OMAD - does it have to be Keto?

(Stefan) #1


I’m currently doing OMAD, following Fung’s advice.
My simple question is: does the meal have to be keto?
In my mind, keto would allow me to adjust my body to use fat throughout the day, so probably the hunger would go away. Overall insulin levels would be lower.
But, if I strictly follow fung, the main thing seems to be to eat continuously.

Any experience from you guys?

Not eat continuously you mean I hope?

It depends on what your metabolic state is like but yes eating keto for your one meal will make it far easier to feel satiated for longer periods than wolfing down loads of carbs which is why keto eaters tend to be able to fast for longer than non -keto eaters.

Megan Ramos who works with Jason Fung says that their clients tend to not be able to do keto for social and economic reasons so they get them fasting first.

However, @Brenda who also works there says they don’t recommend OMAD because it can turn into calorie restriction which can reduce your metabolic rate.

There are plenty of people on this forum who do OMAD. I don’t routinely.

Keto + some form of time restricted eating (fasting) seems to be a good combination for my metabolically deranged system. I do OMAD occasionally, mostly IF 18/6 and one extended fast / week of 48 to 72 hours.
If you are keto and fat adapted you can fast longer and more easily.

I’m guessing that if you are keto your weight loss would be better but your mileage may vary.

OMAD isn’t advised long term, sometimes I do it but other days it’s 2MAD then some days nothing at all. Surely having a carby meal would cause a huge insulin response?

That’s right, for me it is also that for social reasons Keto is a real struggle.
I’m on omad now for one week and like it so far. Before, I’ve been on 16-8 Keto.
However, with omad, I tend to really eat huge portions during my evening meal

That’s only natural and there’s nothing wrong with getting all your dietary energy in one meal. But I agree with @Shortstuff about switching things up. Jason Fung often mentions this too. Mixing things up can prevent our bodies from slowing our metabolism by reassuring our body that famine is not a threat.

For me, I don’t eat to please others. If people don’t like the way I eat that’s their problem, not mine. Eating is a personal thing. Don’t use the excuse that “Well everyone else is eating this so I should too. Can’t you choose from what’s served to make your meal keto or arrange an alternative when something like pasta is in the plan for others? There’s plenty of people here who eat keto and the rest of their family doesn’t. They seem to make it work.

I’ve never understood the social aspect of eating. I eat what I want, when I want. We have a neighbor who is always pushing baked goods on us. I just say no thank you, that is bad for our blood sugar. I think she is finally getting the message.

Agreed… Some people are so ignorant of what food is and know nothing about the facts. My ex gf included… it’s sad.


I think we are all ignorant when it comes to food, that is why we struggled with it in the past and/or made bad choices that we are trying to fix now. We had to dig deep into nutrition and science, others don’t have the time or don’t want to…

Five years ago I had no clue bread, pasta ad rice were the problem.

I’m a frequent traveler. I go to one of my companies plants and they serve lunch. I eat what I get, or I don’t eat, which in some cultures would be unkind. In Germany, I get offered sandwiches, in Spain some keto friendly food, and so on…
I travel 75% of the time, so for me, social reasons are a thing.

Can you not tell them you have a gluten intolerance to encourage different food offerings?

(Stefan) #14

Good idea!

@steka I agree with this 100%, eating is absolutely a personal thing, so if you choose to do OMAD without keto I hope you might report back to share how it goes. I’d be really interested to hear the results.

You’re probably going to get lots of advice about how to do keto while travelling and how to stay keto strong when faced with a wider variety of foods, which I gather isn’t what you were seeking.

You’ll find information from people who’ve done OMAD with all sorts of foods/diets (even vegan) on youtube. There’s some really interesting OMAD stories on there. All the best.

I know of others who have said they’re diabetic so have to avoid sugar. Lying isn’t ideal, but if you’re determined to stay on track and aren’t comfortable explaining your reasons, it may be the lesser of the evils. I wish you luck finding what works for you :slight_smile:

This is an interesting question and one I was talking about today. I wondered if when I started this way of life how things would have turned out if, instead of eating keto and quickly getting into omad (because I’ve never been into breakfast and quickly wasn’t hungry until dinner) if I’d have just eaten ‘regular’ food and omad how that would have turned out. Obviously I don’t know but it would be interesting to know.


Perhaps reread. Fung does not recommend eating continuously at all, so perhaps you have misunderstood?

(Stefan) #19

No, mistyped. I meant, of course, to not eat continuously


it doesnt have to be keto on omad , many people have great success just eating whatever they want for there one meal , ive done both and always go back to eating keto meals in the end .
for me personaly if i eat a carb heavy meal for my omad , i feel bloated , tired , sluggish and mentaly slow for about 10 hours and then start to feel ok again , i find eating a low carb meal for my omad i dont get any of that , i am particualy sensitive to carbs , not everyone is the same and like i said you will see some people do fine on omad with carbs and have steady weight loss .
