14.3 - Exercise And Weight Management

Energy Balance

The principle of matching energy intake with energy output to maintain a healthy body weight.

Energy Equation

The relationship expressed as Energy storage = Energy intake - Energy output, showing the balance of energy in the body.

Food Calorie

A kilocalorie representing the energy produced by food when processed by the body.

Energy Nutrients

Carbohydrates (4 cal/g), proteins (4 cal/g), and fats (9 cal/g) provide calories in varying amounts.

Daily Caloric Need

The amount of calories required to maintain energy balance and current body weight, influenced by basal metabolic rate and activity level.

Metabolic Rate

The energy needed for essential bodily functions like heartbeat and breathing.

Basal Metabolic Rate (BMR)

The metabolic rate measured under strict conditions, reflecting the energy needed at rest.

Resting Metabolic Rate (RMR)

An estimate of metabolic rate under less rigorous conditions.

Harris-Benedict Equation

An equation to estimate RMR based on weight, height, and age, with slight variations for males and females.

Daily Caloric Need Calculation

A method to estimate daily caloric needs by multiplying RMR by an activity factor based on activity level.
