Spending time at high altitude leads to weight loss.
Independent of any other change in lifestyle, the unique conditions of high altitude appeared to increase metabolism, decrease appetite and lower blood pressure.
Published in Obesity, researchers said the low levels of oxygen present at high altitudes could be responsible for an observed increase in leptin, a hormone thought to suppress appetite.
The lasting weight reduction seen at high altitudes is primarily due to an increased metabolism and decreased food intake, though the reasons behind these changes remain unclear and may be a temporary effect of the body acclimatizing to new surroundings.
The clarification of mechanisms leading to weight loss at high altitudes might provide new tools for treating obesity in the future.
