What I Learned From Eating One Meal a Day For 28 Days

What I Learned From Eating One Meal a Day For 28 Days

From the beginning of April 2019, I’ve been experimenting with eating just one meal a day, also known as the OMAD diet.

I stumbled across the OMAD diet a few years ago after researching optimum vegan diets that increase longevity and weight loss.

After getting lost in a YouTube session, I came across this vegan strongman who appeared to be living in the middle of nowhere committed to powerlifting and eating one sizeable plant-based meal each day.

I was inspired to try OMAD, but like many of us, I procrastinated to prioritise my health because I had too much work on at the time.

But after quitting my full-time job to go all-in on The Minimalist Vegan, I found myself with more bandwidth to focus on my health.

In addition to eating one meal a day, I started doing light resistance exercise, increased my average sleep and started a regular practice of stretching. I’m no longer running on adrenals and feel more rested and relaxed.

It’s amazing what lightening your load on commitments can do to for your health!

Note: this post was updated on September 2nd, 2019.

But out of all of the new healthy habits, OMAD was the most impactful by far. And in this post, I’m going to share what I’ve learned through my month-long experiment.

Specifically, I’m going to share:

  • A brief explanation of the OMAD diet
  • The time of the day I eat my one meal
  • My challenges with drinks (i.e. coffee)
  • The benefits I’ve found since starting OMAD
  • Things I’ll change if I choose to continue this way of eating
  • My OMAD update

Quick caveat: I’m by no means a health professional, and I did not seek any medical advice before starting my OMAD diet. I’m purely sharing my experience with you to give you real insight and feedback from what it’s like to eat one meal a day. If you want to try out the OMAD diet, I suggest you seek advice or at least do your own research.

With that out of the way, let’s get into it.

What is the OMAD diet?

Eating one meal a day is a form of intermittent fasting or time-restricted eating. Intermittent fasting is usually when you would eat in an 8-hour window, say 12 pm to 8 pm and fast for the other 16 hours (including sleep). People in the know of this approach would refer to the split as the 16:8 fast.

OMAD takes intermittent fasting to another level with your eating window decreased to 1 hour, leaving you with 23 hours to fast. This is a 23:1 ratio.

When is the best time of the day to eat your one meal a day?

From what I’ve read online, it’s common for folks on an OMAD diet to eat in the evenings. I couldn’t find any specific reason as to why evenings became the recommended time window.

During my experiment, I chose to eat my one meal sometime between 12 pm and 2 pm. There was no science behind my decision; it just felt right.

Having said that, though, when you eat just one meal a day, you are tasked to consume a significant amount of food in a short amount of time. So for those of us who get tired after lunch, because your body is busy digesting food, this feeling is undoubtedly amplified when you’re eating a supersized meal.

I have the benefit of working from home and can control my hours. So after lunch, I tend to rest for a while before getting back into work.

For this reason, I can understand why it might make more sense to have your eating window in the evenings, to sustain more energy during the day, and avoid the afternoon crash.

What can you drink on an OMAD diet?

With any intermittent fasting, it’s vital to ensure you’re adequately hydrated. So for sure, during my OMAD experiment, I drank more water than usual. I couldn’t tell you how many litres on average, but I always like to ensure that I’m adequately hydrated, which you can test by the clarity of your urine.

But outside of water, I did drink coffee and tea. Now, most intermittent fasting guides will advise that you can only consume calorie-free drinks when fasting. So this would include black coffee and herbal tea.

Upon further research, I found that some health experts suggest that these drinks are not advisable to consume during a fast as coffee and tea contain xenobiotics which needs to be processed by your liver or gut.

Okay, I must admit that I did have coffee and tea with either nut or soy milk, about 50% of the month.

So if I were a purist, I wasn’t technically fasting by the book. This is my next challenge, which I will discuss later in this post.

What are the benefits of eating one meal a day?

