What is TDEE?
Total Daily Energy Expenditure is how many calories you burn each day — including exercise, daily movement, and resting metabolism. It's the foundation of any diet plan.
Why macros matter
Hitting your calorie target isn't enough — the right balance of protein, carbs and fat determines whether you build muscle, lose fat or both.
