How do you keep cooked food warm for consumption later?

For this I will use my most-frequently used tips and tricks.  First you would build a fire that was sustainable, or use fireplaces that were built into the environment.  Then you would have a water source, which you could boil the water.  As the water boiled you would add the food and continue boiling it.

I don't need to cook the food. The food is already cooked. I need to keep it warm so I don't have to eat cold food later.

In that case you can put the food in containers that are insulated, which helps to retain the heat.  Also, putting the food in a dark place is good because it will keep heat.

OK, that changes the situation a lot.  Now you will have to store the food and the source of heat separately.  If there is no source of heat then this will be much more difficult.
