Imme_Play_5550on ChatGPT Health

I have no job and no health insurance. After crafting my prompt correctly (I have W symptoms, X blood markers, have Y lifestyle, and Z demography) ChatGPT accurately diagnosed my problem. (You have REDS and need to eat more food, dumbass.)

Or, I could've gone to a doctor and overloaded our healthcare system even more.

ChatGPT serves as a good sanity check.

Imme_Play_5550on Show HN: Ten years of running every day, visualized

Just gonna say, as a fellow excessive exerciser... exercise doesn't make you stronger. It's the recovery afterwards and the resulting growth/adaptation that makes you better.

Don't let rest feel like weakness. It’s where the real progress happens.

Imme_Play_5550on Show HN: Ten years of running every day, visualized

There is definitely such a thing as overtraining. I got my free testosterone down to 15 (reference range=35-155 pg/mL) and my total testosterone down to 96 (ref=250-1100 ng/dL). From histograms from various studies, I hit the 1-percentile of low testosterone as a 35yo male. That's... uh... not good.

This was due to a number of factors: excessive running (the equivalent of ~50-70mi/week), calorie restriction, and possibly carbohydrate restriction. Thankfully symptoms of low T (namely morning erections) resolved ~1month after ameliorating those 3 factors. (For anyone interested, look up "Relative Energy Deficiency in Sport".)

Mileage isn't my goal. Health is.

OP states "I've... invested into my own health", but I'm not convinced.

Imme_Play_5550on Continuous glucose monitors reveal variable glucose responses to the same meals

My mother and I recently did an oral glucose tolerance test while wearing CGMs and discovered that in us, the CGM measurements (Dexcom G7) and the reference instrument measurements (whatever Quest Diagnostics uses) virtually _never_ lined up, even when including the G7's advertised error margins. The blood glucometer readings in me didn't line up either. Admittedly this was on the first day using the G7, when it's apparently less accurate, but due to this I've been doubtful of CGM readings in me/her. I'm sure CGMs work on a population level, but for us, on that day? Nope.
