Wow! Low-Carb Five-Spice Beef Rub Recipe is sort of sweet and Chinese-y. I invented this for beef ribs, but there’s no law that says you can’t use it on brisket or even on a steak.
When I wrote this recipe, Splenda was widely accepted in the low-carb community. Feel free to substitute Truvia, an erythritol/monk fruit blend or erythritol/stevia blend, or whatever granular sweetener you prefer. But keep sweetness equivalence in mind. For example, the Natural Mate erythritol/stevia blend I have is double the sweetness of sugar, so I would use 1½ teaspoons (half a tablespoon). This would, of course, make for a slightly smaller yield, but the flavor should be right.
