What Is TDEE — And Why Does It Matter for Your Results?

Your Total Daily Energy Expenditure (TDEE) is the exact number of calories your body burns every day — from your metabolism to your workouts, steps, and even digestion.When you know your TDEE, you finally know how your body actually works, which means no more guessing, no more confusion, and no more trial-and-error dieting.

How Your Body Burns Calories (Made Simple)

1. Basal Metabolic Rate (BMR)

The calories your body needs just to stay alive.

This is where most of your calories are burned — even when you’re doing nothing.

2. Daily Movement & Exercise

Steps, workouts, cleaning the house, carrying groceries — it all adds up, and it all affects your results.

3. Thermic Effect of Food (TEF)

Yes, you burn calories by eating.

Protein burns the most — which is why high-protein diets change bodies faster.

  • Katch-McArdle — even more precise if you know your body fat %

Your BMR is calculated instantly, then multiplied by an activity level that reflects your lifestyle. The result?

You get your true daily calorie needs — calculated with precision, not guesswork.
