Kelly Schmutte outlines three changes made to her environment to promote healthier habits: transforming flossing into a fun activity, creating a victory chain for daily ab exercises, and attempting to substitute snacking with walking. The floss art and victory chain proved effective due to increased motivation and accountability, while the snacking substitution did not succeed as the urge to snack persisted. Each initiative is analyzed through the Fogg Behavior Model to understand its effectiveness in prompting behavior change.
