Default Rob help, fasting glucose question

I am pretty lean my thickest of 7 site skinfolds is 5mm several are at 3mm. 6ft 177lbs.
I had a glucose machine at the office today and got the following results
96 9am 14 hrs fasting
98 10 am 15 hrs fasting
104 11am 16hrs
worked out ~45 min low rep DL, squats, pullups, pushups
86 post workout @13:30
97 15:00 20 hour fasting
ate 4 block meal salmon, canola oil, oatmeal (I know not Paleo) ate at my desk 1520-1550
142 glucose at 1610, 20 min after meal finished
97 @1630

When I have labs drawn my insulin is below lab parameters <2, glucose is usually high 80s to low 90s, HbA1C is 5.4, trig 43 (lab normal <145). I normally eat close to Paleo with relatively low carbs maybe 22 blocks protein 10 blocks carbs and lots of fat est 3-4x. I assumed my glucose would be lower like in th 70-80 range.

I find it strange that my glucose rises the longer I fast, I have not checked it first thing in the morning yet I assume it is even lower but just a guess. Is this normal?

For the heck of it I did frequent glucose readings today non-fasting day and here are the results:

88 glucose 5:00am (10hours since last meal)
93 6:30am (11.5 hrs since last meal)

4 block meal 6:45am, worked out 7:10-7:40

87 8:10am
96 9:15

3 block meal 10:20-40

104 11:20am
110 12:25 My little finger is looking pretty beat up from doing all these sticks

4 block protein and fat 3 blocks carbs @13:20-40

99 @15:10
97 @15:55

Craig-
I think Sarena hit it...likely a bit too much stress. All of this stuff is so new it's tough to know what is the "right" way to go but if you add fasting to poor or inadequate sleep and or a stressful environment that could be enough to get a dose of cortisol and get that blood sugar up. keeping an eye on the hb1ac is good for ferreting this out.

Keep us posted!

Results from another day of glucose testing. Not sure if this thread really still belongs under IF section or not, but.

Night before I went to Dairy Queen and had a pecan cluster blizzard, about 500-600 cals of dairy and sugar laden delight. (I have not had one of these for almost a year). The next day...

83@550
2cups black coffee 6-730
83@730
ate 3blocks oats/berries/protein/flax meal ~740
short w/o
89@1000
ate 4block meat/veggies/laura bar ~1130
87@1240
1330pm Movies kettle corn, steak (yes I brought leftover steak into the theater in a zip lock bag and ate it), diet coke est 4 blocks
103@ 1630
ate dinner steak, cauliflower, yam ~5blocks ~1900/7pm
93@ 2130/930pm
ate 1 block flax berries protein powder

There is one big difference in that this was a relatively relaxing day off work! The other time when I was fasting and had levels I did not like was a day at work which is usually pretty high stress.

Of particular interest to me was that even my postprandial readings were better than fasting levels the other day. This is definitely not a normal day for me as I had many non-paleo/zone non-favorable carbs.

I must say that your readings after the movies (and Diet Coke) are pretty darn interesting.

Craig-
A more consistent eatign pattern OR somehting like a compressed feeeding window (last meal at 5pm, next meal at 8am) or somehting like that may be a better option. We are not wired for chronic stress (like damn dirty work!) and fastign can certianly exacerbate that.
