The effects of additional weight on a person's body are dramatically demonstrated with this useful teaching tool, which simulates the "look" and "feel" of excess body fat. By inserting weights in varying increments into the vest's interior pocket, the wearer can experience the additional weight and limited range of motion that are associated with obesity. Two versions are available. The adult version, which includes a total of 20 lb of weight (three 5-lb weights and two 2 ½-lb weights), features a colorful and informative front panel that describes the effects of excess weight on several body organs. An excellent way to start group discussion about healthy eating habits.
