Metabolic activity is best expressed as a rate because it reflects the speed at which biochemical reactions occur in the body. Rate comparisons provide more accurate insights into how efficiently cells are utilizing energy and nutrients, which is critical for understanding overall metabolic health.
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).
To calculate the metabolic equivalent (MET) for a specific physical activity, you divide the rate of energy expenditure during the activity by the rate of energy expenditure at rest. This gives you a numerical value that represents the intensity of the activity in relation to resting metabolism.

Temperature is not typically used to determine metabolic activity, as metabolism is more directly influenced by factors such as enzyme activity, substrate availability, and hormonal regulation. Temperature can indirectly affect metabolic rate by influencing enzyme function and reaction rates.
Metabolism refers to the rate at which chemical reactions are synthesised in the body.
Metabolic rate is influenced by a variety of factors including age, body composition, genetics, hormone levels, physical activity, and diet. Factors like muscle mass, thyroid function, and stress levels can also impact metabolic rate. Overall, a combination of these factors determines an individual's metabolic rate.
Metabolic rate is typically measured in calories or kilocalories (kcal) per unit of time, often expressed per day (kcal/day). In scientific contexts, it can also be measured in watts, where one watt is equivalent to one joule per second. Additionally, resting metabolic rate (RMR) is sometimes expressed in terms of oxygen consumption, measured in liters of oxygen per minute (L/min).

Exercise increases metabolic rate by stimulating the body to burn more calories to fuel physical activity and repair muscle tissue. This can lead to weight loss and improved overall health.
