The Daily Mail says that the average weight of both males and females in Europe is UN 70.8kg in this article: http://www.dailymail.co.uk/sciencetech/article-2160934/Overweight-obese-threaten-world-food-security-study-warns.html giving no sources, but mentioning the WHO about other statistics in the previous paragraph.
When I try finding backing for these sources I run into a dead end: http://www.google.no/search?q=average+european+weight+70.8&oq=average+european+weight+70.8&sourceid=chrome&ie=UTF-8 All of the sources of this information seem to come from newspapers reporting the same story, and so I'm afraid this circular referencing.
Is there any backing for this fact, or any alternative statistic? Can we trust this source? Are there reliable sources for this statistic?
