Are you a Garmin user? I wonder how the VO2Max estimates compare.

What I have noticed is that an easy paced ride (say Z2-3) causes my sugar to go down into a good zone (about 100-ish) and stay there, while a harder ride (Z3-4 with occasional anaerobic bursts) causes my sugar to spike to 150-ish (because adrenaline) for an hour or so, and then it gradually works its way down to 100-ish. I did a 90 mile really hard ride and did not have any low sugar concerns, although I ate reasonably well for it.
Maybe I am too skeptical, but I believe these units are GREAT for folks with diabetes (especially with T1DM and when the sensor is integrated with an insulin pump) to track what actions raise and don't raise their sugars, but for an athlete I don't see much use.

The simplest estimation technique is HRmax/HRrest x 15.3. That gives me a VO2max of 53.

Also, are you finding it effective at other times to blunt the highs? My brother has mild T2DM, which he's controlling with diet and exercise, and maybe should have one.

So, ignorant question here: Given the ability of brain, skeletal, and cardiac muscle to metabolize lactate and ketones, which are abundant during prolonged exercise, would a somewhat low glucose even be a concern?

I have IFG (pre-diabetes) and I notice that if I have a naughty snack between meals (like that donut I had last Tuesday), my sugar really spikes (up to about 180) for an hour. So I think it could be very helpful as a feedback device to discourage such naughtiness, in a person who is motivated. Again, most useful for T1DM for insulin dosing etc. That's my sense.

I suspect that our homeostatic mechanisms keep sugar reasonably well controlled, but I also suspect that after several hours of hard work and inadequate calorie intake, when one is bonking or on the verge of it, sugar may dip. That is my best guess about what this might actually be useful for.

Sadly, onion and garlic now do bad things to my stomach (and AG's) and that wipes out essentially all pre-made sauces and spice mixes. Fortunately, Buc'ees sells good huge salads and you can buy chicken and cheese to put on top. Better food than you can get at any other place for a restricted diet. Of course, they also have more interesting fare for those who can partake.

I have the FODMAP thing too, but to whatever degree I have it, it’s worth eating the stuff except in the most extreme cases.

In the last couple of years, I switched to oat milk, from cow milk, in my morning lattes. In doing so, I discovered that the, uh, coffee effect was actually a dairy effect. While this has been a welcome discovery, I must admit that it makes my morning weigh-in a little less streamlined.

Dairy that's a little more processed, cheese, yogurt, ice cream, etc, might make me feel a little bloated when consumed in sufficient (relatively high) quantity, but only straight-up milk will result in the effect. Then again, the only time that I drink (drank) milk was with the morning latte, so maybe it was just a daily perfect storm - a circadian readiness paired with a dairy pat on the back.

I was going to say, "I wish that I had friends like that," but I know brewers, so I'll just be happy to count my blessings.

Hey WhyFi , Intervals will now estimate your VO2max and mine agrees with HRV4training.

no, but curiously I just finished ironing tomorrow's pants and shirt.
On a side note, I go to the cardiologist tomorrow for my anticoagulant monitoring. I hope to get an at home finger stick test kit. I'm going to look like a smack junkie if they keep tapping my veins every week. SM*H
At least I have my weather app with its superior accuracy to bring some sunshine into my otherwise s****y life.
