I went to his house and his mom said he only ate a Peach for dinner . When we work together he always has dizzy spells or says " head rush " both of which I know are caused by lack of eating . I feel really bad for him and I would love him to get better , but at the same time I almost like having him around for competition . He knows I have a slightly altered affliction with food but he does n't know how much .

Question: Why did the speaker 's friend suffer a head rush and feelings of faintness after eating only a peach ?
