All decision-making is a values-clarifying exercise.
If you do extreme exercise to lose weight, you'll usually soon stop because you get injured or because it's simply too rigorous to do for a lifetime.
You're far more likely to lose the weight and keep it off if you lose slowly, perhaps ½ to 1 pound a week, exercise moderately, and find that replacement for comfort, connection, and control. That's a doable long-term plan.
