Looking for a specific story

I cannot remember the title or the author, but it was a long romance that focused on soft feedism. The hero had a crush on a plump coworker who was engaged to a feeder. Her fiancée didn’t want her to work and pushed her to gain. There was a lovely scene where she and the hero tipsily look at classical art and talk about beauty standards. When the hero and she end up together, she shows up to his house with a bag full of junk food to feed to her.

It was definitely a British author, I think Jaffa cakes were mentioned several times. 😂

Does this ring a bell for anyone?
