Looking for a new weight loss plan? Try living on top of a mountain. Mountain air contains less oxygen than air at lower altitudes, so breathing it causes the heart to beat faster and the body to burn more energy. A handful of studies have found that athletes training at high altitudes tend to lose weight. Doctor Florian Lippl of the University Hospital Of Ludwig-Maximilians-university Munich wondered how the mountain air would affect overweight individuals if they weren’t doing any more physical activity than usual.

Lippl and his colleagues invited 20 overweight men to an environmental research station about 300 meters below the summit of Zugspitze, a mountain around 2,970 meters near the Austrian border. They were allowed to eat as much as they liked. The men also gave blood so that researchers could test for hormones linked to appetite and fatness. At the end of the week, the men, whose mean weight starting out was 105kg, had lost on average about l.5kg. The men’s blood pressure also dropped, which the researchers believed was due to weight lost.

Exactly what caused the weight loss is uncertain. Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usual—about 700 calories fewer per day. Lippl also notes that because their consumption was being recorded, they may have been more self-conscious about what they ate. Regardless, eating less accounts for just l kg of the l.5 kg lost, says Lippl. He thinks the increased metabolic (新陳代謝的) rate, which was measured, also contributed to weight loss but cannot separate the different effects with the given data.

Appetite loss at high altitudes could certainly be key, notes Damian Bailey, a physiologist at the University of Glamorgan, UK, who recently lost 11 kg during a 3-month expedition to the Andes in Chile.   

Unfortunately, for the average person there is no treatment that can resemble living at high altitude, says Lippl. The only alternative is hypobaric chamber, which exposes subjects to low oxygen and isn’t practical as a treatment. He says, half- jokingly, “If fat people plan their holidays, they might not go to the sea, but maybe to the mountain.”

With smart phones taking the world by storm, a phone that can only send and receive voictcal1s and text messages may seem like a relic from a bygone age. Yet in East Africa, simple phones like these are changing the face of the economy, thanks to the mobile money services that are spreading across the region. Using the text--messaging function built into the GSM system(全球通) used by most cell phone networks, these services al1ow people without a bank account or credit card to use their/phone as an electronic wallet that can he used to store, send or receive cash.
It works like this: you pay cash to your loca1 agent who then tops up your mobile money account using a secure form of text messaging. That money can be transferred to another person by sending a message to their cell Phone account.
Fur some the system is a lifeline. ''If I didn’t have my mobile Phone, I would be very poor," says Neyasse Neemur, a mother of four chi1dren who lives in northern Kenya. .”Now I can sell fish.” Neemur took up fishing in Ju1y last year, but making money from it was a little tricky, especially as Turkana peop1e do not usually eat fish. A truck from Ethiopia to Tanzania passes through her vi1lage once a week, and she arranged to have the driver transport the fish several hundred ki1ometers south to market in   Kisumu, where relatives sell the fish.
"I get the money transfer immediately.” says Neemur . "Then I can pay for my children to go to school and for vegetables and beans," she adds, "so I don't need to eat fish."
According to the Central Bank of Kenya, payments worth around l billion Kenyan shillings($13 million) per day were transferred through Kenya’s mobile money systems in 2009, equaling the country’s credit card transactions(業(yè)務). The bank expects mobile money transfers to overtake credit cards in 2010.
