Days 3, 4 + 5
Day 3 I had to meet for lunch with someone AND go to dinner, so I definitely went over my cals, I think I had about 1200 split between the two meals.
Day 4 I had one snack on my lunchbreak and a piece of toast for dinner, in total I had 550 cals
Day 5 (today), I did a water-fast. Drank a lot of water and ate nothing, I plan to break my fast tomorrow sometime, so in total it will have lasted about 40 hours.
