Who said that the Brits were all vegetarians?

Add the somewhat more liberal political views (compared to the US anyway) that sometimes coincide with at least some of the reasons why some people decide to be vegetarian. But apparently low-carb may be taking off in the UK despite my misconceptions, albeit in perhaps a slightly less frenetic way:
