It's amazing how this is never talked about. "They" tell you workout MORE to achieve better weight loss goals. More training, however, leads to an increased appetite & more eating. So, this formula doesn't make much sense. Your body will hit a point during your training, whether that's 90 minute to 2 hour workout sessions or whether it's the frequency, working out back-to-back days never taking time off for you body to recover, where it NEEDS more food. There is no question food is required for repair. This presents a dilemma when you use this model for losing weight. If your training kicks up a ravenous appetite, then it's time to adjust for some balance to you get results.
