“…Weight loss and loss of body fat may play a role (Frisch & McArthur, 1973). Urinary and basal serum levels of LH and FSH increase with weight recovery in some but not in all AN patients (Beumont et al, 1976;Danowski et al, 1972;Hurd et al, 1977;Isaacs et al, 1980;Jeuniewic, Brown, Garfinkel, & Moldofsky, 1978;Palmer, Crisp, MacKinnon, Franklin, Bonnar, & Wheller, 1975;Russell, 1965Russell, , 1972Sherman et al, 1975;Wakeling & DeSouza, 1983).
