What are your stats Shortz? I tried IF for a solid week and felt flat, weak, and tired, but I have a feeling I'm significantly larger than you so it would explain how you can get your necessary cals in in a short amount of time.
I was really just avoiding this post, because I couldn't tell if it was an attack or not.
IF can have several different applications. The first and foremost though, is that of cutting or maintaining for people that have hunger issues and looking to control leptin and appetite. For about 80% of people, it's a great alternative. For people like you, who maintain very heavy weights, it might not be for you. Sure, eating the amount of food that someone like you has to eat would become a bit difficult to do in an 8 hour window. OTOH, if you were to decide to cut, and found that your hunger was out of control and you were having trouble, IF could be applied and work well.
I will admit, that I am starting to hit calories and macros that are becoming difficult to stay in that 8 hour window when I am trying to make gains, but when cutting, IF makes things so much smoother.
