the energy breakdown visualization is solid but it assumes steady-state fuel switching. my glucose tracking tells a different story - readings stabilize around day 2, then stay flat without the crashes the estimates predict. tbh real question: when does protein catabolism actually accelerate? glycogen supposedly depletes in 24-36h but my numbers don’t show the expected instability. tirzepatide changes appetite obviously, but the metabolic piece feels underspecified. anyone else tracking actual markers instead of estimating? fasting glucose, ketones, whatever you have access. estimates are useful baseline but the data gaps are worth acknowledging.
