What advice would you give to an individual who is pre-diabetic?

Learn and understand how diet impacts blood glucose and weight, and how being overweight increases the likelihood of becoming full diabetic. Learn the foods that can spike blood glucose levels and the foods to be cautious of, such as anything "white" like bread and rice. Also, be very cautious of highly processed foods (no matter how the marketing says they are healthy) and simple carbs.

Well, I would recommend starting reading about diabetes and what is good and bad to get in your body. 

I think Education about your condition is the most important part in order to know how to take care and live a healthy lifestyle. This article for example is one I found this week that talks about the fruits we can eat, that's just one example but you can find many research cases and blogs that give you some great information.
