Gain Weight Safely

The average pregnant woman will need about 300 healthy calories more a day than they did before they were pregnant. Ask your health care provider how much weight you should gain. A woman who was average weight before becoming pregnant should gain 25 to 35 pounds after becoming pregnant. A woman who was underweight should gain 28 to 40 pounds, and overweight women may only need to gain 15 to 25 pounds during their pregnancy.
If you are expecting twins, you should gain 35 to 45 pounds during pregnancy. Because twins are often born early, a higher weight is important for their health. So it is important to gain the right amount because your weight affects the babies weight.

- When eating fast food, order lower-fat items such as broiled chicken breast sandwich with tomato and lettuce (no sauce or mayonnaise), side salad with low-fat dressing, plain bagels, or a plain baked potato. Avoid foods such as French fries, mozzarella sticks, or breaded chicken patties.
- Avoid whole milk products. You need at least four servings of milk products every day. However, using skim, 1%, or 2% milk will greatly reduce the calories and fat you consume. Also, choose low-fat or fat-free cheese or yogurt.
- Limit sweet or sugary drinks, fruit punch, fruit drinks, soft drinks, iced tea, lemonade, or powdered drink mixes have a lot of empty calories. Drink water, club soda, or mineral water so you can skip extra calories. Do not add salt to any of your food when you are cooking. Salt causes you to retain water. Limit sweets and high-calorie snacks. Candies, cookies, donuts, cakes, honey, syrup, and potato chips have a lot of calories and little nutrition. Try not to eat these foods every day. Instead, you can try eating fresh fruit, low-fat yogurt, angel food cake with strawberries, or pretzels as lower-calorie snack and dessert choices.
- Use fats in moderation, such as cooking oils, margarine, butter, gravy sauces, mayonnaise, regular salad dressing, sauces, lard, sour cream, and cream cheese. Try lower-fat alternatives.
- Fry food in oil or butter will add calories and fat. Baking, broiling, boiling, and grilling are healthier preparation methods.
- Moderate exercise can help burn excess calories. Walking and swimming is usually safe for pregnant women. Talk with your doctor what exercise would be right for you, before you start.
