Walking is thought to distract the brain, so it does not remember eating and wants more
Researchers from the University of Surrey found eating while walking around triggered more overeating compared to eating during other forms of distraction such as watching TV or having a conversation with a friend.
The asked 60 women to eat a cereal bar while either walking down a corridor, watching the sitcom Friends or chatting to a friend.
After the experiment the participants completed a follow-up questionnaire and a taste test involving four different bowls of snacks, includingchocolate, carrot sticks, grapes and crisps. How much they ate was measured after they left the room.
The results showed that dieters ate more snacks at the taste test if they had eaten the initial cereal bar whilst walking around and specifically they ate five times more chocolate.
“Eating on the go may make dieters overeat later on in the day,” said lead author Professor Jane Ogden from the University of Surrey.
