Preheat the oven to 350 degrees and lightly grease a loaf pan.
In a large bowl, combine the ground beef, crushed pork rinds, egg, diced onion, minced garlic, Worcestershire sauce, salt, and black pepper.
Mix the ingredients with your hands until just combined, taking care not to overwork the meat.
Transfer the mixture to the prepared loaf pan and press it into an even shape.
Spread the sugar-free ketchup evenly over the top of the loaf.
Bake for 55 to 60 minutes, or until the internal temperature reaches 160 degrees.
Remove from the oven and let the meatloaf rest for 10 minutes before slicing.
