Fish and Seafood

Fish is a protein-rich, carb-free food that is high in B vitamins, potassium, and selenium. Omega-3 fats, which are abundant in salmon, sardines, mackerel, albacore tuna, and other fatty fish, have been reported to reduce blood sugar levels and improve insulin sensitivity.

Low-Carb Veggie

Nonstarchy veggies are abundant in nutrients, such as vitamin C and a number of minerals, yet low in calories and carbs.They also have antioxidants, which help defend against free radicals, which harm cells. Choose non-starchy vegetables that have no more than 8 grammes of net carbohydrates per cup.


Cheese is a perfect fit for the ketogenic diet because it contains no carbohydrates and is high in fat. Calcium and protein are also abundant in it. However, a 1-ounce slice of cheese provides around 30% of the recommended daily intake of saturated fat.

Plain Greek Yogurt 

Both yoghurt and cottage cheese are calcium- and protein-rich. The only carbohydrates and protein in five ounces of plain Greek yoghurt are 5 and 12 grammes, respectively. The same amount of cottage cheese contains 18 grammes of protein and 5 grammes of carbs.


Pick heart-healthy fats like avocados, which are rich in potassium, a mineral that many Americans lack, and monounsaturated fat, which is good for your heart. 9 grammes of total carbohydrates—7 grammes of which are fiber—are present in one-half of a medium avocado.

Meat and Poultry

Protein, B vitamins, minerals, and antioxidants are all abundant in eggs. 12 grammes of protein and 0 carbs may be found in two eggs.

Nuts, Seeds and Healthy Oil
