4) Octopus
It might not be common to eat octopus, but it will provide much protein and essential vitamins and minerals every time you do. It is a delicacy and sometimes very expensive, but definitely worth it. You can eat octopus in a keto diet, but do not overdo it because it contains 4grams of carbohydrates per 100 grams serving.
100 grams of octopus meat contains a bit more than 29 grams of protein. The type of protein is also high-quality. Besides the usual vitamins and minerals, you will get a load of zinc, phosphorus, and selenium every time you eat octopus.
