Just concluded a 90 day monitoring of my blood sugar. Sampled 3x a day:
- Morning (dawn) FBS (average: 90)
- 2 hours after lunch (average: 85)
- Bedtime (average: 81, 79 when I throw out a 'couple benders, but even a whole bottle of wine can't get my BS above 95.)
Total average was 85. Diet is solid "Bulletproof". 60% fat, 20% carb (~100g), 20% protein. No energy/health issues. Feel awesome. 10% bodyfat.
- My FBS spikes (>90) when I wake to "stress". Early meeting, catch a flight, went to bed late.
- My FBS spikes are also seemingly correlated to a lower bedtime BS. i.e. bedtime BS is 68, my FBS will be 90+. if my bedtime BS is 85, my FBS will be <90.
Obviously my FBS being the daily highpoint average is the work of the sleep-cycle waking horomones.
Over the next 90 days I aim to experiment with Carb backloading and sleep monitoring and am curious...
- Anyone corroborate similar results?
- Anyone play with sleep pattern, monitoring to adjust. Meditative waking.
- I aim to experiment with Carb backloading. Anyone have experience with what this will do to FBS?

You don't have Dawn phenomenon, your blood sugars are completely normal. Blood glucose spikes due to the Dawn phenomenon are perhaps an order of magnitude higher than what you're experiencing.
As to your question about higher morning blood glucose following lower bedtime blood glucose it has been proposed that this is due to counterregulatory hormones and called the Somogyi effect:
Note that the Somogyi effect is still quite controversial and (to my knowledge) does not have empirical support.
