Effects of simulated high-altitude on appetite and energy intake in young women
Appetite and Energy Intake in Young Female Adults During and After Simulated High-Altitude
This study is testing if spending time in simulated high-altitude conditions affects how much young women want to eat and how much energy they take in.

What this trial studies
This clinical trial investigates how acute passive continuous hypoxemia, simulating high-altitude conditions, affects appetite and energy intake in healthy young female adults. Participants will undergo two randomized sessions of six hours each, experiencing either normoxia (sea-level) or hypoxia (simulated altitude of 5000 meters). The study aims to determine if hypoxic exposure reduces appetite and energy intake and whether these effects persist after the exposure ends. Participants will consume food from a curated list in ad libitum quantities during the sessions.
Who should consider this trial
Good fit: Ideal candidates are healthy young female adults who can speak English or French and provide informed consent.
Not a fit: Patients with chronic diseases, those on specific medications, or individuals who are pregnant or have irregular menstrual cycles may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide insights into how altitude affects appetite and energy intake, potentially informing dietary recommendations for individuals in high-altitude environments.
How similar studies have performed: While studies on hypoxia and appetite exist, this specific approach focusing on young female adults in a controlled setting is relatively novel.
