You only need about 300 extra calories a day while you are pregnant, less in the first few months and slightly more during the last months of pregnancy and depending on your activity level. Avoid empty calories from junk foods and sodas. Eat healthy snacks like yogurt, low-fat cheese, and fresh fruits. Do NOT use this time to begin a weight loss diet. If you have concerns about your weight, talk to your doctor.
Food cravings are normal.
It's OK to eat the foods you crave, but just as when you aren't pregnant, do it in moderation. If you are gaining too much weight, cut down the foods you may crave that are high in fat, sugar, and salt. Some women crave non-food items such as starch, dirt, or clay when they are pregnant. If it isn't food, don't eat it. Restaurant meals can be high in fat and lacking in nutrition for you and your baby.
