FAQ
What is OMAD or 23/1 fasting?
OMAD usually means one meal a day. A common timing shape is roughly 23 hours fasting and about one hour for that meal.
Is OMAD the same as calorie restriction?
Not automatically. OMAD is a timing pattern. Calories and protein still depend on what you eat in that meal.
Can Limotein track OMAD?
Yes. Use the 23/1 OMAD window, start the timer, and keep the countdown visible while you fast.
