I did a lenient version of ND (about 900 to 1000 cals per day) necessarily for a long time as more cals makes it take longer. I lost only 11% of my weight. But today my hbac results are in - 40. FBG 5.3, down from 6.5 to 6.8. I consider myself reversed. Especially as for the last month because of a tummy problem I have actually been temporarily eating a high carb but low cal diet. Doc says he will repeat hbac annually.