 

Weight loss

It’s been widely reported that intermittent fasting is an effective method for weight loss. And it makes sense. You lose weight by creating a calorie deficit, e.g. calories burned to exceed calories consumed.

It’s unlikely that you’ll be able to eat a full day worth of meals in just one sitting; therefore you’ll naturally be consuming fewer calories than you usually would—giving you a better chance to achieve a deficit.

I’ve written about the challenge of being an overweight vegan, and I’d be lying if I wasn’t curious to see if the OMAD diet would have any impact on my weight.

At the time of publishing this article, I’ve participated in OMAD for 28 days. And in that time I’ve lost 4.3kgs (9.4lbs). It’s not groundbreaking, but it is encouraging considering I haven’t been eating like an angel (more on that later).

Save money

What does it cost you to eat breakfast, lunch, dinner and snacks every day? Now reduce that cost by roughly 70%, and that’s how much you’ll be saving by eating one meal a day.

Eating all day is expensive, and it becomes apparent when you see the results in your bank account. You buy fewer ingredients and eat out less. This is an underrated benefit of the OMAD diet.

Save time

Another excellent benefit of OMAD is the time you save, not thinking about food. Now in the first three days, all I could think about was food. But once I got past that, it felt like I freed up a few extra hours each day to get on with life.

Just thinking about how much time is spent planning, preparing, travelling to consume food each day. It blows my mind how much time food takes up in our lives.

I know Maša was sometimes envious of me in situations where she’d be scratching her head about what to eat for dinner, and I was off doing my own thing.

Discipline

If you’re interested in challenging your willpower and improving your self-discipline, eating one meal a day will provide for some good practice.

I love testing my comfort zone, and this last month has made me uncomfortable at times. But like all painful situations, when you overcome it, it improves your self-confidence and mental toughness.

What I Learned From Eating One Meal a Day For 28 Days

What are the challenges of eating one meal a day?

 

Getting through the first three days

As I mentioned above, getting through the first couple of days on the OMAD diet was hard for me. I experienced intense hunger pains and loss of energy in the evenings (I was crashing at 8:30 pm, which was unusually early for me).

But once I got over that three-day hump, my body started to adjust as I settled into a new routine.

Navigating social situations

I loved challenging myself to bring a positive attitude in social environments where I wasn’t eating due to my OMAD commitment.

However, I did feel that friends and family felt uncomfortable at times because I wasn’t participating in a shared meal.

I remember on Maša’s birthday, we went out to dinner with her family, and I happily sipped on water for a couple of hours while the gang ploughed through a three-course meal.

But for the most part, people are understanding, and it often becomes a point of conversation. Furthermore, I’ve been vegan for five years, so people in my life have lots of practice with me doing different things at the dinner table.

Getting enough nutrients

With one meal a day, there’s less opportunity to ensure you get enough nutrients.

Also, I’ve read that people eating an OMAD diet can feel entitled, or deserving of food once they get to their eating session. This kind of mentality can lead to overeating or binge eating unhealthy food.

I can certainly relate to this feeling of entitlement. My internal dialogue would say things like, “I’ve waited 24 hours for this meal, I should be able to eat what I want”. It’s easy to get caught in this mindset as your meal becomes an event.

If you’re not careful, you may end up overeating junk food, and thus creating a calorie surplus.

Is eating one meal a day sustainable?

After eating OMAD for a month, I easily feel like it can become part of my lifestyle—or at least something that I do on and off for the rest of my life.

I love the benefits of saving time and money while keeping my weight down. But if I decide to keep it going I’d make a few tweaks;

  1. Remove tea and coffee entirely in fasting hours, and stick to water.
  2. Drink one cold-pressed juice to start my meal, followed by a large buddha bowl for a variety of nutrients. Also, juices and bowls have many variations, so I can keep things interesting.
  3. I would consider tracking my calories to see the quality and diversity of nutrients I’m consuming.

