16 Foods That Are Allowed  For a Ketogenic Diet

The Ketogenic diet has built in popularity of the past year or so, and really there is no surprise why this has happened

Being a low carb intake type diet there is a lot of evidence, including scientific studies, that show that linking this with a high fat diet has great benefits for weight loss. But the benefits of a Ketogenic diet are not limited to weight loss, work has been done that demonstrates the benefits of this type of diet to treat diseases associated with mental health, diabetes, and some cancers. In fact as early as 1924, this type of diet was used to manage Epilepsy, with some success.

I found the most excellent article written by Franziska  on the foods you can eat while on a ketogenic diet that shows the large range of food types available for this type of diet.  She lists 16 food types, some examples listed below may surprise you – Coffee, Dark Chocolate, Cream………. I have used this list to get an idea of what foods I can eat.

It is a long article but a very good one and certainly worth a read if you have been considering, or even if you have started on your Keto Diet journey.

Franziska mentions that this diet limits the amount of carbs consumed to 20-50 grams per day which may sound a bit alarming to some people, but she  shows there are many good nutritious foods that qualify for use with this diet.

The List of Pro-Ketogenic Foods

1. Seafood

Fish and shellfish are very keto-friendly foods. Salmon is rich in Omega 3 and like other fish is rich in B vitamins, potassium and selenium, yet virtually carb-free

The carbs in different types of shellfish, however, vary. For instance, while shrimp and most crabs contain no carbs, other types of shellfish do.

While these shellfish can still be included on a ketogenic diet, it’s important to account for these carbs when you’re trying to stay within a narrow range.

Frequent fish intake has been linked to a decreased risk of disease and improved mental health.

Aim to consume at least two servings of seafood weekly.

SUMMARY: Many types of seafood are carb-free or very low in carbs. Fish and shellfish are also good sources of vitamins, minerals and omega-3s.

2. Low-Carb Vegetables

Non-starchy vegetables are low in calories and carbs, but high in many nutrients, including vitamin C and several minerals.

Vegetables and other plants contain fiber which your body doesn’t digest and absorb like other carbs.

Therefore, look at their digestible (or net) carb count, which is total carbs minus fiber.

Most vegetables contain very few net carbs. However, consuming one serving of “starchy” vegetables like potatoes, yams or beets could put you over your entire carb limit for the day.

The net carb count for non-starchy vegetables ranges from less than 1 gram for 1 cup of raw spinach to 8 grams for 1 cup of cooked Brussels sprouts .

Vegetables also contain antioxidants that help protect against free radicals, which are unstable molecules that can cause cell damage .

What’s more, cruciferous vegetables like kale, broccoli and cauliflower have been linked to decreased cancer and heart disease risk .

Low-carb veggies make great substitutes for higher-carb foods. For instance, cauliflower can be used to mimic rice or mashed potatoes, “zoodles” can be created from zucchini and spaghetti squash is a natural substitute for spaghetti.

SUMMARY: The net carbs in non-starchy vegetables range from 1–8 grams per cup. Vegetables are nutritious, versatile and may help reduce the risk of disease.

3. Cheese

Cheese is both nutritious and delicious.

There are hundreds of types of cheese. Fortunately, all of them are very low in carbs and high in fat, which makes them a great fit for a ketogenic diet.

One ounce (28 grams) of cheddar cheese provides 1 gram of carbs, 7 grams of protein and 20% of the RDI for calcium.

Cheese is high in saturated fat, but it hasn’t been shown to increase the risk of heart disease. In fact, some studies suggest that cheese may help protect against heart disease

Cheese also contains conjugated linoleic acid, which is a fat that has been linked to fat loss and improvements in body composition.

In addition, eating cheese regularly may help reduce the loss of muscle mass and strength that occurs with aging.

A 12-week study in older adults found that those who consumed 7 ounces (210 grams) of ricotta cheese per day experienced increases in muscle mass and muscle strength over the course of the study.

SUMMARY: Cheese is rich in protein, calcium and beneficial fatty acids, yet contains a minimal amount of carbs.

4. Avocados

Avocados are incredibly healthy.

3.5 ounces (100 grams), or about one-half of a medium avocado, contain 9 grams of carbs.

However, 7 of these are fiber, so its net carb count is only 2 grams.

Avocados are high in several vitamins and minerals, including potassium, an important mineral many people may not get enough of. What’s more, a higher potassium intake may help make the transition to a ketogenic diet easier.

In addition, avocados may help improve cholesterol and triglyceride levels.

In one study, when people consumed a diet high in avocados, they experienced a 22% decrease in “bad” LDL cholesterol and triglycerides and an 11% increase in “good” HDL cholesterol.

