Uh yeah, no.

Bioluminescense relies on pigments and specific proteins involved to convert energy to a visible wavelength of light. This isn’t the same as the arbitrary calories we burn to maintain homeostasis or the resulting black body radiation.

That being said, gene therapy really has come a long way and bioluminescense is pretty well understood to the point of being an undergrad lab in intro bio, so really, there is nothing stopping you from GMO’ing yourself to have glowing pigments.

Also, if you making the claim we’ve got zebra stripes under some conditions, please explain those conditions.
