What does BMR stand for?

BMR stands for your Basal Metabolic Rate, which is the amount of energy a human body uses when it is completely at rest. It’s the amount of energy your body needs to support its vital functions: breathing, blood circulation, controlling body temperature, brain and nerve functions to name a few.

How much energy am I using each day?

Your BMR accounts for about 60% to 75% of your Total Daily Energy Expenditure (TDEE), depending on your lifestyle and activity level. The TDEE is the total number of calories you burn every day. The rest of your TDEE comes from the physical activities (walking, talking, eating, etc.) and food digestion. Physical activities account for about 20% of your TDEE but can vary a bit depending on how often you exercise for and its intensity. Food digestions (after-meal) and thermogenesis, uses around 10% of your TDEE.

Factors that can affect your BMR.

1. Exercise – The frequency and intensity of your exercise will affect your BMR

2. Age – As you grow up your BMR will increase, but for adults it will begin to decrease

3. Gender – men have a statistically higher BMR than women. The reason is that their fat-free mass is, on average, higher

4. Pregnancy – If you’re pregnant you’re not only providing nutrients for you but also for your baby. You will have to include your baby’s BMR into your BMR
