Concern with weight and shape is extremely common during the adolescent years. In addition to being exposed to the very real health risks of obesity and poor nutrition, teenagers are being exposed to the unrealistically thin beauty ideal that is portrayed in the media [1]. Unfortunately, this overemphasis on the importance of being thin is internalized by youth who equate thinness with beauty, success and health. Through me­ dia exposure, teenagers are also exposed to a number of ways to lose weight and achieve this thin ideal. The sources of in­ formation available on health and nutrition are often dubi­ ous and unreliable, motivated less by scientific evidence than by fad trends and financial incentives. The net result is that many teenagers feel the cultural pressure to be thinner than is required for good health, and may try to achieve this goal through poor and sometimes dangerous nutritional choices.
