  • As one example, Dr. Wansink gave away five-day-old popcorn to moviegoers.Some people receivedenormous buckets while other received smaller ones. Both sizes held more popcorn than a typical person could finish.Yet when the buckets were weighed after the movie, those with the bigger buckets ate an average of 53 percent more.
  • If you downsize your portion size and feel a smaller portion looks too small … serve it on a smaller plate so it looks larger. Note the difference in the appearance of one cup of cereal when a smaller bowl is used. Using a smaller plate or bowl also can help you eat less according to research by Professors Brian Wansink and Koert van Ittersum. Larger plates can make a serving of food appear smaller. For example, in a study conducted at a health and fitness camp, campers given larger bowls consumed 16% more cereal than those given smaller bowls. Their estimates, however, were 7% lower than the estimates of those eating from the smaller bowls.
  • The Nutrition Facts label on this 20-oz. beverage bottle it lists the number of calories in an 8-oz. serving (100) even though the bottle contains 20 oz. or 2.5 servings. To figure out how many calories are in the whole bottle, you need to multiply the number of calories in one serving by the number of servings in the bottle (100 x 2.5). You can see that the contents of the entire bottle actually contain 250 calories even though what the label calls a "serving" only contains 100.

    3. 3. IMPORTANT If you plan to use these slides to present to others:  You are welcome to remove any slides you feel aren’t needed by your audience.  MyPlate food amounts are based on a 2,000 calories for ages 19 and over, the calorie level used on a Nutrition Facts panel. The calorie levels for your audience may be higher or lower, based on their calorie needs — adjust or explain accordingly.3 Alice & Amy

Large packages and containers can lead to overeating foods we do not even find appealing.‖ ~ Brian Wansink, PhD, John Dyson Endowed Chair in the Applied Economics and Management Department at Cornell University, and author of “Mindless Eating”4
