Find your healthy weight gain range based on IOM guidelines and your pre-pregnancy BMI.
Frequently Asked Questions
It depends on your pre-pregnancy BMI. The IOM recommends: underweight (28-40 lbs), normal weight (25-35 lbs), overweight (15-25 lbs), and obese (11-20 lbs). These ranges support healthy fetal development while minimizing complications.
Yes. Most women gain very little in the first trimester (1-4 lbs total), then gain more steadily in the second and third trimesters. Weight gain can also fluctuate week to week due to water retention, digestion, and other factors.
Talk to your healthcare provider. Gaining too much increases risk of gestational diabetes, preeclampsia, and larger babies. Gaining too little can increase risk of premature birth and low birth weight. Your provider can help you adjust your nutrition plan.
For a 30-lb gain: baby (7.5 lbs), placenta (1.5 lbs), amniotic fluid (2 lbs), uterus growth (2 lbs), breast tissue (2 lbs), blood volume (4 lbs), body fluids (4 lbs), maternal fat stores (7 lbs). Most of this weight is lost within weeks of delivery.
Not exactly. In the first trimester, you don't need extra calories. In the second trimester, you need about 340 extra calories per day, and in the third, about 450 extra. Focus on nutrient-dense foods rather than simply eating more.
