Behavioral adaptation in diet maintains nutrient composition in an isolated, confined, and extreme environment in Antarctica
Despite environmental constraints and limited availability of fresh foods, participants maintained a rather stable nutrient distribution, suggesting broadly adequate diet quality. The observed weight loss therefore reflects insufficient intake rather than poor diet quality. These findings highlight the adaptability of dietary behavior under ICE conditions and underscore the importance of flexible yet well-structured provisioning strategies to ensure nutritional sufficiency and physiological resilience during long-duration stays in isolated and extreme environments.
