McDonald’s Serious Lamb Burger Will Fatten You Even Faster Than A Big Mac

McDonald’s Serious Lamb Burger Will Fatten You Even Faster Than A Big Mac

Today McDonald’s starts selling its first ever lamb burger, the creatively-titled Serious Lamb Burger. I’m as keen on the notion of tomato, beetroot, aioli, ketchup, egg and onion as the next burger addict, but be warned: this is quite the kilojoule-packed meal.

The burger costs $7.95 on its own, while a smaller wrap variant is $3.00. But the question we always ask here ate Lifehacker is: what’s the nutritional breakdown? Here’s the data direct from McDonald’s:

  Serious Lamb Burger Serious Lamb Wrap
Energy (kJ) 3370 1460
Protetin (g) 40.6 14.6
Fat, total (g) 41.4 20.5
Fat, saturated (g) 15.2 8.4
Carbohydrate (g) 64.2 25.3
Sugars (g) 11.6 2.2
Dietary fibre (g) 7.3 3.0
Sodium (mg) 1340 393

That makes the Serious Lamb Burger higher in kilojoules than virtually everything else on McDonald’s menu, save for a Double Quarter Pounder (3560 kilojoules).The calorific punch isn’t altogether surprising: lamb is a fattier meat than beef, and the aioli won’t help. The burger also has more than half your daily sodium allowance.

Moderation is the key: there’s no harm in an occasional burger, and I’m all for lamb for a bit of variety. Just don’t eat one every day for a week, and contemplate the wrap as a less laden alternative. As usual, we also advise skipping on the chips and drink. Are you tempted?


      • No one said fat in food = fat in your body. The article clearly states that the burger is the highest calorie item on the McDonalds menu, likely due to the fat content of lamb. Excess calories do equal fat on your body.

        Oh and p.s. On the sugar thing, you know how in the 80’s everyone was scared of fat cos it was evil but it turned out it was just based on bad research and all untrue? Well you are doing the same thing with sugar now

        • Uh no. she’s right. Sugar (added sugar in foods such as every soft drink and lollies etc etc) is something we don’t need at all. yes there is research behind it. it’s one of the biggest reasons why so many people are fat, and have health problems.

          • Completely false. Find me one piece of evidence that shows sugar causing ill effects in non-overweight, non-sedentary people. There isn’t any. All the research shows is that if you take someone who is overweight and sedentary, and give them a ridiculous amount of sugar, they will suffer negative health effects. It is also worth noting that simply exercising with negate most of these effects regardless of sugar intake.

            That’s the thing people need to realise when they look at studies, you can’t just read the conclusion.

            I would really recommend watching this

            Then, since I’m sure that sine you are demonizing sugar you will probably cite Lustig, read this:


            And then scroll through the comments between Alan Aragon (the Author) and Lustig himself, and watch Lustig’s work get completely discredited.

          • I think you forgot to push up your glasses and look around smugly at the end of that, Paul.

          • There are a great number of studies showing how bad high-GI carbs are for you, and how they cause numerous amounts of health problems.

            Also, I agree 100% about Fat. However, this has 15.2g of saturated fat, which is way over the top.

          • No offence Paul but if you read the posts it is Mr Aragon who looks silly. He just rambles on how correlation doesn’t equal causation, correlation doesn’t causation for about ten times. It gets boring after a while.

          • Dude, refined sugar (in almost all foods) has extreme health effects for anyone, regardless of weight.

            One of the major contributors to obesity is white bread, mostly because of all the sugar. When they started adding sugar to bread, people started getting fatter, quicker, because bread is a thing most people eat every day.

            I have this information from someone who is VERY Knowledgeable, also through experience.

        • 1 gram of protein = 4Kcal.
          1 gram of carbohydrate = 4Kcal.
          1 gram of FAT = 8Kcal.

