What do the "O" and "M" stand for in OMAD?

[collaroygal]

It’s a single meal. If you get up and do something else it becomes an eating window instead.

This is my idea of OMAD and TRE as well.

I have found OMAD not that helpful. I tend to do ADF more than OMAD. I followed a OMAD group for a while, most there were using 1 hr. a day for their eating window.

If I could have done ADF I would have. But for me it was too hard. I just can’t sleep hungry, and for some reason my hunger becomes insessant at night. Maybe it’s because my starting weight was too low, I don’t know. But it never changed. Even now a 48 hour fast is very hard for me.

Carnivore omad’er here. Or lets just say “warmad”…i heard the Fledge Fitness guy on youtube use that word. He defines it as doing your omad within a 4hr window. I take between 1 to 3 hours to eat my Omad. Sometimes 4. I still consider myself an omad’er if it takes me 4 hrs to finish. My avg is usually two hours though. I typically do my omad between 830 and 1130am…no need to rush. No need to hurry. But i still have a window, it just may vary depending on the day .

Ongoing Meal All Day

[MarkGossage]

However long it takes me to eat my steak…
If I have something else later… then Its not one meal.
I’m intermittent fasting or time restricted eating. I’d say 30 minutes or less for the “one meal” window .
4 hours is TMAD at best.

[FrankoBear]

OGod, what’s OGAD? Eegads, what’s OGAD God to do with OMAD?

All rhetorical of course.

I’m surprised no one brought up insulin. Maybe I missed it? If you drag out one meal over 4 hours then you’re not taking advantage of the opportunity that OMAD over 30 minutes offers with less insulin production. Right?

I wonder about the biochemistry. We have insulin rise after we eat. Maybe the frequency is determined by insulin peaks? Using the proxy biomarker of blood glucose level.

That’s probably what @SomeGuy Joey was saying? ISCFTOA (I still can’t fathom the OGAD acronym)

Here come the carnivores and their flatline continuous glucose monitor graphs.

Only Meat All Day

One Meal a Day --but the other answers are creative and fun…

Sorry, but your blood glucose “spikes” are only excursions up to what most physicians would refer to as normal. ALmost all of these data are low or what would be called dangerously low. Now of course that label doesn’t really apply for how you are eating and likely ketosis levels but the term “spike” in blood sugar monitoring usually refers to an increase to levels above 125.

Pretty amazing numbers.

How about this… ages ago there was a book called The Carbohydrate Addict’s Diet. In its original form (it got bastardized later), you ate 1 or 2 VLC meals per day, and then whatever you wanted for 1 meal, but it had to be completed within an hour. The 60 minute limit was a hard and fast rule because of the body’s two-phase insulin response.

According to the book, the first insulin response comes when you start eating and is kind of a lowish ‘guess’ because your body really doesn’t know what’s coming. After 60-some minutes your pancreas takes a look around to see if you are still eating. If you are still eating after 60 minutes, the pancreas figures this must be some kind of feasting situation and cranks out a second, bigger dose of insulin.

So based on that idea, ‘one meal’ should be less than an hour long.

I will say though, every time I have heard Megan Ramos say OMAD doesn’t work, she gives the reason that it is too predictable and the body adapts. It isn’t that there is anything inherently wrong with that particular timing, just that is becomes a routine for many people.

I was putting “spike” in quotes because I know it wasn’t a real spike. I was using it as a descriptive term to describe the sharp increase.

[Fracmeister]

I know. Sorry if it wasn’t obvious — that’s why I commented on how great the numbers are…

[KetoCancerMom]

Its OK.

I’m getting back to good numbers, now that I started the Metformin. The Piqray was really messing with my glucose.

I still have that in my book case. I ended up losing a few lbs and then it not only stopped working, I gained like 10 lbs. over what I had lost. Keto/lchf and fasting is what got me where I am today. That allowance of any carbs you want really did me in. I should just toss out that book, not sure why I still have the darned thing, oh yeah, I hate letting go of any book, I’m a total bookworm. LOL

I probably never will decide what is OMAD for me - and it’s fine. I don’t need labels very much and usually my OMAD is IF 23/1. But not always. I easily can have a 2-3 hour long meal, of course, it’s not eating all the time but I actually am in the kitchen, preparing meal and whatnot (yeah, I have too much free time but it’s not an everyday occurrence). Lunch is the family meal, talking, having fun with cats, making another dessert or omelet or whatever… It’s not like I have my full meal in front of me when I sit down to eat. I am super bad with a single dish or two, it’s borderline impossible.
So sometimes I have a 2+ hour long meal and it’s kind-of OMAD to me but I like to call OMAD my 23/1 days, with almost nothing else outside of the window (I don’t consider eating 2 rosehip berries or 2g lard having a second meal but that’s it).
It’s a bit fuzzy and some people are very relaxed with OMAD. I don’t think a 4 hour eating window or drinking coffee with 1dl heavy cream is OMAD at all but I don’t really care. I am used to people having interesting ideas. I am only sensitive to self-proclaimed vegetarians deliberately eating animal bodies, they are a big reason why people was unsure what I ate as a vegetarian, it makes communication very hard.
