Alapanyagcseresebesség

Alapanyagcseresebesség, often abbreviated as AMR or BMR (Basal Metabolic Rate in English), refers to the minimum number of calories your body needs to perform its essential, life-sustaining functions at rest. These functions include breathing, circulation, cell production, nutrient processing, and brain activity. It's the energy expenditure required to keep your body alive and functioning even when you are completely at rest, such as immediately after waking up and before any activity.

The basal metabolic rate is influenced by several factors, including age, sex, body weight, body composition (muscle mass vs. fat mass), genetics, and hormonal activity. Generally, younger individuals and those with more muscle mass have a higher AMR than older individuals or those with less muscle mass. Men typically have a higher AMR than women due to a greater average muscle mass.

Understanding your AMR can be a starting point for calculating your total daily energy expenditure (TDEE), which includes the calories burned through physical activity and the thermic effect of food. While AMR represents the lowest point of energy expenditure, it's a crucial component in understanding an individual's overall metabolic rate and caloric needs for weight management and general health. It is distinct from resting metabolic rate (RMR), which is a similar measure but is taken under less strict conditions than BMR.
