Frequently Asked Questions
How many extra calories do I need during pregnancy?
According to ACOG guidelines: First trimester: no additional calories needed. Second trimester: approximately 340 extra calories per day. Third trimester: approximately 450 extra calories per day. The old saying of 'eating for two' is a myth.
What should I eat during pregnancy?
Focus on nutrient-dense foods: lean protein, whole grains, fruits and vegetables, dairy, and healthy fats. Key nutrients include folate (leafy greens, fortified grains), iron (lean meat, beans), calcium (dairy, fortified foods), DHA omega-3 (fatty fish), and fiber.
Should I eat more if I'm carrying twins?
Yes. For a twin pregnancy, you generally need about 600 additional calories per day beyond your baseline, totaling about 300 extra calories per baby. Protein needs are also higher at about 100-120g per day. Discuss specifics with your OB-GYN.
