The problem is a fasting timer that ignores the last plate. People google circadian fasting and get melatonin charts. We do not read your sleep ring. We do not align meals to a pineal gland. Late food still has calories. It can also wreck tomorrow's appetite. Option 1 is Khatwa. Photograph dinner. Ask the coach what is left before the snack. Free on iOS and Android. A dedicated fasting app is option 2 if you only want a countdown and you will log food somewhere else.
What we will not claim
We will not say late carbs "literally block fat-burning enzymes." We will not publish a sleep-to-window table. If eating three hours before bed helps you sleep, do that. Log the window you actually used. Fasting plus a log: intermittent fasting and calorie tracking.
