You've tracked calories. You've tracked activity. You've lost the weight, congrats! Now it's time to shift gears and keep it off for good.
Start by tracking your thoughts. Figure out what's really going to keep you motivated about maintaining your weight loss. Quickly find and correct any behavior changes before they lead to weight gain. It's simple. It's private. You get writing prompts like, "Why do you need to maintain your weight?" Then you write as little or as much as you want.
Your thoughts are motivating. You know what works for you. Create your paper trail and keep the pounds off.
