The Horizon series, "The Right Diet for You" is worth a look. The second episode of ran an experiment. They allowed one group of five participants to go to sleep at the regular time. The other group, however, were asked to stay awake until 3.00am.
Next morning, both groups were asked to complete a shopping task, to buy four different, things, for example, a snack for yourself right now, a pre-packaged dinner, a meal for a family of four, etc. The time was restricted to 20 minutes and they were restricted to an amount of money.
You can guess, that the group who were sleep deprived shopped unwisely. However, the scale is gob smacking. The group who were sleep deprived bought food which contained 50 per cent more fat, sugar and salt.
WE SHOULDN'T SHOP WHEN WE ARE TIRED.
Be nice...
The program recommended that if we must shop at the end of a long working day, make a list the day before, when you are not tired.....
