Practical Applications for Exercise Professionals
For decades, some exercise gurus have been proclaiming that to lose more fat, enthusiasts should do their morning workout in a fasted state. This research clearly refutes that claim. Indeed, if a client seeks to burn more calories from a fat source, eating a light breakfast before the morning workout would be recommended. After the training session, this produces a sustained increase in metabolism (i.e., an increase in the chemical reactions in the body that liberate energy, measured by oxygen consumption) and a reduction in RER (causing the body to burn more fat as fuel).
Encourage clients to eat or drink something easily digestible at least 2030 minutes (or up to 1 hour) before the morning workout. Because glucose is the preferred energy source for most exercise, a pre-exercise morning snack should include foods that are high in carbohydrates and easy to digest. Such foods include fruits, breads, energy bars and energy drinks. It is best to choose carbohydrates with low glycemic indexes, as this will ensure greater fat utilization during and after the workout. Make sure clients also drink some water prior to their workouts, to ensure proper hydration.
