Bacon - Calories......... interesting.
https://commonsciencespace.com/bacon-calories/The average calorie content for these samples of cooked bacon, representing three different brands and not differing much from each other, was 144 Calories per 100 grams of raw bacon.
The average slice weighed 49 grams before cooking, and yielded cooked bacon with 71 Calories per slice.
The average slice weighed just 16 grams after cooking, for an average energy content of the bacon as eaten of 4.4 Calories per gram, if you want to do the calculation that way.
The cooked bacon contained about 41% of its calories in fat (present in the fat itself, and as part of the cracklings). The streaks of meat, and the meat present in the cracklings, contained the rest.
