What does 8,700 kilojoules look like?

What does 8,700 kilojoules look like?
No video selected.

8,700 is a magic number in nutrition. It’s the number of kilojoules (kJ) that is the “average” intake for adults in Australia, if the surveys are correct.

It’s widely used as a benchmark figure and as the basis of food labels such as the Percent Daily Intake values.

Recently kilojoules have appeared on fast food menu boards and they use 8,700 as the yardstick to assess their foods against. Here's my take on it.

 

8700 Pizza Hut with arrowObviously 8,700 kilojoules a day is an average. The actual number of kilojoules you need will vary depending on your age, gender, life stage (if you’re growing or are pregnant as this calls for more energy), weight, height and how physically active you are.

A very active 16-year old, for example, requires 12,000 kJ a day, which is 4,000 kJ more than a sedentary 70-year-old. And then there’s that wonderful thing known as genetic inheritance. Most of us know people who always ‘burn off their food quickly’ and rarely put on weight –they most likely come from a family with a similar metabolic tendency!

The Legends pizza ad shown has 6654 kJ in the whole pizza which becomes 832 kJ per  wedge. Think if this is a realistic serve size - would you eat one-eighth of a regular pizza? Unlikely. You'd probably tuck into half of it (3327 kJ) or at least two wedges (1664 J).

8,700 kilojoules = 2,080 Calories

In the old numbers, 8,700 kilojoules is equivalent to 2,080 Calories. Or simply round it off to 2,000 Calories for ease of remembering.

Who should aim to eat 8,700?

  • Women between 19 and 50 doing light activity and who weigh between 55 and 60 kg.
  • Women between 51 and 70 doing light activity and who weigh between 60 and 65 kg.
  • Women over 70 doing light activity and who weigh between 70 and 75 kg.
  • Men over 70 doing light activity and who weigh between 55 and 65kg.
  • Girls around 12 or 13 doing light activity.
  • Boys around 11 or 12 doing light activity.

Your individual circumstances will dictate whether you need either MORE or LESS than 8,700. Click here for a full table of recommended daily intakes for kilojoules. Or see an Accredited Practicing Dietitian for more personalised nutrition advice.

8700 Cheesecake Menu2 with arrow

The cheesecakes shown above give you the kilojoule counts for the whole cake. You'd have to divide that figure by 8 or 10 depending on the number of serves you cut. These counts must be on their website and also on order forms.


How much food does 8,700 represent?

1. The ‘average’ daily diet

Here’s how a typical food day could look like to add up to around 8,700 *.

MealKilojoules
Breakfast (17% of the total day’s food)  
2 Weet-Bix 480
Reduced fat milk, about 1 cup 535
Honey, 1 tablespoon 95
Banana 335
Morning Tea (17%)   
Choc chip muffin 925
Cappuccino made with regular milk 465
Sugar, 1 teaspoon 65
Lunch (20%)  
Toasted cheese and tomato sandwich 980
Tub of strawberry yoghurt, reduced fat 760
Afternoon Tea (6%)  
Muesli Bar 325
Apple 300
Dinner (40%)  
Spaghetti with bolognaise meat sauce topped with grated cheese 2,355
1 glass red wine 290
2 TimTams 790
TOTAL 8,700

* Figures have been rounded to the nearest 0 or 5 for ease of reading. Figures calculated using Foodworks 6.0.


2. A fast food way to reach 8,700

If you eat a lot of fast food, it won’t take you long to reach 8,700 kilojoules, Check out this day’s meal intake below and you’ll see that only six fast food items take you to your 8,700.

MealKilojoules
Breakfast (0%)  
None 0
Late morning  (40%)  
Gloria Jean’s Large White Chocolate Mocha 1,870
Banana bread, toasted (Gloria Jean’s) with butter 1,615
Lunch (20%)  
McDonald’s Cheeseburger 1,190
Coca-Cola 375mL can 675
Dinner (40%)  
Super Supreme Pizza, thin crust 2,350
Mars bar, 53g 1,050
TOTAL 8,750

Take note: Lunch doesn’t even include the ubiquitous “fries with that”!


