When someone is eating lunch alone in a communal context (school, army, etc.), it means they're being actively shunned by everyone else, or the student is the New Kid and has not yet made any friends. It rarely ever means that they chose to eat lunch by themselves. Often, their return into the fold will be symbolized by someone else accepting to have lunch with them. Or if they keep their outcast status, having lunch with them will be a sign of independence of mind and refusing to follow the herd. Or it could be because that person has very poor hygiene for days on end.
May end up being the fate of the Alpha Bitch when her poor treatment of others comes back to haunt her.
Very much Truth in Television. There are introverts who enjoy the solitude, and even extroverts with normal social lives are known to do it for various reasons. More rarely, there are numerous anxiety disorders that can make one extremely self-conscious and uncomfortable about having others watch them eat. Another reason for it to happen is that cooking and eating are (somehow) parts of one's culture, so eating together can cause various Culture Clash.
- Kuroe Akaishi of Kaiju Girl Caramelise initially spends her lunch breaks alone because her Involuntary Shapeshifting is reliant on her emotional state — and it's harder to stay calm when interacting with other people. She's initially annoyed when popular boy Arata Minami strikes up a conversation during one such lunch, but it turns out that he also prefers to get some peace and quiet away from the throngs of classmates who typically congregate around him.
- In Sailor Moon, Makoto is seen eating her absolutely delicious and abundant lunch alone since everyone fears her for her huge height and bad reputation. Then Usagi bursts in and Mako lets her have some of it.
- Ai Haibara in Detective Conan claimed she was that. As a Child Prodigy, it is of course due to Intelligence = Isolation.
- In The Prince of Tennis, Kaidou Kaoru always eats lunch alone... to the point that the other students in his class scoot their desks away from his in order to give him a wide berth. In this case, it's not so much that he's shunned as that everyone is scared of him/creeped out by his aloof attitude. It doesn't help that he eats his mother's very high-quality traditional food in an overly reverent manner, which freaks them out.
- In the beginning of CLANNAD, Nagisa Furukawa is eating lunch alone at school because she's repeating her last year, so she doesn't know anyone in the current senior class.

- Justified in a tear-jerker way in Angel Beats!. Due to the system that the afterlife works in, Angel will always eat alone since being friends with her is automatic grounds to Ascend to a Higher Plane of Existence. This picture sums her life up,◊ and for all we know, she may have lived this "life" for years. Granted that this was the implication, not the truth, as the members of the of the main cast found out when they befriend her, it still takes quite a while before they're able to 'move on'. She would eat alone because the people she wanted to help were antagonistic towards her instead.
- Bleach: Uryuu Ishida does this early on, and objects to being invited by Ichigo to eat with others.
- In Umineko: When They Cry, Ange essentially eats lunch by herself every day because she is constantly shunned and bullied by the other girls at her private school. However, she uses this time to read her cousin Maria's diary, which she sees as a way of communing with her, and later learns to summon magical beings, Sakutarou and the Seven Sisters of Purgatory, to keep her company. Depending on your perspective, this is either genuine magic and a great source of happiness for the long-suffering Ange, or a truly pitiable case of someone who has to resort to deluding herself just to stay sane.
- Rei from 3-gatsu no Lion is usually eating alone on the stairwell to the roof of the school or the roof itself, since he's yet to forge any bonds with his classmates. Only Hayashida, his teacher, comes up to eat with him on occasion.

- Chihiro and Yugami, who sit next to each other, both do this in Yugami-kun ni wa Tomodachi ga Inai. In the former's case, she's a New Transfer Student that's yet to make friends, while the latter insists on invoking this trope. He's rather displeased to discover Chihiro is eating lunch beside him.
- How would this trope not be used when Haruka of Kotoura-san has a serious case of All of the Other Reindeer in the Downer Beginning? The situation actually reminds viewers of the Instant Mind-Reading Radius at the first scene of the anime.

- No Matter How I Look at It, It's You Guys' Fault I'm Not Popular! deals extensively with the subject of social isolation, making this a fairly common trope.
- Tomoko suffered this badly for the longest time. Because she had no friends, and her anxieties left her unable to talk to people, all of her lunches were spent eating alone surrounded by groups. This got really bad when someone once took her desk, which forced her to consider alternative places to eat, ultimately choosing to have lunch in a room reserved for storing extra chairs and desks. When that was taken away, she just settled with not eating lunch at all.
- While Kotomi is generally better off than Tomoko, she's shown resorting to eating in the bathroom when her Only Friend is absent. Because Tomoko considers this the absolute lowest thing a person can do, she can only look at her with absolute pity when she finds out, despite disliking her.
- Smax in Top 10 initially eats lunch alone by choice.

We get a brief shot of a lone kid gazing into the middle distance and taking a pensive forkful of his canned peaches; then it's back to Seth and Evan, and Mr. Glansberg is never seen or heard from again.
- Happens to Riley after moving to San Francisco in Inside Out.

The other commanders—envious, spiteful or intimidated—pointedly withhold the congratulatory rituals.

- This is bookended nicely at the graduation ceremony in the final episode when the other kids give Malcolm and Reese a wide berth and the other guests give the rest of the family a wide berth. Though this time, the smell provides an in-episode reason. Doesn't excuse everyone besides the family giving Malcolm applause as he's about to make his valedictorian speech, however.

After Monica points out what she just did Rachel reconsiders and goes through an Internal Monologue breaking up with herself so she can ask the guy out. Unfortunately his internal monologue makes it clear he won't be going out with her because "you're a freak who eats alone".
- Weirdly subverted in Gilmore Girls, in which Rory often ate lunch alone in high school, reading and listening to music, until she was encouraged by her headmaster to sit with other students at lunch. Unfortunately, the kids whom she chooses to befriend have a weird initiation ritual where they "kidnap" her in the middle of the night, break into the headmaster's office and get in trouble.

Captain Janeway dines separately due to her rank, though she sometimes invites her Number Two Chakotay for a home-replicated meal.
