I heard somewhere that he wrote in his journal later in life about loving pigeon sausages among other meat items. Probably heard it on QI

Edit: according to Wikipedia, Hitler was put on a vegetarian diet by his doctor right about the time he came to power as we know him today.

Goebbels made up his vegetarianism to make him seem more sympathetic. His chef wrote later about all the stuff they made for him, including meat dishes. I can post sources later if you really want but should be easy to find cuz its a commonly debunked thing now.