Japanese Inspired Bowl

Now I can confidently make claims to these adjustments because I’ve already established a habit of eating one meal a day. The hard part is done. It’s now time to refine and optimise for better health and performance.

Anyway, that’s my experience of eating one meal a day. I’m keen to explore this lifestyle in more detail and greater commitment to healthier foods.

My OMAD update

As I write this update, I continued eating one meal a day for three months in total. The last time I checked my weight, I had lost 8 kgs (17.6 pounds). 

I addition to OMAD, I was consistent in exercising at home for 7 minutes a day, using this app. I felt incredible with these two new habits, and my body was transforming. But with demanding work commitments, I, unfortunately, got unwell, which forced me to break my streak.

I’m an all or nothing type of person, so I tend to beat myself up when I break promises to myself. I pushed through with OMAD but had a cheat day here and there.

I continue to follow OMAD today. However, I do have days where I might snack on some food in the evenings, or eat out occasionally with my wife. 

I haven’t recorded my weight since my last weigh-in, but I feel and look the same. More importantly, I’m not so hard on myself, and I still eat far fewer calories than I was before I started eating one meal a day.

    This is so inspiring and candid. Thank you for sharing your experience. I recently switched from three meals to two meals, and I have been wondering about dropping down to one… Your experience has given me the courage to try it. I’m going to try it for May, starting today. Thank you!

    • Hi Charity, I’m glad this post has inspired you to take it a step further and go down to one meal. I’d be interested to see how you feel after doing it for a month. Good luck!

  • Kelsey 03/05/2019 Reply

    Wow interesting, I’d not heard of this before and after reading this I’ve seen it pop up more. I think it’s an interesting concept, one I may apply to myself in future. I am an overweight vegan because lotus spread is life haha, jk I’ve just always been overweight. In all seriousness though I think I will drop a meal and then maybe move onto this after a few weeks to see if it works for me! I’d love an update when and if you have more to share. Thanks 🙂

    • Love it, Kelsey! Experimentation is the only way to know how your body will respond. Sure thing. I’ll see if I have more to share after another decent period of time 🙂

  • Nicola 06/05/2019 Reply

    I started yesterday and I have done different IF over a few months. I started doing the 5:2 for a while mid-last year or something and recently I have tried the 20:4 but I found that makes me really hungry, and I do an OMAD day every so often. Now that I know I can do it pretty well I’m planning to do it for 15 days, as I am a young female women and we are advised to be very careful with IF we are usually told to stick with the 5:2 or 16:8 but I’m going to see how my body responds for me. When I did the 5 days it actually made me feel a whole lot better hormonal which is the usual concern so I’m just going to try 15 days and if I can do it with no negative health impacts that’s great, if not then I’ll just stick to short amounts of time that my body can do safely. Great post I enjoyed reading it. 🙂

    • Hi Nicola, so glad you enjoyed reading my post. It sounds like you’ve done quite a bit of experimenting yourself! You’re so right. You got to listen to your body and see how it responds to different types of IF. Let us know how you got with the 15 days.

  • Tracy Crawford 30/05/2019 Reply

    Hi, Michael. I’m a 47 year old, mostly raw vegan and about 50 lbs overweight. My caloric requirement is around 2200 calories by the older, conventional models. Problem is that 2200 cals is ALOT of food to consume on OMAD. Would you share my opinion that I should simply pack in as many nutrient dense calories as comfortably possible and worry about totals later? My concept is that my body will tell me if I’m lacking as I go along. I may be wrong but my belief is that 1000 raw, plant based calories are equivalent to 2000 meat and oil inclusive calories. Am I close here?
    Thanks so much,
    Tracy

    • Hi Tracy, kudos to you for eating mostly raw. Very impressive!
      I’ve wondered the same thing about cramming required daily calories into OMAD—but ultimately, I decided to throw tracking out the door and respond to how my body is feeling. I’ve found that eating your caloric intake is incredibly hard to achieve and in a one-hour sitting, so I don’t force it. This is a personal decision and perhaps a plant-based nutritionist would have other ideas?

