Hello,
I have sold a diet plan on Clickbank since 2002, and have/had several weight loss/health related websites.
Over the years as I have learned more on the subject of weight loss and nutrition, I have always adjusted my Clickbank product accordingly and have a very low refund rate, because basically the plan works!
The plan I would propose for you would be based on my Clickbank weight loss plan, it is simple to understand, easy to follow, and the foods are available anywhere in the world.
I look forward to hearing from you.
