Question
List the factors that determine energy requirement in human beings
Answer
The energy requirement in human beings is influenced by a combination of factors that vary from person to person. Energy is needed to maintain basic physiological functions, support physical activity, and carry out various bodily processes. Here are some key factors that determine energy requirement in human beings:
a) Basal metabolic rate (BMR): BMR represents the energy expended by the body at rest to maintain basic functions such as breathing, circulating blood, and maintaining body temperature.
b) Occupation/activity: The level of physical activity plays a significant role in energy requirements. More active individuals expend more energy.
c) Body size / Muscle Mass: Individuals with higher muscle mass generally have a higher overall energy expenditure.
d) Age: Children and adolescents, for instance, have higher energy requirements due to growth and development, while energy needs tend to decrease with age in adulthood
e) Lactation and pregnancy: Pregnant and breastfeeding women have increased energy requirements to support fetal development and milk production.
