The pattern follows a recognisable timeline.
The earliest changes are practical rather than visible - fewer takeaways, less time spent deciding what to cook, and a fridge with less waste in it. Those sound minor and they are the foundation everything else sits on.
With continued consistent use, the physical changes follow. Clothes fitting differently and a change on the scale arrive in proportion to how many weeks you actually cook the plan rather than how strictly you follow any single day.
Beyond a few months, the shift most worth having is from effort to habit - the plan stops being something you follow and becomes how you shop and cook. That transition is the clearest indicator that a plan has genuinely worked.
