I don’t know if taking energy from the body is a good idea. The laws of thermodynamics will require you to compensate. Also playing with very complex systems like a human body, neglecting what the side effects might be, is unwise on a good day.

Wouldn't it just burn more calories?

Isn't it just exercise? Unclear what the concern would be despite in general agreeing with you on human body being hard to change without side effects

Did you read even the first paragraph of the link? This is about using skin as a medium of power distribution to devices, not harvesting power from the human body. No hand-wringing required.

Possibly even worse then..

not to worry, we've got energy generation covered
