Quick answer
A pregnancy-specific energy estimate, not a weight-loss target. Uses published 2023 DRI equations rather than adding generic trimester calories to an ordinary adult formula.

Choose your details to see an educational estimate and its limitations. This tool cannot assess your pregnancy or replace your care team.
For the first trimester, the equation uses pre-pregnancy weight. From 14 weeks, it uses current weight, gestational weeks, activity category and energy deposition based on pre-pregnancy BMI. No additional trimester allowance is added. Estimates cannot measure your individual metabolism.
Method checked: 26 October 2026. No independent clinical review is claimed.
For adults aged 19–50 with a singleton pregnancy and no tailored medical nutrition needs. Activity classification is approximate. This tool does not prescribe a deficit, assess fetal growth or validate a restrictive diet.
