The big question is which type of pre-diabetes. Do you have family history of adult-onset, non-insulin requiring diabetes? Are you overweight/inactive? If so, reduce weight, limit carbs, increase exercise, optimize other risk factors like smoking, cholesterol, blood pressure.
@AlphaCentauri No history of it and I will admit that I am inactive and overweight. Been trying to get to the gym more but my work schedule is not the best for that, which is sad because I work from home and the gym is like 5 blocks away from me.

Many insurances will cover consultations with a dietician before you're actually diabetic. It's good to find out what your approximate calorie intake is now and how much your regular foods contribute. Fats have the most calories per gram, alcohol less, and proteins/carbohydrates least. However, you'll often find carbs are not nearly as enjoyable as they ought to be for the grams/calories (they're bulky). So they're good places to start to reduce quantities.
@AlphaCentauri I was thinking about talking to a dietician because mine will cover it. And thank you for the information. This was wonderful stuff.
