so what should i eat so that i won't die

I also purchased the book "Lore of Running" Lugging around and reading such a large book, will definitely give the upper body, and the brain, a good workout.

Put simply, carbo-loading cannot work simply because excess carbohydrates are not stored in a readily usable way.

The second problem lies in how the body uses its various options for fuel. Each of our body's cells contains lots of very small power plants called mitochondria. It is they that produce the energy we need from the food that we consume. Glucose is usually called the body's 'preferred fuel' because, if it is available, our bodies have been conditioned from birth to use it first. But it is not the best fuel. That distinction belongs to fats--or fatty acids, to give them their scientific name. Before the mitochondria can use either glucose or fatty acid as a fuel, it has to be transported into the mitochondria.

Fatty acids are transported into the mitochondria as completely intact molecules. Glucose, on the other hand, can be transported only after it has been broken down first into pyruvate by the process of glycolysis. This is then used anaerobically to produce energy with lactate as a by-product.

The by-products of the energy-production process when fatty acids are used are carbon dioxide and water, both of which are easily excreted. But when glucose is used, the lactic acid produced in the conversion process can build up in muscle cells and make them ache. It is this that is the cause of the aching muscles or pain involved in strenuous exercise--'the wall' as athletes call it. This 'wall' severely limits an athlete's performance.

So why would a person want to limit their performance by using carbohydrates for fuel?

Don’t take my word for it, how about the 1968 Olympic Marathon Champion, Mamo Wolde? It was 1968 at the Mexico City Olympic Games. The spectators at the marathon went wild as a relatively unknown Ethiopian, Mamo Wolde, won the marathon. Not only was the thirty-five-year-old runner the oldest man ever to win this prestigious event, he did it in record time. He also was a silver medalist in the 10,000 meters at the same Olympics.

Wolde grew up in an Ethiopian village. His life consisted of running after and hunting wild game on foot. His diet was high in animal meat and fat, with practically no carbohydrate. Subsequent tests showed that Wolde's body, under conditions of physical load, readily burned fat as its main energy source. Wolde had no concept of 'hitting the wall'. It never happened to him.

Are zombies high in fat or carbs?
