A major reason in wife getting fat stories is a shift in dietary habits. For instance, if a family starts having more fried and fatty foods as part of their regular diet, the wife may gain weight. Stress can also play a role. When a wife is stressed, she may overeat comfort foods. Additionally, age can be a factor. As a woman gets older, her metabolism slows down, and if she doesn't adjust her diet and exercise accordingly, she'll start to gain weight. Some wives may also gain weight during pregnancy and then struggle to lose it afterwards due to the body's changes during that time.
One story could be that a wife started getting fat after having a baby. She was so focused on taking care of the new - born that she didn't have much time for exercise and ate a lot of convenient but high - calorie foods. Another story might be that a wife got fat because of a change in her job. She had a more sedentary job with lots of office snacks available, and over time, she gained weight. There could also be a story where a wife started cooking really delicious and rich meals for the family, and in the process of sampling her own cooking often, she put on some pounds.
I'm not sure if there are specifically extremely popular 'getting fat fanfiction' stories in a mainstream sense. However, within certain niche fan communities that are interested in body transformation themes, there might be some well - known ones. But it's not as common as some other types of fanfiction themes.
There are also cases in the bodybuilding community. Some bodybuilders go through a 'bulking' phase where they intentionally eat in a calorie surplus to gain muscle mass, but this also often results in some fat gain. They might have a diet rich in carbs and proteins and eat larger portions than normal. They do this to increase their overall size before they cut down the fat and show off their defined muscles.
One story could be a girl who started a new job that was very sedentary. She sat at a desk all day and had easy access to junk food in the office vending machines. She slowly started gaining weight as she was consuming more calories than she was burning. Another could be a girl who had an injury that prevented her from being active for a long time. She used to be very sporty but during her recovery, she ate a lot of comfort foods and gained fat.
One story could be about a girl who started overeating due to stress. She had a lot of pressure at school with exams and assignments. Instead of dealing with the stress in a healthy way like exercise or relaxation, she turned to junk food. Every day she would snack on chips, cookies, and drink sugary sodas. As a result, she gradually gained weight.
One common story could be a student who always buys junk food from the school cafeteria or vending machines. For example, they choose fried chicken and soda every day instead of healthier options like salads and water. Another might be a student who is too busy with schoolwork and extracurricular activities to exercise regularly, so they gradually gain weight. And there could be those who are influenced by their peers to overeat during lunch breaks or parties at school.
One success story could be that French women often practice portion control. They don't overeat and are used to having smaller but more frequent meals. For example, instead of having a large dinner, they might have a small plate of cheese, some fruit, and a glass of wine.
Some girls may have underlying health issues that can lead to weight gain. For example, thyroid problems can slow down the metabolism. Also, psychological factors are important. Social media can have an impact on a girl's self - image and eating habits. If she sees images of 'perfect' bodies all the time and feels bad about herself, she might overeat or develop an unhealthy relationship with food.
One common plot is the character's transformation journey. For example, a character might start out as a thin person and due to certain life events like a new job with a lot of stress - eating or a medical condition, they start to gain weight. And then the story could be about how they come to terms with this change in their body.
