BTW, you’ll read below about body weight expressed in “stones.” That’s a term used in the UK and Ireland. One stone equals 14 pounds or 6.35 kilograms.

“The story of how Anthony and his younger brother Ian, 37, a documentary maker, intervened to bring their father back from the brink is told in a powerful new BBC film, called Fixing Dad.
The searingly honest documentary is a salutary tale for the 3.6 million people with Type 2 diabetes in the UK.
With his family’s help Geoff believes he has managed to ‘reverse’ the disease: he now weighs 13 stone and his blood sugar levels are so low he no longer needs diabetes medication.
His sons believe this may not have happened had they not stuck Geoff on an 800-calorie-a-day diet for eight weeks, an approach pioneered by Professor Roy Taylor of Newcastle University’s Diabetes Research Group.They also dramatically slashed his carbohydrate intake — by banning pasta and bread — after studies in the journals Nutrition & Metabolism and Diabetologia in 2008 and 2012 found this may be one of the best approaches to reset the release of insulin to safe levels again.”

Diabetic Mediterranean Diet 
Question – was it cutting the carbs or losing weight?
How do you explain the results with the MaPi high carb diet that reverses T2D?
Charles, I bet weight loss had a lot to do with it.

What if you cut the calories but not the carbs
My husband is T2. In February we went to a low carb diet without regard to the calorie count. He was on 3 metformin and 6 gabapentin tabs per day. His blood sugar immediately fell. He has dropped 2 metformin and cut his gabapentin In half. At the start his 14 day average blood sugar was 180 today it is 114. Last A1C was under 6. He has lost30+ lbs without watching calories. I’ve lost 27 lbs in the time. Never been hungry or felt deprived of anything.
Liz, thanks for sharing that inspirational story.
