Abs are over rated, mostly by kids. They help you stand up straight, that is about it. No one has ever said, to me any way, "Man, your posture is great, you must have fantastic abs."
At your age, height and weight, how much you eat should be the least of your concerns. Rather than focusing on the obsessive concern about how you might look of you were actually able to eat 10,000 calories a day, focus on getting stronger. EAT WELL, SLEEP WELL AND TRAIN WELL and you WILL grow. As I stated in one of your other threads, you are still growing, should have a metabolism the rest of us would die for and have not even reached your natural growth peak. Stop worrying about all these little things that don't really matter. At your size, you have minimal body fat and should have some semblance of abs. Enjoy them if they mean that much but realize that if you want to get stronger, heavier and more muscular, you may have to sacrifice them for a while.