    • Bjork tagneros 01/07/2019 Reply

      A calorie is a calorie, doesnt matter what it comes from. So eating 1000 calories of one thing can not equal 2000. Calories is measure of energy.

  • Chris H. 12/06/2019 Reply

    Hey Michael, great article! I’ve been doing OMAD for a little over a year now – down 80 pounds with about 40 left to go. In my experience, it’s the easiest method of weight control for all the reasons you set out in your article: naturally less caloric intake, less insulin spikes throughout the day, and puts the body into a background “can’t rest, time to find food” mode that paradoxically increases energy. At this point it’s the natural rhythm for my body and (aside from the social aspects you mentioned) an easy routine to stick to.

    I personally start my day with black coffee because it’s my vice! And I drink about a gallon of water throughout the day to stay hydrated. Will note here that with reduced water consumption through food it’s important to stay hydrated but also not to go too overboard because also reduced electrolytes and don’t want to induce hyponutremia. My meal is around 6 PM. I am not vegan, but try to incorporate 8 different fruits and vegetables into every meal as a guide, then a light animal protein of some sort to balance macro and micro nutrients.

    Again, great article and best of luck!

    • Hi Chris, your story is so inspiring, and I was hoping to find examples like yours to feed off!
      It’s incredible that you’ve made it past 12 months on OMAD. But now that I’m over two months in, it kind of feels like I could easily keep it going.
      I also love your simple meal goals of 8 different fruits and vegetables. Thanks for sharing, I’m sure readers, like myself, will find your experience helpful.

  • Dora G. 19/06/2019 Reply

    Wow! What an interesting article! Thanks for this, I am seriously looking into OMAD as I am 2 years vegan and hoping to lose some weight. One questions is I’m searching for the one perfect vitamin and nutrient meal for the day as a vegan…. any suggestions? Also did you take any supplements in the 29 days ?
    Thanks, you are a true inspiration ?

    • Hi Dora, I’m glad you found this post interesting! I’m not sure I’ve found the one perfectly balanced meal for OMAD, but as I mentioned in the post, it’s hard to beat the combination of a green juice and a huge Buddha bowl to pack in your nutrients. I’m historically bad at remembering to take supplements, so no. Now and then my wife will remind me to take B12, but that rarely happens.

  • Anna 21/06/2019 Reply

    so inspiring and great to read, i have started OMAD diet 7 days ago am into my 8th day today, my struggle is cutting off sugar and carbs and it is a bit challenging but am keeping focused and i want to make it a life style and have one day a month or so to go out with family and friends and eat with them a healthy meal that way friends will be comfortable and happy,
    i have a question i feel like in the evening i eat one meal but unsure if it’s a big meal or normal meal as i try to eat for 15 mins max so i have natural yoghurt and lettuce cups filled with lean beef mince and veggies followed by a full tablespoon of crunchy almond butter and one piece of fruit mainly passionfruit and pistachios is that too much food?
    i can’t see any difference in my appearance as yet as i know things take a while to show up physically.

    • Hi Anna, I’m so glad that you found my story inspiring.

      Wow, well done for making it past one week on OMAD! I also love the idea of having one day each month when you go out with friends and family.

      It’s hard to say what is enough food based on your body’s needs. If you’re unsure, I’d recommend tracking your calories in an app like chronometer.

      Regarding progress, I’ve been OMAD for nearly three months now, and my weight loss has been VERY gradual. I do eat quite a bit more food than you, but I assume I’m also a different build.

      Just stick with it, and limit yourself to checking your weight monthly. This is at least what worked for me.

