It's the look everyone wants — a body to diet for. They're on the beaches, in magazines and all over Hollywood. How far will we go to get one? How about thousands of miles and deep into a distant culture? South Africa’s Kalahari Desert is home to what could be the answer to an appetite.

It's a cactus called hoodia. “You strip off the skin, you strip off the spines, and then you consume it,” says weight loss expert Madelyn Fernstrom.

Eat it and you won't want to eat anything else — a secret bushmen have known for ages and a mystery to the West no more.
