Dear Avi if you are looking for a UK based support organisation to help you with your health goals look no further than the Harcombe Diet.
http://www.theharcombedietclub.com/lifestyle/
Whilst not necessarily strictly keto (more managed carb) there is room for those who lean towards keto within the existing programme and many of my friends within the Harcombe Club are probably keto by default.
Have a look and see if you think it would suit you too!
