When to start losing weight

Wait at least 6 to 8 weeks after delivery before starting a caloric deficit. Your body needs to recover and adapt to its new reality. For C-sections, a longer delay may be necessary. Always get approval from your doctor or midwife.

If you're breastfeeding

Breastfeeding increases your caloric needs by about 300-500 kcal per day. Never go below 1800 kcal/day to maintain adequate milk production and your energy. Breastfeeding naturally helps with weight loss, so be patient and listen to your body.

Very gradual progression

Postpartum is not the time for aggressive diets. Aim for a loss of 0.5 to 1 lb per week maximum. Your body did extraordinary work for 9 months - give it time to recover. The pregnancy pounds accumulated gradually, they will leave the same way.

Postpartum priorities

Your health, your baby's health, and your mental well-being come before weight loss. Sleep deprivation, hormonal upheaval, and adapting to life with a newborn are already significant challenges. Be kind to yourself.

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 Losing Weight After Pregnancy

Postpartum weight loss requires a patient and gentle approach. This guide helps you get back in shape safely.

The First 6-8 Weeks

Don’t Rush

During this period:

  • Let your body recover
  • Focus on your baby
  • Eat enough and balanced meals
  • Rest when possible
  • Avoid any caloric deficit

Natural Changes

You will naturally lose:

  • Baby weight, placenta, amniotic fluid
  • Excess fluid (about 7-11 lbs in the first weeks)
  • The uterus gradually returns to size

After 6-8 Weeks: Starting Carefully

If You’re Not Breastfeeding

  • Deficit of 300-500 kcal/day maximum
  • Minimum 1400 kcal/day
  • Target loss: 0.5-1 lb/week

If You’re Breastfeeding

  • Additional needs: +300-500 kcal/day for milk
  • Minimum 1800 kcal/day (non-negotiable)
  • Light deficit: no more than 400 kcal below your actual needs
  • Hydration is crucial

Postpartum Nutrition

Essential Nutrients

  • Protein: 1.4-1.6g/kg for recovery
  • Iron: Replenish stores after delivery
  • Calcium: 1000mg/day, especially if breastfeeding
  • Omega-3: For you and baby’s development
  • Fiber: For often disrupted digestion

Practical Meals

  • Prepare simple meals in advance
  • Accept help with shopping and cooking
  • Keep healthy snacks within reach
  • Hydrate regularly

Postpartum Physical Activity

Weeks 1-6

  • Light walking if you feel ready
  • Kegel exercises
  • Rest is priority

Weeks 6-12 (with medical approval)

  • More sustained walking
  • Gentle strengthening exercises
  • Postnatal yoga
  • Pelvic floor rehabilitation

After 3-4 Months

  • Gradual return to normal exercise
  • Light weight training
  • Moderate cardio
  • Watch for diastasis recti

Important Considerations

Mental Health

Baby blues and postpartum depression are common. If you feel overwhelmed, talk to a professional. Weight loss can wait - your mental well-being is the priority.

Sleep

Sleep deprivation increases hunger and makes weight loss more difficult. This is normal postpartum. Be patient with yourself.

Realistic Expectations

  • 9 months to gain the weight, 9 months minimum to lose it
  • Every body is different
  • Some women keep a few pounds, and that’s okay
