Fat fetishism

Fat fetishism is the strong or exclusive sexual attraction to overweight or obese people. As well as traditional attraction, the topic also incorporates feederism and gaining, where sexual gratification is obtained via the process of gaining body fat. Fat fetishism also incorporates stuffing and padding, whereas the focus of arousal is on the sensations and properties of a real or simulated gain.

Attraction
A 2009 study found that heterosexual male fat admirers preferred females that were clinically overweight and rated both overweight and obese women more positively than slighter individuals. The study also found that participants reacted positively to a much wider range of figures than a control group, even rating emaciated figures higher. It concludes "these findings suggest that an explanation for fat admiration may be that FAs are rejecting sociocultural norms of attractiveness".
