Here's a possible future diet tip: Move to a mountaintop.
In a recent study, obese individuals who spent time at a mountain facility at high altitudes lost weight without going on a diet. And they kept the pounds off for at least four weeks once they returned to normal altitudes.
The researchers suspect part of the weight loss can be attributed to the thin air, which may have decreased participants' appetites and increased their metabolism, meaning they burned more calories sans a workout. While at high altitudes, the obese subjects also showed an increase in levels of leptin, a hormone that when present can make one feel full.
But don't head for the hills just yet — these findings are very preliminary and were only tested in a small sample of people. Further research is needed to confirm the weight-loss effect, and understand why it may occur.