  • Steve 27/06/2019 Reply

    For me the best way to lose weight is OMAD every other day with nothing in between (like 47:1 fasting). It is very easy to lose weight this way and it lets you be insanely focused. This should also be combined with 4-5 hours of sleep every day for maximum effect, the 4-5 hours ensures that you have more time in the day.

    • Wow, Steve, I can’t say I’ve heard of this before. It sounds intense, and I have no doubt it would be an effective way to lose weight and free up time. I just don’t know how sustainable that would be for me. Thanks for sharing.

    i enjoyed reading this article, so interesting! As for me, I did the 16:8 diet for about 2-3 months and it was hard in the beginning because i was always home and wanted to eat. However, now that I have a job, I only eat once per day and I already lost 2 lbs in just one week! which is crazy because i could not lose weight when i was doing the 16:8 diet. But I have to say that I do get really tired and just like you said I want to sleep at 8:30, which is very very surprising for me. Thank you for sharing your experience!

    • Hi Diana, thank you for sharing your experience with us. What a difference it made dropping one meal. I’ve now been on OMAD for over three months, and I’m no longer feel tired. It’s amazing how your body adapts.

  • Brendz 21/07/2019 Reply

    Hello Michael,

    I felt inspired after reading your article. I think I will try OMAD very soon. I have been doing 16:8 for 2 months now with very minimal results because I have done it the wrong way. I use the 16:8 as a spring board to OMAD. I am so excited.

    Thank you very much for sharing your experience and more power to you.

    Sincerely,

    Brendz

    • Hi Brendz!
      You’re pretty much there coming from 16:8.
      Keep listening to your body, and I’m sure you will get the results you’re after.
      Thanks for sharing!
      Michael

    I love this article. I have wanted to try OMAD for so long but I felt that the info online was gimmicky or varied too much. Your experience was realistic and honest. Thank you so much. I waiver between vegan and vegetarian…one day I’ll get it right 🙂 Looking forward to trying OMAD now 🙂

    • I’m glad you found this article to be honest and realistic! Hope you feel good after trying OMAD 🙂

  • Dom 29/07/2019 Reply

    Thank you for this! I was looking for a personal perspective after hearing about OMAD and yours was by far the most helpful.
    I’ve been doing 16:8 for about six months and have even had a few days with just one meal. I’m also not eating carbs for the most part. I’ve lost about 50 pounds so I’m a big fan of intermittent fasting but I still feel pretty hungry in the mornings and at night if I’m up late. I can tolerate it and it’s only really bad if I’ve cheated and had carbs or sugar recently.
    I’m most interested in seeing how cutting down to one meal a day affects my hunger pangs and what it’s like long term.

    I’m a happy, fat, diabetic, old carnivore! This is a good article. Thanks. I’ve been eating One Meal a Day for about 3 weeks now and so far I’m loving it. I’d been having considerable trouble keeping my blood sugar levels within recommended thresholds (always too high). The many small meals a day recommended by all the diabetes organizations wasn’t working, despite doubling my meds. So I tried a keto approach for a couple of weeks and my sugar went down immediately. But I didn’t like keto. I’m kind of skeptical of any approach to eating that cuts out huge categories of food types. Then I met a guy who had lost 100 lbs on OMAD and gone from being Type 2 Diabetic to ‘normal’. It was enough to cause me to give it a whirl. And I’m loving it. And my body is loving it. My blood sugar is consistently in range (I never seem to have trouble with low blood sugar ratings; always when they’re off they’re too high). I was concerned about that because the popular wisdom is that regular small meals is the way to manage blood sugar.

