Preheat the oven to 375°F and line a baking sheet with parchment paper.
Place the ground turkey in a large mixing bowl. Add the squeezed zucchini, crushed pork rinds, oat fiber, egg, onion, garlic, salt, pepper, and parsley.
Mix everything with your hands or a spoon until the ingredients are evenly combined but not overworked.
Shape the mixture into a loaf about 8 inches long and place it on the prepared baking sheet.
Spread the sugar-free ketchup evenly over the top of the loaf.
Bake for 45 to 50 minutes until the internal temperature reaches 165°F.
Let the meatloaf rest for 10 minutes before slicing.
