There is something wrong with the meaning of Chinese, and the last sentence "Is it beautiful again soon" doesn't feel right. And the sentence is not clear, so I changed it for you.

Li Hua is too fat, consult a doctor to lose weight. Tell him that eating more fruits and vegetables will soon make him beautiful.

Li Hua asked the doctor about losing weight, because he was too fat, and asked the doctor if he could become beautiful by eating more fruits and vegetables.

Li Hua is too fat to lose weight. He consulted the doctor and told him that eating more fruits and vegetables would soon make him beautiful. Li Hua is too fat. He wants to stay healthy. Consult a doctor and tell him to eat more fruits and vegetables, and he will soon become more beautiful.
