At 2pm on a Friday, my body has been negotiating with my brain for about seven hours.
The first ask comes around 9am — subtle, easy to ignore. By noon it has gotten louder, draped in reasons: you trained this morning, you have a long afternoon, one meal early won't matter. By 2pm it has stopped pretending and is simply presenting the case for surrender in the clearest possible terms.
I eat at 6pm. One meal. Every Friday. This is OMAD — One Meal a Day — and it is the clearest practice in my week. Not the hardest. The clearest.
I did not start this because I read a study. I started because I wanted to understand the difference between hunger and habit. Those two words sound different but feel identical in the moment, which is the problem. The body does not signal "this is habit asking" or "this is genuine need." It signals hunger. Uniformly. Urgently. Without useful metadata.
The only way I found to learn the difference was to say no to the signal for long enough to watch what happened next.
What happened was: nothing urgent. The signal peaked. Then it receded. Then it came back, slightly different — more like background noise than alarm. And somewhere in that recession I understood that most of what I had called hunger for most of my life was something else. Habit. Boredom. Anxiety looking for a task. The body reaching for something familiar because familiar is what it does when it is not directed.
The feeling I had always treated as instruction was mostly just weather.
That was a surprising thing to learn at 50-something. That the feeling I had always treated as instruction was mostly just weather.
The meal I eventually eat on Fridays is not a reward. I want to be precise about this because reward framing is where most fasting conversations go wrong. The meal is not what I was waiting for. The waiting was what I was there for.
What I eat on a typical Friday OMAD: something clean, something satisfying, something I made rather than ordered. Eggs, sometimes. A good piece of protein with vegetables. Whatever is in the refrigerator that qualifies as real. I do not eat a feast. I eat a meal. The difference between those two things is significant: a feast is compensation, and a meal is just a meal.
I eat slowly. I am not hungry in the frantic way the mid-afternoon body predicted. I am hungry in the honest way — present, aware, without theater. The food tastes more like itself than it does on other days. Then it is done. And the week ends.
The urgency of a feeling is not evidence of its validity. And the quality of the decision improves significantly when made from the other side of that feeling rather than inside it.
Here is what OMAD Friday actually teaches, which took me a few months to see clearly: it teaches that the present moment is almost never as urgent as it insists.
I use this knowledge constantly. In meetings where someone is creating pressure that the moment does not actually warrant. In decisions where the timeline being proposed is driven by anxiety rather than requirement. In conversations where the impulse to respond immediately is the impulse I most need to wait out.
The pattern is the same: something arrives with urgency, presenting itself as needing immediate action. And the practiced response is: let me see if that's true. Usually it is not. Usually the urgency is a feeling, not a fact.
I learned that in the kitchen. Between 9am and 6pm on a Friday.
I am not recommending this to you. That is not what this is.
What I am saying is that every discipline I have found worth keeping has taught me something that lives far outside its original domain. Running teaches you about pacing. Strength training teaches you about patience with progress. Keto teaches you that most of what the body calls necessity is preference.
Every discipline worth keeping has taught me something that lives far outside its original domain. OMAD teaches you that clarity tends to live on the other side of the thing you were about to reach for.
And OMAD every Friday teaches you that you can tolerate much more discomfort than you think you can — that the urgency of a feeling is not evidence of its validity, and that clarity tends to live on the other side of the thing you were about to reach for.
That is a leadership lesson. That is a life lesson. It happens to also be a meal.
ETL Takeaway
For me, Friday OMAD is not about eating less. It is about practicing the pause — with food, with discomfort, with pressure, and with the small impulses that try to lead the day before I do.
This is not a scientific case for OMAD. It is one person's account of what a weekly fasting practice revealed over time — about hunger, about the body's tendency to dramatize, and about the relationship between tolerating physical discomfort and the kind of steadiness that professional life actually requires. The metabolic science around extended fasting is real: ghrelin waves typically subside within 20–30 minutes without food, and hunger frequency often decreases as the body adapts. Whether any of that applies to your context is something this article cannot know. What I'm confident about is the less dramatic claim: doing one uncomfortable thing consistently, on purpose, changes how you handle everything else.
Disclaimer
This reflects my personal experience with intermittent fasting and OMAD. It is not medical advice. Extended fasting is not appropriate for everyone — particularly those with diabetes, a history of disordered eating, hormonal conditions, or who take medications requiring food. Please consult a qualified healthcare professional before changing any fasting or nutrition routine.
What I'd Actually Do
- Don't start with OMAD. Start with one 16-hour fast per week and hold that for a month before extending the window.
- When the hunger signal arrives, note the time. If you wait 20 minutes without feeding it, notice what happens next. That observation is the whole practice.
- Keep electrolytes available — a significant portion of early fast hunger is low sodium or dehydration presenting as food craving.
- Track mental state mid-fast, not just physical sensations. The clarity some people experience by early afternoon on an empty stomach is one of the most reliable signals the practice is working for you.
- Apply the patience transfer: the next time something arrives at work with manufactured urgency, ask the same question you practice on Fridays — is this a feeling or a fact?
- Talk to a clinician before extended fasting if you have diabetes, disordered eating history, hormonal conditions, or take medications that require food — this is a practice that needs real context, not just inspiration.
