Healthy weight gain during pregnancy is important for the health of both mother and baby. This calculator provides recommendations based on your pre-pregnancy BMI according to guidelines from health organizations.
During pregnancy, your body undergoes remarkable changes to support your growing baby. Weight gain is a natural and essential part of this journey. Most healthcare providers recommend gaining 1-4 pounds in the first trimester, followed by about 1 pound per week for the remainder of your pregnancy. This can typically be achieved by consuming an additional 300 calories daily - equivalent to a balanced snack like a sandwich with milk or a small meal combining protein and carbohydrates.
