Weight Loss

It's important to gain weight when you're pregnant. This extra weight helps your baby get enough nutrients to grow and develop. If you don't gain enough weight, your baby may potentially be born small, premature, or with other health problems. Don't worry if morning sickness makes you lose a little weight early in pregnancy, as long as you start gaining weight. Even if you're overweight, it can not be emphasized enough that this is not the right time to diet.

If you were a healthy weight when you got pregnant and you are carrying one child, you should gain 25 to 35 pounds. If you were underweight, you should gain about 28 to 40 pounds. If you are at a healthy weight and carrying twins, you should gain about 35 to 45 pounds. Discuss with your doctor what is your goal weight.

Call Doctor If:

  • You are losing weight during the 2nd and 3rd trimester (especially during the 2nd and 3rd trimester).
  • You are concerned about gaining too much weight. Your doctor can help you determine the right amount of weight gain for you.
  • You have an eating disorder that is keeping you from eating a healthy amount of food.

Step-by-Step Care:

  • Don't diet. Low-calorie diets during pregnancy can cause growth and mental deficiencies in babies. They are not recommended.
  • Drink high-calorie, nutrient-dense liquids, like protein shakes, when you're not hungry and not gaining weight.
  • Include healthy fats like nuts, avocados, canola and olive oil to your diet.
  • Drink milk and mix powdered milk into foods like hot cereals.
  • Eat small, frequent meals if you have trouble eating larger meals.
  • Spread peanut butter on toast, crackers, apples, and celery to add protein, fat, and calories.
  • Eat dried fruits, seeds, and nuts for snacks. Put them on top of cereal and yogurt.
