Hello Mohamed Amr,
If you still insist, I would contact a few lawyers to get a ballpark figure. Like everyone else suggests, I have also been doing “health coaching” long before it was a “career”. No one else can possibly be you; so, be the best you possible and do not fret…not all business is good business anyway. Do your best, go with your instincts and knowledge to rest easy at bedtime.

I would contact a lawyer. An intellectual patent might be something worth securing.
A lawyer would help answer this best however.
Best of luck,
