4 METABOLISM Metabolism converts the fuel in the food we eat into the energy needed to power everything we do. From moving to thinking to growing. The means by which the body releases the energy in food and uses it to build and repair body tissue.

5 Just as a car stores gas in the gas tank until it is needed to fuel the engine, the body stores calories - primarily as fat. If you overfill a car's gas tank, it spills over onto the pavement. Likewise, if a person eats too many calories, they "spill over" in the form of excess fat on the body. The number of calories a person burns in a day is affected by 1) How much that person exercises, 2)The amount of fat and muscle in his or her body, and 3)The person's Basal Metabolic Rate (BMR).

6 BASAL METABOLIC RATE Basal Metabolic Rate, or BMR, is a measure of the rate at which a person's body "burns" energy, in the form of calories, while at rest. BMR is the minimal amount of calories the body needs to survive. The BMR can play a role in a person's tendency to gain weight.

7 FACTORS INFLUENCING BMR To a certain extent, a person's basal metabolic rate is inherited Exercising more will not only cause a person to burn more calories directly from the extra activity itself, but becoming more physically fit will increase BMR as well. People with more muscle and less fat generally have higher BMRs. Why?

12 BASAL METABOLISM The amount of energy needed by the body when it is at rest to carry out basic life functions.

13 Food Provides Energy The amount of energy in food depends on the amount of carbohydrates, fats, and proteins. Extra food energy that you do not use immediately is stored as glycogen or fat. Breakfast provides you with important energy for activating your body and brain at the start of the day.

14 Basal Metabolic Rate Your basal metabolic rate (BMR) is the amount of energy your body uses for basic functions. BMR varies from person to person, depending on age, weight, sex, and how active the person is.

15 Balancing Energy You are in energy balance when the food energy you take in equals the energy you use. Extra food energy increases the body s fat and causes weight gain. Some body fat is essential for health. Overweight people are too heavy for their height. The extra weight is usually due to excess body fat.

16 Being overweight increases the risk of many longterm health problems, including: Heart disease and high blood pressure Prostate, colon, and breast cancer Type 2 diabetes Sleeping problems such as sleep apnea
