Looping over a query result and accessing a related model on each element runs a separate query per row (N+1). Eager load the relationship upfront.

Incorrect

<?php
$posts = Post::all();
foreach ($posts as $post) {
    echo $post->author->name;
}

<?php
$posts = Post::with('author')->get();
foreach ($posts as $post) {
    echo $post->author->name;
}

Eager load relationships accessed in the loop with with() to collapse them into one extra query.
