Explaining how excess calorie intake translates into weight gain is simplified with this graphic and informative display. The plastic jar contains approx 450g of gooey simulated fat, which represents the amount of weight a person would gain in 1 week if he or she consumed an extra 500 calories each day. Information on the back of the jar shows how much weight a person could gain in 1 year as a result of getting extra calories.