    So far I haven’t seen any dramatic weight loss but I’m not someone who has access to a set of scales. But even if I lose no weight I’m a very happy old gal!! I love how the conversation inside my head about food has shifted. On keto and in general it was a deprivation conversation. “Gee, I’d love to have some of that but I can’t because I have to keep my blood sugar in line.” Now it’s “OK, you want that? Great. Just wait x hours and you can not only have it but have as much as you want of it.” Often by the time my meal time comes around that urge has moved on, btw. So far the only real challenge I’m having is ensuring that I get enough fruits and vegetables in in one hour. One trick I’m using is that if I’m especially low, I make up a shake with 3-4 servings of fruit in it and have that as my dessert. I make a small pot of French Press coffee each morning and have my couple of cups of that and the rest of the time it’s water and water flavoured by letting herbal tea bags sit in it for 30 min. I seldom feel hungry. And when I do that “It’s OK. Just X hours til you can eat what you want” conversation kicks in and I relax into it.
    I’m about to have my regular round of bloodwork done so it’ll be interesting to see if my cholesterol is up. I’m medicated for that at the moment so that’ll be an interesting variable. And it’ll be a test of my doctor/patient relationship when we have the conversation about my eating choices. He’s a fairly new family doc I have so I’m not sure how open to innovative thinking he is.
    Overall, though, it sure seems to be working for me. I feel good. I love my meals. I appreciate the shift in my thought patterns. And I’m over the moon that my blood sugar levels finally seem to be in range on a long term basis!

    Not bad for a 71 year old, meat eating, food loving, fat (and hopefully soon to be non-diabetic) gal!

    I see some say the best time is to eat in the evenings. How long of a window should you wait to go to sleep? Always heard eating and than going to sleep is not good. Thanks !

    I’m considered skinny fat and have bad allergies to dairy proteins and gluten. And I don’t eat citrus (lemon, apple, oranges) because it weakens teeth/gums. Don’t have diabetes or sugar issues, but do get the shakes after having carbs at breakfast or lunch, but not dinner. I recently OMAD only on weekdays at 6-7 pm. On weekends I eat light breakfast, lunch, dinner with the family. I like OMAD a lot. I feel it’s not about losing weight, but getting back to our biological shape. I don’t think humans were meant to be shaped like a tea-pot or wooden spoon.

    Takes about 3 consecutive days of OMAD with to go keto. My body started toning up without exercise. I was afraid to add any kind of exercise. After the 3 days, no heavy breathing, increased focus, energy, reflexes & memory. Have a lot less anxiety, less grumpy or tired after work. I don’t mind fixing/cleaning stuff around in/around the house. Like to play with my kid. Eye’s feel healthier, more clean/white and less sensitive to bright light. Feel lighter. Don’t have motion sickness anymore (can eat food in plane & boats). No bloated feeling. If I do consume some dairy/gluten, don’t have as bad of a reaction, which then heals a lot quicker. I have a physical job, heavy lifting with 8 miles of walking. OMAD still works. Have lots of focus and energy.
    2 or 3 vegan meals per day messed up my thyroid, felt like I swallowed a marble. With Vegan OMAD, I don’t seem to have that issue. I think vegan meals are too potent for 2+ meals.

    • Hi Ak, thank you for sharing your OMAD experience with us. It looks like you’ve found a right balance with weekdays and weekend splits. I agree that OMAD is getting back to our biological shape. Eating multiple meals seems excessive when you think about it.

  • Toni 20/08/2019 Reply

    I have been doing the OMAD diet since 7/5/2019, and have lost 11 pounds so far. I am menopausal and all I was doing was gaining weight. I got up to 190 and my mom told me to try eating one meal a day. When she told me about it I thought it was impossible. I have tried everything under the sun and couldn’t loose weight, so I thought I would give it a try. I love it. I’m loosing weight, I stopped taking my hormone pill, I still have energy, No hot flashes, night sweats, brain fog, mood swings etc…. I am elated…..I know this sounds unbelievable, and it is, but true. I have done my research about the OMAD diet and it’s really legit, and I feel great. I eat one meal a day, and I eat whatever I want to eat. I use to think I could just eat how ever much I wanted to eat, but that’s not so, because I get full quick, and if I do overeat I am miserable as ever. Which is a good thing because my stomach has shrunk. After reading this blog I’m going to start watching what I eat now. I drink coffee, but I can’t drink it black, so I still add heavy whipping cream and equal. I drink so much water, but I add a little cranberry juice to that for a little flavor. Does anybody have any suggestions for my coffee and water. The only added sugar I use is the equal , and I eat between 6-7 on the weekdays, since I don’t get home from work until then, and 4-6 on weekends. Thank you for sharing your experience.

