The medical profession want to do it but NICE is holding back, maybe as Jules say, until the results are in. My own experience with the medical profession is mixed, a diabetic nutritionist who put me on a high carb diet which led to 5kg weight gain and HBA1c of 11.5 when I had been 5.6. I managed to get down to 8.2 myself by cutting carbs down but still ate the usual culprits. Then, thankfully, I found this diet and I am back down to 6.7 with hope of a further reduction at the end of Nov test.
My own doctor is an absolute sweetheart and he asked me what I am doing wrong, I showed him the diet sheet, he said he couldn’t eat that much carb in a day and, as a Frenchman, loved his baguette. When, a year later, I told him I was on 800 cals he was gobsmacked but asked me what I ate and I showed him a 5 day menu plan. He said, okay, it is working, carry on. I had lost 4 kg since my previous visit as well as improving HBA1c. I had to see him last week to get a fit to exercise certificate and had lost another 2kg. So he is well happy.
