Creating mulitple loops in a sub-category page

I figured this out on my own. I use the code below and duplicated it as many times as I needed without any issues so far. If anyone thinks this is incorrect than please comment. I was not using the main loop anywhere else on this page and used WP_Query.

<ul class="subcats-list">
<?php
$weightloss = new WP_Query();
$weightloss->query('showposts=5');

while ($weightloss->have_posts()) : $weightloss->the_post(); ?>
    <li><a href="https://wordpress.stackexchange.com/questions/13327/<?php the_permalink() ?>" rel="bookmark"><?php the_title(); ?></a></li>
<?php endwhile; ?>

 </ul><!-- subcat -->
