I ate too much again last weekend which embarrassed me because I already wrote about the six starters and the force-fed walk home, and I did it again with my own fridge standing open at midnight while my chatbot sat open in the next tab waiting to summarize something I could have read in ten minutes. Each excess feels tiny while it happens, and most times I notice the damage only the morning after.

A paper which landed in Cell on September 9 pulled me up short, and it comes from Marta Grońska-Pęski with Gilad Evrony at NYU Langone and Jonathan Shoag at Cleveland plus teams at UT Southwestern and the National Institute on Aging, and they fed mice thirty percent fewer calories than free feeding allows and then read the genome with high fidelity duplex sequencing which catches typos with great accuracy. And they found fewer substitution typos where one letter swaps for another plus fewer insertion and deletion typos where letters go missing or pile up, and the drop showed up across several tissues and cell types for the first time at genome scale. I am no expert so please take this with a bag of salt, but the method rang true to me.

In plain English; eat thirty percent less and the genome collects fewer copy errors in more places than we had measured before.

Liver calmed down more than kidney and kidney more than brain, which makes sense because each tissue damages and repairs DNA in its own way. And the surprise lives in the quiet stretches, because the biggest drop came in the least active regions which hold idle genes or empty sequence, and the authors guess eating less lowers damage everywhere while busy regions already repair themselves so often they gain less from the help. Its so neat to see the idle corners benefit most.

It lands inside a thread I have been pulling for years about abundance eating us, and my grandmother in Bengal kept sugar in a small jar on the highest shelf because it cost too much to waste, and sugar now hides in bread and cereal and granola bars which pose as health food, and diabetes now sits near the top of our modern miseries. Paracelsus said five hundred years ago the dose makes the poison, and the Greeks carved nothing in excess into stone at Delphi, and I keep thinking absence rarely gets the blame because surplus does the killing quietly (or atleast it seems).

I wrote about retatrutide fixing the energy cycle one receptor at a time, and GLP-1 quiets the inhale while glucagon lifts the burn, and I cycle Vitamin D and Omega 3s to hold my mood steady through serotonin synthesis and quieter neural noise. All of those feel like repairs after the flood, and this mouse result points closer to the source, because less coming in means fewer letters scrambled in every cell which carries the blueprint forward. Why? Because damage starts upstream of repair.

Less noise going in means less noise written down, and I want to keep tripping toward that quieter input for a while longer.

I close the fridge a little earlier tonight carrying that image of typos fading in quiet regions. Do we need the extra serving for this part of being alive? I don’t think so!

What would you stop reaching for if your genome could feel it? Let me know what you think, I am @troysk704.
