If your health care provider wants you to gain weight while you're pregnant, try these tips:
- Eat five to six small meals every day.
- Keep quick, easy snacks on hand, such as nuts, raisins, cheese and crackers, dried fruit, and ice cream or yogurt.
- Spread peanut butter on toast, crackers, apples, bananas, or celery. One tablespoon of creamy peanut butter gives you about 100 calories and 7 grams of protein.
- Add nonfat powdered milk to mashed potatoes, scrambled eggs, and hot cereal.
- Add extras to your meal, such as butter or margarine, cream cheese, gravy, sour cream, and cheese.
