Women eat a lot during lactation because they need to provide energy for the baby's growth and development at the same time. Generally speaking, protein, fat, sugar and more sugar water will be eaten during lactation to produce breast milk for the baby, so it is easy to get fat. After weaning, the body only needs to provide itself with calories and nutrition. Relatively speaking, I eat less food. Besides, you don't have to pay attention to your diet as before. You can eat more crude fiber foods such as vegetables, which is easy to lose weight. In addition, the level of prolactin in the human body has also decreased.
After weaning, if the baby does not eat breast milk, the nutrition in the body will accumulate, which may lead to weaning and getting fat. However, because the baby no longer eats breast milk, the body does not need to secrete breast milk, so the appetite will become smaller and smaller, eating less and less, and the weight will gradually drop.
