Oblomov, yep I'm sure about the 50% energy intake from carbs because I checked the guidelines after reading it in an article. I thought it couldn't be true, but it is.
This article is about middle class kids, but it's one of a glut of articles identifying rapidly growing levels of obesity in every age group and social class so it's a pretty irrelevant observation, imo.
Most people in the UK will be eating cereal or bread for breakfast, a sandwich or jacket potato for lunch, then a pasta/rice based meal or pizza for dinner. In fact that might be viewed as being 'healthy'. Not rocket science that 50-60% of the population has weight issues.
