The basal metabolic rate accounts for most of our energy needs, about 60-75% of total energy expenditure. … Higher BMR levels result from greater levels of lean body mass. Since males tend to have more lean body mass than women, their BMR is generally higher. BMR can also decrease with age as lean body mass decreases.
How does basal metabolic rate relate to energy?
Basal metabolic rate is the amount of energy per unit of time that a person needs to keep the body functioning at rest. Some of those processes are breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function, and contraction of muscles.
How does metabolism affect energy balance?
Metabolism is the process by which your body converts consumed food and beverages into a source of energy. Energy balance refers to the relationship between calories taken into the body and calories being used in the body (i.e., physical activity) for our daily energy requirements.
What factors affect energy balance?
These include keeping the heart beating and organs functioning, maintenance of body temperature, muscle contraction and growth. However, daily energy requirements vary widely from one individual to the next. This is due to factors such as sex, body size, bodyweight, climate and physical activity levels.
What is basal metabolic rate and its significance?
resting metabolic rate. Basal metabolic rate (BMR) is often used interchangeably with resting metabolic rate (RMR). While BMR is a minimum number of calories required for basic functions at rest, RMR — also called resting energy expenditure (REE) — is the number of calories that your body burns while it’s at rest.
What is considered a good BMR score?
Most men have a BMR of about 1,600 to 1,800 kCals a day. Most women have a BMR of 1,550 kCals a day.

What happens when our energy requirements are not balanced?
Any imbalance between the intake and utilization of these macronutrients will lead to an alteration in body composition. The energy stored per unit body weight of carbohydrate, fat, and protein varies considerably, especially when accounting for the associated intracellular water.

Energy Balance in Real Life
- Drink water instead of a 12-ounce regular soda.
- Order a small serving of French fries instead of a medium , or order a salad with dressing on the side instead.
