Hi Darren (and welcome)
I, too, was diagnosed in January but not with such a high reading. I initially adopted the HFLC but took the HF a bit too far and my gallbladder complained quite a bit so I merely changed all my 'Low Fat' items (yogurts etc) to the full fat ones and I've managed to get my levels down. Through frequent testing I've found that carbs really spike me so I've given up bread, porridge, potatoes etc, and that seems to be working for me.
I'm sure some more experienced people will be along shortly to offer you advice.
