Why? Most of the traditional lean societies in existence today are carbo-loaders. You're not going to find many traditional societies eating high fat diets because societies developed in equatorial regions where meat is lean and fruits and tubers are everywhere (and when you DO find a higher fat society, you'll find them in the tropics where they eat coconut, not fatty meat). There are few cold-weather traditional societies, so fatty game is pretty uncommon. Chances are, you descended from warm-weather carb-heavy societies. Starch is the very first thing digested for a human - that's why amylase is in our saliva. It emphases its importance in our development as a low-toxin, low-threat, reliable source of energy. There's a reason why we preferentially burn glucose over fat, and it's because we've been eating more of it longer. Also, it's very difficult to store glucose as fat. When you eat carbohydrate-filled meals, it's the dietary fat along with it you store as body fat, not the carbs. When you overeat steak and potatoes, it's the steak making you put on pounds in reality. It all comes down to caloric intake.
