                                Over 60% of an individual's total daily energy expenditure is composed of their resting metabolic rate, making it a critical component for health and weight management. A precise technique for measuring this, along with energy expended during physical activity, involves analyzing the gases exchanged during respiration to estimate total calorie burn.
