People who know about these sorts of things tell me there is a new, awesome, fashionable weight-loss regime out there called the Paleo Diet, in which you go back in time to evolve forward by eating the sort of stuff our cave-dwelling ancestors would have eaten. If you have seen, of late, packs of furrowed-brow, Lycra-clad hominids walking close to the ground in the vicinity of your nearest Les Mills, looking for wildebeest to club and kill, then they are probably on the Paleo Diet.
While I can admire the Paleo Diet on some levels, primarily the level where it lets you eat meat - and I am a man therefore meat is my favourite food group - I struggle with it elsewhere. Take the word "paleo", for example; how paleo do you actually mean? Has fire and, therefore, cooking been added to our cave-dwelling knowledge-base? Or are we expected to find, kill and eat our lamb kebab in the raw? Because I am definitely not keen on that, I'm afraid.
Also I'm a bit confused about the philosophy behind the Paleo Diet wherein, as I understand it, everything we did to food after learning how to put cattle in fenced-off areas and grow vegetables and bake bread and all that processing stuff, was apparently somehow us marching down the road to evolutionary Armageddon. Please, paleo-people, don't also tell me that turning grapes into wine and then putting it in bottles was a bad thing, because then my reason for being has gone altogether.
And then there's something called the 5:2 Diet, where I am told you eat normally (whatever that is these days) for 5 days a week and for the other 2 days you eat only air or birdseed or something along those lines. Apparently this kickstarts some kind of weight-loss imperative in the body, presumably in the same way that water-boarding kickstarts a torture victim into talking or whipping a race-horse makes it run faster.
Dieting through fear on a molecular level might be another way of looking at the 5:2 Diet.
