This is interesting, as spike caused by pain & discomfort, of riding the MC.  Took a surfside ride, and after 15 ish minutes, very uncomfortable to painful.   Pain, inflammation & stress will spike you Glucose.

 

 

 

Yes, an expected spike on empty stomach vs previous night no effect, after heavy fat & protein meal & snack.   What, when & how you eat makes  a huge difference. 

 

Could have negated that spike by eating a couple eggs prior to the Croissant.

Couple observations, for my O&A, 'go to',  7-11 munchies, and 3 regular ready meals, 2 burgers are OK, since eaten so infrequently ...

... Chicken KraPao Spagetti

... Chicken Tikka Masala

... Korean Chicken & Rice (Turmeric)

... Fish Burger

... Double Pork Cheese Burger

 

And NO, not what I eat every time we stop charge the BEV, as other options available at the PTT Parks, though TBH, not sure if they are any healthier.   Maybe 5 Star Chicken, without the sticky rice.  

 

Of course the Caesar Salad w/ added Smoke Chicken is obviously a better choice.  Along with 7-11 also sells Hard Boiled Eggs, to eat first to lower any spikes 👍

 

Cheesecake always a better choice for sweet tooth fix.

Avoid Pringles, and Lays a better choice.   Even better, stick with the Cashews.

 

Avoid larger servings of white rice, home or away.   The Tikka Masala comes with smaller serving of Basmati rice w/veggies vs the high spiking Chicken Massaman, that had large serving of white rice, and Chicken Massaman part had more potato than chicken.  First & last time I sampled the Massaman.

 

All common sense, and nice to have confirmed by CGM.  Eat the Carbs & sugars, after the fats & proteins.

 

Biggest surprise ... Dim Sum Bbq Pork Buns, on empty stomach, AVIOD doing that again.

 

Far from my normal in home, whole food eating lifestyle, and as crappy as most was, CGM telling me, I'd still only register about a 6.3 HbA1c blood test.   Pretty high, but still not diabetic territory, though not someplace you want to be consistently.

 

 

 

Misread the CGM, have till 1030 hr 25 Oct to keep using., not done today.   Normal lunch (brekkie), except had the Croissant on empty stomach few hours earlier, as my 'break-fast' 🙄

Back to normal eating, and just the one 'testing' spike on empty stomach.  Usually I don't eat anything till 1100 hrs.

@fredwiggy  Got me curious, as haven't checked my BP in quite some time ...

 

Grilled Cheese on empty stomach, not the best choice ...

A clear winner, Steak & Eggs w/ toast or a Grilled Cheese, 2 slices Makro whole wheat & 3 slices of 'cheese product' ... hmm

 

Calories of Steak & Eggs, toast ... 630

Calories of Grilled  Cheese ... 375

 

 

A simply Peanut Butter & Preserves is even worse 

 

25 October Coffee

0505       Grilled Cheese – 41.4S

0756       Peanut Butter & Preserves – 50.4S

 

Low at sleep was 5.0, exert a little energy, dog & myself up for a P, make coffee & Grilled Cheese and up to 5.9.   Eat the Grilled Cheese, spike up 41.4 mg/dl.

 

Back down to baseline, 5.3, eat the PB&P, spike up 50.4 mg/dl.

 

Think I might have time for one more test, before CGM 'expires', if baseline gets down below 6.0 at least as now at 6.6, and heading downward.   Want to test Roti, hopefully before 0945, as CGM expires @ 1039.  Give it time to spike, before heading downward.

 

EDIT: down to 5.7 already.   At least they are short spikes.  Takes about 30 mins to peak, then about 30 mins to get back down to reasonable baseline.

CGM officially 'expired' ... BUT ... 24 hr grace period allowed, not sure how that works, though they do recommend buying another, so no data is loss ... big surprise.   NO THANKS

 

I can highly recommend this Ottai CGM though, especially if concerned about being pre or diabetic, if not already.  Readings every 5 mins.   Can't beat the price point and very user friendly 👍👍

 

Think I got all the info that I need.   Actually eat fairly healthy, most of the time, which is nice to be confirmed, though blood work does that, along with a scale & mirror.   Really can't think what else to test, as abused myself enough already 🙄

 

Did learn a few things, and better choices obviously pointed out, like below.   I can enjoy any of those 3 items, or simply eat Steak & Eggs, with homemade whole wheat toast & butter.   Hmm, let me think  

 

1221       Steak & Eggs, w/toast – 21.6

Spike ... Spike ... Spike ... "How to be a Diabetic 101"

 

 

Back to a normal, overnight fast, as last snack was 1900 hr.   Made a huge different in overnight glucose, as dropped down to one of the lowest in 2 weeks, 4.4.  Same with first to days of using CGM, which were 4.2 & 4.5.   Before I started testing and eating silly.

 

Most times, at 6.0, occasionally 5.5.   So a whole 1 to 1.5 off the baseline, across the board for almost week, with much less food, carbs / sugars eaten, and my HbAic would be closer to my normal, 5.3+/-, instead of the CGM's estimate of 6.3.

 

Amazing I can eat that much, that crappy, and still not be in diabetic territory.  Now that awake, and needing energy, up to 5.4, which is still lower than most of my overnights, the past 2 weeks.

