[33] Metabolic Rate and Basal Metabolic Rate Flashcards
Define metabolic rate.
The speed at which the body uses energy, typically measured in calories per unit of time.
What influences metabolic rate?
- Age
- Gender
- Body size and composition
- Physical activity level
- Hormonal factors
- Genetics
Define Basal Metabolic Rate (BMR).
The rate of energy expenditure at rest in a neutrally temperate environment, in the post-absorptive state.
What is the BMR used to estimate?
The minimum amount of energy required to keep the body functioning at rest.
How is BMR typically measured?
In calories per day.
What factors influence BMR?
- Age
- Body size and composition
- Gender
- Genetic factors
- Body temperature
- Thyroid hormone levels

Basal Metabolic Rate
Why is understanding BMR important?
It can help in developing personalized diet plans, and understanding energy expenditure and weight control.
How does BMR change with age?
It generally decreases as we get older.
How does body size affect BMR?
Larger bodies tend to have higher BMRs.
How does gender affect BMR?
Men generally have a higher BMR than women due to larger muscle mass.
How do genetics affect BMR?
Certain genetic factors can cause variations in BMR.
How does body temperature affect BMR?
Higher body temperature increases BMR.
How do thyroid hormones affect BMR?
Thyroid hormones increase BMR.
What is the difference between metabolic rate and BMR?
Metabolic rate includes all energy expenditure, while BMR is the energy expenditure at rest.
