Hi Gino,
Your post linked below for those who missed it.
As you pointed out, our LORD Jesus ate and drank in His resurrected body. Your question as to whether we will continue to produce human waste in our resurrected bodies, is a good one! If we look at the messy, bloody, explosive methods Almighty God uses in His creation - it may be a little idealistic (and wishful thinking) that we may not be plagued by pesky things like needing the loo. Saying that, I don't recall Adam and Eve discussing lavatorial needs when they were still in the Garden of Eden - before the fall. Haha!
