I do something similar, really seems to work. 3-4 days of zero carbs, 1 normal day then 2-3 days of high cals. Works like a charm. Google the Atkins Fat Fast- its 1,000 calories which may be too low for your height. Whole point is to eat 75-90% fat- I use a stick of butter which is 800 calories then add protein like fish. I put the butter on green vegetables. Hth.
