  It usually takes about 4 to 6 hours for a full stomach to digest the food. However, this varies from person to person, and if vomitting occurs, much less time. It takes â¦ from 12 to 24 hours for the food to completely leave the digestive/excremetory systems.ome meals can take 10 minutes start to finish  while others can take 30 minutes or o â¦ ver 3 or 4 hours. It also  depends on what you use to cook it.
Usually takes about 6 or so hours for food to move from your stomach to your duodenum. After that, it is totally dependent upon your metabolism, and what and how much you ate (I think nachos move faster....). Still, I have a link from a Mayo clinic study from the 80's that measured the average in healthy adults, and arrived at 53 hours average from eating to ...., and that probably was a high estimate. Seems very slow to me, based on my experience, but looking around, 40-50 hours seems to be a general estimate.
