Lower Readings At Weekends

Some interesting analysis. After a particularly spiky day, I was prompted to look back over my blood test results over the last couple of months and I've noticed a distinct trend. What prompted me to look was continually getting high readings in the middle of the day, often higher before my lunch than after it. I test usually 6 times a day, before and 2 hours after every meal. I have over 250 results since I started testing, so enough for a statistically significant sample.
I noticed when I looked over the results that this trend of higher lunchtime readings didn't seem to be happening at weekends.
In fact at weekends my results are 4% lower than on weekdays, and 9% lower for those weekend readings in the middle of the day. My readings are fairly consistent either side of breakfast, and fairly consistent either side of dinner (a bit lower at the weekends maybe due to a bit of wine!).
The weekday middle of the day discrepancy though is worthy of investigation because it is quite a consistently big margin of difference. My food diet isn't any different and in fact I am more likely to have some porridge at the weekend for breakfast (although it doesn't spike me). My diet is mainly LCHF and I rarely see big post meal spikes. I have two main suspects for the difference - which I intend to put to the test in succession,
Firstly is the obvious difference that I work during the week, so am moving around more, under more pressure, more stress. I'll see if this changes when I take some time off in a couple of weeks.
However, I think the more likely candidate may be coffee. I think I drink more coffee and stronger coffee in the week than at the weekends, and I think this may be spiking my readings.
Anyway I will report back to see if a decaff-detox helps lower my scores on weekdays but I thought I would share in case anyone else has any observations they think I might be worth looking at.

I read somewhere about someone else noticing caffeine affecting their BG - they changed to decaf and saw their BG come down.
Do you change anything else in your regime at the weekend? As my job is office-based, I tend to move around more at the weekend which will reduce my BG.

Maybe - at weekends I have more flexibility as to when I can exercise so that may be a factor.

Do you sleep more at the weekends.
I also make better food choices when I am well rested.

I don’t think this is down to food choices. Sleep may inherently improve the numbers though - it is healing.

@DavidGrahamJones - that’s ok. You clearly needed to vent which is always ok. I bet your readings went up whilst writing it.
Yes - stress may be a factor. I have more of it than I sometimes acknowledge

Thanks @DavidGrahamJones - I use the MySugr app on my phone so the record keeping is easy. I uploaded the results into a spreadsheet to create the chart but it only took a few minutes. It’s a great app.