    • Hi Toni, your story is inspiring. Thank you for sharing it with us! I still haven’t cracked the code on coffee. I’ve had varying success with herbal teas, but it’s just not the same.

    What a fantastic article! Thank you for the inspiration! I’ve been working towards OMAD all summer. I’ve been consistent for about a month. Over this summer I’ve lost 25lbs. I try to eat whole nutrient dense foods when I eat at around 6 pm -7 pm. I also take a multivitamin to be sure I’m getting the vitamins I need. I haven’t cut out my coffee with half and half though. I also drink a slash Simply Light lemonade with mostly water to stay hydrated throughout the day. I’ve found I have more energy eating this way. It’s also easier to just make one meal a day and shop. Tonight I had sardines, cottage cheese, a whole tomato from the garden and a nectarine. I feel full and ready for tomorrow. I make sure I sleep 9 hours a night and I’ve cut out drinking any alcohol. Tomorrow I’m starting strength training. A half hour a day, three days a week. In the fall, when it cools down, I’ll resume my walking routine (2 miles, 5 days a week). I also have mostly stopped dinning out. My brother was in town a couple weeks ago so we went out for fish tacos (grilled fish). I thought that was pretty healthy. A friend came to town for a visit last week. We usually go out for Indian food once a week. I just explained that I’m only eating one meal a day and she was kind enough to bring over some guava and dragon fruit for me to eat at dinner. She was very supportive. I want to loose 40 more pounds by my 50th birthday in May. That would make me very thin, but still healthy. I’ve been thin most my life and it feels good. I’ll let you know how it goes. ~Cheers!!!

    • Wow, Kim! What incredible results! But it’s not surprising as you are very committed to the OMAD lifestyle. Yes, please come back and give us an update on your progress leading up to your 50th birthday. Well done.

    thanks for sharing your omad experience. Although i have been eating with one principal meal a day for d last 25 yrs, Now im trying to improve it. Im keeping my eating-window at 3-5am, and eat a fruit or some salad during d day. so its no longer strict omad.

    • 25 yrs! It’s nice to see an example of longevity with OMAD. Thanks for sharing your experience with us, Eric.

    im not a vegan. i eat almost everything edible. lately im checking which should be the best omad eating-window.

    • It might be worth tweaking to see if plant-based feels good. The eating window is very personal, based on your lifestyle. Let us know how you go.

    So, I think I’m a bit like you ‘100% in or 100% out. A friend had just started IF and I saw great results in him. I’m overweight and I needed to make many changes , especially with mindset. I have taken on the OMAD and I’m eating a Keto diet (so only carbs in low starch veggies and zero fruit). Everything is better. I’m at Day 12 and my sleep has improved so much. Head hits the pillow and I’m asleep, my mood is way happier, I can actually think clearly!! I have more energy. I have lost 4.4kg in 12 days. So that’s like 10pound or something. I was between 170/180 pounds to begin with (76kg) – I only know the metric system 🙂 I am at the gym every day but it’s not high intensity. I eat my meal at night at 7.30pm. I’m excited to see where this leads.

    • Hi Megan! Congrats on making it to day 12 on Keto OMAD. Very impressive. It sounds like you have a solid foundation in place, so I’m sure you’ll go far with it. Just go easy on yourself if you break the chain. You’ve got this! Thanks for sharing your experience with us.

