fat oxidation rates and energy expenditure in both groups in the evening were higher than morning; there were no significant differences in MFO between obese and normal groups. Furthermore, the fat oxidation rate in low intensity exercise (<60% VO2max) was similar in obese and normal weight groups, but in high exercise intensities, in normal weight men were significantly higher than obese men.Obviously, these results have practical implications in terms of exercise time and intensity which also depend on the training status / body composition of the individual. For "optimal" fat loss while training in a "fasted" (or at least not a postprandial state)...
- normal weight men optimally train in the PM at an exercise intensity >60% VO2max
- obese men optimally train in the PM at an exercise intensity of approximately 60% of their VO2Max
[...] with additional load, high vibration frequency and/or amplitude [...] cannot match the demands of conventional aerobic exercise. Therefore, caution is required when VbX programmes are solely used for the purpose of reducing body fat without considering dietary and aerobic conditioning guidelines.

On a side note: Isn't it interesting that the results of this study suggest that higher intensities become more and more effective, the leaner / fitter you get? Well, guess why most studies on obese people showed benefits of light intensity steady state cardio, while more recent studies on fit people or even athletes suggest that high intensity interval training (HIIT) is far superior to "recompose" your body.
