This guy is retarded.
It's genetics. Diet gets you to reveal your genetics. If you don't have the genetics for well defined lower abs, you're screwed.

Yes. Some people genetically do not have lower abs. There is just a hole there and if their bodyfat drops too low then it will start to absorb pets or children who get within several feet of it.

diet to get lean enough, genetics to determine whether your tendons will make a recess deep enough to define your 2 lower abs
