Basal Metabolic Rate (BMR): – BMR is the calories burned at rest, influenced by factors like age, gender, and muscle mass.
Thermic Effect of Food (TEF): – TEF represents energy used in digesting food, with protein having a higher impact.
Physical Activity: – Calories burned through exercise contribute significantly to overall energy expenditure.
Resting Metabolic Rate (RMR): – RMR includes daily activities and is crucial for understanding overall calorie needs.
Muscle Mass Importance: – Muscle burns more calories than fat, making strength training beneficial for metabolism.
Aging Effects: – Metabolism naturally slows with age, but regular exercise can counteract this decline.
Hormonal Influence: – Thyroid hormones, insulin, and cortisol play roles in metabolic regulation and weight management.
