Clinical Standards & Formula

The Institute of Medicine (IOM) and ACOG guidelines recommend weight gain targets categorized by pre-pregnancy BMI. During the 1st trimester, minimal gain (0.5–2 kg) is expected. During the 2nd and 3rd trimesters, steady weekly gains support placental perfusion and fetal organ growth.

Clinical Guidelines

Pre-Pregnancy BMI < 18.5 (Underweight) Target total gain: 12.5 – 18 kg (approx. 0.5 kg/week in 2nd/3rd trimesters). Nutrient-dense calorie enrichment advised.
Pre-Pregnancy BMI 18.5–24.9 (Normal) Target total gain: 11.5 – 16 kg (approx. 0.4 kg/week in 2nd/3rd trimesters). Balanced Mediterranean-style home food.
Pre-Pregnancy BMI 25.0–29.9 (Overweight) Target total gain: 7 – 11.5 kg (approx. 0.28 kg/week in 2nd/3rd trimesters). Regular walking and low glycemic index meals.
Pre-Pregnancy BMI ≥ 30 (Obese) Target total gain: 5 – 9 kg (approx. 0.2 kg/week in 2nd/3rd trimesters). Strict dietary monitoring to prevent gestational diabetes.
