I have found that people tend to have trouble staying with lifestyle changes if they are simply making changes because they are told to. Feeling forced to do something (even if to save your life) or blind obedience to a set of rules often brings about rebellion.
It is important that we truly understand what we are being called to change and why. So where do you begin?
1. Learn everything you can about why you are being called to make this change. Do your research, then sit with the information for awhile. Let it become part of you.
2. Look at the consequences of not making changes.
3. Realize that you do have a choice. Are you willing to live with the consequences of not changing?
4. Embrace the change. Welcome it into your life. Make if a part of who you are.
Once you can reach a point of choosing health and life and not feeling forced to do something against your will, life will become much easier. Remember you always have a choice.
