Body Image and Weight-Calorie Connection

Body Image: The way you see your body.

Maintaining weight is a matter of energy balance. The calories you consume must equal the

calories you burn. If you eat more than you burn=gain weight. If you burn more than you eat=lose weight.

Determining Your Healthy Weight Range

Body Mass Index or BMI: A ratio that allows you to assess your body size in relation to your height and weight.

During the teen years, individuals grow at different rates and in different ways. There is no single size, shape, or growth pattern that is normal for everyone.

Overweight vs. Obesity

Overweight: a condition in which a person is heavier than the standard weight range for his or her height.

Obesity: having an excess amount of body fat.

Weight Related Risks

Overweight Strains the muscular and skeletal system Forces the heart and lungs to work harder Increases risk of high blood pressure, high

cholesterol, type 2 diabetes, asthma, and some cancers.

Underweight: a condition in which a person is less than the standard weight range for his/her height. Not getting enough nutrients may lead to fatigue,

decreased ability to fight illness.
