Knowledge about calories hardly changes eating habits
Knowledge but no action
A second experiment made clear that the test subjects did adjust their behaviour somewhat when different foods were combined. Students who first ate a low-calorie pudding took larger helpings of the next dish than those who ate a more substantial pudding first. But this adaptation hardly compensated for the difference: the ‘high-calorie group' still ate over 500 calories more.
So eating habits seems to be hard to influence. 'It seems we do learn', says Hogenkamp, ‘but we do not act on the new information.' The PhD researcher defends her thesis on 13 January.
