A high-fat, moderate-protein and extremely low-carbohydrate diet is the ketogenic diet. Although the body prefers to get its energy from carbs, less than 5% of the calories on a rigorous ketogenic diet come from these sources. Here are nutritious items that you may add to your regular snacks or include in your keto-friendly snacks.

• Seafood and Fish

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, mackerel, sardines, albacore tuna, and other fatty fish, have been reported to reduce blood sugar levels and improve insulin sensitivity. Regular fish consumption has been associated with a lower chance of developing chronic diseases as well as better mental health. 

• Poultry and Meat

On the ketogenic diet, meat and poultry are regarded as basic foods. Fresh meat and poultry are low in carbohydrates and high in B vitamins as well as other vital minerals. Additionally, they're a fantastic source of high-quality protein, which may aid in maintaining muscle mass when on a very low-carb diet. 

• Veggies Low in Carbs

Nonstarchy veggies are abundant in nutrients, such as vitamin C and a number of minerals, yet low in calories and carbohydrates. They also include antioxidants, which help defend against free radicals, which harm cells. Choose non-starchy veggies with a cup serving containing no more than 8 grams of net carbohydrates. Total carbohydrates less fiber equals net carbohydrates. The appropriate vegetables include asparagus, cauliflower, broccoli, bell peppers, zucchini, and spinach.

• Eggs

Eggs are a very nutritious source of protein. Eggs may be a great keto food since they provide roughly 6 grams of protein and less than 1 gram of carbohydrates per big egg. Eggs have also been demonstrated to release chemicals that heighten feelings of satiety.

• Cheese 

Cheese is a wonderful fit for the keto snacks since it is a no carbs and is high in fat. Calcium and protein are also abundant in it. However, a 1-ounce slice of cheese has roughly 30% of the Daily Value for saturated fat, so if heart disease is a concern for you, think about portion size when enjoying cheese.

• Yogurt with Cottage Cheese

Both yogurt and cottage cheese are calcium- and protein-rich. There are just 5 grams of carbs and 12 grams of protein in five ounces of plain Greek yogurt. The same amount of cottage cheese has 18 grams of protein and 5 grams of carbs. Both calcium and protein have been demonstrated in studies to decrease hunger and increase feelings of fullness. Full-fat foods would be allowed on the ketogenic diet, and higher-fat dairy products like yogurt and cottage cheese help you feel fuller for longer.
