I assume some sort of zero \ low sugar kind? All Gold won't work as it is like syrup (have not read up on their lite version though)
That recipe is a typical barbecue basting. Almost all of them have sugar of some sort - either brown sugar, or tomato sauce, or both. Even Asian style bastings usually have sugar.
So, I suppose what would be important is how much sugar you would be ingesting in total? If there is not that much sugar added, then its okay.
If you wanted a no sugar added recipe, you could do something like this:
Chopped tomatoes, chopped onions, apple cider vinegar, paprika, cumin, oregano, garlic, salt. Simmer until everything has melted together and is thick. Could be a while, like an hour. Add the spices in the last 10 minutes only. You'll have to do it by taste. Also remember that sugar will add as a thickening agent, so it might not get that thick without it.
Alternatively, you could do a Asian dipping sauce. It will never be thick enough to be a basting, but maybe it doesn't need to. Try finely chopping coriander and chilli, and adding soy sauce, fish sauce and possibly a little sesame oil. Heat that up to get the flavours to mingle. It will be very salty though. You could add rice vinegar for a bit of acidity, or possibly even dilute it with water.
Experiment!
