Could exercise really make us want healthier, low-calorie food?

Could exercise really make us want healthier, low-calorie food?

When scientists talk about diet and exercise they generally relate today’s problems to things that made sense in the past. For instance, we’re attracted to sugar because sweeter berries were less likely to give a hunter gatherer an upset stomach. And we’re getting fat because we drive everywhere rather than roaming the plains in search of bison.

So how can this article make sense?

Unless the Daily Mail has got the wrong end of the stick (could that happen, do you think?) it seems that these researchers are suggesting that the harder our ancestors had to work to catch that bison, the more likely they’d be to push it aside in favour of the salad.

It’s a nice, motivating new year thought that sitting around makes you hungrier than moving about but it doesn’t sound like much of a strategy for survival to me.
