Managing your weight gain during pregnancyPrenatal care - managing your weight
Most women should gain somewhere between 25 and 35 pounds (11.5 to 16 kilograms) during pregnancy. Most will gain 2 to 4 pounds (1 to 2 kilograms) during the first trimester, and then 1 pound (0.5 kilogram) a week for the rest of the pregnancy. The amount of weight gain depends on your situation.
- Overweight women need to gain less (15 to 25 pounds or 7 to 11 kilograms or less, depending on their pre-pregnancy weight).
- Underweight women will need to gain more (28 to 40 pounds or 13 to 18 kilograms).
- You should gain more weight if you are having more than 1 baby. Women having twins need to gain 37 to 54 pounds (16.5 to 24.5 kilograms).
A balanced, nutrient-rich diet, along with exercise, is the basis for a healthy pregnancy. For most pregnant women, the right amount of calories is:
- 1,800 calories per day in the 1st trimester
- 2,200 calories per day in the 2nd trimester
- 2,400 calories per day in the 3rd trimester
