Good to Know
Traditional brewed versions like Kikkoman or San-J keep things simple with soybeans, wheat, salt, and water, so the carb count stays low. Tamari is a smart swap if you want gluten-free, and most tamari sits in the same carb range. Sweetened styles are where the math changes: teriyaki, kecap manis, and some "sweet soy" glazes pack added sugar that can push a single tablespoon to several grams of carbs.
Is Soy Sauce Keto? The Full Answer
Soy Sauce contains 0.70g net carbs per 1 tbsp (0.80g total carbs minus 0.10g fiber). Soy sauce brings just 0.7 g net carbs per tablespoon, so a splash over stir-fried veggies or seared salmon stays easy on your daily count. Reach for the regular or tamari versions and you keep that number low while adding real savory depth.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 3% of a 20g daily carb limit. That makes Soy Sauce a reliable keto staple.
