The keto diet is a high-fat, low carbohydrate diet. It decreases blood sugar and insulin levels while shifting the body’s metabolism from carbs to fat and ketones.

what do we eat on the keto diet?

1.Fish and seafood

Because seafood is naturally strong in protein and low in carbohydrates, it is great for a keto diet. Seafood is thinner than red meat, but it is high in omega-3 and omega-6 fatty acids, which are good for you. The largest concentration of these heart-healthy fatty acids is found in these four fish.

Salmon is not only delicious, but it’s also high in omega-3 fatty acids (approx. 4,123 mg in half a fillet). It’s also high in B vitamins, vitamin D, and selenium, among other essential nutrients. Grilling or broiling this meaty fish is a great option. 

Only a thin drizzle of olive oil and a pinch of salt and pepper are required. You may also serve it with a wonderful vinaigrette, such as this Salmon with Mustard Vinaigrette.

Mackerel is the underappreciated cousin of salmon. It’s just as high in omega-3s and other nutrients as the other two, but it has a softer flavor. It goes great with fresh herbs and citrus marinades. Grilled, broiled, or pan-fried options are available.

To test out this delectable fish, here’s a great keto-friendly recipe: Sweet Peppers with Thyme in a Pan-Seared Mackerel.

Tuna is a versatile fish with a rich taste. Fresh tuna has a satisfyingly rich, flaky texture, although canned tuna is the most popular in the United States. It’s high in fatty acids and vital elements like selenium, vitamin B12, and vitamin D. Tuna steaks are delicious straight from the grill, pan-fried, or broiled. If you like tuna salad, try this recipe using fresh tuna!


Oysters are surprisingly nutrient-dense. A serving of oysters will provide your body with zinc, copper, and vitamin B12, in addition to omega-3 fatty acids. These tasty morsels can be eaten cooked or raw.

This dish for Mardi Gras Grilled Oysters is delicious and keto-friendly. On a keto diet, you can eat a lot more than just these four fish! While these four forms of seafood contain the most omega-3 fatty acids, this essential ingredient can also be found in a variety of other seafood.


Herring is a nutrient-dense medium-sized fish with a moderate flavor. Cold-smoked, pickled, or pre-cooked versions are popular. It is available in both canned and fresh form in fish markets. A medium-sized herring fillet contains 946 mg of omega-3 fatty acids, as well as vitamins B12, D, and selenium. On top of a bed of greens, try it pickled in a sour cream sauce.

2. Low carb vegetables

Lettuce is frequently used as a salad leaf. Sandwiches, burgers, and salads can all benefit from the crunch of iceberg lettuce. Lettuce is high in dietary fibre and hydrates the body.

The lettuce leaf is also high in Vitamin C, which can help boost your immune system. Lettuce is a low-carb vegetable that may be consumed guilt-free and without concern on the keto diet.

Zucchini, like lettuce, is a hydrating low-carb vegetable that you can eat guilt-free on a keto diet. It has a great flavor and may be used in salads, sandwiches, or even eaten raw. Zucchini noodles have been extremely popular recently, and they make for a fantastic low-carb supper on the keto diet. Vitamin C, A, and calcium are abundant in this vegetable.

Mushrooms, with their creamy texture, are one of the healthiest foods you can eat on a keto diet. They have a low carbohydrate, calorie, and fat content.

They have a low fiber content but are high in potassium, magnesium, zinc, and folate. You can add mushrooms to salads, make a delightful cream of mushroom soup, and sautee veggies with mushrooms. Mushrooms are a great low-carb vegetable to include in your keto diet for speedy weight loss.

Among other nutrients, asparagus is high in folate, Vitamin K, and fiber. A cup of asparagus has less than 30 calories in it. Asparagus is traditionally served alongside grilled vegetables or meat. Asparagus can also be added to sauteed veggies or omelets.

Green beans are low in calories, with only 30 calories per cup. They’re also low in carbohydrates. Fibre, Vitamin C, K, A, beta-carotene, folate, and potassium are all nutrients found in green beans. Green beans can be used in a variety of dishes, including sautéed vegetables, salads, and sabzis.

3. Cheese

If you’re trying to stick to a keto diet, goat cheese is a great option. It has no carbs, making it a perfect option to hit your macros – 1 ounce (oz) of goat cheese has 103 calories, 8 grammes of fat, 0 grammes of carbs, and 6 grammes of protein, according to the USDA (USDA).

According to Wagner, goat milk cheese has less lactose (a naturally occurring sugar in dairy) and proteins that are different from those found in cow’s milk, making it simpler to digest.

