Hoodia is a pure and natural weight loss supplement and a natural appetite suppressant.
This cactus, grown in Africa's Kalahari Desert, has traditionally been eaten by the San Bushmen, which is a very poor tribe, to ward off hunger on long journeys. South African scientists discovered in their research of this plant that it contained a previously unknown molecule, which they named P57.
This molecule affects nerve cells in the hypothalamus - the part of the brain that controls appetite by responding to levels of blood glucose. P57 signals to the hypothalamus to curb eating. Clinical trials have shown that eating a piece of hoodia about the size of half a banana curbed the appetite for up to 24 hours even after being encouraged to eat.
