Step 1
Discuss three factors which effect a person's daily energy requirement.
Answer
There are several factors that affect a person's daily energy requirement:
-
Age: Energy needs vary with age due to physiological changes. For instance, children and teenagers require more energy for growth and development, while older adults may require less due to a slower metabolism.
-
Gender: Males generally have a higher muscle mass compared to females, which results in a higher basal metabolic rate (BMR) and consequently an increased energy requirement.
-
Level of Activity: Individuals who have a more physically demanding lifestyle or engage in regular exercise will require more energy compared to those with a sedentary lifestyle.

-
Balanced meals: Each meal should include a mix of carbohydrates, proteins, and healthy fats to maintain energy levels and support bodily functions.
-
Regular meal times: Regularly spaced meals help to maintain energy levels and prevent energy dips throughout the day.
-
Hydration: Adequate fluid intake is essential; aim to include water or other hydrating beverages in daily routines.
