Frequently Asked Questions
How many extra calories do I need during pregnancy?

How do I calculate my base calorie needs?
Base needs depend on your height, weight, age, and activity level. This calculator uses the Mifflin-St Jeor equation as a starting point.
Should I eat for two?
No. "Eating for two" is a myth. You need only moderate extra calories — roughly equivalent to a glass of milk and a small snack per day.
