This is a really elegant framework, and I love that it gives people something clinically accurate to do in the gray zone between “I’m fine” and “I’m clearly sick.”

As a physician-scientist, the “buffer” concept is exactly how I think about early drift: most bodies can absorb sleep debt, stress, glycemic swings, and under-recovery, until the margin quietly narrows and you start feeling “off.” Shifting from diagnosis-hunting to which buffer is underpowered (sleep, stress, nutrition/blood sugar, recovery) is a far more actionable first pass.

Your “one change for one week” rule is also underrated science: it’s basically an N-of-1 experiment with clean signal. When people change five variables at once, they get noise, not insight and they end up attributing causality to the last thing they tried.

The only nuance I’d add for readers is your own guardrail: this process is fantastic when symptoms are subtle and stable, but it should sit alongside a clear “red flag” threshold (new/worsening chest pain, syncope, focal neuro symptoms, GI bleeding, rapid weight loss, fevers/night sweats, etc.) where evaluation comes first.

This is exactly what folks need! I love how the buffer framework shifts the focus from chasing diagnoses to actually understanding where your system is strained. I've used similiar approaches with paitents dealing with chronic fatigue, and yeah the one-change-at-a-time method is key. The tricky part is getting people comfy with that level of self-observation when they've been trained to just seek external validation.
