TDEE Calculator

Lean adjusts your daily energy expenditure based on your metabolism, step count, workouts and your eating habits.

Get a personalized daily calorie expenditure tailored to your body and activity.

Here’s how your body works:

Your daily expenditure, also called TDEE In scientific literature for Total Daily Energy Expenditureis the energy your body expends over the course of a day.

TDEE is made up of four components:

Your BMR – Basal Metabolic Rate : The energy your body uses at rest — this is your metabolism.
Your NEAT – Non-Exercice Activity Thermogenesis : The energy your body expends through daily movements like walking, standing, brushing your teeth, etc.
Your EAT – Exercice Activity Thermogenesis : The energy used during physical activity such as strength training, running, or cardio workouts.
Your TEF – Thermic Effect of Food : The energy your body uses to digest and process the food you eat.

Lean calculates all four components with high precision to give you the most accurate possible estimate of your daily calorie expenditure.

You provide your body with energy through nutrition.

Your BIG Problem with Other Calorie Tracking Apps

Apps like MyFitnessPal, YAZIO, Lifesum, and many others DO NOT actually calculate your energy expenditure. They rely on rough, outdated estimations:

Elles calculent un métabolisme de base avec des modèles old or inaccurate models ❌
Then apply a generic activity multiplier to estimate your BMR ❌

Fatal error on MyFitnessPal: applying an extremely inaccurate activity factor to determine daily energy expenditure.

This error is irreparable: an activity factor is extremely inaccurate. In case you didn’t know:

Not very active: BMR x 0.5
Moderately active: BMR x 1
Active: BMR x 2
Very active: BMR x 3

These calorie expenditure estimates are far too imprecise to be taken seriously.

If the calculated calorie expenditure is arbitrary, then the recommended calorie intake is also arbitrary.

Result: it's nearly impossible to achieve good long-term results using other calorie tracking apps. And as proof...

71% of Lean users have previously used another calorie tracking app.

If the majority of Lean users were already using calorie tracking apps in the past, it’s not a coincidence:

Lean place tous ses efforts into calculating your daily energy expenditure as accurately as possible..

Because to reach your goals, it’s crucial to know both your calorie intake and your energy expenditure precisely.And unfortunately, that’s the major issue with other calorie tracking apps: energy expenditure is consistently inaccurate.

That’s why Lean precisely calculates the four components of your body’s energy expenditure — BMR, NEAT, EAT, and TEF — to accurately determine your TDEE:

Lean constantly recalculates your daily energy expenditure (TDEE) in real time — based on your activity (step count, workouts, weight & body fat, and food intake).

TDEE Evolution Throughout the Day in Lean

Lean truly helps you reach your daily goal by precisely calculating both your energy expenditure and your calorie intake.

FAQ

How to Easily Increase Your TDEE?

Increasing your TDEE with Lean is simple: since TDEE is made up of four components, you'll need to optimize each one:

BMR Your Basal Metabolic Rate is heavily influenced by your muscle mass. Strength training will help you build more muscle over time, which increases your BMR. You can gain between 200 to 500 kcal per day over a few years of consistent training.
NEAT Non-Exercise Activity Thermogenesis can be significantly increased by adopting habits that involve more daily movement (like walking more). NEAT is the most powerful lever for increasing TDEE — you can easily boost your daily expenditure by up to 1000 kcal per day.
EAT : La réalisation d’exercice vous permettra de facilement brûler des calories et augmenter votre dépense quotidienne.
TEF The Thermic Effect of Food is highest for protein. A high-protein diet can help you burn an additional 100 to 200 kcal per day.