          Excess calories = fat in the body, regardless of the source. Also, the wrong fats (and too many of them) will cause you bigger problems than simply storing excess energy. 40g of protein is pushing it for one meal. 30g per meal is the recommended maximum – any more and your liver & kidneys will struggle to digest it – allowing toxins to enter your blood in the process.

          Nutritionists have been stating for years that the recommended daily intake of sodium should be between 600 and 900mg. Try telling that to the processed food industry.

    • The egg isn’t fake, at least not in the real burger. You have to understand that like most fast-food places, promotional photos are of meticulously arranged products that often aren’t even edible. Their only purpose is to portray the general look of the burger, what’s on it, and to make people want it. For example, in the real Serious Lamb burger, there is little to no chance of seeing the tomato/beetroot from the side. They’re absolutely tiny compared to the bun and patty.

      For anyone interested, we use a oval shaped ring and eggs are freshly cracked and cooked for around one and a half minutes.

  • Get the picture at the top, put it inside a giant burger ring, then hit it with a mallet, and you’ll get a more accurate representation of what you’ll get.

    Still buying one though.

  • If you could only ate two of these a day and nothing else (some additional protein and fibre to get KJ up to around the 8000 mark) then you would be well within the calories and nutritional values to be considered healthy. In reality a burger from McDonalds is not any less healthy than a burger made at home from items purchased from Woolworth’s or Coles. The bad part is do you know anyone that goes to McDonalds and doesn’t order the value meal with the chips and drink. Moderation is the key.

    • Not really.

      If you eat twice per day you’re slowing down your body’s metabolism, which will do nothing for you.

      Look at how atheletes/bodybuilders eat. At least six small/medium sized meals a day, which speeds up your metabolism and makes it process foods in a more efficient way.

  • Maybe they’re not too unhealthy, maybe they are… but they don’t tend to taste very good either way.
    I wonder if they use real lamb in these or switch it around with mutton?

  • tried this today (got it cheaper because i work at maccas and will be learning how to make it myself soon-whoopee ._. ) and the size was a callback to the days when all the other burgers were that big. Its also very, very tasty. I’ll probably wont get order it again for at least for a week though, or maybe even just get it without fries and a soft drink, have it with water instead.

  • One of reasons i don’t eat maccas… Just don’t know what you are eating, cant compare to making a burger at home if you know what you are doing…

    BIG MAC BUN: Wheat Flour, Water, Yeast, Sugar, Vegetable Oil (Canola), Sesame Seed, Iodised Salt, Gluten, Soy Flour, Preservative (282), Emulsifiers (471, 472e, 481), Malt Flour, Mineral Salt (170), Antioxidant (300, 304, 307, 330), Enzyme
    (1100) Vitamin (Thiamin, Folate).

  • First ever lamb burger?. I think not. They’ve had them in India for years. It’s not like they can have Sacred Cow burgers there is it?.

  • #sigh# a word from someone who actually has taken the time to understand nutrition?

    sugar is a simple carbohydrate. Glucose is the simplest (i’m not going into detail on all of them here, if you didnt pay attention in either chemistry or biology, im not gonna bother). Every carbohydrate you consume, from bread to potato to the carbohydrates in that broccoli, will get broken down into glucose before you can burn it as energy. simple sugars are only a problem if you DONT BURN THE ENERGY! simply put, if your sitting around all day, sugar isnt your friend. it also exits quicker as it doesnt take as long to digest, hence sugar crash.

    As for the protein/meat/fat; just because some weasly stick of a nutritionist decides every body shouldnt be eating more than “a deck of cards size portion” of meat, doesnt make it true. As for fat, how many thousands years have humans eaten way more fat than we do today and been healthy? Again, its only a problem if you dont use the energy!!

    A large portion of my diet is protein, followed by fat, followed by carbohydrates. My meals are otherwise balanced and i eat 13,000+ calories a day. Why? Because my job is active and i’m on my feet for 8-12 hours at a time, and without fail practice my martial art or go to the gym EVERY DAY. Think about it; a 6″2′, 90kg guy, with no blood pressure problems, heart problems, cholesterol problems (all tested monthly by blood tests at a sport nutritionist), who can bench press twice his own weight and outrun army cadets (my friends), who eats 13000+ calories a day, mainly meat.


