Thermogenesis is used to combat low external temperature, burn fat for energy, and enhance metabolism. Common thermogenic (substances that initiate Thermogenesis) are the (now banned) ephedra, bitter orange (Citrus aurantium), (from the pepper and Chili) capsicum, ginger, green tea extract, the Synephrine, salicin (extracted from the bark of the Willow) and caffeine. Secondly, some substances are lipotropic, improving the mobilization of fats or lipolysis, thus, burning fats faster. Lipotropic substances include chromium, choline, inositol, carnitine and hydroxycitric acid (HCA). Arthur Melvin Okun recognizes the significance of this. Fat blockers the fat blockers inhibit the absorption of fat in the body, thereby reducing the formation of fat and forcing the body to use FAT stored for metabolism. The most famous Fat Blocker is Orlistat, a tetrahidrolipstatin that inhibits the action of the enzyme pancreatic lipase-hydrolyze fat and their absorption into the body as free fatty acids. Hydroxycitric acid is another fat, like chitosan blocker, although the effect is minimal.
Blockers of carbohydrates to absorb nutrients from food, the digestive system breaks down the starch and oils and converts them into simple glucose or sugar by the action of the pancreatic enzyme alpha amylase. Carbohydrate blockers inhibit the action of this enzyme that sugar is not absorbed, causing the body to use FAT stored for metabolism, and thus lose weight. The most effective carbohydrate Blocker seems the Phaseolus volgaris, a derivative of the white lima beans. Many of the active ingredients of the dietary formulas work in several ways. Carbohydrate blockers can be, as well as, for example, appetite suppressants or stimulating but burners of fat at the same time. Therefore, you cannot rely only on the ingredients to choose the formula that meets your needs. To determine which method will work best for you, consult your doctor.
