Question ID: 231712
Does Diet Coke actually have the same amount of calories as regular
Coke?  I heard that Coca Cola was sued because Diet Coke has calories,
and fined money, but did not have to change its label?  Can anyone
chemically show that Diet Coke is calorie free?

Hello hauffbm and thank you for your question.

In direct answer to your question:
"Does Diet Coke actually have the same amount of calories as regular 

The answer is no. 

"Q How many calories are in 'Coca-Cola'? 
A 'Coca-Cola' contains 41 calories per 100ml. 

Q How many calories are in 'diet Coke'? 
A 'diet Coke' contains 0.41 calories per 100ml."

Or, to put it another way, diet Coke contains 100 times less calories
than regular Coca-Cola.

Are you sure the story you heard was about calories?

Best regards

Here is my question in better words.

I have a friend who is trying to tell me that she remembers the Coca
Cola company getting sued about the calorie content of Diet Coke.  She
heard that Coke was sued, (by the FDA I believe) and was told to fix
the label showing Diet Coke does contain calories, or pay a large
fine.  Supposedly Coke paid the fine and continues to mislabel their
Diet Coke cans as having no calories, when in fact they contain just
as much as regular Coke.

I think that is a bunch of crap, Diet Coke contains Aspartame which
has essentially no calories.  I explained that to my friend and she
says she remembers the lawsuit.

I guess... Is there any record of this lawsuit?  Has anyone ever
chemically tested Diet Coke to show the calorie content?  How many
calories does Diet Coke contain?

Any info along those lines would be great.

Hi hauffbm-ga, 

No, there is no record on the FDA website of any type of recall or
enforcement report involving Diet Coke and its calorie content.  There
are however other recalls of specific manufacturing runs where the
wrong product was packaged in the wrong bottle.

For example –

Caffeine Free Diet Coke, in 2 liter PET containers.
Recall #F-587-8/F-588-8.

Manufacturer verbally and by E-mail on July 31, 1998.  
Firm-initiated recall complete.

14,557 cases were distributed.

Undeclared sugar - The product actually contains Caffeine Free
Coca-Cola Classic


Diet Coke in 2 liter plastic bottles. Recall #F-284-0.

Manufacturer, by E-mail on October 26, 1999, by press release issued
October 28, 1999, and by letter dated November 1, 1999. 
recall complete.

7,995 cases (8 bottles per case) were distributed. 

Product is labeled as Diet Coke but actually contained Coca-Cola
a regularly sweetened beverage.

Diet Coke, in 12 fluid ounce cans, in 16 fluid ounce bottles, and in 2
liter bottles.  Recall #F-543-2.

Product contains saccharin and saccharin is not listed as an


In another case, a petition was brought against Coca Cola regarding
differences between their bottled Diet Coke and their Fountain

" The subject matter of this petition is proposed remedial regulations
regarding products sold under the same brand name, but which contain
different ingredients in the non- labeled versions from the
ingredients listed in the labeled version. For example, bottled Diet
Coca-Cola lists that it is sweetened 100% with aspartame, while Diet
Coca-Cola, dispensed in a fountain format, is sweetened primarily with
saccharin. …..Primarily, it is sought to order Coca-Cola, and all
other manufacturers of products whose unlabelled versions’ ingredients
materially differ from the same branded product, to disclose this to
consumers on the labeled product, or otherwise effectively alert
consumers to the existence of such differences."


All other FDA recalls and enforcement reports involving Diet Coke


The calorie content of each product that thx1138-ga gave you above, is
correct. As you can see, regular Coke has 100 times the calories as
Diet Coke. Diet Coke only contains .41 calories per 100 ml. This is
less than one-half of a calorie.

This means that Diet Coke does conform to the FDA labeling
requirements with regard to the term "No calories" or "calorie free"

From the FDA ---

b) Calorie content claims. (1) The terms ``calorie free,'' ``free of
calories,'' ``no calories,'' ``zero calories,'' ``without calories,''
``trivial source of calories,'' ``negligible source of calories,'' or
``dietarily insignificant source of calories'' may be used on the
label or in the labeling of foods, provided that:

    (i) The food contains less than 5 calories per reference amount
customarily consumed and per labeled serving.



And yes, the calorie content of Coke and Diet Coke has been measured.
All companies must provide proof to the FDA that their product
conforms to the labeling claims.

That should clear things up for you. I'm not sure what your friend
actually heard, but it wasn't that Diet Coke has as many calories as
regular Coke and it wasn't that Coca Cola was sued by the FDA for
calling its Diet Coke calorie-free when it wasn't.

Hope that helps you out!

Thanks for your question –
