I've been primal/paleo for a year and a half, and have about 8lb to lose.
So I decided to try this 2 days ago.
The first day went ok. The second day, I decided to test my blood glucose.
I had a breakfast of 1lb. Yukon golds.
1/2 hr 136
1 hr 181 (!!!)
2 hr 94
Way too high! I tested the 1 hour twice, so it's no mistake. Needless to say, I immediately quit the diet.
I recommend all of you to test your glucose.
Since hubby is diabetic, but controlled (mostly) by strict adherence to low carb eating, I access his meter from time to time. Although my sugar levels tend to bounce quite a bit, they have been sneaking down and down, what with adding more fat and cutting protein.
Last week I was startled to find my levels down below 4 (72). They've since recovered a bit, so has my busted rib, and I think another tater experiment is just around the corner. But you better believe I will watch sugar levels like a hawk. However, for a diagnosed diabetic, your numbers are considered not only acceptable, but good if on no medications right after meals. It was under the 2 hr limit when your sugars reverted to 96. (Not that I accept my doc's reassurance that hubby's numbers are great, either. I've seen them too high - like 7.4 (fasting overnight after taters for last meal) shoot right up into the teens and stay there for too long). I think he is allergic to potatoes (a sad fate for an Irish descendant) and hadn't served only miniscule amounts for years. He won't try moar potatoes when I do.
65lbs gone and counting!!

Then I took it a step further. I ate 1 pound of potato and tested at 15 minutes intervals. It makes a really cool graph! My glucose was: 90 (just before eating), 116, 116, 130, 179 (1 hr point), 150, 130, 110, 90 (2 hr point), 75, 68, 75, 80 (3hr point), 85, 85 (stopped checking).
This shows supreme insulin sensitivity! I would love to do it at 5 minute intervals, but those strips are spendy!
Another experiment I did was check my blood sugar after chewing and spitting out a big mouthful of potato. My blood sugar dropped about 10 points after 15 minutes...can anyone guess why?
If you had glucose intolerance/insulin resistance issues, eating a pound of potatoes would make a 15 minute graph like this: 90, 120, 180, 200, 250 (1 hour), 220, 200, 180, 180 (2 hour). Or similar. The test is what your blood sugar drops to after 2 hours--it should be close to or below your fasting blood glucose. Big spike is normal and OK.

Because you triggered an insulin release with the taste/expectation, but spat it out so the insulin was just storing what little glucose it could find?Another experiment I did was check my blood sugar after chewing and spitting out a big mouthful of potato. My blood sugar dropped about 10 points after 15 minutes...can anyone guess why?
