It's really quite simple, as several scientists and others have noted long before me. In the 1930's, farmers learned how to fatten animals up - namely by feeding the corn, soy, etc. - in other words, foods high in unsaturated fatty acids that suppress the thyroid, slowing metabolism. With the current "essential fatty acid" fad, it's no surprise that we are now hearing about this obesity epidemic - it is basic biochemistry, actually. The studies are there, the farmers have known about this for decades, though they didn't necessarily know why, scientifically. Do you see a lot of fat Phillipinos, Sri Lankans, or Thai? No, because they use coconut oil, which is 92% saturated. I use coconut oil as a dietary staple. I'm 5'9" tall and thin as a rail. Everyone else in my family (they don't eat coconut oil) are obese, some dangerously so. Now you know - knowledge is truly power!
