Tag: Hydration at altitude

A study on simulated Everest ascents found climbers had a significant involuntary weight loss of up to 5 kg, despite ample food. So, do you need to eat more at higher altitude? The answer is nuanced, involving altered metabolism, reduced appetite, and increased energy expenditure.

Research has consistently shown that prolonged exposure to high altitudes is associated with an imbalance between energy expenditure and energy intake, often resulting in weight loss. The physiological and environmental factors at play fundamentally alter your body's energy demands and consumption habits, making proper nutritional planning essential for anyone heading to elevation. This dynamic shift requires a strategic approach to fueling your body, from day hikers to multi-day mountaineers.
