Zig-zagging does 3 main things for me:
1) It seems to keep my metabolism higher. If I just do regular, steady dieting, it seems like my body adjusts and simply burns less instead of burning reserves.
2) I do like not having to stay strict and like being able to eat "bad" foods fairly often.
3) I don't feel weak and low energy on my diet because I am not in deficit for extended periods. This is both a physical and mental benefit.
I also don't like being too structured. My zig-zag is just a loose outline of a diet. On any given day, I really just go by feel.
