1. What is Pregnancy EER?

Pregnancy EER (Estimated Energy Requirement) is the average dietary energy intake that is predicted to maintain energy balance in a healthy pregnant woman. It accounts for the increased energy needs during different stages of pregnancy.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Non-pregnant EER — The woman's estimated energy requirement before pregnancy
• Trimester Increment — Additional calories needed (0 in first, +340 in second, +452 in third trimester)

Explanation: The equation accounts for the increased metabolic demands of pregnancy which vary by trimester.

3. Importance of EER Calculation

Details: Accurate EER estimation is crucial for ensuring proper maternal nutrition, fetal growth, and preventing complications from under- or over-nutrition during pregnancy.

4. Using the Calculator

Tips: Enter your non-pregnant EER (can be calculated separately) and select your current trimester. The calculator will add the appropriate energy increment.

5. Frequently Asked Questions (FAQ)

Q1: Why are the increments different by trimester?
A: Energy needs increase progressively through pregnancy as fetal growth accelerates and maternal tissues expand.

Q2: What if I don't know my non-pregnant EER?
A: Non-pregnant EER can be estimated using standard equations based on age, weight, height, and physical activity level.

Q3: Are these values the same for all women?
A: These are averages. Individual needs may vary based on pre-pregnancy weight, activity level, and multiple pregnancies.

Q4: Should I eat exactly these amounts?
A: These are estimates. Work with a healthcare provider to adjust based on weight gain patterns and individual needs.

Q5: What about women with twins or multiples?
A: Additional increments are needed - consult a healthcare provider for personalized recommendations.