SUMMARY: Avocados contain 2 grams of net carbs per serving and are high in fiber and several nutrients, including potassium. In addition, they may improve heart health markers.

5. Meat and Poultry

Meat and poultry are considered staple foods on a ketogenic diet.

Fresh meat and poultry contain no carbs and are rich in B vitamins and several minerals, including potassium, selenium and zinc.

They’re also a great source of high-quality protein, which has been shown to help preserve muscle mass during a very low-carb diet.

It’s best to choose grass fed meat, if possible. That’s because animals that eat grass produce meat with higher amounts of omega-3 fats, conjugated linoleic acid and antioxidants than meat from grain-fed animals.

SUMMARY: Meat and poultry do not contain carbs and are rich in high-quality protein and several nutrients. Grass-fed meat is the healthiest choice.

6. Eggs

Eggs are one of the healthiest and most versatile foods on the planet.

One large egg contains less than 1 gram of carbs and fewer than 6 grams of protein, making eggs an ideal food for a ketogenic lifestyle. In addition, eggs have been shown to trigger hormones that increase feelings of fullness and keep blood sugar levels stable, leading to lower calorie intakes for up to 24 hours. It’s important to eat the entire egg, as most of an egg’s nutrients are found in the yolk. This includes the antioxidants lutein and zeaxanthin, which help protect eye health.

Although egg yolks are high in cholesterol, consuming them doesn’t raise blood cholesterol levels in most people. In fact, eggs appear to modify the shape of LDL in a way that reduces the risk of heart disease.

SUMMARY: Eggs contain less than 1 gram of carbs each and can help keep you full for hours. They’re also high in several nutrients and may help protect eye and heart health.

7. Coconut Oil

Coconut Oil has unique properties that make it well suited for a ketogenic diet.

To begin with, it contains Medium Chain Triglycerides (MCTs). Unlike long-chain fats, MCTs are taken up directly by the liver and converted into ketones or used as a rapid source of energy.

In fact, coconut oil has been used to increase ketone levels in people with Alzheimer’s disease and other disorders of the brain and nervous system.

The main fatty acid in coconut oil is lauric acid, a slightly longer-chain fat. It has been suggested that coconut oil’s mix of MCTs and lauric acid may promote a sustained level of ketosis.

What’s more, coconut oil may help obese adults lose weight and belly fat. In one study, men who ate 2 tablespoons (30 ml) of coconut oil per day lost 1 inch (2.5 cm), on average, from their waistlines without making any other dietary changes.

For more information about how to add coconut oil to your diet, read this article.

SUMMARY: Coconut oil is rich in MCTs, which can increase ketone production. In addition, it may increase metabolic rate and promote the loss of weight and belly fat.

8. Plain Greek Yogurt and Cottage Cheese

Plain Greek yogurt and cottage cheese are healthy, high-protein foods.

While they contain some carbs, they can still be included in a ketogenic lifestyle.

5 ounces (150 grams) of plain Greek yogurt provides 5 grams of carbs and 11 grams of protein. That amount of cottage cheese provides 5 grams of carbs and 18 grams of protein.

Both yogurt and cottage cheese have been shown to help decrease appetite and promote feelings of fullness.  Either one makes a tasty snack on its own.

However, both can also be combined with chopped nuts, cinnamon and optional sugar-free sweetener for a quick and easy keto treat.

SUMMARY: Both plain Greek yogurt and cottage cheese contain 5 grams of carbs per serving. Studies have shown that they help reduce appetite and promote fullness.

9. Olive Oil

Olive Oil provides impressive benefits for your heart.

It’s high in oleic acid, a monounsaturated fat that has been found to decrease heart disease risk factors in many studies.

In addition, extra-virgin olive oil is high in antioxidants known as phenols. These compounds further protect heart health by decreasing inflammation and improving artery function.

As a pure fat source, olive oil contains no carbs. It’s an ideal base for salad dressings and healthy mayonnaise.

Because it isn’t as stable as saturated fats at high temperatures, it’s best to use olive oil for low-heat cooking or add it to foods after they have been cooked.

SUMMARY: Extra-virgin olive oil is high in heart-healthy monounsaturated fats and antioxidants. It’s ideal for salad dressings, mayonnaise and adding to cooked foods.

10. Nuts and Seeds

Nuts and seeds are healthy, high-fat and low-carb foods.

Frequent nut consumption has been linked to a reduced risk of heart disease, certain cancers, depression and other chronic diseases. Furthermore, nuts and seeds are high in fiber, which can help you feel full and absorb fewer calories overall.

The following nuts are ideal for a Keto type diet:

Almonds,  Brazil nuts, Cashews,:  Macadamia nuts,  Pecans,  Pistachios,  Walnuts,  Chia seeds, Flaxseeds, Pumpkin seeds, Sesame seeds

SUMMARY: Nuts and seeds are heart-healthy, high in fiber and may lead to healthier aging. They provide 0–8 grams of net carbs per ounce.

