🍽️ New study on time-restricted eating is making noise, published in #sciencetranslationalmedicine — but here’s a more nuanced look 👇

This 2-week trial did not improve insulin sensitivity… but the conditions were NOT isocaloric as intended.

Late TRE also delayed circadian timing (~40 min), but the measure was a surrogate, right at the limit of detection-replication required using gold-standard DLMO methods!!

🧠 Takeaway:
Two weeks is too short to judge metabolic effects — and longer TRE studies already exist (but weren’t cited).

A day in the life of academia
Catch a quick run before sunset
Work on lecture in dim light
Computer fails while giving lecture
IT doesn’t help
Take fiddle walking

⚠️ We’re seeing many products marketed as “sleep research.”

🧠 If you can’t find:

A peer-reviewed publication

A defined population and protocol

Transparent reporting

…then it’s not research — it’s marketing.

💤 Science communication matters because misinformation confuses patients and clinicians alike.

💤 Does the melatonin dose on the bottle match what’s actually inside?

A 2017 analysis found that melatonin supplements often contain far more (or less) than the labeled dose 😳

💡 In the U.S., melatonin is sold as a dietary supplement, not a prescription medication. The FDA requires that the listed dose be accurate at the expiration date, not when you buy it.

🕰️ And remember — timing AND dose matter:

Evening (0.5–1 mg) → advances your circadian clock (useful for eastward travel).

Morning (0.5–1 mg) → delays your clock (useful for westward travel).

Higher doses (2–10 mg) don’t necessarily work better and can cause next-day grogginess.

🧠 Our take-away: Use melatonin strategically, purpose, timing, and dose all matter — and so does verifying what you’re actually taking.

Headlines this week claim that chronic melatonin use may be “dangerous” and increase risk of heart failure.

🧠 Remember this: it’s from a conference abstract, not a peer-reviewed study.

No causation, no clear mechanisms, and likely confounding factors at play. Details in post--Preliminary findings get exaggerated into scary health headlines?

Please stop the madness!! End arbitrarily switching the time on our clocks 2X per year. A little history and perspective on #daylightsavings

Consider the balance between morning light during the commute to school and work versus evening light, hopefully for #exercise
