How thin is this boy? I have only eaten one meal a day for more than ten years.
Look at this boy in the photo, he is already very thin, and his arms are basically bare. It is not impossible to eat only one meal a day, but he must ensure the body's energy and nutritional needs. If he can't reach the balance, he will only get thinner and thinner. In this case, he is already a symptom of anorexia and needs treatment.
