Have oversized servings in restaurants distorted our view of what’s normal?

In a recent study, scientists randomly assigned 277 people to be served a lunch with either a larger (440-calorie) or smaller (220-​calorie) portion of quiche.

The next day, the participants were told to serve themselves a portion from a full, family-​sized quiche. (The researchers pretended that the study had some other purpose.)

People who had gotten the larger serving on day one served themselves a larger portion on day two. What’s more, they also chose a larger serving when asked to identify a “normal” portion of quiche that day or a week later.

What to do

Think twice before you eat everything a restaurant serves you. Odds are, you’d feel full with less.
