Frequently Asked Questions

How many extra calories do I need while breastfeeding?

Exclusively breastfeeding mothers typically need an additional 450-500 calories per day. Partial breastfeeding requires about 300-350 extra calories. Your body burns these calories producing breast milk.

Can I diet while breastfeeding?

You can lose weight gradually while breastfeeding, but avoid crash diets. Aim for no more than 1-1.5 pounds per week. Eating too few calories can reduce milk supply and leave you fatigued.

How much weight should I gain during pregnancy?

Recommended gain depends on pre-pregnancy BMI. Underweight: 28-40 lbs. Normal weight: 25-35 lbs. Overweight: 15-25 lbs. Obese: 11-20 lbs. Multiple pregnancies require more gain. Consult your doctor.

When do you gain the most weight in pregnancy?

Weight gain is minimal in the first trimester (1-5 lbs total). Gain accelerates in the second and third trimesters, averaging about 1 pound per week for normal-weight women.
