6. Change your mindset

It's not enough to eat healthy foods and exercise for just a few weeks or months. To keep off extra weight, you should make these healthy changes a way of life. Lifestyle changes start with taking an honest look at your eating patterns and daily routine.

Think about negative habits or other challenges that have kept you from losing weight in the past. Then plan for how you'll deal with them going forward.

You'll likely have some setbacks on your weight-loss journey. But don't give up after a setback. Simply start fresh the next day. Remember that you're planning to change your life. It won't happen all at once. Stick to your healthy lifestyle. The results will be well worth it.
