I sometimes can't resist the lure of takeaway pizza.

study suggests we're not born craving unhealthy food, but it's a learned trait that can be changed. Researchers studied how 13 overweight adults reacted to pictures of healthy and unhealthy meals. Some were given a special high-fibre and protein diet that stopped hunger and food cravings. Brain scans showed the dieting adults had an increased reaction in the brain's ‘reward centre' when they looked at pictures of healthy food, suggesting they had learned to like it.

But the study was so small I wonder if it really reflects most people's appetites.
