What is the Meaning of Energy Expenditure?

The total amount of energy, typically measured in kilocalories, that an organism uses over a specified period to maintain bodily functions, digest food, and perform physical activity. It is a critical component of energy balance dynamics.

What is the Origin of Energy Expenditure?

This concept stems from physics and thermodynamics, where 'energy' is the capacity to do work, and 'expenditure' denotes the act of using or spending.

What is the Mechanism of Energy Expenditure?

Total energy expenditure comprises three main components: basal metabolic rate (BMR), which is the energy required for basic life support, the thermic effect of food (TEF), and physical activity energy expenditure. Thyroid hormones and catecholamines act as key endocrine regulators, directly influencing the BMR by dictating the metabolic rate of tissues like skeletal muscle and liver. Understanding this balance is vital for weight management and metabolic health.
