Question 1

What is TDEE?

Accepted Answer

TDEE (Total Daily Energy Expenditure) is the total energy your body burns in a day, at rest and in activity. It's your “maintenance” — eating at that level keeps your weight stable.

Question 2

How is my basal metabolism calculated?

Accepted Answer

We use the Mifflin-St Jeor equation (1990), the most validated one for healthy adults. It estimates your basal metabolic rate from your sex, age, height and weight, then multiplies it by your activity level to get your TDEE.

Question 3

Why a calorie deficit or surplus?

Accepted Answer

To lose fat you aim for a deficit (eating below maintenance); to build muscle, a slight surplus. The calculator applies a default adjustment based on your goal — a sensible starting point to refine from your results.

Question 4

What are macros?

Accepted Answer

The macronutrients: protein, carbs and fat. Their split matters as much as the calorie total — especially protein, which preserves muscle. We suggest a split tailored to your goal and body weight.

Question 5

Are these numbers 100% accurate?

Accepted Answer

They are science-based estimates, not absolute truth: your real metabolism varies. Use them as a starting point, measure your results over 2 to 3 weeks, then adjust. That's exactly the work a coach does with you on Adhérence.
