From an evolutionary stand point, bacon is the ideal food. Back in the day, before there were nutritionists and people ate to survive, cravings were responsible for encouraging the right balance of carbs to fats to proteins as well as the consumption of all necessary vitamins and minerals. Protein, which is found primarily in meat, proved to be one of the hardest nutrients for the ancient human being to find, since they would have to hunt animals in order to obtain it. Because of its importance to the human's diet and its difficulty to obtain, the reward system for proteins tends to be much stronger than that for any other nutrient. Carbs may result in an increased level of serotonin, but proteins release tyrosine into the blood stream which causes the release of massive amounts of dopamine, the "feel-good" neurotransmitter.
Bacon also has a great fat to protein ratio. Fats are another crucial nutrient because they are effectively concentrated, stored carbs which can be converted into ATP for energy on a cellular level. Containing nine Calories of energy per gram, one gram of fat is enough to sustain an average person in an inactive, waking state for ten minutes, though it may only last me a few seconds when I am riding my horse, Kaptain. This means that the average slice of bacon can sustain the average person for about one whole hour.
