They're fucking sneaky man... Often you can't tell until you start reading whether it's gunna be a ham of not. Luckily they sometimes use BBW as a keyword, or the story 'plot' focuses on the handsome man rescuing the poor girl from a family who keeps calling her fat even though she is like totes bea-you-ti-fullll she just needs a big strong (fit) man to convince her. Bonus points if he is in some kind of first responder profession or a badass tattoo artist. Fuck hams, ruining romance novels every where. Sometimes you know the description has been left vague enough so fat girls can imagine the heroine is fat too. Yuck.
