OMAD - One Meal A Day diet.

Hi Folks,

Has anyone heard or tried OMAD(One Meal A Day) diet?

Basically, you skip breakie and lunch. Only have a big dinner in the evening. if you google it, looks like it's quite a hot topic at moment. it says, on top of losing weight, there are many other health benefits.

Just would like to hear your guys opinions. If you have tried and are doing it, let us know your feedback.

Many thanks

    I've not heard of that one before, though my doctor did advise not eating for like 16-18 hours, twice a week could help with metabolism a bit. With that said, I've started the Impromy diet and it's actually been working quite well.

    • i skip lunch on weekends and i can feel the burn … & discomfort

      gastric ?

    intermediate fasting. Eat twice a day, 10am and 4pm, so you have 18 hours of fasting in between.

    focus on discipline rather than diet fads

    staving yourself isn’t going to make you skinny

        A diet of rice and walking 5km each way for fresh water would make anyone skinny.

    • +6

      staving yourself will definitely make you skinny. but healthy or not is another question…

    Give up sugar.

    • and beer

      • Beer's fine - there's no sugar in beer :)
        Besides, what's the point of living if you can't drink beer lol?

        • makes me fat

        • @MoonlapseVertigo: Maybe it's the quantity? Alcohol is processed by the liver in the same way as sugar (fructose), so too much is not a good thing.

          @headphonejack: yep, that's the one. Can't stop at 1. It's all or nothing haha

          @headphonejack:

          i thought alcohol breaks down into sugar , no ?

        • @phunkydude: Yes all carbohydrates break down into sugar if not burned off as energy

        • @phunkydude: Alcohol (ethanol) is fermented sugar.
          Sugar breaks down into alcohol, not the other way around.

        • @headphonejack: Yes, but sugar ends up as "bad" fat around the guts and organs. Beer ends up as Moobs - unless you overdo it. Then it hides away in the liver…

  • Whats the goal?

    • weight control, be healthy and save time and money…

      • +2

        Why don't you just look at what you eat now, and cut the bad stuff out and replace with good stuff? I can tell you right now if you can't do that, then all sorts of miscellaneous diets won't help you.

        • Exactly right, people focus too much on diet fads rather than eating healthy. I eat 4 times a day but weigh only 60kg. I am always full of energy and never feel tired.

          There is no "best" diet, as everyone is different. However, my personal rule is 60% Veg/Fruit and 40% Meat (White meat/Red meat one for lunch, one for dinner). "Treats" are once every few days or so little that it does not really count (like 1-2% overall).

          Obviously, no soft drink at all. After drinking only water for 2 years, soft drink tastes like shit to me after a sip. Same applies to juice. You can really taste how bad both are after having only water for a long time.

          Now, this is not a diet fad I picked up, I've been raised to eat like this. So for me, it is normal.

    Do you need to lose weight? What is your current diet like - do you eat lots of processed foods or drink lots of alcohol? People love to over complicate food and weight. It is really as simple as eating real food, and not too much of it. Cut out processed crap - eat fresh real food and don't eat too much. No need for fancy diets with fancy names.

    • and combined with moderate exercise.

  • Sounds like a form of intermediate fasting.

  • +1

    Sounds like something Gwyneth Paltrow would try until her bones got brittle. Two meals is fine, but one just means you are metabolising your own muscles. You'd be shirty, too.

  • +1

    It's a fad diet, if you adhere to the rules set out by whatever guru came up with it then you will most likely see some level of benefit but as with most fad diets you'd probably see the same (if not better) results by adhering to a healthy eating and exercise plan.

    It's not a terrible idea but it's badly implemented.

    The food retailing/processing and government have been pushing the idea for decades that eating all the time is healthy when it is no such thing - what it is is profitable because people eat more if they're constantly eating carbohydrates. Humans simply didn't evolve as animals that ate constantly and we were most successful when eating meat which means a feast and famine existence.

    If you restrict eating to 8 consecutive hours of 24 in each day with nothing but water outside those 8 hours any energy that you intake you tend to be made into muscle rather than fat. Starting the day off without breakfast is not the catastrophy that the gummints claims it is, remember: it's profitable.

    The key here is the break with no food - if you consume anything other than water, including coffee, your liver will be activated and the effects of the break will be lost. You can eat exactly the same thing as normal, just do it in an 8 consecutive hour period and don't eat outside those hours.

    You can increase the time period to 10 hours or 12 hours or what is convenient but the effect may be less.

    That nauseating, sick feeling that you may experience when you first begin is this thing called hunger, nothing to worry about, it will stop in a minute.

      "You can eat exactly the same thing as normal, just do it in an 8 consecutive hour period and don't eat outside those hours."

      So if my normal diet consists of non stop chocolate and deep fried foods, I will be skinny as long as I eat the same amount of food I do now but squeeze it into an 8 hour period? This doesn't sound right to me. Regardless of which hours of the day I am eating at my calorie intake would be much higher than my energy output and I would still be piling on the weight.

      Energy balance should be the goal, not focusing on watching the clock.

  • +2

    Hmm doesn't make sense? Wouldn't you have your large meal in the morning so you have energy for the rest of the day? As opposed to a large meal at dinner time when you don't need much energy so a lot of it goes to fat?

