I've tried a handful of times but haven't managed to integrate it as a regular habit.
I'm OMAD, but I got there in stages.
My recommendation would be to first consider switching to a ketogenic
diet. This makes it easier to fast. Then shorten your eating window to
whatever works for you (8/16, 4/20, etc.)
My progression over a 3-year period:
- low-carb
- keto (3 meals/day)
- 2 meals/day + recovery drink after morning workout
- morning recovery workout drink, 1 meal (dinner)
- OMAD: 1 meal/day (usually dinner at 6pm)
This seems to be working for me. I don't have any cravings and the progression
made it easy to go from one stage to the next.
I'm also doing a 3-day fast on a monthly basis, and will possibly consider an
annual 7-day fast.
Honestly, the hardest part is social expectations. I'll join family/friends, but
often just order coffee/tea if it's outside of dinner. Easy to do for breakfast,
since lots of people skip it -- harder for lunch. Sometimes I eat lunch with
friends, then skip dinner, but this kinda throws me off a bit.
Benefit #1: When I travel, everyone else is urgently worried about what food
they can get on the flight or what's available at the next road exit. OMAD
saves me from eating a lot of unhealthy food, but even if I end up at a fastfood
restaurant for dinner, I don't sweat it.
Benefit #2: When you're only eating one meal per day, you have more time
to prepare quality food at home, and I don't mind spending more for quality
ingredients.
