Sometimes, the motivation is related to a character arc. The anime girl might start off as a very self - conscious and skinny girl who is always trying to fit into the 'perfect' body image society expects. But as the story progresses, she realizes that she can be happy and confident at any size. So she starts to embrace food and life more fully, which results in her weight gain. It could also be that she is influenced by her friends or family who are all big food lovers and she gradually adopts their eating habits, leading to her own weight gain.
In some stories, the motivation for an anime girl's weight gain is to fit into a certain role or community. For example, she might want to join a group that values plumpness or a food - loving club where everyone is a bit on the chubby side. So she deliberately gains weight to be part of that group. Also, it could be due to a wrong perception of beauty. She might see some curvier body types as more beautiful and tries to gain weight to achieve that look, not realizing the potential health risks.
One common plot is that the anime girl might go through a period of stress eating. For example, she could be facing a lot of pressure at school like difficult exams or mean classmates. So she starts eating more junk food, like lots of chips and ice cream. This leads to her gradually gaining weight. Another plot could be that she has an injury that stops her from being active. So she doesn't burn as many calories as before and starts to gain weight while still eating the same amount of food. Sometimes, there are also stories where she discovers new delicious foods and becomes so obsessed with them that she overeats and gains weight.
One reason could be overeating due to emotional issues. For example, if she has problems at home or with friends, she might turn to food for comfort. Another reason could be a lack of physical activity. Maybe she's too busy being mean and not focusing on taking care of her body. Also, it could be related to hormonal changes, which can sometimes cause unexpected weight gain.
One reason could be a change in diet. College cafeterias often offer high - calorie and junk foods. If a girl starts consuming these regularly, it can lead to weight gain. Another reason is a lack of exercise. College life can be busy, and if she stops her regular physical activities like sports or workouts, she'll gain weight. Also, stress can play a role. High stress levels might make her overeat.
One reason could be a change in lifestyle. For example, if she used to be very active in the goth club scene, dancing all night, and then she has an injury or something that stops her from being so active, she may gain weight. Another reason could be a new hobby like baking goth - themed treats as I mentioned before. Also, a new relationship where her partner cooks a lot can lead to weight gain.
Another theme is the emotional aspect. Stress, happiness, or other strong emotions can sometimes be associated with weight gain in anime stories. For example, a character may overeat when they are stressed or happy, leading to changes in their body. It can also be used to explore how the character copes with these emotions. In addition, sometimes these weight gain stories are also related to self - acceptance. The character may initially be unhappy with their weight gain but later learn to accept themselves, which is a positive message in many cases.
In 'My Love Story!!', Takeo's friend Sunakawa might be involved in some imagined weight gain stories by the fans. Since he is often shown eating junk food while watching TV, some fans create stories where he starts to gain weight gradually. These stories are more about exploring different character aspects in a light - hearted way.
Some anime girl weight gain stories involve a bet or a challenge. For instance, she might take on a challenge to eat a large amount of food within a certain time, not realizing it will lead to significant weight gain. Or perhaps she makes a bet with a friend that she can resist certain temptations, but fails and gains weight as a result.
In 'Food Wars! Shokugeki no Soma', there are characters who gain a deeper appreciation for food which can sometimes lead to them enjoying it so much that they might gain a bit of weight in a comical sense. For example, some of the characters' eating habits during the intense cooking battles can be seen as leading to such situations. It's not a central theme but it's an interesting aspect to consider in the context of a 'weight gain anime story'.
A little girl living in a cold climate may experience weight gain. In winter, her body needed more energy to keep warm. Her mother cooked warm, hearty meals like stews and casseroles. These were rich in carbohydrates and proteins. The girl also ate more dairy products like cheese and milk. As a result, she gained some healthy weight during the winter months.
