I am new to this, and very recently diagnosed. I have just started to monitor my blood sugars and I have a bigger difference between pre and post food readings for my evening meal than my "break fast" meal. Could the timing be a factor? Other information: I am eating a LCHF diet. I tend to exercise more in the morning before my first meal. I do some exercise after each meal - more after the first meal than the second. The first meal of the two meals a day I eat is after a 16+ hour fast. There are a lot more grammes of protein in the evening meals and these do seem to correlate with the readings on the BG monitor. Has anyone got any ideas about what is happening here? Here are my figures for the last two days. 06/05/2018 9.53am - 7.3 (fasting reading) 11.33am - 7.3 (before food) 1.48pm - 6.7 (after food) Difference - -0.6 4.40pm - 6.8 (before food) 6.43pm - 9.7 (after food) Difference - 2.9 07/05/2018 6.02am - 8.6 (fasting reading) 12.08pm - 6.5 (before food) 2.10pm - 8.0 (after food) Difference - 1.5 6.24pm - 6.7 (before food) 8.25pm - 9.4 (after food) Difference - 2.7 I know you need to look at things over time, but this has got me puzzled.
