Is energy consumption measurable in mass turned to energy and does energy weigh anything?

That makes sense to me.
In microgravity we observe another phenomena that supports the ToR and basic gravitational thermodynamics. That bodies in the vacuum of space attract, and in microgravity the bodies themselves would defeat the gravitational attraction of a distant larger body and attract each other, if the distance is right. I suspect the human 'dander' attaches itself to the walls and floors and ceilings of the ISS before it just floats around endlessly, but I suppose some time elapses before the dust settles so to speak. I do suppose a liquid spill on the ISS eventually attaches itself to the container walls also. So cleaning may not be as big of an issue as I first thought.
The earth gravity on the ISS is still the strongest force for dander, I suspect most land on the floor if the floor is closer to the earth, to them it really doesn't matter, once dander is attached to a wall earth gravity wouldn't move it from there, hence, microgravity.

Actually a small amount of mass will be lost. Because part of the sandwich will be turned into energy after it is eaten and then the person would burn the energy off.
