Final answer:
Daniel is underweight because he is not eating much. This could be due to his preference for high-fat foods, difficulty with chewing and swallowing, and avoiding sugar-rich but less filling foods.
Step-by-step explanation:
Daniel is underweight because he is not eating much. There are several reasons why he is not eating. First, he likes scrambled eggs, which are high in fat. This may be causing him to restrict his overall food intake. Second, he is experiencing pain when chewing and swallowing, which can make eating difficult.
Third, he is avoiding foods like pudding and candy that are high in sugar but not very filling. These factors combined contribute to Daniel's underweight status.
