A disappointing story from New Zealand but one which the statistics would seem to bear out.

I do find this statistic interesting… “Forty six percent of New Zealand’s indigenous population, the Maori, are obese, as are 66% of Pacific Islanders resident in New Zealand.”

I have a theory that because Pacific Islanders were a people that spent a long time at sea moving from island to island, the food store they took with them for the journey was their body fat that was burned off during the journey. It’s the Pacific Islands that regularly top the charts of the most obese countries.

  
Maybe these islanders have developed genetics that favour fat storage (even more than you or I!) as a necessary means of survival in the past – that is now killing them today.
