What this calculator does
A postpartum weight loss calculator estimates safe calorie deficit and timeline for losing pregnancy weight. Most women retain 10-15 lbs at 6 weeks postpartum. Safe loss is 0.5-1 lb/week, with considerations for breastfeeding and recovery.
How it works
Calculate TDEE with postpartum adjustments (breastfeeding adds ~300-500 cal/day needs). Apply modest deficit.
Formula
Breastfeeding TDEE = Regular TDEE + 300-500 cal. Safe deficit: 300-500 cal (not below 1,800 cal if breastfeeding).
Tips for using this calculator
- Wait 6-8 weeks before actively trying to lose weight
- Breastfeeding burns 300-500 extra calories daily
- Don't drop below 1,800 calories if breastfeeding
- Sleep deprivation affects weight loss—be patient
- Focus on nutrition quality over restriction
Frequently asked questions
Does breastfeeding help with weight loss?
Burns 300-500 extra calories daily, but hunger increases too. Effect varies individually.
When can I start exercising?
Light activity after 6 weeks (or when cleared by doctor). C-section requires longer recovery.
