About How Many Calories Should A Pregnant woman consume daily?

It depends on your ideal weight, your activity level, and whether you are overweight, underweight, or normal weight. If you are underweight, you should gain 28-40 lbs; if you are normal weight, you should gain 25-35 lbs; and if you are overweight, you should gain 15-25 lbs. If you are normal weight, this equates to about 200-300 extra calories per day (not much!). You don't need to gain weight in the first trimester. For example, someone who is 5'4" and weighs 115 lbs. and who walks an hour per day but has a sedentary job should probably consume 1800 calories per day. If this person becomes pregnant, starting in the second trimester (week 14), she should consume 200-300 more calories - 2000 to 2100 calories per day.
