Calorie needs during breastfeeding
Exclusive breastfeeding burns about 300-500 extra calories per day. Your calorie needs are therefore higher than before pregnancy. NEVER go below 1800 kcal/day while breastfeeding to avoid compromising milk production and your health.
A very moderate deficit
Limit your deficit to 300-400 kcal/day maximum. This allows slow weight loss (0.5-1 lb/week) but safe for you and your baby. Toxins stored in fat can be released during rapid weight loss and pass into breast milk.
Hydration is crucial
Milk production requires lots of water. Drink at least 2.5-3 liters (85-100 oz) per day. Dehydration can affect milk production and your energy. Keep a water bottle near you during feedings.
When to start?
Wait at least 6-8 weeks postpartum before creating a calorie deficit. Your body needs time to establish lactation and recover from delivery. Some experts recommend waiting until breastfeeding is well established (3 months).
Important
Never go below 1200 kcal/day (women) or 1500 kcal/day (men) without medical supervision. Too aggressive a deficit can be dangerous for your health and counterproductive for weight loss.
Complete Guide to Weight Loss While Breastfeeding
Losing pregnancy weight is a common goal, but breastfeeding imposes specific constraints. This guide accompanies you for safe weight loss that preserves your milk production.
Understanding Your Needs
Extra Calories
Exclusive breastfeeding requires about 500 extra kcal/day. A breastfeeding woman therefore needs:
- Sedentary: 2200-2400 kcal/day
- Active: 2500-2700 kcal/day
Absolute Minimum
Never go below 1800 kcal/day. Too low an intake can:
- Reduce milk production
- Affect milk quality
- Cause deficiencies for you and baby
- Release toxins stored in fat
The Safe Strategy
Maximum Deficit
- 300-400 kcal/day: No more
- Expected loss: 0.5-1 lb/week
- Priority: Milk production, not the scale
Timing
- 0-6 weeks: No deficit, establish lactation
- 6-12 weeks: Light deficit possible if breastfeeding well established
- 3 months+: Moderate deficit acceptable
Monitoring
- Watch milk production (baby’s wet diapers)
- Your energy shouldn’t drop
- Baby’s weight should progress normally
Optimal Nutrition During Breastfeeding
Protein
- 1.3-1.5g/kg body weight
- Essential for milk production
- Sources: meat, fish, eggs, legumes
Hydration
- Minimum 2.5-3 liters (85-100 oz)/day
- Increase if urine is dark
- Water, herbal teas, broths
Key Micronutrients
- Calcium: 1000-1300 mg/day
- Vitamin D: 600-800 IU/day
- Omega-3: Fatty fish 2x/week
- Iron: Monitor with your doctor
