This question is out of curiosity. I have a new colleague. I haven't seen him going out for lunch or eating anything else but chocolate. He eats only chocolate bars whole day, about 3 big bars every day.

I didn't ask him why, since it seems personal. But I am curious about how eating only chocolate affects our nutrition system, regarding to protein and stuff.

    how exactly do you know what he is eating at other times of the day, and weekends? This could just be a sampling error. Commented Mar 16, 2018 at 19:41
  • @GrahamChiu You could just accept the answer as written.

1 Answer 1


1 oz (28g) of dark has 155 calories. If you scale these 155 calories to 2000 (13 oz) then it looks like this:

enter image description here

Source: United States Department of Agriculture, National Nutrient Database for Standard Reference Release 28, Basic Report: 19902, Chocolate, dark, 45- 59% cacao solids

Below is a table with the daily value:

% Daily Value*      
Total Fat 9 g          13.00%   167.74%
Saturated fat 5 g      25.00%   322.58% 
Cholesterol 2 mg        0.00%     0.00%
Sodium 7 mg             0.00%     0.00%
Potassium 158 mg        4.00%    51.61%
Total Carbohydrate 17 g 5.00%    64.52%
Dietary fiber 2 g       8.00%   103.23%
Sugar 14 g      
Protein 1.4 g           2.00%    25.81%  

Naturally it is high on fat. About the only guidelines chocolate meets are cholesterol and fiber.

Chocolate is also low on essential vitamins.

Clearly over the long term it will negatively impact health.

3 each 10 oz bars is even more. It is 4,650 calories.

    interesting, I would not have expected it to provide enough fibre. For reference are these numbers for milk or dark chocolate, and what quantity of chocolate provides the amounts in the last column? Commented Mar 16, 2018 at 15:57

    What cholesterol guideline? We do require references. Commented Mar 16, 2018 at 19:42

    @GrahamChiu and paparazzo: Why is the tone in the comments so hostile? I think we‘re all on the same page that quality should improve on Health.SE. I think it’s important to note that anyone here is trying to bully someone else, it’s just that there a guidelines and on meta there happen to be quite a few discussion about improving quality, and our dissatisfaction with the way of the site. // I think this answer is sound and with a link to any daily recommendation and the ingredients of a random chocolate piece, the question would also meet the guidelines for references.

    See, it doesn't show up in my google search. (Google gives different results based on location and language, obviously). That's what I'm having the problem with. You need a reference in your answer, and just google it isn't a reference. Google probably got that number from somewhere...
