I don't think it's really about the calories but the nutrition, which they're genetically predisposed to be deficient in for some reason or another. You can see them exhibiting behaviors classically related to missing out on important nutrients. They eat dirt (or in more recent years, corn starch, check out the niggers eating corn starch thread if you haven't yet it's a gold thread) because they're iron deficient and a lot of their common health problems (and probably some of their behavioral problems) stem from a chronic vitamin d deficiency because their skin is too dark to absorb sunlight in anything less than constant blistering sun. Imagine the smelliest neckbeard you can who nails blankets over his windows and lives in the basement, black people are kinda like that except touching grass doesn't do anything for them but make them hungry for dirt.
Edit: Decided to revisit the cornstarch thread because this post reminded me I haven't checked it in a while, it did not disappoint
