I finally got around to buying a glucose meter and I have been playing around with it lately, and it seems like my blood sugar jumps all over the place. I tested yesterday morning after an overnight fast, and my blood sugar was 92, I then ate a breakfast of chicken breast, sweet potato, onion, and asparagus (60 grams carb) and an hour later my blood sugar was 100, 2 hours later it was 92. For dinner I ate a pound of ground beef with 2 carrots, one sweet potato, and half a green papaya, and my blood sugar didn't even budge, it stayed at 92.
I forgot to check my fasting blood sugar this morning and I ate a typical breakfast of salmon with a small green plantain and two carrots, this was about 42 grams of carbs and the same amount of protein, this was at 7 am and I didn't eat again until 1 pm. Right before I ate, I measured my blood sugar and it was at 133!! I cooked about a pound of sweet potato and ate it with coconut milk and some gelatin, around 83 grams of carbs and measured an hour later and my blood sugar was only 114.
What confuses me a bit is the fact that I had a high reading 6 hours after eating my breakfast. I would think that my blood sugar would be low from lack of food but it was the opposite way around, eating a high carb meal reduced my blood sugar. Is this possible? Was my liver pumping out glucose into my blood stream during those 6 hours? Elevated cortisol.
I have been testing today and my fasting blood sugar upon waking up was 85. I ate a big breakfast of about a pound and a half of sweet potato, 8 ounces of chicken breast and a bit olive oil, and an hour later my blood sugar was 77!! WHAT THE $@!^... Why was there no spike???

I'm not sure what you are wanting to hack.
Normal blood sugar after a meal is 70-200 1 hour after, and 70-140 2 hours after.
If you don't eat your blood sugar is maintained by glucagon and insulin. You only have a spike of cortisol if you become hypoglycemic. Although cortisol is a normal part of glucagon release, but it does not indicate an elevation of cortisol.
As for the lack of blood sugar spike, because you ate so few carbs, and only complex carbs, it is likely that your body hasn't broken down the sweet potato into useable parts yet, however insulin is automatically turned on as soon as food hits your mouth, sometimes if you simply think of food.
There is nothing to stress about unless your becoming hypoglycemic( 69 or lower) or hyperglycemic(200/140 or higher) before, or after meals.
Fasting under 110 is considered normal, fasting 85 is ideal.
Your blood sugar goes so high because you wait so long to eat and adrenalin/cortisol goes high to break down your glycogen or muscle tissue(if glycogen is low). Eat more frequently and you should have more stable numbers.
For the most part, everything looks great. You can't always rely on the accuracy of the finger sticks. Next time you get one that doesn't fit your typical pattern, recheck it. Fat delays emptying of your stomach and it looks like you probably have good insulin sensitivity. The 114 was probably accurate, based on the other numbers you mentioned. The 133 is the only one that looks out of place. You are probably right about the liver and the cortisol, but 133 is more than I would expect.
I just asked a similar question and got some great answers:http://paleohacks.com/questions/106519/paradoxical-blood-sugar-test-results-in-a-young-healthy-non-diabetic#axzz1pxyyoSKu
This is just normal fluctuation. I've raised my blood sugar 100 points in an hour under stress. Food isn't the only factor. The problem is having blood sugar sustain at a high level even when fasting. A more stable measure of metabolic syndrome is A1C which does not fluctuate as much as blood glucose does.
