifolia operates in a different way by stimulating beta cells across the body. These cells cause the relaxation of smooth muscle in the respiratory tract but increase the rate of fat burning in the fat cells. Normally, such agents can cause a noticeable stimulant effect in the cardiovascular system also, although Nutritional Reviews point out that studies on the herb found that no elevation of heart rate occurred in volunteers that took it. However, despite positive anecdotal reports, they also point out that very little evidence currently exists supporting the use of sida cordifolia to increase weight loss.
Green Tea
The evidence supporting the use of green tea as a fat burning agent has increased in recent years. The fat burning effect remains whether consuming the drink or using green tea extracts, with researchers identifying the catechins as the active ingredient. The catechins increase the availability of noradrenaline throughout the body, which in turn stimulates more fat burning. French academics investigated the use of a green tea extract on body composition in volunteers in 2002. Their study, published in the "Phytomedicine" journal, showed that three months use of the extract triggered an average drop in bodyweight of 4.5 percent and a reduction in waist size of 4.6 percent.
