My body fat % is extremely low, but I can't remember the exact number. When I do those electric handheld fat % tests, they error out. I'm an archetypal tall and skinny nerd, basically.

The system works for me because I end up satisfying the craving on healthy stuff before I can get to the unhealthy a lot of the time. That said, everything I write about is based on personal experience and I just try to distill some of the general tips that anyone could use.
