Feederism, a sexual fetish involving a preference for making a partner gain weight, has transitioned from private relationships to online platforms. In this practice, one person, referred to as the feeder, provides food to their partner, known as the feedee, in a way that is often seen as romantic within a relationship. However, when one partner becomes sexually aroused by the act of feeding and repeatedly engages in it to cause weight gain, it becomes a sexualized activity. This paraphilia, or atypical sexual preference, is sometimes compared to sadomasochistic practices, although it is typically consensual and negotiated between partners. On websites focused on BDSM, there are advertisements where individuals of any gender seek partners for feeding activities. Some describe themselves as "complexed by [their] weight" and look for feeders to help them gain more weight. Feederism challenges traditional expectations of slimness, which can align with body-positive ideals. However, the act of encouraging a partner to gain weight can be seen as oppressive, similar to pressuring someone to lose weight. In heterosexual relationships where the feeder is male, this dynamic may reinforce male dominance. In extreme cases, feederism can involve force-feeding, the degradation of the feedee’s body, or even their physical dependence on the feeder. However, not all feederism scenarios follow patriarchal structures. Some women enjoy being feeders and find pleasure in seeing men gain weight, which can disrupt typical power dynamics. In certain gay communities, weight gain is often mutual, providing pleasure to both partners. These communities use platforms like Grommr, a social network designed specifically for such interactions. Feederism has gained popularity on platforms such as OnlyFans, MYM, and websites like Fantasy Feeder or Feabie, which claims to have over 100,000 members. The content ranges from couple feeding sessions to solo model meals, which are accessible through subscriptions or on request. Viewers can pay for specific performances or send gifts from a food wishlist, effectively becoming feeders themselves. This practice has established itself as a niche but significant part of the online sex work economy. Some creators, like Reenaye Star, describe the satisfaction of viewers as a niche fantasy or aesthetic. Others, like Antonia Graham, find the activity fulfilling but not necessarily a lifelong pursuit. Feeder models often face societal discrimination and health risks, including cardiovascular issues, diabetes, and joint problems. Losing weight can be difficult due to the risk of losing their audience or career. Some models are drawn to weight-loss treatments like Wegovy, Mounjaro, and Saxenda, as seen in the case of Samantha Mason, who lost over 300 kilograms through a strict diet and medical supervision. Despite health improvements, she received messages questioning her beauty. The question of consent and control in feederism is complex, with researchers like sociologist Evan Stark and lawyer Leyla-Denisa Obreja suggesting a "continuum" of thresholds. If a feedee model were to die from on-camera activity, legal responsibility for viewers, subscribers, or donors could be questioned. As feederism grows, its implications on health and legal boundaries may be tested in courts.
