BMI < 18.5 Underweight: - Mean rate of weight gain in the 2nd and 3rd trimester = 0.5 kg/week; Recommended range of total weight gain = 12.5 - 18 kg. BMI 18.5 - 24.9 Normal weight: - Mean rate of weight gain in the 2nd and 3rd trimester = 0.4 kg/week; Recommended range of total weight gain = 11.5 - 16 kg. BMI 25.0 - 29.9 Overweight: - Mean rate of weight gain in the 2nd and 3rd trimester = 0.3 kg; Recommended range of total weight gain = 7 - 11.5 kg. BMI >= 30 Obese: - Mean rate of weight gain in the 2nd and 3rd trimester = 0.2 kg/week; Recommended range of total weight gain = 5 - 9kg.
