Read our Obesity research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether sleeping in a special tent that lowers oxygen levels slightly—similar to being at high altitude—can help people with obesity lose weight. The study compares 8 weeks of overnight low-oxygen exposure to regular air exposure. Researchers believe that the body may burn more calories and feel less hungry when exposed to lower oxygen levels during sleep.
Current weight-loss methods like diet and exercise don't work for everyone, and obesity rates continue to rise. This treatment explores a new approach by mimicking what naturally happens when people live at high altitudes, where studies show weight loss occurs—but in a safer, more convenient way that you can do at home.

You would have a special tent and generator system set up in your home. For 8 weeks, you would sleep in this tent for 8 hours each night—it will either have slightly lower oxygen levels (similar to 8,500 feet elevation) or normal air, depending on which group you're randomly assigned to. Neither you nor the researchers will know which type you're in until the study ends. You'll need to avoid smoking, vaping, and certain supplements throughout the study, and come in for health measurements before and after the 8 weeks.
