You can lose weight by dieting after childbirth, but dieting can only be done after lactation, because lactating mothers need a lot of nutrition to feed their babies. Dieting to lose weight will be bad for both the baby and the mother, which will lead to insufficient milk for the mother. Mom can lose weight by adjusting her diet after lactation, but she must have a balanced diet, less salt and oil, no fried food, no nutritious food, more protein and more vegetables. In addition to dieting, if you add moderate exercise to make the weight loss effect better, mothers can walk more and do some simple aerobic exercise, but not too intense.
