Eating for two they say. At 15 weeks, my baby is about the size of an orange and weighs in at three ounces. I am quite sure he/she doesn’t require the same amount of calories that I do. Eating during pregnancy, especially in the first trimester, poses its own challenges with morning sickness and food aversions. Some of us are happy just to keep something down! I, fortunately, have never experienced the nausea and vomiting associated with morning sickness. A few bouts of mild nausea in the evening at around 6 weeks was the extent of it. I love researching and am paying greater attention to my nutrition with this pregnancy. My previous pregnancies were 15 and 18 years ago. My lifestyle is quite different now than it was back then. I enjoy nutrient dense foods and a variety of fruits and vegetables. Eating an extra 300 calories per day is the norm in the middle of pregnancy. A slightly lower number is needed during the first trimester and more than 300 may be needed during the final one, according to the American Congress of Obstetricians and Gynecologists. The primary purpose of the extra calories is to ensure the baby grows and develops properly.
Typical weight gain during pregnancy in 25-35 pounds. The amount of weight you should gain depends on your weight and BMI (body mass index) before pregnancy. You should gain:
- 25-35 pounds if you were a healthy weight before pregnancy, with a BMI of 18.5-24.9.
- 28-40 pounds if you were underweight before pregnancy with a BMI of less than 18.5.
- 15-25 pounds if you were overweight before pregnancy with a BMI of 25-29.9.
- 11-20 pounds if you were obese before pregnancy with a BMI of over 30.
