LOWS Trial Summary
This trial will test whether 8 weeks of calorie restriction, combined with exposure to either normobaric hypoxia or normoxia, leads to changes in body weight and composition in adults with obesity.
Who is the study for?
This trial is for adults with obesity (BMI between 30-39.9) in Tallahassee, Florida who don't smoke or use certain supplements and medications. They must have completed COVID-19 vaccination, live below ~7,000 feet altitude, and share a home with someone who can respond to safety alarms.Check my eligibility
What is being tested?
The study tests if sleeping in a low-oxygen tent at home for 8 hours nightly over 8 weeks affects weight loss during calorie restriction. Participants are randomly assigned to breathe either normal air (NN) or lower oxygen levels (NH), mimicking high altitude.See study design
What are the potential side effects?
Potential side effects may include discomfort from reduced oxygen such as headaches or shortness of breath. Long-term effects on body weight and energy balance will be monitored.

Placebo Group
Group I: Normobaric hypoxia (NH)Experimental Treatment1 Intervention
8 weeks of overnight exposure (8 hrs/night) to NH conditions (~15% oxygen; achieved with nitrogen dilution, equivalent to ~8500 feet elevation) using a commercially available tent and generator system (Hypoxico, Inc., New York, NY).
Group II: Normobaric normoxia (NN)Placebo Group1 Intervention
8 weeks of overnight exposure (8 hrs/night) to NN conditions (~21% oxygen; sea level) using a commercially available tent and generator system (Hypoxico, Inc., New York, NY).
