They would actually probably die if they were suddenly given an abundance of food :( During the Siege of Leningrad in WW2 there was massive starvation in the city, hundreds of thousands of people died... when the siege was finally over and supplies were brought to the city there were people who died from just trying to eat because their bodies were so messed up due to starvation.  I heard heartbreaking interviews with survivors, one said that when her family and a few other families were evacuated they were given bread and some other simple food to eat but her grandmother stopped her from eating too much even though she wanted to eat more, the people who ate too much died.  Only saying this because I hate it when I see dumb people on Tumblr throw around terms like "starvation mode" and mean skipping a meal and then having an enormous meal to make up for it, real starvation mode messes up your whole body big time and it takes a long time to go back to just eating normally.
