Another reason simulated high-altitude training may contribute to weight loss is that walking or jogging with nasal breathing allows the body to work with oxygen (aerobically), while incorporating breath holds every minute or so makes the body work without oxygen (anaerobically). During an anaerobic state the body is forced to burn calories from fat stores in order to produce energy. Incorporating both aerobic and anaerobic workouts into your training program will lead to increased calorie burn and weight loss.
