I looked at his comment history and found 37 weeks ago that he says he only drank water and salt the first 30 days and added supplements the last 30 so I'm pretty sure he meant no calories. I also don't think that is a world record by any means. I found this site where someone they cite a 1972 NIH study of someone who fasted for 382 days but evidently I can't paste in this android client. Hunger strikes have definitely gone on for longer than 60 days. Water is essential but the body can subsist for a lot longer without food.
