So did you reverse your pre-diabetes? It's hard to tell from this message. You mention that you feel better and that it's "working for me" but how can you know unless you get that blood work done? You may subjectively feel better but it may not be making a dent in your health.

Honestly, what most likely will reverse your prediabetes is that you are now working out more, eating less, and dropped 10 pounds. The IF was simply a compliance tactic to help you achieve that goal. Just something to keep in mind... it's okay if you eventually stop doing IF, what's more important is you maintain the healthy eating and active lifestyle.
