Daily Energy Requirements which is the amount of calories that a human should take to perform its typical functions. The Daily Energy Requirements is based on three values: Basal Metabolic Rate (or
BMR), Thermogenesis, Daily Energy Expenditure. The
Basal Metabolic Rate (BMR) is the amount of energy expended daily by humans at rest. Rest is defined as existing in a neutrally temperate environment while in the post-absorptive state. The release, and using, of energy in this state is sufficient only for the functioning of the vital organs.
Thermogenesis is the process of heat production in organisms. It occurs mostly in warm-blooded animals. The
Daily Energy Expenditure, related to physical activity, is the greater variable that changes according to the level of physical activity, the body constitution, sex and age of the person. It happens, particularly in recent times, that an excessive caloric intake respect to the needs involves accumulation of fat and, consequently, increased weight. Conversely, if the individual eats less calories compared their consumption, the body is forced to consume the fat reserves to compensate for the lack of energy; in this case, we see a weight loss.
