This is not just a test of your knowledge of calories but also a test of your confidence in your own knowledge. Most of us think that we know more than we actually do.

Below you will see a list of 10 meals from popular fast food chains. Write down your estimate of the calorie content of each meal. No need to come up with a precise number; instead just provide a low and high estimate of each meal’s calorie count.
For example, if asked to indicate the calorie content of a Big Mac, you might think that it most likely has somewhere between 300 calories (low estimate) and 600 calories (high estimate).
Your goal is to identify high and low estimates such that the right answer falls between the two numbers you write down 90% of the time. In other words, this means that you should get at most one answer (10% of responses) wrong.
|Dunkin’ Donuts multigrain bagel with lite cream cheese|
|Chili’s citrus fire chicken and shrimp fajitas|
|Denny’s smoked sausage scramble|
|Krispy Kreme’s whole wheat glazed donut|
|McDonald’s Quarter Pounder (without cheese)|
|Panera Bread’s broccoli cheddar soup (8oz) in a sourdough soup bowl|
|Romano’s Macaroni Grill grilled salmon teriyaki|
|Ruby Tuesday’s turkey burger (with fries)|
|Starbucks’ grande 2% white chocolate mocha and a bran muffin with nuts|
|Uno Chicago Grill’s classic deep dish pizza (individual)|
Now, let’s find out how you did
Dunkin’ Donuts multigrain bagel with lite cream cheese: 490
Chili’s citrus fire chicken and shrimp fajitas: 1,360
Denny’s smoked sausage scramble: 1,480
Krispy Kreme’s whole wheat glazed donut: 180
McDonald’s Quarter Pounder (without cheese): 410
Panera Bread’s broccoli cheddar soup (8oz) in a sourdough soup bowl: 880
Romano’s Macaroni Grill grilled salmon teriyaki: 1,230
Ruby Tuesday’s turkey burger (with fries): 1,393
Starbucks’ grande 2% white chocolate mocha and a bran muffin with nuts: 900
Uno Chicago Grill’s classic deep dish pizza (individual): 2,310
If you got all answers right or made only one mistake, you are an exception. If you did not — don’t get depressed. Most people don’t. On average only half of the answers to this quiz are correct, significantly below the 90% target.
As you might have guessed by now, this was not just a test of your knowledge of calories but also a test of your confidence in your own knowledge. As this quiz shows, most of us are overconfident, thinking that we know more than we actually do.
