Calories burned per tweet
Alright, we are going to try to figure out how many calories are burned per tweet. As a disclaimer, this is just for fun.
The Data:
Average word length: 6 characters
“Numbers regarding total characters are based on an estimated average word length of five, plus a space, or six characters per word.”
Average typing speed: 60 wpm
An average typist reaches 50 to 70 wpm, while some positions can require 80 to 95 (usually the minimum required for dispatch positions and other typing jobs), and some advanced typists work at speeds above 120.
Calories burned while typing; this one is more difficult. There are a lot of different sources on this, but the most reliable seems to be bodybuilding.com. They estimate the average person burns about 2.65* calories per minute.
*Calculations based on a male weighing 185 lbs (84kg) with a height of 6′1″ (me)
So assuming 140 character twitter post (we’re exercising here, you’ve gotta do max reps).
140 / 6 = 23.333 words per tweet
23.333 words / 60 wpm = .389 mins per tweet (or about 23 seconds)
.389 mins per tweet * 2.650 calories per minute = 1.031 calories per tweet!
Of course calculations so complex will vary from person-to-person, but I think it is safe to assume that you burn 1 calorie per tweet. Then again, who knows how many calories are burned when tweeting from a mobile device…

Very funny – Coop
I love this post – I guess I’ll have to spend a lot more time on Twitter to stop going to the gym!
Brilliant. Just found your blog, I’ll be here often. Love your point of view.

I enjoyed reading this post. As a fitness professional and health educator, I often pondered this question, myself. Although I do believe that 2.65 calories per minute is a bit high… too high, in fact. You are correct in saying that caloric expenditure is certainly based on your weight, in addition to your fitness level, metabolic rate… and maybe on the content of your tweet? (LOL)
But, assuming your calculations are true and you burn about 1 calorie per tweet… then you would need 3500 tweets just to lose 1 pound. And that’s a lot of tweeting…
Thanks for a great post.
Some people burn off a chocolate bar a day by this calculation!
Love the article, well done!
