The traditional Japanese diet contained a hefty amount of animal fat and protein. Way more than they eat now. It's not unlike the so-called Mediterranean Diet the fraudsters have been touting for years. I lived for a few years in Italy. You want to know what the real Mediterranean Diet consists of? Ham, chesse, sausage, salami, the fattiest meat you can think of. Italians treat their guests well, so they always cut off the fattiest parts of their meats for me always accompanied by the pronouncement that the fat is the most flavorful part.
The reason Japanese people don't get fat now even though they eat a high carb diet is because they don't eat a lot of fat with their carbs. If you spike your insulin with carbs, your body will store whatever fat you eat and use the carbs for its energy needs. So, fat with carbs is the most fattening. Carbs alone can make you fat but only if you eat beyond your energy needs. Fat alone without carbs is not at all fattening, because without insulin the body cannot store excess fat. They did experiments in animals in which they removed the pancreas, thus preventing all insulin release. Not only were the animals unable to put on fat no matter how much they ate, but they actually died from emaciation because they had no way to retain any amount of fat that they needed to stay alive.
