1. What is TDEE Calculator For Bariatric Patients?

The TDEE (Total Daily Energy Expenditure) calculator estimates daily calorie needs for post-bariatric patients using the Harris-Benedict equation for BMR multiplied by an activity factor. It provides personalized energy requirements for weight management after bariatric surgery.

2. How Does the Calculator Work?

The calculator uses the TDEE formula:

Where BMR is calculated using Harris-Benedict equation:

• For men: BMR = 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) - (5.677 × age in years)
• For women: BMR = 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) - (4.330 × age in years)

Activity multipliers:

• Sedentary (little or no exercise): 1.2
• Light (exercise 1-3 days/week): 1.375
• Moderate (exercise 3-5 days/week): 1.55
• Very Active (exercise 6-7 days/week): 1.725
• Extra Active (very hard exercise, physical job): 1.9

3. Importance of TDEE Calculation

Details: Accurate TDEE estimation is crucial for post-bariatric patients to maintain appropriate calorie intake for weight management, support healing, and prevent nutritional deficiencies while ensuring adequate energy for daily activities.

4. Using the Calculator

Tips: Enter current weight in kg, height in cm, age in years, select gender and appropriate activity level. Use most recent measurements for accurate results.

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 calorie intake for weight maintenance while ensuring adequate nutrition.

Q2: How often should TDEE be recalculated?
A: TDEE should be recalculated every 4-6 weeks or after significant weight changes to adjust calorie intake accordingly.

Q3: Are there special considerations for post-bariatric patients?
A: Yes, bariatric patients may have altered metabolism and nutrient absorption, so TDEE should be used as a starting point and adjusted based on individual response.

Q4: Should protein intake be considered separately?
A: Yes, bariatric patients require higher protein intake (typically 60-80g/day) to preserve muscle mass and support healing, which should be prioritized within the total calorie budget.

Q5: When to consult a dietitian?
A: Always consult with a bariatric dietitian for personalized nutrition guidance, especially in the first year after surgery or if experiencing weight regain.
