"I'm sure to lose weight now!"

I'd like 20 tacos of grilled meat, some pozole with pork legs... oh, and a large diet soda, 'cause I want to lose weight!
—"La Dieta", by the Mexican group La Fresa

A standard comedic effect used in various media to emphasize the overindulgence that came before. In various talk shows that featured exceptionally obese people, they would often show a fast food customer ordering an exceptionally large meal including multiple sandwiches, fries and desserts, and concluding with, "and a Diet Coke."

Despite being a staple joke on obesity and hypocrisy (especially the tired "Americans are fatasses" routine), it happens in Real Life for various legit reasons such as diabetes, calorie intake (soda averages 150 to 200 calories a can; a heavy soda drinker can see a tremendous benefit from cutting those calories), or simple taste preference.

Related to Hypocritical Humor, and also overlaps with Arson, Murder, and Jaywalking. A specific example of the Perfect Solution Fallacy.

Examples of And a Diet Coke include:


  • A Channel 4 "Friends is sponsored by Nescafe" clip had two women drinking coffee. The one with the huge cream cake in front of her was offered the sugar and reacted with horror, taking sweeteners out of her handbag.
  • There was a Diet Coke commercial from the '80s featuring a Sumo wrestler being told by his master that he needs to greatly increase his calorie intake, then after Sensei exits, the wrestler looks around, and pulls out and taps a can of Diet Coke while the theme "Just for the taste of it" starts playing.
  • Back when William "The Refrigerator" Perry was a big name in American football, McDonalds did a commercial starring him. The young woman taking his order (whose height, by the way, only went up to about the middle of his chest; The Fridge was a big guy) read it back to him: "That's four McDLTs, two large fries...and a diet Coke?"

Anime and Manga

Comic Books

  • Marvel Comics once did a gag issue of its What If? title, featuring short gags of a single page or less. One gag was "What If Tony Stark had an eating problem instead of a drinking problem?"

  • In Superman II, Lois is using a citrus juicer to squeeze a fresh glass of orange juice "because it's good for you"... while she's smoking.

  • Done in A Cinderella Story.
  • Also done in True Romance when Christian Slater's character goes to buy "the two biggest, fattest burgers" a burger stand has, two chili fries... and a Diet Coke. This is done in contrast to his wife getting beaten savagely—nay destroyed—by a very angry James Gandolfini.
  • In The Nutty Professor 2, Sherman's mother mentions her latest diet: You can eat as much as you want, as long as you also drink lots of grapefruit juice to help digest it. Presumably she thought the citric acid would destroy the food completely.

Then he devoured three bowls of mussel stew, a pound of pickled mallows, two pounds of steamed snails, three servings of soft-shelled crabs, two plates of sweetmeats, ten honey cakes, and a watermelon. The proprietor wondered whether the esteemed guest might care for six or seven quarts of peaches in heavy syrup, but the merchant explained that he was on a diet and would be forced to settle for a gallon of green tea flavored with pine kernels.

Enos: You want that pie a la mode?

Roscoe No Enos, I don't want it a la mode. I gotta watch my calories!
