The timing of maternal weight loss should be decided according to the woman’s body recovery. Women who are artificially fed can start after 3 months, and women who are breastfeeding should lose weight after they stop breastfeeding. All aspects of the body need a certain amount of time to recover after childbirth, and excessive weight loss may lead to a decrease in the body’s immunity and affect the body’s recovery. Usually, the body is in the recovery stage within 1 month after delivery, and it needs to eat rich nutrition and energy to promote body recovery. Women who choose to breastfeed after childbirth cannot lose weight by dieting, as excessive dieting will affect the secretion of breast milk and the physical development of the baby. Therefore, it is recommended that women choose the time to start dieting according to their own situation, which is usually recommended after 3 months. Breastfeeding women should wait until after they stop breastfeeding. Women in normal labor can get out of bed and move around briefly on the 2nd day after delivery. Aerobic exercise such as walking and jogging can be done 6 weeks after delivery. For women who had a cesarean section, aerobic and strength training should be increased slowly according to their condition and wound recovery.
