    • One week observation of my sympathetic arousal
    • and my eating behavior
    Presentation at the Quantified Self Europe Conference Amsterdam, 26.11-27.11.2011
  • 2. Yorgos Papastefanou Ludwigshafen/Germany
    • What governs my eating behavior?
    • What is the relationship between my emotional reactions and my eating behavior?
    • I know from literature, that stress influences eating behavior. Stress physiological mechanisms lead to desire for comfortable food (fat, sweet)
    • I am doing my personal program for losing weight (eating less and mainly non-cooked vegs and fruits, 1 hour/day crosstrainer)
  • 3. How did I do it? sensor wristband push button keypad smartphone camera
    • Skin conductivity
    • Skin temperature
    • Opto-electric sensor
    • tri-axial acceleration
    • Ambient temperature
    • 12 buttons keypad
    • 50 Hz
  • 4. What I ate/drank Wednesday 17.11.2011 Friday 18.11.2011 Saturday 19.11.2011 Sunday 20.11.2011 Monday 21.11.2011
  • 5. What did I learn? retrospective introspection
    • In the beginning it bothered me. It precluded doing homework. After one day I got used to the wristband (but did not more homework).
    • It was kind of satisfying to mark my hungry feelings.
    • I liked to measure myself (esp. pushing the hunger marker). I missed it after stopping. This experience pointed me to social psychology of objective self-awareness.
  • 6. What did I learn? Quantitative analysis
  • 7. That’s it for now.
