Twenty four-hour passive heat and cold exposures did not modify energy intake and appetite but strongly modify food reward.

Effects of acute thermal exposures on appetite appear hypothetical in reason of very heterogeneous methodologies. The aim of this study was therefore to clearly define the effects of passive 24-h cold (16°C) and heat (32°C) exposures on appetitive responses compared with a thermoneutral condition (24°C). Twenty-three healthy, young and active male participants realised three sessions (from 13.

Evaluation of the efficacy of a light ration adapted to cold weather during a 20-day expedition in Greenland.

Introduction: Limiting body mass loss during military expeditions/training in the cold by providing rations containing easy-to-use, highly palatable, and familiar foods is feasible, but the bulk/weight is too high to be realistically used in a military context. We carried out an analysis of lighter rations adapted to cold weather (1,011 g, 15.7 MJ/3750 kcal) during a 20-day expedition in Greenland.
