Eating as much as an elephant eats.
What are you at, getting terribly fat?
What do you think will come of that?
I don't like the look of it."
In comes this Stock Aesop, which does its damnedest to demonize too much junk food and glorify exercise. Generally, it involves one or more characters getting hooked on some sort of junk food, making their health deteriorate badly and expanding their waistline. Usually, the rest of the group (if it's one person addicted) or the sole outlier (if the whole group's addicted) will have to get things back to normal.
This won't stop the writers from having the protagonists eating more junk food in the next episode, though. After all, Status Quo Is God.
These morals tend to get heavy-handed which, combined with their increasing frequency since the Turn of the Millennium, can quickly make them the bane of viewers. In all fairness, though, many children in developed countries have been getting heavier to the point of obesity in recent years (as have many adults, for that matter), so obviously the higher-ups want to tell people about it.
One scary if somewhat silly way to present this aesop that sometimes shows up in horror, sci-fi and fantasy works is to show that fatter humans are more desirable prey for people-eating monsters and aliens. It moves the aesop into much darker territory, but the message can easily get lost because being eaten by a Martian isn't likely to happen to any audience member.
Contrast Balloon Belly, Temporary Bulk Change and Fat Comic Relief (which are about fat people Played for Laughs) and Acrofatic (which is about fat people that can achieve impressive physical feats despite their weight). Also contrast Be Yourself if a character slimming down has a negative effect on their character or they're not doing so except to please someone who otherwise would value them less. See also Diet Episode. Compare Disease-Prevention Aesop, Missed Meal Aesop, and Sleep Aesop for more health-related Aesops.
- Kirby: Right Back at Ya! has an episode entitled "Fitness Fiend", which has Dedede obtaining potato chips designed to be very addictive and to cause the consumer to increase in size by a great deal.

Fortunately, unlike other examples, the Aesop is delivered subtly and requires some interpretation to fish it out.
- Used in a throwaway scene in Stargate SG-1 season 6. As the season begins, alien refugee Jonas Quinn is shown eating in nearly every scene at the SGC.

This aspect of Jonas' character was quietly dropped after that.
- In an episode of Mighty Morphin' Power Rangers, Tommy lectures a student of his about healthy eating.

- That's So Raven has an episode called "Food for Thought", in which Raven's school becomes a food court full of junk food (which is at least partly Truth in Television, sadly).

- American Dad! subverts this trope in "The American Dad After School Special". After it's pointed out that he's put on some weight, Stan takes it to extremes and tries to get as skinny as possible. At first it looks like Haley and Francine are trying to sabotage him by putting fat in his diet food as payback for banning Steve from seeing his fat girlfriend Debbie, but in a twist, it's revealed they're trying to get him to put on weight because he's suffering from anorexia and is actually so thin, you can see his skeleton.

- Big City Greens did this with the episode "Fast Foodie". A new Burger Clown opens where Big Coffee stood and Cricket makes a wager with Bill he and Tilly can eat there all the time for every meal with no side effects.

It is that point he learns his lesson and vows never to eat Burger Clown food all the time again, but Bill gets stuck as well, causing the restaurant to be closed down. Cricket is not sad however, as not having his favorite restaurant next door is for the best.

- Subverted in an episode of Home Movies in which Brandon and Jason become overweight from overindulgence in junk food and decide they've become "fat enablers"; when they're apart they drop the weight just fine, but when they spend time together they revert to their old overindulging ways. Subverted because at the end of the episode they decide that their friendship is more important to them than their weight, they rope Melissa into joining them to become morbidly obese, and they make a series of movie parodies like "Fat Club." Then they're back to normal in the next episode.
- Defied in an episode of Super Mario World. King Koopa opens a fast food restaurant and the cave people become hooked on their food.

Besides eating habits themselves, it's a more general satire of following your heritage even at the expense of your health.
- The Simpsons:
- One episode has the town declared as the fattest town in America. This greatly concerns Marge and she manages to convince other people to enforce a ban on sugar so that everyone can start eating healthier.

- Zig-zagged in "King-Sized Homer" where Homer purposely gains weight to the point of weighing over 300 pounds because it would make him legally disabled, thus he can work from home and never have to physically go to work. A moment later, he gets a warning from the power plant that there will be a meltdown if the problem is not taken care of right now. Homer races to the source and winds up plugging up the hole with his enlarged rear, which somehow stops the threat. Homer realizes that if had he not gained excessive weight, he would have fallen to his death, which Lisa ironically remarks as well. Homer then decides he has to lose weight so Marge would not be turned off by his body anymore. Mr. Burns tries to get Homer to exercise, but gives up after seeing Homer is too fat to do a proper sit up and decides to just get him liposuction.
- In "The Heartbroke Kid", after Principal Skinner signs a contract with a vending machine company sponsored by hip-hop artists to allow them to sell their products at the school, Bart becomes greatly hooked on the excessively unhealthy snacks and consumes them frequently, which results in him growing considerably obese and developing a serious addiction toward junk food. One day, he suffers a heart attack and is taken to the hospital, where an X-ray scan reveals there are three malted milk balls clogging his arteries and a wad of Laffy Taffy stuck on his liver. Bart is put on a diet, but, when his addiction is too severe, the entire family and a few Springfieldians stage an intervention and send the boy to Serenity Ranch, a rather expensive weight-loss camp led by Tab Spangler, a fitness guru voiced by Albert Brooks. Bart ultimately overcomes his addiction after Tab shows him the sacrifices his family is making to afford the camp's bills (namely turning the house into a youth hostel for a bunch of rude German students), whereupon he goes back to the school, smashes the vending machines apart and recovers the money he spent on them to bring it back to his family.
- In "Walking Big & Tall", the characters learn that there is no such thing as a perfect body image, being obese and underweight carry health problems that can turn fatal.

You shouldn't promote or shame either body type but you still need to consider either yours or their health.
