Obesity

Flashcards on energy balance, expenditure, and obesity based on lecture notes.

Positive Energy Balance

When energy intake is greater than energy expended, resulting in weight gain.

Negative Energy Balance

When energy intake is less than energy expended, resulting in weight loss.

Energy Expenditure

The energy the body expends to maintain its basic functions and to perform all levels of movement and activity.

Basal Metabolic Rate (BMR)

The minimum energy expended to keep a resting, awake body alive.

Non-Exercise Activity Thermogenesis (NEAT)

Energy burned through movement outside of planned physical activity.

Thermic Effect of Food

Energy used to digest, absorb, transport, metabolize, and store nutrients.

Body Mass Index (BMI)

Subcutaneous Fat
