Plateaus are a normal byproduct of a functioning metabolism doing it's job of adapting to your new nutritional and training environment. Your metabolism will always seek to regain an equilibrium between energy taken in and energy expended—this process allows you to stay alive during a variety of nutritional circumstances. So yes... you will plateau. MetPro responds by adapting to your day-to-day weight and performance fluctuations, but will also alter your trajectory big picture (macro-cycles) to combat metabolic complacency--this is why you will experience occasional periods of increased intake even while you are on the weight loss progression. This is also why the "one diet forever" philosophy fails.
