First , during anorexia nervosa adolescent females lose more central body fat , while adult females more peripheral fat .
Second , partial weight restoration leads to greater fat mass deposition in the trunk region than other body regions in adolescent females .
Third , after short-term weight restoration , whether partial or complete , adults show a central adiposity phenotype with respect to healthy age-matched controls .
Fourth , central fat distribution is associated with increased insulin resistance , but does not adversely affect eating disorder psychopathology or cause psychological distress in female adults .
Fifth , the abnormal central fat distribution seems to normalize after long-term maintenance of complete weight restoration , indicating that preferential central distribution of body fat is a transitory phenomenon .
The aim of this paper was to conduct a systematic review of body fat distribution before and after partial and complete weight restoration in individuals with anorexia nervosa .
Changes in regional fat redistribution and the effects of estrogen during spontaneous weight gain in women with anorexia nervosa.
BACKGROUND Anorexia nervosa is a disease of severe acquired undernutrition with a high and increasing prevalence among young women in the United States . OBJECTIVE The objective was to investigate the effects of spontaneous outpatient weight recovery and estrogen administration on fat distribution in patients with anorexia nervosa . DESIGN Twenty-seven amenorrheic women aged 26.6 + /- 1.2 y with anorexia nervosa were identified through an outpatient study of bone loss and were r and omly assigned to receive or not receive estrogen without any dietary intervention other than calcium and multivitamin supplements .  Body composition was measured at baseline and at 6 and 9 mo and was compared with cross-sectional values obtained in 20 healthy , eumenorrheic , age-matched ( 25.4 + /- 0.5 y ) control subjects . RESULTS Twenty of the 27 patients with anorexia aged 27.0 + /- 1.3 y spontaneously gained weight ( 4.1 + /- 0.9 kg ) ; body mass index ( in kg/m(2 ) ) increased from 16.1 + /- 0.3 to 17.5 + /- 0.4 . Fat mass and lean mass accounted for 68 % and 32 % of the gain in total body mass , respectively . With spontaneous weight gain , there was a significant increase in the percentage of trunk fat from 32.4 + /- 1.3 % at baseline to 36.5 + /- 1.0 % at 9 mo ( P = 0.03 ) , which correlated with urinary free cortisol ( r = 0.66 , P = 0.003 ) . Estrogen treatment was not protective against the gain in trunk fat with spontaneous weight gain . CONCLUSIONS In women with anorexia nervosa , spontaneous weight gain is associated with a significant increase in trunk adiposity , and estrogen administration may not protect against the accumulation of central fat with weight gain
