Question 1

What is the difference between BMR and TDEE?

Accepted Answer

BMR is the energy your body needs just to stay alive at complete rest. TDEE accounts for digestion, daily movements, and physical exercise.

Question 2

Why is Mifflin-St Jeor considered the gold standard?

Accepted Answer

Multiple clinical trials show Mifflin-St Jeor achieves the highest accuracy in healthy non-obese and obese adults when body fat is not measured directly via DEXA.

Question 3

How large should my calorie deficit be to avoid muscle loss?

Accepted Answer

A 15% to 20% deficit allows steady fat loss (0.5–1% of body weight per week) while keeping performance and muscle retention intact when paired with high protein.
