This is a comedic take on the 7 day vegan challenge. It's an animated short on this guy's experience of going vegan for 7 days.
He says that people claim that going vegan is supposed to solve all your problems. (If only it was that easy.) While it didn't solve his problems, he did stop craving as many meat and dairy products. He decided he couldn't go without the meat and cheese in the long run.
I haven't eaten meat or dairy for a long time. From that vantage point, it's easy to see how someone starting out for a short time like that is going to have a bad time of it. In the clip he showed, he ate a Boca burger with fake cheese on a white hamburger bun with tomatoes. He mentioned that he was lacking energy over the 7 days and was hungry. It's easy to see why. When he ate that white bun, it quickly turned to sugar. Boca burgers don't rival meat in terms of protein and fat. Fake cheese is just oil. He was probably hungry a couple hours after eating that and wondering why it wasn't as filling as a real burger.
It would be more interesting to see the review of someone who ate tasty, nutritious and filling vegan food.
I did enjoy his comedic take on it.
