You might have different priorities than the OP when it comes to nutrition, or leisure activities - that's fine - substitute in your own priorities so we can talk about the process (Snacking Hierarchy) and its merits.
Whether step 2 is Vegetables or Nuts is immaterial. The point is that it's a progressive stepwise motion towards those tempting things that you're trying to avoid.
