as of a few years aago, Scottish women were the lightest in the UK
//Weighing in at an average of 10st 3lb (64.8kg) and a height of 5ft4in (162.5cm), Scottish females are the lightest in the UK.
Their slimline figures may be explained by the fact that they eat more fruit than their counterparts in other regions and, perhaps somewhat surprisingly, eat the least fried food. However, their healthy eating is countered by the fact that they drink the most alcohol and eat more chocolate than women south of the border.
London can boast that its female population has the biggest bust, with an average bra size of 34C, compared with 34B in the North, Scotland, the Midlands and Wales.//
