Well，dieting can be effective, but the health costs are tremendous．Jules Hirsch，a research（研究） physician（医生）at Rockefeller University, did a study（研究） of eight fat people． They were given （被给）a liquid formula （流食配方）providing 600 calories a day1. After more than（超过） 10 weeks，the subjects(研究对象) lost 45kg on average（平均）．But after leaving the hospital，they all regained．The results were surprising：by metabolic measurement，fat people who lost large amounts of weight seemed like they were starving．They had psychiatric problems. They dreamed of food or breaking their diet2.They were anxious and depressed；some were suicidal．They hid food in their rooms．Researchers warn that it is possible that weight reduction doesn’t result in normal weight，but in an abnormal state resembling that of starved non-obese people． 答案相关句说“八个肥胖者被给予一种流食配方，每天提供600热卡”，因此D是答案。