11. Berries

Most Fruits are too high in carbs to include on a ketogenic diet, but berries are an exception.

Berries are low in carbs and high in fiber.

In fact, raspberries and blackberries contain as much fiber as digestible carbs.

These tiny fruits are loaded with antioxidants that have been credited with reducing inflammation and protecting against disease.

Here are some berries that fit in nicely with a keto diet:

Blackberries, Blueberries,  Raspberries,  Strawberries.

 SUMMARY: Berries are rich in nutrients that may reduce the risk of disease. They provide 5–12 grams of net carbs per 3.5-ounce serving.

12. Butter and Cream

Butter and cream are good fats to include on a ketogenic diet. Each contains only trace amounts of carbs per serving.

For many years, butter and cream were believed to cause or contribute to heart disease due to their high saturated fat contents. However, several large studies have shown that, for most people, saturated fat isn’t linked to heart disease.

In fact, some studies suggest that a moderate consumption of high-fat dairy may possibly reduce the risk of heart attack and stroke .

Like other fatty dairy products, butter and cream are rich in conjugated linoleic acid, the fatty acid that may promote fat loss.

SUMMARY: Butter and cream are nearly carb-free and appear to have neutral or beneficial effects on heart health, when consumed in moderation.

13. Shirataki Noodles

Shirataki noodles are a fantastic addition to a ketogenic diet.

They contain less than 1 gram of carbs and 5 calories per serving because they are mainly water.

In fact, these noodles are made from a viscous fiber called glucomannan, which can absorb up to 50 times its weight in water (75).

Viscous fiber forms a gel that slows down food’s movement through your digestive tract. This can help decrease hunger and blood sugar spikes, making it beneficial for weight loss and diabetes management.

Shirataki noodles come in a variety of shapes, including rice, fettuccine and linguine. They can be substituted for regular noodles in all types of recipes.

SUMMARY: Shirataki noodles contain less than 1 gram of carbs per serving. Their viscous fiber helps slow down the movement of food through your digestive tract, which promotes fullness and stable blood sugar levels.

14. Olives

Olives provide the same health benefits as olive oil, only in solid form.

Oleuropein, the main antioxidant found in olives, has anti-inflammatory properties and may protect your cells from damage

In addition, studies suggest that consuming olives may help prevent bone loss and decrease blood pressure.

Olives vary in carb content due to their size. However, half of their carbs come from fiber, so their digestible carb content is very low.

A one-ounce (28-gram) serving of olives contains 2 grams of total carbs and 1 gram of fiber. This works out to a net carb count of 1 gram for 7–10 olives, depending on their size .

SUMMARY: Olives are rich in antioxidants that may help protect heart and bone health. They contain 1 gram of net carbs per ounce.

15. Unsweetened Coffee and Tea

Coffee and tea are incredibly healthy, carb-free drinks.

They contain caffiene, which increases your metabolism and may improve your physical performance, alertness and mood 

What’s more, coffee and tea drinkers have been shown to have a significantly reduced risk of diabetes. In fact, those with the highest coffee and tea intakes have the lowest risk of developing diabetes.

Adding heavy cream to coffee or tea is fine, but stay away from “light” coffee and tea lattes. These are typically made with non-fat milk and contain high-carb flavorings.

SUMMARY: Unsweetened coffee and tea contain no carbs and can help boost your metabolic rate, as well as physical and mental performance. They can also reduce your risk of diabetes.

16. Dark Chocolate and Cocoa Powder

Dark chocolate and cocoa are delicious sources of antioxidants.

In fact, cocoa has been called a “super fruit,” because it provides at least as much antioxidant activity as any other fruit, including blueberries and acai berries.

Dark chocolate contains flavanols, which may reduce the risk of heart disease by lowering blood pressure and keeping arteries healthy

Somewhat surprisingly, chocolate can be part of a ketogenic diet. However, it’s important to choose dark chocolate that contains a minimum of 70% cocoa solids, preferably more.

One ounce (28 grams) of unsweetened chocolate (100% cocoa) has 3 grams of net carbs. The same amount of 70–85% dark chocolate contains up to 10 grams of net carbs.

SUMMARY: Dark chocolate contains 3–10 grams of net carbs per ounce, is high in antioxidants and may help reduce the risk of heart disease.

The Bottom Line

A ketogenic diet can be used to achieve weight loss, blood sugar control and other health-related goals.

Fortunately, it can include a wide variety of nutritious, tasty and versatile foods that allow you to remain within your daily carb range.

To get all the health benefits of a ketogenic diet, consume these 16 foods on a regular basis.
