Participants in a study were asked to estimate the calories in a dish of ice cream. Topping the sample scoop with fresh strawberries reduced participants’ estimates from 481 calories to 405. Don’t fall into this trap. To help counteract the false impression caused by fruit, decide ahead of time that you’ll eat just half of any dessert you choose. Or, to give yourself a reality check, ask yourself: “Would I feel good about ordering this dessert if it weren’t covered in fruit?” If not, reconsider your selection—or ask if you can have a dish of just the fruit topped with a swirl of whipped cream.
