Schedules · One meal a day
OMAD · 23:1
One meal a day, inside roughly an hour. A demanding schedule to keep to, and harder to fit around other people’s mealtimes than the shorter protocols.
One example day
Eat between 19:00 and 20:00, then fast 23 hours until 19:00 the next day. Any window that fits your day works the same way.
