12-hour overnight fast
DeLauer frames this as the minimum non‑negotiable step to let the mitochondria ‘reset’ and produce metabolic water. He says even if you’re not a fan of intermittent fasting, just keeping a 12‑hour overnight window avoids constant glucose oxidation and gives mitochondria a chance to run on fats.
Lower insulin lifts inhibition on hormone‑sensitive lipase, allowing adipose‑tissue fatty‑acid release. A low‑energy signal activates AMPK and PGC‑1α, promoting mitochondrial biogenesis and shift toward fat oxidation.
We need to try to go 12 hours between dinner and breakfast.
