Fast food is designed to be delicious, convenient and affordable, and that often means it’s energy-dense. A single combo meal can deliver a third to a half of an average day’s kilojoules. Knowing the typical numbers makes it easier to fit takeaway into your week without thinking twice.
Values here are typical generic figures. Recipes vary between chains, countries and even outlets. Most large chains publish nutrition information online and in store, check it for exact numbers.

How A Meal Deal Adds Up

|---|---|---|
| Double burger + medium fries + regular cola (375 ml) | 4,502 kJ | 52% |
| Double burger + medium fries + diet cola | 3,832 kJ | 44% |

Why Fast Food Is So Energy-Dense
- Frying adds fat, and fat carries 37 kJ per gram.
- Refined bread and batter are quick to eat and not very filling.
- Sauces, cheese and dressings add lots of kilojoules in small volumes.
- Portion sizes have grown, and “upsizing” often costs very little extra money.
Smarter Ways To Order
- Skip the upsize. Keep it regular or small.
- Swap the drink. Water, diet soft drink or sparkling water saves 600+ kJ.
- Choose grilled over crumbed or fried.
- Add a salad or vegetables instead of a second side of chips.
- Go easy on sauces or ask for them on the side.
- Share the fries.
Can Fast Food Fit Into A Healthy Diet?
Yes, occasional takeaway is part of normal life. The key is frequency and portion. A 4,500 kJ combo once in a while is very different from one every day. If you know a big meal is coming, a lighter breakfast and lunch can balance your day. Check your personal target with the daily kJ calculator.
