The relationship between metabolism and physical activity levels is interconnected; higher levels of physical activity increase metabolic rates. Regular exercise elevates caloric expenditure, promoting weight management and overall energy balance. Furthermore, increasing lean muscle mass through resistance training can enhance basal metabolic rate, allowing the body to burn more calories at rest. Conversely, a sedentary lifestyle may lead to decreased metabolism, making it more challenging to maintain a healthy weight. Staying active is essential for optimizing metabolic health.
