You have a fundamental lack of understanding as to what the Primal Blueprint actually is. You also have a fundamental lack of understanding of how the human metabolism works. There are no "fat burners" and "sugar burners." There is no such thing as a "fat burning beast." People with actual knowledge of health and nutrition rail against Mark for this. These are marketing terms because Mark is a businessman first. If you are not burning fat, you are dead. If you are not burning sugar, you are dead. The reason why the Primal Blueprint is successful for most is because when you eat less processed foods for more whole foods, you become better sated on fewer calories because 100g of carbohydrate from a potato will keep you a lot fuller than 100g of carbohydrate from wheat flour, and 500 calories from eggs is going to keep you fuller than 500 calories of Lean Cuisine, all while being more nutritious and providing wellness. The Primal Blueprint causes weight loss for one reason and one reason only - it makes it easier to maintain a caloric deficit. You just don't know you're calorie starving yourself because virtually no one's homeostasis will provide an appetite for a 50+lb weight surplus on a whole foods diet.

The reason why is because life evolved around the Equator where fruit and starch is everywhere and lean game meat is prevalent. We did not emigrate as a species to cold weather climates where fatty game is common until a few thousand years ago. You probably descended from people that ate more starch than anything else with relatively lean protein.
The end result - eat everything. If you don't consume glucose in your diet, your body will make it by breaking down your muscles, which is far less efficient. You're a sugar burner at all times as well. Choose your source - real food or muscles.