Grated Parmesan cheese is ideal for providing a salty, nutty flavor to a variety of dishes. According to the USDA, 1 tablespoon of grated cheese has 21 calories, 1.4 g of fat, 0.7 g of carbohydrates, and 1.4 g of protein.

Pro tip: When it comes to salads, make this cheese your closest buddy. Lauren Weiss, Ph.D., a keto dietitian in La Jolla, California, says, “A lot of keto dieters like Caesar salads [without croutons], and Parmesan cheese plays a huge role in enjoying them.”

(Those croutons are going to add a lot of carbs to your bowl!) When you’re on a diet, it’s easy to fall short on vegetables, so finding salads you like is crucial.

If you’re craving cheese but are on the run, these dried bite-sized slices of cheese are a tasty option. “Clients [on the keto diet] miss chips and crackers,” Dr Weiss explains. “For a high-fat snack, dip these cheese bits in guacamole.” The best part is that you won’t have to worry about keeping your cheese fresh.

Moon Cheese has an “Oh My Gouda” version with 14 g of fat, 1 g of carbohydrates, and 11 g of protein per 1-oz serving, for a total of 170 calories. Whisps, for example, has an Asiago and Pepper Jack flavour with 11 grammes of fat, 1 gramme of carbohydrates, and 12 grammes of protein per 150-calorie serving (about 23 crisps).

“Flavorful cheeses, such as smelly cheeses, provide more flavor for your buck. “They add a lot of complexity for a minimal investment,” Wagner explains. According to the USDA, one ounce of blue cheese contains 100 calories, 0.7 grams of carbohydrates, 6 grams of protein, and 8 grams of fat, making it a tasty and low-carb snack or topping for your favorite recipes.

4. Avacado

With the exception of olives and coconut, avocados have a high fat content, which is unusual in fruits. Avocados are also known as “butter pear” because of the creamy texture and rich flavor of the fruit inside, in addition to being nicknamed “alligator pear” for its black, leathery skin.

Avocado eating has been related to a number of health benefits, including:

Improved lipid profile: A systematic analysis of randomized controlled trials (RCTs) indicated that eating avocados reduced LDL cholesterol and triglyceride levels while increasing HDL levels.

Some of these changes, however, may not occur in everyone who consumes more avocados.

Reduced oxidation of LDL: In a recent study, participants with high LDL cholesterol who ate one avocado per day for five weeks saw a significant reduction in oxidized (damaged) tiny, dense LDL particles – the type linked to heart disease the most.

The nutritional profile of avocados is really good. A 100-gram (3.5-ounce) serving (half an avocado) has the following nutrients:

Natural fat (15 g)
Protein: 2 g
Total carbohydrates: 9 g, including 7 g fiber
calorie count 160
485 milligrams of potassium, or 14% of the required allowance (RDI). This is more than a medium banana would provide, yet it contains far less sugar.


Avocados are high in vitamin C, folate, vitamin B6, pantothenic acid (vitamin B5), magnesium, and vitamin E.
In addition, based on the observational, test tube, and animal research, they contain phytochemicals (“plant chemicals”) that may give health advantages. More research, however, is required to confirm these findings.

5. Eggs

Eggs are one of the world’s healthiest foods and a key component of the Keto diet. Given the tight and limited requirements of the Keto diet, egg is one such item that meets all of the requirements, including minimal carbs and high fats, as well as a high supply of protein and other necessary elements.

A large egg typically includes less than 1 gramme of carbs and less than 6 grammes of protein, making it an excellent ketogenic dietary product.

When following a Keto diet, it’s critical to consume the entire egg, as the yolk contains the majority of the nutrients. This includes the antioxidants lutein and zeaxanthin, both of which aid in eye health protection.

Despite the fact that egg yolks are regarded as a minor food group.

Eggs are high in protein and contain all of the essential amino acids. Amino acids are essential for the body’s protein synthesis.


Eggs are known to be one of the best protein sources. Protein-rich foods aid in the development of muscle mass, the sensation of fullness, the reduction of hunger sensations, and the loss of weight.

Eggs can help you curb your hunger and thus cut down on your food consumption, which is a key component of the Keto diet.


Eggs are high in Vitamin D and hence a good source of protein for persons who are vitamin deficient. Depression, prostate cancer, dementia, and cardiovascular disease are all linked to a lack of vitamin D.

Eggs contain lutein, a yellow pigment concentrated in the retina of the eye, which can help with eye disorders. It guards against macular degeneration, the most common cause of visual loss. It also shields eyes from hazardous blue light emitted by laptops, smartphones, televisions, and other electronic devices.
