I started doing this over the summer more out of curiosity than anything. A friend mentioned only eating from 12-6 and initially my reaction was "how could you ever do that?" but somehow I ended up trying it too. I'll often eat a little something in the evening, but consistently not eating til 12 or 1 each day, and just drinking more water throughout the morning than I ever did before. While the hunger doesn't necessarily go away, I was surprised how quickly it became a non-factor (especially in the morning; somehow it's easier to hang on til lunch than the evening), and I actually appreciate being able to just live with hunger rather than feeling like I need to eat the moment I feel it. Down 18lb in 3+ months, probably haven't weighed this little since high school or early college.
