The only visible symptom of eating junk is having a bloated stomach. I won't die or anything, even tho I guess it will still lead me to having problems in life later on...
That said, today after I got my bloodwork done, I had planned to go to a bar and have a hot chocolate and some pastries, but, funnily enough, having my blood extracted made me temporarily lose all attraction to sugar, so I just went straight to the market and bought some pastured pork (liver, shoulder, ribs) to eat instead.
