Q

define Basal Metabolic Rate (BMR)

A

The minimum amount of energy that the body uses to maintain vital metabolic functions while at rest. For example: breathing, blood circulation, body temperature regulation, pumping of heart and maintenance of function of brain, liver and other organs.

-Women that experience menstruation at the same age of a man that doesn’t require more iron due to blood loss

17
Q

what is meant by Basal metabolic rate

A

-Those who have a higher BMR use more energy and need more energy input than those with a lower BMR. Teenagers have a higher BMR than adults and seniors.

18
Q

what is meant by Level of physical activity

A

-Individuals who are physically active need a larger energy intake

19
Q

what is meant by Health status

A

-People who are obese or have diabetes need to restrict their calorie and sugar intake. People who are anemic may need to consume more iron-rich food

35
Q

define energy input

A

energy intake is the amount of energy a person obtains from their diet . carbohydrates, fats and proteins contribute to these energy

36
Q

define energy output

A

energy output is the amount of energy a person uses for basal metabolism, thermic effect of food and physical activities

37
Q

define the relationship between energy balance and body weight

A
  • when energy input is balaced with energy output = body weight remain unchanged
    -when energy input is higher than energy output = body weight increases
    -when energy input is lower than energy output = body weight decreases
