Energy split of Bacon, pre-sliced, reduced/low sodium, unprepared, as a share of total calories.

The USDA row is raw, pre-sliced bacon, so a 26 g slice reads about 106 kcal before it hits the pan; bacon loses well over half its weight as the fat renders out, and a cooked slice ends up closer to 45 kcal. The reduced-sodium label changes the salt, not the calories.