    Hi Michael. Thank you so much for sharing! I started this diet about 2 weeks ago – mainly because i am trying to reverse the symptoms i have as pre-diabetic. I have actually been noticing better blood glucose levels since I started this OMAD diet. When I am hungry i add a pinch of pink salt+cream of tartar (5:1 ratio) to my liquids (cold tea/water/cold coffee) which helps a lot.
    I eat my meal between 12-2pm like yourself and 1 have one cheating day where I eat two meals.
    I am a bit worried about the lack of vitamins (when i eat one meal i day, i try to add one fruit, but sometimes i am just too full after eating). Should I get vitamin pills? Furthermore , I am not sure if working out ealy morning is ok when only having my first meal so many hours later … What’s your take on that?

    • Hi Marlon, that’s so fantastic to hear that you see better blood glucose levels since starting OMAD!
      I understand your dilemma, as it feels like quite a bit of pressure to give your body everything it needs in one meal. Nutrition is not my area of expertise, so I wouldn’t feel comfortable giving you advice. For me personally, I listen to my body. If I wanted to take it further, I would get regular blood test results to measure movement in nutrient levels, and adjust accordingly.

    Interesting post.

    I stumbled onto OMAD after doing it for a week. Have been trying to lose weight for a few years. Tried calorie counting. Worked but made me miserable and snappy. Tried alternate day fasting which also worked but I wasn’t good for much by the end of a fast day. Also overate on feast days. Put all the weight from calorie counting back on. Put about half the fasting weight back, so some of that stuck.

    It occured to me that I could try one meal a day and then after a couple of days I looked it up and it is a thing. Two weeks in and tbh I am loving it.

    Hands down the easiest diet I have tried. I eat at 3pm. Couple of pieces of fruit to start, then soup (with veg!), couple rounds of sandwiches (with veg!), then whatever else I fancy, which is usually very little because by then I am pretty full. Not hungry at all in the evening, in the morning you are only a few hours from eating again!

    Unlike alternate day fasting I never have a whole day to get through. However, alternate day fasting did teach me some useful tips which are making this easier I think.

    1. Drink lots and drink before you get hungry. Like, a pint at a time. Drink early and drink often. You are probably just thirsty if you feel hungry. Sugar free cordial is great for this. Mix up the flavours or you’ll get bored and then you’ll drink less.

    2. Hunger goes away. If you really are hungry, find something to do for 5 mins. You’ll find it goes away.

    3. Fruit and veg in every meal. Ideally the biggest part. You can go a week without meat, junk. Go a week without fruit/veg and you’ll feel terrible. Take vitamin/mineral supplements.

    4. Get busy. Nothing breeds hunger like boredom.

    Hoping this is the diet that works out long term! Funny thing is that I’m making such an effort to ensure I am eating fruit and veg in that one meal a day, I’ve almost given up meat by accident.

    • David, what a valuable share! You’ve got your OMAD system on lock. And it’s really cool that you’re naturally pulled to add more vegetables to your diet. Keep kicking goals and check back in with us later with an update 🙂

    I have been on this particular regiment since late March and since then I have lost a total of 48 lbs. I eat breakfast around 6:30 am. I do cheat probably once a week to eat dinner with my wife but the rest of the week she eats alone and does so with discretion as to not tempt me. The 1st 3 weeks were terrible and it was a taper process but on the 4th week I finally achieved the one meal a day goal. My body is still angry on some days and I get some pretty harsh headaches. When this happens I down about 32oz of water or Lemon water and the ache slowly backs down. It is very important to also make sure you’re supplementing with essential vitamins your body needs since you no longer have the intake from the daily food you once were eating. It took me a several weeks to realize that lack of vitamins and nutrients were causing more harsh side effects than I would’ve liked. A quick trip to the vitamin hut and that was that. The human body is an amazing machine that can adapt and conform to its current circumstances. I encourage anyone who has a weight issue or a health issue to give this a try. The body will go into a state of rebuilding and healing while this regiment is being utilized.
    Good luck and stay strong.
