The human body is a remarkable food processor. As an adult, you may consume over a ton of food per year and still not gain or lose a pound of body weight. You are constantly harnessing, and consuming energy through the intricate mechanism of your body in order to remain in energy balance. To maintain a given body weight, your energy input must balance your energy output. However, sometimes the overall energy balance is upset, and your normal body weight will either fall or increase. The term body image refers to the mental image we have of our own physical appearance, and it can be influenced by a variety of factors, including how much you weigh or how that weight is distributed.
