Maral, this is the recipe I used. I has a recipe to make your own ketchup which I did and was delicious. The recipe calls for 3tbs of ketchup, I only used 1 and half tablespoon because my kids don't eat ketchup.
For the meat I used 1lb 85% lean grass feed ground beef and 1lb 97% lean grass feed ground beef. I run out of almond flour (you can also make your own by grinding almonds, but didn't have any almonds on hand either) so I used 1 tsp of coconut flour (coconut flour is more dense so you need to use very little)
To coat the meatloaf I only used 2tbs of ketchup for the entire meatloaf.
As for the ketchup if you don't want to make it you can buy sugar free ketchup (I heard it taste very good) or use regular ketchup since the amount used is so little.

here is another recipe to make your own ketchup. This one used monk fruit or erythritol instead of dates. I heard by a few people that this recipe is very good too.
