Understand how your body changes after childbirth

During pregnancy, women gain about 10–15 kg on average. About 5–6 kg comes off right after delivery, and the remainder needs to be lost gradually. However, breastfeeding, sleep deprivation, and hormonal changes make postpartum weight loss difficult. Excessive dieting can affect breastfeeding, so timing and methods are very important.

Optimal timing for postpartum diet

  • Up to 6 weeks postpartum: This is the puerperal period, when recovery is the top priority. Do not diet during this time.
  • 2 to 6 months postpartum: This is the optimal time for active weight management. Breastfeeding burns about 500 extra kcal per day.
  • After 6 months postpartum: Weight not lost by this point can become entrenched, so management should not be delayed.

Advantages of a Korean medicine postpartum diet

A Korean medicine postpartum diet manages weight while supporting recovery of qi and blood (氣血) in the mother. After childbirth, qi and blood are depleted, and forcing dietary restriction can weaken immunity and lead to postpartum complications such as sanhupung (postpartum wind syndrome).

  • Qi- and blood-tonifying (補氣補血) herbal medicine: Replenishes qi and blood while raising metabolism, leading to natural weight loss
  • Diuretic and decongestant (利水消腫) prescriptions: Resolve postpartum edema and help restore body shape quickly
  • Acupuncture: Effective for appetite control and metabolic stimulation, with no impact on breastfeeding

Postpartum weight management rules

Eat three regular meals per day, but reduce the proportion of carbohydrates and increase protein and vegetables. Start light walking after 6 weeks postpartum and gradually increase intensity. Rather than rushing, the ideal postpartum diet returns the body slowly to its pre-pregnancy weight over about 6 months.
