What would [url=https://naruto.fandom.com/wiki/Calorie_Control]Calorie control[/url] fall under? It's not technically a bloodline limit or chakra affinity.

It could theoretically be copied if taught to someone else (or otherwise stolen), but that's largely mitigated by the fact that said justu is only viable if you're willing to go full [b][i]W I D E[/i][/b] like the Akimichi in order to have enough spare calories to actually make it useful and not potentially dangerous to yourself. It's got limited use, and the Akimichi basically have the market cornered on what it's used for. I'd also note on this topic (as I think I see what you're getting it specifically) that I used the word "usually" as far as being unable to be duplicated by outsiders. So, you'd still put Akimichi techniques in Bloodline, which is intended to include "Hiden" jutsu as well.

I'll edit the Bloodline section to be a little clearer on this front, I think. Thanks for asking that.
