Eating on the run is basically burning calories off while you intake them, right? As great as that concept sounds, it really is too good to be true according to a recent study.

Researchers split 60 female volunteers into three groups and had them eat a cereal bar under three different scenarios: walking, talking to a friend and watching a TV clip. They were then given a taste test featuring an array of snacks ranging from salty to sweet. They were allowed to eat as much of these as they’d like.

They found that participants who ate the cereal bar while watching the TV clip ate less during the taste test. But women who ate the bar while walking indulged in a significantly greater amount during the taste test. They speculate that our bodies don’t register snacking on the go as eating and may even associate it with exercise! Best way to prevent this? Make a conscious effort to focus solely on eating without distraction.
