GP said it can take more than two years to get normal glucose levels.

I stopped weighing myself when I reached 264lb, on the way up, and am over 3 stone less than that now, and continue to lose inches even though my weight seems stable. I have less of an equator more a waistline these days and have had to remake or dispose of clothes due to my changing shape.

 

Three thinks that may speed up process (in addition to very low carb)

• Metformin, don't think of it as taking a drug for life, think of it as an option to get faster improvements. Most people don't get side effects for more then a few days provided they start with a low dose, take it with food, and slowly increase the dose.
  
• Resistance training to build muscle and hence reduce long term inslin resistance, I like the method in the "Body by Science" book.
• HIIT to remove gloygen from muscles and hence reduce inslin resistance over the next day or two..
• (Resistance training can be done as HIIT to get the most benefits)
