Hmm, how to explain... "Goes" doesn't mean traveling here, it means... That is how the saying is said? That's how the saying goes. That's how the saying is said. That is how the saying is read. The old saying:"you are what you eat," seems like an unfinished thought

"Goes" is used to indicate that something is commonly said or believed. In this case, "goes" means that the saying "You are what you eat" is a well-known saying that is often repeated. Yes, you can write "The old saying: 'You are what you eat'" to introduce the saying. Alternatively, you could also write "As the old saying goes, 'You are what you eat'" to indicate that the saying is well-known. Thank you for allowing me to participate in the post.
