James Clear’s bestselling book Atomic Habits popularized a key insight: lasting change comes not from goals, but from identity. Instead of saying, “I want to lose weight,” you say, “I am the kind of person who respects my body.” Instead of “I want to run,” it’s “I am a runner.”

Why does this work? Because behavior follows identity. When you see yourself as a healthy person, choosing water over soda isn’t a struggle — it’s simply what “someone like you” does.

Intermittent fasting supports identity-based change because it reframes eating patterns as part of who you are. With Fastry, you’re not “on a diet.” You’re someone who lives with mindful structure. That identity is sustainable, because it’s not about temporary restriction — it’s about how you see yourself long-term.

When you identify as a person who honors their fasting window, you don’t need constant external motivation. It becomes automatic — part of your lifestyle DNA.