    • I don't agree with you. the whole idea of this diet is to let your body to access your energy store (fat). If you dont't eat during the day, it doesn't mean you are really lack of energy. as long as you have body fat, your body is able to find energy. it says you will feel hungry at the beginning because your body is used to three meals a day for so long, you will gradually get used to it, and won't feel hungry.

        Yeah fair enough, I don't have a weight/fat problem so I was thinking in terms of general health benefits. Intermittent fasting or having liquid-only days is great for the body too.

  • +2

    It works well - the weight loss Is quite steady.

    The only issue I have is if I don't eat at lunch time, I don't feel like I've had a lunch break for work. So sometimes I eat for the sake of eating, which is bad. Skipping breakfast is easy though.

    Read up on insuline and its effects.

    Read up on insuline spikes.

  • Work all day & you can only have one meal, sounds like slavery to me

  • +1

    Probably not great to have your only meal at dinner time - might be better to have your one meal at lunch time and then burn those calories throughout the day as you need them. I've done this sort of fasting and though it gives good short term results, it doesn't work long term for most people.

  • I wish it was that easy to lose weight.

    I rarely have breakfast (don't feel like eating early in the morning) and often skip lunch (busy at work).

    I am still fat (I need to eat healthier and exercise more).

    I think the OMAD would only work by limiting kj - if you still have the same kj (or near enough) but in one meal then you'll just end up like me.

    I order to lose weight I need to eat less than 5000 kj a day and exercise and then it's still a very slow process.

  • Exercise (getting fit and healthy) is a better way to lose weight than starving yourself all day and then gorging on a meal later. That meal will most likely turn out unhealthy as no one wants to starve all day and then come home to a salad.

  • I do this but only I try to squeeze as much out as I can in a day and do some crazy stuff in real life and virtual life for the sake of efficiency and increased productivity.

    Maybe I should not recommend but yeah I like to do the whole binge thing in real life and it has passed on in other aspects of my life like stocking up on stuff all in one go. Time will tell if it is good or not for my health but it fits my lifestyle and honestly I would love to eat regularly small meals a day but for me that would be a luxury aka more time spent on eating and relaxing with food which I love and like but less time on everything else.

    I made this decision a long time ago and still alive today haha lol.

    Basically if you are fine with winging it a lot in life and doing odd stuff this may be something for you but everybody is different and not all lifestyles are the same.

  • Would not work for me, but would work for some. People are different.

    I could not function during the day if I hadn't eaten. All I would do was think about food.

  • All diets do not work unless you change your eating and exercise behaviour permanently. If you do diet you will put it all back on again plus more when you stop.

  • I highly recommend reading 'The Obesity Code' by Jason Fung. Goes into details about how the body processes food types, and how they effect metabolism and insulin production and body weight. Lots of interesting information to help guide someone keen on making dietary changes

  • Great way to end up with bowl cancer and to INCREASE your weight!

  • Only eating at night is totally crazy … and especially if meat is involved.

    Your body clock is designed to rest from digesting food in the evening and overnight.

    There is a lot of research evidence to support no food after 7pm (8 in some papers).

    Meat in particular takes hours to leave the stomach.

    For many years I ate only between about 12 noon to 8 pm every single day.

    For the last 4 or 5 months though, this is not working for me. My stomach just cannot handle it. It actually isn’t handling food well at all.

    I have complex health and digestive issues, but I lost 27 kg with this pattern- when speciialists thought I would not lose any. I felt much better.

    It sounds like an excuse, but I have a metabolic disorder and my body stores fat but will not burn it. So their concern is I lost muscle (broken down for energy).

  • I've been intermittent fasting for 6+ years with good results.

    I follow James Clear's The Beginner’s Guide to Intermittent Fasting, it also covers the "Isn't brekky the most important meal?" question.

    Note that it's NOT a diet: you still eat the same food but in a smaller "feed" window, increasing your "fasted" state.

    Benefits:

    • Easier than most diets = higher compliance / greater chance of success.
    • Adjustable to you, e.g., 12-8 PM may fit your social activities better, or 8 AM - 4 PM, or… experiment.
    • Significant (well-researched) physiological benefits as with most fasting routines, including longevity.

    If a goal is to burn fat for fuel, one thing highly complementary to fasting is increasing your intake of good fats, e.g., nuts, avocado, and decreasing some carbs, especially the highly refined stuff.

  • Maybe check out Dr. Michael Mosley's BBC doco Eat, Fast and Live Longer (also on Vimeo).

    He's genetically predisposed to several chronic diseases that men in his family have succumbed to.

    From the first 30s:

    • I am medically trained, I know all the standard advice for staying healthy, but in my case it doesn't seem to be working.
    • I wanted to see if science can offer a different way to stop the rot, slow the clock.

    Spoiler [56:30 mark]: The results have been absolutely fantastic for me (but it doesn't mean intermittent fasting will work for everyone).

    Nothing wrong with one meal a day, but not too late as others say.

    I generally need to eat something small at some point, but 2 pieces of fruit during the day, then early dinner works for me.
