Smell is like when you don't wash yourself for a week, quite unpleasant. It's gone on day 3, but on day 2 I am rather staying alone. Then from day 3 you might suffer from bad breath due to ketosis, regular oral hygiene is important when around other people.

Wow. I haven't not washed myself for a week but I imagine. Does showering more frequently help? I heard about the oral hygiene during the fast before. I am basically interested in doing a fast like this but am not sure if I could go to work if I smell unpleasantly but as you said I could probably start in such a way that the 2nd and 3rd days fall on a weekend. Thanks again!

I'd recommend starting on Friday, going through initial crisis on Friday/Saturday (caffeine/tea/sugar withdrawal), then from day 3-4 you should start feeling great (literally). Day 6 might be a bit weird so plan some lighter work around that time.
