How It Works

Calorie Needs While Breastfeeding

Breastfeeding requires additional energy to produce milk. The exact amount depends on how much milk is produced.

Additional Calories Needed

| Nursing Level | Extra kcal/day | |---|---| | Partial (supplementing with formula) | 300 | | Exclusive breastfeeding | 500 | | Exclusive + extra pumping | 650 |

Nursing mothers should generally not go below 1,800 calories per day to maintain milk supply and energy.

Worked Example

A woman with 2,000 baseline calories who is exclusively breastfeeding.

base_calories = 2000nursing_level = 500
  1. 01Total calories = 2,000 + 500 = 2,500 kcal
  2. 02Extra needed = 500 kcal for exclusive nursing
  3. 03Min safe (with 500 deficit) = max(2500 - 500, 1800) = 2,000 kcal
