Anyway, that evolution hasn’t sprung out of the gene pool in 50 or 100 years only, it takes a lot more than that for human genes to evolve (otherwise, we’d all be fit by now for processed foods and McCrap’s). If our ancestors could deal with it because they were used to periods of food scarcity, then it tells me much already about the problem that is food in our modern age. We very likely need to be aware of that, and go on paying attention to eating healthier foods, rather than mop around moaning about ‘it’s all in my genes’.

I think it might apply particularly well if the “thrifty gene” really does exist. Perhaps it will explain why some of us have a greater tendency to be bulky or to retain fat — but it isn’t an excuse for accepting it and giving up on being healthy, which at the end of the day is a slightly different thing.

There are plenty of unhealthy thin people around after all
