Eating with eyes – Comparing eye movements and food choices between overweight and lean individuals in a real-life buffet setting

Researchers have long sought to pinpoint factors underpinning individual differences in eating behaviour.

However, such studies have thus far relied on food images and computerised tasks, limiting real-world implications.