Where does the figure of 8,700 come from?

It comes from national surveys of what Australians supposedly eat. According to Food Standards, we eat, on average,  around 8,700 kilojoules a day.

8700_Cookies_Subway_with_arrows

This figure of 8,700 MUST be stated somewhere on fast food menu boards. See the cookie example above from Subway. See how each cookie has its kilojoule count displayed PLUS there's the average adult intake of 8,700 along the base. 

 

What percentage? Divide the kilojoules by 8,700 and compare

8700 Bondi Burger

Yes, it's epic all right! This Bondi Burger gives you 35% of your day's suggested total. Divide 3,180 by 8,700 and you get 35%. Ask yourself - do I want to eat 35 per cent of my total intake in one item?

    Product snapshot: Tomato pasta sauces

    18 September 2023 by, Catherine Saxelby

    What’s in your favourite tomato pasta sauce, and how much of it? Here are the most popular sauces reviewed for your reading pleasure.

    I’ve rated nine of the most popular tomato pasta sauces in terms of their nutrition, ingredient lists and jar size. You’ll find many of these in your local supermarket. The sauces are ranked:

    • from Italian (Italy grows the reddest full-flavoured tomatoes) to Australian
    • per 100 grams, which is equivalent to 3½ ounces (the standard for comparing food products)
    • by serving size (varies between brands but is generally 100–175 g in size)
    • by ingredient list, jar size and where made (with each product’s website as the source)

    The bottom line

    When you’re next out shopping, run your eyes down the per 100 g column and look for products containing less than 400 mg sodium AND less than 5 g fat (which equals 5% fat). Most of the brands are below these levels. I like Barilla, Sacla, Leggo’s, La Gina and Mutti – but that’s just me!

    Intermittent fasting vs daily calorie restriction

    3 May 2023 by, Catherine Saxelby

    As you probably know already, intermittent fasting (IF) has gained favour as an alternative regimen to daily caloric restriction (DCR). Fasting is shown to extend the lifespan of rats, and has been associated with metabolic benefits in humans, yet the results so far have been inconsistent. So, which regimen is best for healthy weight loss?

    What sort of a diet should you follow to lose that excess weight? These days, it’s pretty confusing with high-protein Keto advocates clashing with plant-protein followers … as well as intermittent fasters, juice-only dieters, no-carb dieters and no-animal (aka plant-based) dieters. Plus all the ads for anti-hunger supplements, meal-replacement shakes and home-delivered meals, more of which somehow appear every day. So, what sort of diet should YOU follow to lose that excess?

    These days, protein shakes aren’t bought by just body builders – they’re so popular that you can readily buy a 400 g tub at your local supermarket or service station. And with tempting claims such as ‘Facilitates muscle toning’, ‘Contains transformation-making protein’ and ‘Tastes incredible, mixes easily’, why wouldn’t you grab one? But protein shakes aren’t the magic answer to all your weight-loss woes. Let’s take a look at what you get for your money.

    How to lose weight WITHOUT going on a diet

    14 October 2020 by, Catherine Saxelby

    The word 'diet' is a turn-off for most people. It sounds hard, unpleasant and unpalatable. Losing weight doesn’t have to be hard AND it doesn’t have mean sticking to a 'diet'. You can forget Paleo, Keto, Vegan and Raw, Gluten-free and Intermittent Fasting. To lose weight, you don’t have to follow any specific diet. What you need is simple, healthy, nutritious food and a few tips and tricks.

    What IS a healthy balanced diet for weight loss?

    16 September 2020 by, Catherine Saxelby

    Healthy weight loss happens when you lose weight slowly and steadily (around 1 kg or 2 pounds weight loss a week). Your goal is to lose weight while still getting your essential nutrients but from smaller portions. You certainly don’t want to be tired with no energy! That’s why you need regular healthy meals and snacks on hand to ensure your vitamins, minerals, omega-3s and fibre needs can be easily met. There is a new range of healthy weight loss meals available and it’s one that I’d like to recommend. With these ready meals, you’ll say goodbye to meal planning, shopping, meal preparation and cooking.
