Personal experience:
When I am dropping weight it is much easier for me to eat about 6 hours or later after I get up. If I have breakfast earlier I tend to overeat. So it works great, for me, to control my calorie intake. Bulking up would be harder due to needing to get in more calories but it is still do able. I also feel better when I eat later on rather than early. There is nothing special about it , it just helps me control my food intake.
As Andy stated it works for some but for others it is much harder to do. You also need to give it a chance and ease into it. Also I just call it eating to suit me not a special name like intermittent fasting.
