Chris Dubelaar from Deakin U, with colleagues from France, Macquarie U and UTS tested health/unhealthy snack consumption to find people will eat more good stuff if portions are bigger. Then again, they do the same for bad snacks. Environment also influences consumption – watching food-focused scenes in a movie reduced the amount subjects ate.

“Portion sizes can strategically be used to influence the consumption of healthy foods; however, any such manipulation needs to be covert where individuals are not subjected to food related cues.” Broccoli burger makers take note.
