Calorie Needs During Pregnancy
How Many Calories Do You Need?
Calorie needs increase during pregnancy to support fetal growth and maternal health. The first trimester typically requires minimal extra calories, while the second and third trimesters need approximately 340-450 additional calories per day above pre-pregnancy needs.
Trimester Breakdown
First trimester (weeks 1-13): No extra calories needed for most women. Focus on nutrient quality rather than quantity. Second trimester (weeks 14-26): Add approximately 340 calories per day. Third trimester (weeks 27-40): Add approximately 450 calories per day. These are general guidelines from the Academy of Nutrition and Dietetics.
Activity Level Matters
Sedentary women need fewer base calories. Moderately active women should add the standard trimester increments. Very active women may need more but should consult their healthcare provider. Never restrict calories during pregnancy without medical supervision.
Quality Over Quantity
The extra calories should come from nutrient-dense foods: lean proteins, whole grains, fruits, vegetables, and healthy fats. Avoid empty calories from sugary drinks and processed foods. Focus on folic acid, iron, calcium, and DHA-rich foods.
