1. Resting metabolic rate (RMR) or basal metabolic rate (BMR), which equals sleeping metabolic rate (SMR) and arousal.
2. The thermogenic effect of food.
3. Exercise, or daily physical activity and spontaneous physical activity (SPA).
Weight is determined by the balance between energy intake and energy expenditure. When energy intake exceeds expenditure, the excess energy is stored as fat, leading to weight gain. On the other hand, if energy expenditure exceeds intake, the body uses stored energy reserves, resulting in weight loss. Maintaining a balance between energy intake and expenditure is crucial for weight management.
Net energy expenditure is more important because it represents the energy that is actually available for the body to use after accounting for energy lost as heat during metabolism. Gross energy expenditure includes all energy expended, both useful and wasted, providing a less accurate picture of the body's true energy needs. Focusing on net energy expenditure helps in understanding how much energy is actually available to fuel physiological processes and activities.
One watt of energy expenditure burns approximately 4.18 calories.
The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed. It consists of three components: the total energy in a closed system remains constant, energy can change forms from one to another, and the total amount of energy in the universe is fixed.
The term EFFICIENCY is defined as useful work, divided by total energy expenditure.
The largest contributor to energy expenditure in adults is the basal metabolic rate (BMR), which accounts for approximately 60-75% of total energy expenditure. BMR represents the energy required for maintaining essential physiological functions at rest, such as breathing, circulation, and cell production. Other components of energy expenditure include physical activity and the thermic effect of food, but BMR remains the predominant factor.
Thermogenic effect
Yes, the expenditure components can be negative. This can be so if their value exceeds the amount of money that the owner has.
The body's resting rate of energy expenditure is known as the basal metabolic rate (BMR). BMR represents the energy required to maintain basic physiological functions while at rest, such as breathing, circulating blood, and regulating body temperature. It accounts for the largest portion of total daily energy expenditure.

Energy expenditure is that amount of calories that someone uses in one day by exercising or doing everyday tasks.
55 - 75% of daily energy expenditure
One watt of energy expenditure burns approximately 4.18 calories.
