First off they need to have an awareness for the need or want to have a reset. They need to identify what aspects of their life are "holding them back" or causing "health issues". I was told, you can't improve something unless you measure it. So, if they have not had one in a while, I advise people to go get a full physical and blood work. Request to be told the deficiencies, toxins or any dysfunction that is contributing to poor health.
After having a physical, they will have a baseline on where they are. Next they need to determine where they want to go, like on a map. Finally, like on a map they need to plan their route to get to where they want to be.
There are tons of resources and articles online to help one plan this route. Seek out a professional nutritionist, dietitian or trainer to help guide you on your path.
