"ease" is relative here. And if you really care about that debate you can find some social media challenge posts fantasizing about how you'd consume 10000+ calories for 1b dollars. I wouldn't drone much more on that point past calorie density being an undertalked about issue with these "calories in, calories out" crowd.
Main point: consuming 3000 excess calories a day roughly equates to an average person gaining 5 points a week, 20 pounds a month (which tracks with the documentary). That is extreme. But think of 1000 excess calories (2 pounds a week) and do it over a year. We know which one is worse, and we know which one is more common. And we know it doesn't just stop after a year.
I think there's merit in demonstrating an extreme experiment (especially in this day of social media) and using it to demonstrate what happens from less extreme, but longer term bad habits.
