I would suggest 'Pet Sematary' by Stephen King. While it's more of a horror in general, it has body horror aspects especially when dealing with the resurrected dead and how their bodies are not quite right. It's a well - written book that can ease beginners into the idea of body horror. Also, 'The Girl with All the Gifts' has some body horror elements as it deals with the nature of the 'hungries' and their abnormal physical states.
For beginners, 'The Strange Case of Dr. Jekyll and Mr. Hyde' is a good start. It's not as extreme as some modern body horror but still has the concept of the body changing in a disturbing way. Another option could be 'The Wasp Factory' by Iain Banks. It has some body - horror elements that are introduced gradually and are not overly graphic for those new to the genre.
A good beginner - friendly fictional body horror book is 'The Hunger' by Alma Katsu. It combines historical fiction with body horror elements. The slow decay and transformation of the characters due to a mysterious force is presented in a way that is not too intense for those new to body horror. And 'The Shining' by Stephen King also has some body horror undertones, especially when it comes to the visions and the state of the characters' minds and bodies as they are affected by the haunted hotel.
