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 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.
- 01Total calories = 2,000 + 500 = 2,500 kcal
- 02Extra needed = 500 kcal for exclusive nursing
- 03Min safe (with 500 deficit) = max(2500 - 500, 1800) = 2,000 kcal
Frequently Asked Questions
How many extra calories do I need for breastfeeding?
Exclusive breastfeeding requires about 500 additional calories per day. Partial breastfeeding requires about 300 extra calories.
Can I lose weight while breastfeeding?
A moderate deficit of up to 500 calories below your nursing needs is generally safe. Do not go below 1,800 calories total to maintain milk supply.
What nutrients are most important while nursing?
Calcium, vitamin D, omega-3 fatty acids, iron, and adequate protein are especially important. Stay well hydrated as milk is mostly water.
