Question
A 15-year-old boy with a height of 175 cm and weight of 52 kg is suffering from picky eating. Since the age of 15, he has had a decreased appetite and feels full after eating a small amount. He has been diagnosed with calcium deficiency, although he has supplemented calcium, he still grinds his teeth. He also had a duodenal bulb ulcer, which has been treated for two months but he still experiences belching during meals. He inquires whether this is unrelated to his weight and what the main influencing factors are for nutrient absorption and physical activity.
Answer
Weight gain or loss is not directly related to food intake; it mainly depends on nutrient absorption and daily physical activity. Both being underweight or overweight can cause inconvenience. It is recommended to focus on nutritional balance, maintain a reasonable diet, and establish regular living habits to promote health.
