That’s much easier. If you weigh 100kg (220lb) it’s W/(100 + W) = 0.8, and solving for W gives 400.
If you eat 400 kg of wine powder then 80% of your mass will be wine.
This will kill you, and it doesn’t actually matter what powder you choose to eat.

You are saying that you would have to eat four times your body weight of wine powder to turn your blood into wine. That doesn’t make sense.

It kinda does its just not what you expected (and not what the question meant). In a 500kg mixture of you (100kg) and wine (400kg), exactly 80% of that mixture is wine and 20% is you.
To answer the actually question you’d need to know how much extract you need to turn 1L of blood into 1L of wine and I’m to lazy for that math.
