I admire your self control, but remember that weight you starve off won't stay off unless you want to stay on a severely low-cal diet for the rest of your life! It might help jump start your weight loss, but it might also kill your metabolism.
Have you ever heard of what's called "calorie-shifting"? It just means eating a different number of calories every day, so your body doesn't know what to expect and your basal metabolic rate, therefore, can't settle and adjust to the fact that you're consistently eating less. It isn't the miracle cure that some websites make it out to be, but it's biologically sound, and probably better for your body than subsisting on 1200 calories a day, steadily. Particularly as it allows for variation in your diet, so you get different nutrients.
