Question 1

What is BMR (Basal Metabolic Rate)?

Accepted Answer

Basal Metabolic Rate (BMR) is the total number of calories that your body needs to perform basic, life-sustaining functions. These basal functions include circulation, breathing, cell production, nutrient processing, and protein synthesis. It's essentially the calories you would burn if you stayed in bed all day doing absolutely nothing.

Question 2

What is the difference between BMR and TDEE?

Accepted Answer

While BMR is your resting metabolic rate, Total Daily Energy Expenditure (TDEE) factors in your physical activity. TDEE is calculated by multiplying your BMR by an activity multiplier (ranging from 1.2 for sedentary to 1.9 for extra active). TDEE represents your "maintenance calories"—the exact amount of calories needed to maintain your current weight.

Question 3

Which formula is used to calculate BMR?

Accepted Answer

We use the Mifflin-St Jeor equation. According to the American Dietetic Association, it is considered the most accurate and reliable formula for calculating basal metabolic rate in modern populations, outperforming the older Harris-Benedict equation.

Question 4

How should I use this data for weight loss or muscle gain?

Accepted Answer

Once you know your TDEE (maintenance calories) from the right panel, you can adjust your intake based on your goals. For weight loss (cutting), subtract 300-500 calories from your TDEE. For muscle gain (bulking), add 200-500 calories to your TDEE. Never consume fewer calories than your BMR without medical supervision.
