Someone a year or so in the comments here posted up a link to a documentary that ran in England where they followed overeating studies. The subjects were people who couldn’t gain weight to save their lives. It was fascinating because some of these naturally thin people - who were forced to eat double their normal intake - actually gained all their weight as muscle even though they were forbidden to exercise. Some people had to drop out because they would throw up the extra food or just could not tolerate eating that much.
Anyway, reading the linked article now…thanks!
