- Chicken, turkey, duck, and goose
- Veal and lamb
- Game meats like venison and rabbit
- Organ meats like liver, sweetbreads, and tripe
Even processed meats can come with zero carbs, but be sure to read the label prior to adding them to the cart as some have marinades or rubs that contain sugar. This can cover easy-to-make foods like hot dogs, sausages, ham, bacon, deli meats, and even canned meats that are great in a pinch. Snacks like dried meats or jerky sticks are also typically carb-free.
Seafood Is Ultra-Low Carb
While on the topic of main courses that contain zero carbs, seafood is another great option that can serve as the star of your meal. Seafood typically has no carbs, whether it is fresh or canned. Even the smoked varieties are often zero carb, but you should read the label just as carefully as you did with the processed meats to ensure that they do not impact your ketosis due to added ingredients like fillers and sugars.
Fish is a great way to supplement your diet and make it more well-rounded. According to plenty of research studies, it contains antioxidants, lowers inflammation, promotes wound healing, and protects both brain and heart health.  Canned tuna, salmon, mackerel, oysters, clams, and mussels are all great choices and make easy snacks and lunches. Fresh seafood, like scallops, shrimp, cod, salmon, trout, sea bass, and crab are also zero carb foods.
Herbs and Seasoning
Have no fear: just because you are sticking to a keto diet does not mean that your food has to be flavorless. Herbs and spices, like cumin, coriander, oregano, thyme, curry powder, cinnamon, turmeric, and cayenne, are typically considered zero-carb foods though some may have very small traces of carbs. Sugar-free hot sauces also fall into the category of zero carb foods.
Fats and Oils Are the Original Zero Carb Foods
