I believe to fix problems, we must find the underlying root cause, then, based on the findings, make the necessary changes to solve the problem. I believe that our health problems, started back in the 1800s when Samoa was colonised by the Germans, then Britain and finally passed on to New Zealand. Prior to colonisation we lived off the land and sea farming chickens, pigeons, pigs, goats, ducks, taro, banana, yams, and ta’amu to name a few. Fishing was massive as well. We were literally living on pure organic food and people were strong and fit from working hard on their daily routines.
Factors to consider:
* Poor diet and lack of physical activity leads to weight gain
* History shows that our people were not obese
* Good diet and physical activity leads to good health 
"Samoans weren't obese 200 years ago,". "The gene hasn't changed that rapidly — it's the nutritional environment that changed that rapidly." Pr Steven McGarvey, PhD, of Brown University
