How many calories did the Jews get in concentration camps during the Holocaust?
It varied from camp to camp, and throughout the war. In the beginning the average seems to be around 1700 (though probably less as they based estimates on the average product of the time, and prisoners received products of a much lower quality meaning fewer nutrients), and towards the end of the war was possibly as low as 500 calories a day. This was on top of an extreme amount of labor as well.
