Having stuffed yourself silly over Christmas you can now ponder some of Karl Lagerfeld’s best horticulturally-related diet tips. Lagerfeld famously lost six and a half stone a few years ago on a severe regime using the appetite suppressant Hoodia, which is derived from a south African desert plant. Hoodia leaves have been chewed for hundreds of years by African bush hunters, who use the plant to stave off hunger pangs on long hunting expeditions. Now, Hoodia plants are more likely to be guzzled by anorexic New Yorkers in desperate pursuit of size zero. Anyway, it worked for Karl.
However, there is a downside. The Royal Botanic Gardens at Kew has warned that diet enthusiasts have pushed the species to the edge of extinction in its native Botswana. That's why they are stockpiling seed in the Millenium Seed Bank, a nice place for a feel-good winter visit, and a hike through Wakehurst Place's windy paths at the same time will definite burn off a few calories without you having to despoil further the Southern African bush.
