Is eating meat or grain a more efficient way to get energy? Why?
Answers:
There is no practical energy available in protein. Sugar (glucose and fructose) has the most readily available energy of all foods. Second comes carbohydrates (grains, potatoes, etc) which our body converts to sugar. Carbs carry the same amount of calories as sugar per gram of weight, it just takes some energy and a bit longer for the body to utilize them. Third is fat which our bodies use for energy when stored sugar is less available. Lastly, (and you want to avoid this one)... protein. It CAN provide energy, BUT ONLY in an emergency... starvation. Your body literally consumes itself in this mode.
Since meat contains very little in the way of carbs or sugars and is mainly fat and protein as compared to grains which are high in carbs along with some fats, the answer is grains... by a very comfortable margin.
