Two things for you to consider:

1. Creating and maintaining routine is the best way you have to reach your fitness goals. This is probably more important than what you eat or how you exercise. Cut out bad habits one-by-one, add good practices slowly, and practice having good health.

2. Every single workout and every single diet has worked for someone - but not all diets and exercise routines will work for you. The problem is that all of our bodies really do respond differently and your job is to be the expert on your body and how it works. Don't get caught up in what everyone else is doing - focus on the results you're getting instead.
