INSIGHT

Identity, Not Willpower, Drives Habits

  • Repeated dieting failures usually stem from an identity mismatch, not lack of willpower or knowledge.
  • Cognitive dissonance triggers limbic resistance and raises cortisol, worsening metabolism and making change harder.
ANECDOTE

Vacation Ice Cream Example

ADVICE

Install A New Identity Statement
