kalóriaégetést

Kalóriaégetés refers to the process by which the human body expends energy. This energy expenditure occurs constantly, even at rest, to maintain essential bodily functions such as breathing, circulation, and cell production. This baseline metabolic rate is known as the basal metabolic rate (BMR).

Beyond BMR, additional energy is burned through physical activity. This includes structured exercise, like running or swimming, as well as non-exercise activity thermogenesis (NEAT), which encompasses everyday movements like walking, fidgeting, and standing. The thermic effect of food (TEF) also contributes to calorie expenditure, as the body uses energy to digest, absorb, and metabolize the food consumed.

The number of calories burned varies significantly between individuals based on factors such as age, sex, body weight, body composition (muscle mass burns more calories than fat), genetics, and activity level. Understanding calorie expenditure is fundamental to managing weight, as it is a key component of the energy balance equation, which dictates whether weight is gained, lost, or maintained when compared to calorie intake.
