Carbohydrates
If we are terrified of carbs in our normal lives, the situation is reversed once you get pregnant. Half of an expecting mother's diet should consist of carbs. They are important for energy, which is needed throughout the day, and makes sure that protein won't burn away.  You don't have to eat pasta and sugar products all day. You can supplement them with whole grains, fruits and vegetables (most important) and yogurt. Carbs also contain fibers, which are absolutely essential for their role in keeping you regular and assure that you don't develop hemorrhoids.

Tip : Split your three meals into six or more

Eat a small meal every few hours. This will tie you over when ever you're hungry so you won't feel famished and eat a lot at once - you will still eat the same amount and your baby will get nutrients all day long.

Treats and Snacks

You don't have to avoid treats just because you feel guilty about your weight (which you shouldn't, ever). Candy bars, cookies and soda should not be your main diet by any means, but once in a while you may indulge yourself with ice cream or a cookie. If you are vigilant about staying healthy, eat fruit salad or frozen yogurt. You will surely get your sugar fix.
