Blood Glucose & Sleep First CGM Results!

Blood Glucose & Sleep First CGM Results!

Ok, I wasn’t expecting to email again so soon, but my first 24 hours with my continuous glucose monitor (CGM) were super interesting.

Here was my day yesterday:

  • Breakfast of 2 black coffees 7:30am
  • Work and protein smoothie and some cheese for lunch 1pm
  • Zestt Gut+ lozenges 4pm  
  • Gym from 5:30 - 6:45, a pretty hard cardio session.
  • Dinner, venison curry and rice 7:30pm.
  • Two homemade Blis Balls at 8:30pm
  • Bed and sleep by 10:30pm.
  • Awake and wired from 2:30-4:30am!

In the graph below (the actual results are the red line, target results is the green line), you will see my glucose levels never get out of control (over 10mmol/L), meaning my insulin system is functioning well, however, my nighttime glucose bump coincided with me being awake and wired - not ideal!

My nightly second glucose bump is driven by a mix of:

  1. Hormones (cortisol, growth hormone) → the dawn phenomenon.
  2. Delayed digestion of a bigger evening meal.
  3. A rebound if glucose dips after the first peak.

What I’m Aiming For Tonight:

  • Protein earlier in the day (I had scrambled eggs for brekky)
  • A smaller, earlier dinner and no Blis Balls ☹️, I will snack on some nuts if I am really peckish.
  • Finishing all food at least 3 hours before bed.
  • A short post-dinner walk to help muscles use up glucose.

The goal:

  • A gentler early glucose rise after eating
  • No big second bump at 3am
  • Flatter, steadier glucose through the night → deeper, uninterrupted sleep

It’s fun; I’m keeping things ‘normal’ at the moment, but next week, I will be experimenting with cheese scones and coke (the cola version) - keep watch and send me any reasonable requests 😅
