If you eat less, there will be less excrement, and the intestinal peristalsis will be slow. Fine food can't stimulate intestinal peristalsis, which will make the feces stay in the intestine for a long time, and the intestinal mucosa will absorb the water in the feces, and the feces will become dry and difficult to discharge, resulting in constipation.
When constipation occurs during weight loss, you can eat some fruits that promote defecation, such as bananas, pitaya and watermelon. It is recommended to drink plenty of water every day, eat some crude fiber food and defecate on time.
