Question 1

What is BMR and why does it matter?

Accepted Answer

Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production. It represents the minimum energy required to keep your body functioning at rest.

Question 2

How is TDEE different from BMR?

Accepted Answer

Total Daily Energy Expenditure (TDEE) is your BMR plus all calories burned through daily activities, exercise, and digestion. TDEE gives a more accurate picture of your actual daily calorie needs.

Question 3

Which BMR formula is most accurate?

Accepted Answer

The Mifflin-St Jeor equation is generally considered most accurate for most people. The Katch-McArdle formula is better for lean individuals as it accounts for body mass. Harris-Benedict is the oldest but may overestimate for some.

Question 4

How do I calculate calories for weight loss?

Accepted Answer

To lose weight, create a calorie deficit by eating 300-500 calories below your TDEE. This typically results in 0.5-1 lb weight loss per week, which is considered safe and sustainable.

Question 5

Does muscle increase BMR?

Accepted Answer

Yes, muscle tissue is metabolically active and burns more calories at rest than fat tissue. Building muscle through strength training can increase your BMR over time.

Question 6

How often should I recalculate BMR?

Accepted Answer

Recalculate your BMR whenever your weight changes by more than 10 lbs, or every 3-6 months. Age, body composition changes, and significant weight loss all affect your metabolic rate.
