Dieting with willpower is like holding a beach ball underwater.

You can do it. For a while. Arms burning. Face clenched. Focused on nothing else.

But eventually your arms get tired. And that ball doesn't just float up gently. It explodes out of the water.

That's the binge. That's the rebound. That's the 20 pounds you gained back plus 10 more.

You were never weak. You were just holding something down that was always going to come back up.
