What if psychologists ruled the world? In real life?

Brits are fatties and lie about it!

Brits are eating 50% more food than they admit to according to latest research from the Office of National Statistics (ONS).

Apparently we are exceeding the official health recommendations by the equivalent of one Big Mac a day.

Men are consuming 3.119 calories – not the 2,065 they own up to. And women are consuming 2,393 instead of the 1,570 they own up to.

The researchers used the National Diet & Nutrition Survey. Amazingly they found that a third of people in the survey actually claimed to be eating less than they would need to stay alive. People say that they are eating less than in the 1970s but it’s just not true as rising obesity levels illustrate.

This time the researchers used gold standard biological measurements of how energy is metabolised on a subset of the 4,500 in the survey. They then compared what this group said they ate and what the test results showed and extrapolated those finding across the whole sample.

Its’ clear you can’t trust self-report surveys when it comes to eating habits (or I suspect exercise habits as well).
