enough sweet potatoes and exercise, maybe a little extra fat isn't the end of the world (or maybe there are in fact significant differences in long term health outcomes that aren't being addressed), but unfortunately these nuances often get lost in translation and the average reader thinks oh goody, coconut oil ad libitum, and will surpass what the islanders were eating in total fat
consumption, without incorporating all of the other health promoting diet and lifestyle factors: activity, sweet potatoes and other low fat high
fiber foods, community, stress reduction, etc..
In order to increase your insulin sensitivity (decrease insulin resistance) you should: eat low — glycemic carbohydrates, make exercise part of your lifestyle, eat your omega 3 fatty acids, increase your
fiber intake, avoid trans fat, limit fructose
consumption, avoid fast food, go high in protein, flavor higher carb food with cinnamon, turmeric, or fenugreek, get
enough magnesium, avoid eating late at night, get
enough sleep, eat more vegetables, etc..