  • Hahahah loving the sugar argument! Did you all know all people are different? So chances are most people can’t agree? So um, there is no point really?

  • lamb burger was over powered by herb/spice content , looking forward to this burger however the lamb flavour was not delivered . I am waiting your next special . loved the sydney stack. clean&simple.

  • Do they have a double-down lamb burger, you kow, like the KFC d-d, only I’d like it with two lamb burger patties, and all the filling inside, no breadbuns.

  • I work at maccas and I read the box where the meat patties come from & yes it is lamb.
    What the other guy said was 100% accurate, if you don’t burn the calories, that’s when you’re gonna have some problems.
    Tried the wrap today & it was actually really nice, only ate a few bites of it cos I was scared of the amount of calories in it (365 calories).
    I do burn off at least 1/3rdof the calories I consume in a day (800-850 calories) by engaging in high intensity activities but still, calories scare me so badly!
    Everything at maccas is pre-made then delivered to us either in a box or a vacuum sealed bag. However it does have all the ingredients listed on the boxes (hence the reason why I know what’s in it).
    Yes we do use Heinz ketchup.

  • TO: Lamb Will Kill Me…

    You can grill (make) your burger to your own liking… (You can take the bread buns off & have two patties instead). Virtually whatever you would like on it, they will most likely deliver however, it will make the cost of your burger vary.

  • Lamb burger is CRAP. Doesnt even taste like lamb, I threw the middle out and just ate the bun.
    dont buy it peeps, especially if you love lamb. What was Kekovich thinking? He cant possibly say it is nice lamb, its F********** HORRIBLE, I dont think it will be around for long..

  • Its friggin Maccas of course it’s fatty. You want to eat healthy, don’t eat junk food. I personally like junk from time to time but it’s not rocket science guys

  • Did anybody see the new “Mary had a little lamb fries and coke” billboard ads by maccas? The Americans are loving the joke at McDonald’s expense cause lamb fries means lamb testicles over there. It’s doing the rounds on the Internet and researchers can’t believe an MNC to overlook this unless they were expecting the Aussies & Kiwis to enjoy the burger with balls! (pun intended – courtesy the mX in Melbourne)

  • I think this ad makes the Mcdonalds staff look unintelligent and nosy. I don’t understand why the young man in the ad cant make the new burger even with a clear diagram in front of him that anyone can understand within seconds of seeing. Not only does he need someone to explain it to him too, but a second nosy employee cant help but butt in to disclose the last 2 ingredients that are bleedingly obvious to all.

    I get the feeling the the ad was not only meant to tell us consumers (shuddering at that word) that they have a new lamb burgder and it would be ‘unaustralian’ not to eat it – but also a recruitment ad for potential new dumb Australians to work in their ultra controlled, no thought work environment that is filled with good looking youthfuls. I dont mean to insult Mcdonalds workers, ive got nothing against the burger or supporting Australian lamb farmers (even though ive heard they will be using the undesirable necks and bellys of UK sheep in their ‘serious lamb patty’), and i concede i may be reading too much into this, but in my opinion this ad does the company’s image & employees no favors & i dislike the brand even.

  • This is actually a massive burger, at least 1.5 time in size of a regular maccas burger, and it’s actually pretty pleasant, if you take out the beetroot and the onions 🙂

  • Whether you hate sugar, fat or the concept of egg on a burger it tastes AMAZING.
    I myself am scared by the sugar content. And Paul, one word for your argument that our irrational fear of sugar is felled by ignorance n poor research: diabetes.

  • Anything at McDonald’s is not the healthiest way to go – but I tried a lamb burger today and it was pretty darn good. Once in a while wont kill anyone. Its a life of fast food that is dangerous
