09 Sep 2015 --- Many people eat whilst on the move especially those with busy work schedules. But new research from the University of Surrey has shown that eating whilst walking could actually trigger weight gain in dieters. The research was published in the Journal of Health Psychology and suggested that people who ate whilst walking were more likely to eat more later on in the day. Studies have already shown that eating whilst watching TV or looking at a computer may lead to over-eating, but walking is even worse it seems.
