Understandable 
It’s firmly in the “impossible and extremely unhealthy for more than a few days” category for me, I don’t even care what it does as I never could or would do that. It belongs to the deepest parts of my room 101. (The whole room is merely “low-fat”, it’s scary enough for me.)
Tastes differ but yes, I probably would find it not tasty - even though all the items would be extremely tasty. I know zillion super tasty carbs - but I still can’t get satiated and satisfied without my high protein high fat… Never could so I always ate high protein high fat, all my life. It wasn’t pretty when I had high carb too… I am so, so, so very thankful it’s over and won’t go back to high-carb, it’s obvious since the beginning of my low-carb times.
Or for everyone at all if it’s not for a few days only (it’s bad for a few days too but a healthy body would handle it moderately well). I look at potatoes and human nutrition needs (it varies but there are a lots of common things) and I see them pretty far from each other.
And anyway, normal people would starve themselves like that, why not to eat nothing then (it seems way more enjoyable and better for me, surely not for all and I understand the charm of something being allowed, it helps mentally and potentially physically) or meat and eggs or something.
My hedonism and attitude always would end up with me quitting such strange diets even if I could choose to try them to begin with. I have so much better ideas. At one point that desperate last attempt idea was keto. How much things changed. Keto was extreme and restrictive to me back then.
I dislike the idea of having a deficient diet even for short term. Sounds wrong.
