So my sleep experiment was very successful — nearly no change in my diet or my physical activity, yet, ditching the alarm clock, yielded 1 inch off my waist, 3 pounds lighter, and a body fat reduction of 1.35%, all in just 1 week. This finally allowed me to break through my 2 week plateau. I was surprised since my carb intake on average has been a bit high, around 247g a day, with a few meals containing bread, pasta, and a couple of nights of very rich desserts. I will definitely no longer be using the alarm clock now, only as a last minute wake up call for really long sleep, which should be rare. I say rare since I changed my schedule to assume 10.5 hours of sleep a night, 7 days a week, so I can awaken without alarm and be fully rested every 24 hour period. When I only need 9 hours, my average so far, I get time in the morning before work to read, study, or work on personally meaningful projects — it feels nice to not ever feel rushed in the morning, or groggy. On my really demanding / exhausting workout days, I easily use the full 10-10.5 hours of sleep.