 

I think not having a late night snack, or sipping beer till late night makes a huge difference, as overnight fast would have nil effect, especially if eat brekkie when most do, just after waking.   Couldn't call that a fast.

 

I normally wouldn't eat till almost noon.   Will do one test today though, as CGM still active till 1039 hrs.

 

 

 

Had Pizza Co pepperoni pizza for dinner, and last snack, and didn't spike as high as I expected, but I do consider pizza a healthy food, especially with the added fat & protein of the pepperoni 🙄

That pretty much wraps this thread up.  My morning test will be whole wheat toast, butter, honey or sugar & cinnamon, and should be good for a nice spike.   Not sure if going to eat my eggs first with it.  Which usually lessens the spike 1/3 or even 1/2 of.

 

My first night using, on normal overnight fast, and not eating till almost noon.   Then the testing began 

 

Rest of the 2 week ... well, nuff said 

Starting eating some days at 5 AM  

 

Tik Tok ... 😭

 

 

Last test and already spiked up to 8.7, and coming down, from 5.8 = 52.2 mg/dl

 

No surprise, as not nearly enough butter to negate the carbs / sugar load.

When I get bored, I'll post all the info for past 2 weeks, foods & graphs, for anyone interested 🙄

I don't claim to be an expert, but I am not convinced we need to be constantly monitoring our glucose levels.

 

Here is why I think that.

Some foods which spike glucose levels may be much healthier than others, despite similar glucose rise levels.

 

For instance, fruit may spike glucose as much as a piece of cake.

 

The difference is that the fruit has many nutrients, but the cake has harmful substances. The harmful crap in the cake will impair your metabolism and ability to process healthy carbs in the future.

 

So my point is just need to identify foods that are harmful and limit them. But some foods like fruit which also spike glucose levels quite high, or even potatoes, aren't necessarily harmful.

Agree 100%  

 

Was just a 2 week+ test for me, as curious more about 7-11's offerings.   Surprised that my choices from, weren't bad at all.    Though keep it to when O&A, as not as healthy as our whole food home eating lifestyle.  Too inexpensive (฿1050) not to use, as filled in the gaps from the YT'er that has channel testing all things healthy or unhealthy.

 

Also think some things demonized, are better, healthier options, such as pizza.   Can also minimize the spikes, by when, how, in what order you eat, and a stroll afterwards.   Pizza I ate yesterday, early dinner spiked as expected.   But the snack a few hours later, did not, but I went for a stroll in between, raising my metabolism, and carried over apparently. 

 

Intermittent fasting makes a huge difference, and start the day with a very low baseline, while them super ketones burn fat overnight 👍

 

Was nice to compare different options as better choice, as one post pointed out.   Can eat Steak & eggs w/toast, better than one small carb snack.   Pretty eye opening.

 

If diabetic, then I'd probably have one 24/7, as just too accurate and less hassle than poking yourself all the time.  Give you an alert every time you reached any hi / lo threshold, and probably needed to avoid any oops.

Received a CGM on 11 October, good for 14 days of monitoring my glucose.  Can't recommend it highly enough, especially for you pre or already Diabetics.  Constant, every 5 min readings of glucose level.  Not subscription / monthly service, just a one time buy, from LAZ (Total ฿1,054)

 

Link:  https://www.lazada.co.th/ottai-health-global/?q=All-Products&from=wangpu&langFlag=en&pageTypeId=2 

 

I follow the one YT'er, that I've posted many times, so not testing what he has already tested.   Only testing my carb heavy meals, and 7-11 favorites that I only eat when O&A.  Tested 5 already, ready meals & burger.   Have another meal to test, then about 6 treats; dessert & snacks.   All things I do NOT eat when at home.  Two things we do eat, Pizza Co Pepperoni Pizza & Swensen's 2 scoops.   Then I'll be done testing, what some consider 'junk food' 🙄

 

Then last few day of having the CGM, will eat normally, hopefully, though don't expect any really surprises with my home cooking.

 

Only had 1 major surprise, Dim Sum BBQ Pork Bun ... spiked 90 mg/dl

 

Any spikes < 25, and nothing to be concerned about.  Spike of 30-40, limit those to couple times a month.  Over 40, try to avoid.  So far only the Pork Buns, and one home cooked meal (48 mg/dl), the latter was more about serving size, and really should have been 1.5 - 2 meals.

 

Rest have been as expected, < 40 mg/dl, and not surprised, since most of, was rice or pasta, and the bread of the burgers.

 

 

How accurate and good is a $40 machine vs what is apparently is meant to cost?

 

From Google AI:

 

Continuous Glucose Monitor (CGM) costs vary widely, from around $50 for trial/OTC options like Lingo to $1,200-$3,600+ annually without insurance, depending on the brand (Dexcom, FreeStyle Libre), sensor life (7-14 days), and if you use a smartphone app or separate reader; insurance significantly lowers costs to potentially $0-$75 monthly, while programs and discounts help cash payers. 

 

Typical Costs (Without Insurance)

• FreeStyle Libre 2/3: Around $160-$170 for a month's supply (2 sensors), totaling roughly $1,900-$2,000 annually.
• Dexcom G7: Roughly $3,000–$3,500 per year for 10-day sensors.
• Medtronic Guardian: $2,500–$3,000+ annually for 7-day sensors.
• Eversense E3: Higher upfront cost but long 180-day sensor life, potentially $2,500–$4,000+ yearly.
