Water balance and body weight: Studies in a tropical climate

Total body weight, water balance and energy balance were estimated in young adult men in a hot climate, over three 6-day periods. The aim was to determine the relative contributions to body weight changes of fluctuations in water and energy stores. In these subjects, the small observed body weight changes were due almost entirely to water balance changes. Water balance was regulated to within ± 1% of body weight from day-to-day. © 1975 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
