University of Chicago Medical Center October 23, 1999 The Lancet.Chronic sleep loss can reduce the capacity of even young adults to perform basic metabolic functions, such as processing and storing carbohydrates or regulating hormone secretion Cutting back from the standard eight down to four hours of sleep each night produced striking changes in glucose tolerance and endocrine function--changes that resembled the effects of advanced age or the early stages of diabetes--after less than one week.Anorexia NervosaEating + emotional disorder Willful starvation< minimum body weightFear of weight gainExtreme dietingDiet pillsLaxativesIpecac Excessive exercise
