Anything I could get in trouble with on this?

I am interested in starting a consulting service for people that want to achieve wellness from the inside out. I would so this by integrating my healthcare knowledge about disease processes, healthy living, supplements, custom designing exercise plans, and nutrition guidelines. It would be personal consultation. My question is, is there anything in the nurse practice act of TX that forbids the use of my R.N. title in an advertisement? I would not be claiming to treat any disease. In fact my focus would be primarily on prevention (It's about time we started doing that in this country!) for those who want to feel and look their best, from the inside out. Any advice would be appreciated.
