Fat admiration fetish

Fat fetishism, also referred to as fat admiration,is the usually heterosexual sexual attraction to overweight or obese females . As well as traditional attraction the topic also incorporates "feederism", where sexual gratification is obtained via the process of gaining body fat.

A 2009 study found that male admirers preferred females that were clinically overweight and rated both overweight and obese women more positively that 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".

Fat fetishists typically find fondling of an overweight person's adipose tissue arousing. They may be aroused by the presence of a pannus or other hanging flaps of skin such as those on the thighs, arms, and back. Fat fetishists who are attracted to overweight men may be aroused by a fat man's larger breasts (a condition referred to in the medical literature as pseudogynecomastia). A male fat fetishist may enjoy inserting his penis between the deep folds of skin on an overweight person's body, and thrusting to orgasm in a practice similar to mammary intercourse.

Feederism describes sexual relationships where both members obtain gratification from the gaining of body fat. Feederism refers to the acts of feeding, encouraging eating, or being served large quantities of food. Sexual pleasure is derived from the act of eating itself, and/or from the process of becoming fatter. Pleasure may be derived from specific changes to specific areas of the body.

The National Association to Advance Fat Acceptance specifically condemns feederism, claiming that the practice typically involves coercing a person to become larger. NAAFA compares this to the practice of coercing a person to become thinner and instead focuses on acceptance.
