Gluttony is the inability to resist one's appetite, and is one of the Seven Deadly Sins. Today it is most associated with overeating, but in Medieval times, drunkenness was considered a prominent form of gluttony (this might explain why the punishment for gluttons in Dante's Inferno is eternal rain).
Lesbianism and obesity
The Apostle Paul wrote in the book of Romans, "For this reason God gave them over to degrading passions; for their women exchanged the natural function for that which is unnatural, and in the same way also the men abandoned the natural function of the woman and burned in their desire toward one another, men with men committing indecent acts and receiving in their own persons the due penalty of their error." (Romans 1:26-27).
Concerning lesbianism and obesity, in April of 2007, the American Journal of Public Health analyzed data from 2002 National Survey of Family Growth and the data suggested that American lesbian women were 2.69 times more likely to be overweight and 2.47 times more likely to be obese than all other female sexual orientation groups.  The abstract for this study indicated that "lesbians are at greater risk for morbidity and mortality linked to overweight and obesity." 
In 2009, the PubMed article abstract for the Polish psychiatry journal Psychiatria Polska article Body Image in Homosexual Persons declared:
|“||Homosexual women are less concentrated on physical appearance and more satisfied with their bodies while being more tolerant to obesity.... For lesbian women the ideal body image is more massive than for heterosexual women.||”|
|“||And - oh heck, I'll admit it - aesthetics have value, too! As a woman, I may not be as focused on looks as men are predisposed to be, but I sure am tired of seeing so many queer ladies out there who are way past 200 pounds. Way, way past. Sorry, but no amount of "fat acceptance" is going to make that a pleasant sight - gay, straight, butch, femme, male or female.||”|
