Maybe it's because people have certain expectations for the image of a warrior and weight gain doesn't fit that. They might think it makes the warrior less powerful or attractive.
It could be that the traditional idea of a warrior in manga is supposed to be fit and agile. Weight gain goes against that stereotype. Also, some readers might just prefer the visual aesthetics of a slimmer character for the warrior role.
One popular female weight gain fiction could be stories where a character goes through a lifestyle change that leads to healthy weight gain, like a young woman starting a new job in a food - loving community and gradually gaining weight in a positive way. Another might be about a female athlete who has to gain weight for strength purposes and her journey through it.
There are also 'female weight gain fanfic' that are set in a modern - day, slice - of - life scenario. Maybe it's about a college girl who gains weight during her freshman year. She joins a body - positive club on campus and through their activities and the new friends she makes, she comes to terms with her weight gain and even starts to see it as a positive transformation in her life.
I'm not sure of many mainstream popular authors specifically in this niche. However, there may be some indie authors who have a following in this area. It's a rather specialized genre, so it might not have as many well - known names as more common literary genres.
Once upon a time, a popular girl called Lucy. She was always invited to parties and was the center of attention. One summer, she went on a long vacation with her family. They stayed in a small town where there were all kinds of delicious local food. Lucy couldn't resist trying everything. She also became less active as there were no gyms around. By the end of the vacation, she had gained quite a bit of weight. But her friends still loved her for her kind heart. And she learned that real friendship doesn't depend on appearance. So she was confident in her new self.
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 overeating. If she got into the habit of consuming large amounts of food without proper balance, it would lead to weight gain.
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.
Poor diet. Maybe the teacher eats a lot of junk food like burgers and fries.
One popular weight gain visual novel is 'Dreaming Mary'. It has unique art styles and engaging storylines that incorporate the concept of weight gain in an interesting way.
I'm not sure about extremely popular ones in mainstream, but there are some works within the niche community. Some self - published e - books might be out there that deal with this theme.
