Hate me, but your goal is not at all realistic.
Have you sought out medical advice? A healthy rate of wight loss is half a pound to two pounds per week after the first two weeks of starting a new weight loss program (because you lose a ton of water weight etc in the first couple of weeks).
sixty pounds in ninety days is just plain crazy, and not at all healthy. Your body will start to reduce it's metabolic rate, making any further loss all that much harder, as you are starving it.
It takes an excess of 3,500 calories burned over those taken in over some period of time to lose a pound. It's impossible to do that every day for very long without some very unhealthy and potentially dangerous side effects.
