Two previously beefy Brits who converted to New Zealand's "atmosphere of fitness" have spoken out against two fellow immigrants who said their new home made them fat.
Elaine and Dave Forbes once had a penchant for pastry and pizza, but since moving in 2007 from England's northeast to Milford on Auckland's North Shore, they have shed 17kg and 29kg respectively.
They were spurred to speak up for their new land after reading the claim of British immigrants Mark Reyef and Tracey Blunn that the New Zealand diet contributed to their gaining 50kg within three years of their arrival in 2007.
The Rotorua couple said that after a fertility clinic turned them away because of Ms Blunn's excess weight, which can cause infertility, they each lost more than 30kg in a year.
New Zealand has the second-highest obesity rate, at 26.5 per cent - among developed countries that measure their populations - behind the United States, where the rate is 33.8 per cent. Britain was sixth, at 23 per cent, in 2009.
