Maintenance Calories vs Current Weight

Postpartum Calorie Needs

This uses the Mifflin-St Jeor equation (female version) plus nursing calories.

Formula

BMR = 10 x Weight(kg) + 6.25 x Height(cm) - 5 x Age - 161

Maintenance = BMR x Activity Factor + Nursing Calories

A gentle deficit of 250 calories/day supports gradual weight loss of about 0.5 lbs per week. Never go below 1,800 kcal while breastfeeding.

Example Calculation

A 30-year-old, 155 lb, 65-inch tall postpartum woman, lightly active, exclusively breastfeeding.

  1. 01Weight = 70.3 kg, Height = 165.1 cm
  2. 02BMR = 10(70.3) + 6.25(165.1) - 5(30) - 161 = 1,384
  3. 03Maintenance = 1,384 x 1.3 + 500 = 2,299 kcal
  4. 04Gentle loss = 2,299 - 250 = 2,049 kcal
