Forget those faddish diets: the grapefruit diet, the South Beach diet, the cabbage soup diet, Posh Spice's latest starvation diet. There's only one diet real men need to worry about and that's the Paleo Diet - aka the Caveman Diet - which, in its most basic form, consists of what our hunter-gatherer ancestors would have eaten.
Who says so? Ray Mears. He's qualified to pronounce on such matters because he has spent more than a decade researching what our distant forebears used to survive on. He has also spent weeks in the wild with nothing more to eat than nuts, berries and lean meat. These, he believes, are the key to avoiding illness and premature death associated with our excessive western consumption of refined sugar and carbohydrate.
"Our ancestors were hunter-gatherers who ate a lot of meat and fish. They had a completely different diet from ours today, and if we were still eating that diet, I'm certain we wouldn't be getting as ill," says Mears. "We still have a Stone Age body. We have modern minds, but our brains and bodies still require the same food."
