What does the 80/20 rule mean?

The 80/20 rule is a flexible guideline, not a formal nutrition rule. It usually means choosing whole or minimally processed foods most of the time while leaving room for convenience foods, restaurant meals, or packaged options when they fit your routine. This often means no more than two highly processed food items each day. You can log your intake for 1-2 weeks to see your current balance, then gradually shift toward more whole foods. There’s no pressure to change everything at once.
