Limit The Fat

Since this is my first pregnancy I feel like I gained a lot of weight and have a lot of stretchmarks. To me I know that I gained more weight than I expected because when I hit my sixth month I started to eat more then I did when I was 1-5 months. During those months I couldn't stand the smell of food I hated waking up to cooked food because it bothered me so much. But after my sixth month I started to eat up everything, like I started to eat fried chicken, fish and all the meat I would smell. I didn't worry about what I ate, just as long as I wasn't throwing up anything and feeding my baby. The next 4-5 weeks I went back to my mid-wife to check up on how the baby was doing and how I was doing, she had told me that baby's heart beat is normal and that I gained about 20 pounds during the middle of my sixth month I was so shocked and didn't know if I'm ever going to loose any of it after the baby is born. I'm still worried about having all the weight on me after my son is delivered. At this point on I should only worry about eating fresh fruit, peanuts, eggs, yogurt, more milk and protein so that way I would stay fit and not gain all the other extra weight I shouldn't have.
