1. What is TDEE for Bariatric Patients?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day, including basal metabolic rate and physical activity. For bariatric patients, accurate TDEE calculation is essential for proper nutritional management and weight loss/maintenance planning.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation with activity factor:

\[ TDEE = (10 \times weight + 6.25 \times height - 5 \times age - 161) \times activity\ factor \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
\( activity\ factor \) — Multiplier based on physical activity level

Explanation: The equation calculates basal metabolic rate (BMR) and then multiplies by an activity factor to estimate total daily energy expenditure.

3. Importance of TDEE Calculation

Details: Accurate TDEE estimation is crucial for bariatric patients to determine appropriate caloric intake for weight management, prevent malnutrition, and support optimal recovery and health outcomes.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age in years, and select appropriate activity factor. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: Why is TDEE calculation important for bariatric patients?
A: Bariatric patients have specific nutritional needs and TDEE helps determine appropriate caloric intake for weight management and preventing complications.

Q2: How often should TDEE be recalculated?
A: TDEE should be recalculated every 4-6 weeks or after significant weight changes to ensure accurate caloric recommendations.

Q3: What activity factor should bariatric patients use?
A: Most bariatric patients should use sedentary or lightly active factors unless they have specific exercise routines approved by their healthcare team.

Q4: Are there limitations to this calculation?
A: This calculation provides an estimate and may need adjustment based on individual metabolic factors, medications, and specific bariatric procedure.

Q5: Should protein intake be considered separately?
A: Yes, bariatric patients require higher protein intake (typically 60-80g/day) which should be prioritized within the total caloric budget.
