Metabolic Rate

Definition

Metabolic rate is the speed at which your body uses energy or burns calories to maintain vital functions and everyday activities.

Scientific / Technical Definition

Metabolic rate refers to the rate at which the body expends energy or burns calories. This process is crucial for maintaining essential physiological functions such as breathing, circulation, cell production, and temperature regulation. The total energy expenditure is determined by several factors, including basal metabolic rate (BMR), thermic effect of food (TEF), and physical activity level (PAL).

Benefits

• Helps regulate weight by balancing calorie intake and expenditure.
• Supports essential bodily functions such as respiration, circulation, and digestion.
• Influences energy levels and stamina throughout the day.

Examples

• Basal Metabolic Rate (BMR) measurement at rest.
• Total Daily Energy Expenditure (TDEE) calculated to plan a diet or fitness regimen.

Additional Information

• Effects: Metabolic rate affects how quickly or slowly your body converts food into energy, impacting energy availability for physical activity and growth.
