It definitely did work for me. I've always exercised and eaten healthy food but haven't found any other way to stay at a comfortable weight all of the time.

Initially I didn't eat until noon for a few months. I went from 165 pounds to 135 and lost some strength. (I'm male and 5'6" tall). When I switched to eating at 10:30 or 11:00, I went back up to 145 and am about as strong as I was at 165. I've now stayed within about 4 pounds of 145 for a whole year, which is unprecedented for me. I'm mostly vegan but make a point of getting 20 grams of protein per meal and of eating soon after exercising. I don't have a cutoff time at night, I eat late if I'm hungry.
