BASAL METABOLIC RATE (BMR)

WHAT IS BASAL METABOLIC RATE (BMR)?

Your basal metabolic rate (BMR) is the amount of energy your body requires each day while you perform no activity whatsoever, in the form of minimum number of calories needed by your organs to function properly (Including involuntary functions like breathing, pumping blood, keep your heart beating and any other biological process necessary to maintain life) while you are at complete rest. You can think of it as the amount of energy you’d burn if you stayed in bed all day.

WHAT AFFECTS YOUR BMR?

Your BMR mainly is relative to body mass, age, weight, height and gender; as it widely regarded that men need more calories than women. It is also affected by body composition (Ratio of muscle to fat), genetics and hormonal levels; Everyone with a weight problem should have their thyroid function checked by their doctor and treated appropriately if it turns out to be low.

However, increasing muscle mass by regular exercise and balanced diet does increase BMR, because it takes more energy to maintain more muscle. This means that when you have a lot of muscle mass, you’ll burn more calories at rest.

WHY DOES YOUR BMR MATTER?

Once you know your BMR, you can use it to calculate the calories you actually burn in a day. The overall number of calories your body uses on a daily basis is referred to as your Total Daily Energy Expenditure” (TDEE) or “Daily Caloric Needs. It’s determined based on your BMR as well as your activity level throughout the day and HThermogenesis (calories required for heat production). From there, you can determine how many calories you need to eat to gain muscle, lose fat, or maintain your weight.
