I've seen a handful people close to me go from 100lb+ overweight to a more comfortable 10 to 20 (or 50). And I think what GP described is a fundamental change to the relationship with food: You're (consciously at first) changing the definition of what needs to be consumed vs what is being consumed without need. They've all from what I've observed gone through this change.

They said that when you're really big, the first 10 lbs is the easiest to lose, and can come from taking stairs and changing snack habits. It's the last 10 lbs that requires the diligent workouts and very strict diets.
