Well the way I would see it done, is the nano tech attached to my arm has its own power supply, we shall call biomatter. This biomatter has enough power to break any matter down to its molecular state and store it, and reassemble it as needed. It does all the work to our energy needs through IV feeding and waste removal. It can even filter toxins put of the blood. Our bodies are filled with the nanobots that work to keep us in pristine shape.
Eating is done for a pure social or taste reasons, as there is no reason to eat anymore.
Any obaticle to this, has been overcome with 500 years of tech, energy and nano research.

This might be slightly unrealistic, but using your [insert future biotech-babble], if they remove the cap on how much you can fill your food bar, then instead of obtaining food filling your inventory with food and then eating it each time you are hungry, you could just eat it when you obtain it and have the stomach serve as the food inventory. This way you get the immersion of having to actually eat without the annoyance of making it any more of a chore then putting it in your inventory in the first place.

My thought was that it will discourage pvping to some degree. but not in a negative way. You would have to plan the logistics of long warfare for a large force or plan and build an agricultural ship that can supply the fleet. Which just adds another target during wars. gotta take out the agriculture ship as well as the one with the RN on it. But I see this as just another reason that people wont aimlessly start wars and such which i think people who are not interested in the pvp side may actually like.
 
My thought on the mechanics on your surroundings is that the suit would house a kind of camel back with water and it depletes at a certain rate at idle and while doing different types of actives it would deplete at a faster rates. The food part im not sure how that would be taken care of. i would assume that you would have to store food in your pack unless its processed into a paste that you drink through a straw in your suit. which honestly doesn't sound great lol
