What is basal metabolism?

• A. The energy burned during physical activity
• B. The calories we burn at rest, without any activity
• C. The energy required for digestion of food
• D. The calories consumed while exercising

Answer: (B)

Basal metabolism refers to the number of calories that your body requires to maintain basic physiological functions while at rest, such as breathing, circulation, cell production, and nutrient processing. This energy expenditure is essential for sustaining life and is measured when you are awake but at rest, in a neutral environment without the influence of recent food intake or exercise. This concept is crucial in understanding the body's energy requirements, as it accounts for a significant proportion of daily energy expenditure, typically around 60-75% in sedentary individuals. This energy is necessary for maintaining vital functions that keep the body operating effectively, independent of any additional activities or exercise.
