An augmented food strategy leads to complete energy compensation during a 15‐day military training expedition in the cold
International audience Soldiers on military expeditions usually fail to compensate for the increase in energy expenditure, with potential deleterious consequences. We therefore analyzed the characteristics of energy compensation in 12 male soldiers, during a 15-day expedition in the cold, while alle...
