Misty is 16 and, with her family, is visiting her grandmother for Christmas. At the end of a week surrounded by tempting holiday food, Misty weighs herself and sees that she has gained five pounds. She confides to her mother that she ate all of a 1-lb box of chocolates on Christmas day, but didn't overeat in any other way. There are 500 kilocalories per 100 g of chocolate. 1 lb = 454 g. There are
3500 kilocalories in a pound of fat. How many calories did she consume? Does this account for the five pounds she gained? Explain.
What will be an ideal response?
She consumed 454 g of chocolates. 454 g × 500 kcal/100g = 2270 kcal. The chocolates cannot account for more than
about 2/3 of a pound. She must have consumed extra calories at her meals and other snacks as well, and she may
have exercised less than normal.
