So this was day zero. Not quite day one yet, because due to extreme stress, I wasn't able to finish anything that you see here and therefor I didn't manage to even come close to my caloric requirements to gain weight. I'm aiming to gain 35 pounds in 16 weeks. Not shown was my snack on my first break at work: it was a pot of Greißpudding (semolina pudding similar to cream rice) and the cup of licorice tea that I had with it. I also had a lemon tea at work which is also not shown. Tomorrow will be better.
So I give you: Day 0.
So that was my day zero. I intend to get started on my vitamins and up the calories tomorrow.
