The Energy Equation The calories you consume must equal the calories your body burns.
Calories- Units of heat that measure the energy used and energy that food supplies the body 1 pound=3,500 calories.
3,500 calories less a week and you'll lose 1 pound.
500 calories a day X 7 days= 3,500 calories. fewer calories than you burn=lose weight
more calories than you burn=gain weight Determining your appropriate Weight Range influenced by several factors
body frame
growth rate
metabolic rate
activity level Body Mass Index A ratio that allows you to assess your body size in relation to your height and weight. Teens grow at different rates and in different ways. There is no single size, shape, or growth pattern that's normal for everyone. BMI=Weight X 703/Height squared Body Composition the ratio of body fat to lean body tissue. 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 Health Risks Adults with high BMI's are at increased risk for
cardiovascular disease
