Focus should not be so much on how much weight you are gaining

in pregnancy; but how well you are eating in pregnancy! It is recommended that women should aim for a weight gain related to their pre-pregnancy BMI: If BMI was above 26, you should aim for a weight gain of between 15 and 25lb (7 and 11.5kg).

If BMI was between 20 and 26, you should aim for a weight gain of 25 to 35lb (11.5 to 16kg).

If BMI was less than 20, you should aim for a weight gain of 28 to 40lb (12.5 to 18kg). Calculate your BMI - Body Mass Index The BMI is calculated and interpreted as follows:

BMI Below 19.8 is Underweight, BMI = 19.8 to 26 is Normal,

BMI = 26 to 29 is Overweight, BMI 29 and up is Obese. Calculate your BMI ¦ Avoirdupois/Imperial (U.S. / UK) » Metric converter
