I was recently diagnosed with T2, and in searching for information, he was one of the first sources that I found. I think he explains the relation of glucose, insulin, and carbs better than anyone else I've seen, and I love his dry sense of humor.
FWIW, using his information I decided not to use the Metformin I was prescribed and do low-carb. Not to brag, OK maybe a little, six days after diagnosis, and I was in pretty bad shape, my glucose levels have leveled out to below 180 on my GCM for 90% of the past 24 hours(I started out spiking in the 300 to 370 range) and I'm starting to get used to the low carb diet.
I'm in the US so I apologize if my numbers or not what you normally use in the UK. I'm still trying to figure out how the scales compare.
