Arguably labour is intrinsically linked to the body providing the labour BUT selling does suggest handing over property on a more permanent basis. Would you be happier with SpaceNoodle saying they leased their body, given they committed to a set time period that their body could be used for their employer’s (lessor’s) purposes?
No it’s not, it’s about eating things that more easily signal to your body that you are full and learning to hear that signal, and in turn eating at a calorie deficit.
