Chapter 07 Energy Balance

These flashcards cover key concepts related to energy balance, methods of measuring energy use, and factors influencing body weight and composition.

What is energy balance?

Energy balance is the relationship between the calories consumed and calories expended by the body.

What are the three factors that determine energy expenditure?

Basal metabolism, physical activity, and thermic effect of food.

List two components that can lead to positive energy balance.

Increased energy intake and decreased energy expenditure.

Define negative energy balance.

Negative energy balance occurs when energy intake is less than energy output, leading to weight loss.

What dietary pattern is suggested for effective weight management?

A nutrient dense, primarily plant-based, high-fiber dietary pattern combined with regular physical activity.

What is the purpose of measuring body composition?

To assess and classify an individual's body fat and lean mass for health evaluations.

What is Thermic Effect of Food (TEF)?

The increase in metabolic rate after ingestion of food due to the energy required for digestion, absorption, and metabolism.

What does BMI stand for?

Body Mass Index.

What is a healthy BMI range?

A BMI of 18.5 to 24.9 is considered healthy.

What role does physical activity play in weight management?

Physical activity helps create a caloric deficit necessary for weight loss and is essential for weight maintenance.

Explain what adaptive thermogenesis is.

Adaptive thermogenesis is the variation in energy expenditure in response to environmental changes, such as temperature and weight loss.
