What is Keto Diet? Have you ever wondered about the whole buzz that has been around that diet name? What are its benefits?

At Mangia Blog today, we will answer all the above and review a list of Keto Food Items to include in your daily nutrition. We will also talk a bit about how you can achieve the maximum weight loss and health results as a keto lover.

The keto diet is a high-fat, adequate-protein, low-carbohydrate diet. The diet forces the body to burn fat rather than carbs and here is how:

Normally carbs in food are converted into glucose, which is then transported around the body and is important in fueling brain function. But if little carbs remains in the diet, the liver converts fat into fatty acids and ketone bodies, the latter passing into the brain and replacing glucose as an energy source.

This is achieved by excluding high-carbohydrate foods such as starchy fruits and vegetables, bread, pasta, grains, and sugar, while increasing the consumption of foods high in fat such as nuts, cream, and butter. Most dietary fat is made of molecules called long-chain triglycerides (LCTs). However, medium-chain triglycerides (MCTs)—made from fatty acids with shorter carbon chains than LCTs—are more keto. A variant of the classic diet known as the MCT keto diet uses a form of coconut oil, which is rich in MCTs, to provide around half the calories. As less overall fat is needed in this variant of the diet, a greater proportion of carbohydrate and protein can be consumed, allowing a greater variety of food choices

Studies have found that this very low carb, high fat diet is effective for weight loss, diabetes, and epilepsy. There’s also early evidence to show that it may be beneficial for certain cancers, Alzheimer’s disease, and other diseases, too. 

Still, higher quality research on the diet is still needed to determine its long-term safety and efficacy. A keto diet typically limits carbs to 20 to 50 grams per day. While this may seem challenging, many nutritious foods can easily fit into this way of eating.

Here are some healthy foods to eat on a keto diet.

1. SEAFOOD

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

However, the carbs in different types of shellfish 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 keto diet, it’s important to account for these carbs when you’re trying to stay within a narrow range. Here are the carb counts for 3.5-ounce (100-gram) servings of some popular types of shellfish: clams: 4 grams, mussels: 4 grams, octopus: 4 grams, oysters: 3 grams, squid: 3 grams

Salmon, sardines, mackerel, and other fatty fish are very high in omega-3 fats, which have been found to lower insulin levels and increase insulin sensitivity in people who have overweight and obesity. In addition, frequent fish intake has been linked to a decreased risk of disease and improved cognitive health. The American Heart Association recommends consuming 1 to 2 seafood meals every week.

2. LOW CARB VEGGIES

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. The term “net carbs” simply refers to carbs that are absorbed by the body.

Many 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 7 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

spaghetti squash is a natural substitute for spaghetti

Here are some examples of keto-friendly vegetables to include in your eating plan.

Keto vegetable list:

  • asparagus
  • avocado
  • broccoli
  • cabbage
  • cauliflower
  • cucumber
  • green beans
  • eggplant
  • kale
  • lettuce
  • olives
  • peppers (especially green)
  • spinach
  • tomatoes
  • zucchini

3. CHEESE

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

One ounce (28 grams) of cheddar cheese provides 1 gram of carbs, 6.5 grams of protein, and a good amount of 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 less muscle mass and muscle strength loss over the course of the study than others.

Here are some cheeses that are lower in carbs for a keto diet.

Keto cheese list:

blue cheese, brie, camembert, cheddar, chevre, colby jack, cottage cheese, cream cheese, feta, goat cheese, halloumi, Havarti, Limburger, manchego, mascarpone, mozzarella, muenster, parmesan, pepper jack, provalone, romano, string cheese, Swiss

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 keto diet easier.

In addition, avocados may help improve cholesterol and triglyceride levels. A study found that participants eating one avocado per day had beneficial effects for their cardio metabolic risk factors including lower levels of LDL, which refers to bad cholester

5. MEATS AND POULTRY

Meat and poultry are considered staple foods on a keto diet. Fresh meat and poultry contain no carbs and are rich in B vitamins and several important minerals. 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.

One study in older women found that consuming a diet high in fatty meat led to HDL (good) cholesterol levels that were 5% higher than on a low fat, high 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.

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 about 6 grams of protein, making eggs an ideal food for a keto lifestyle .In addition, eggs have been shown to trigger hormones that increase feelings of fullness and satiety.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 size of LDL particles in a way that reduces the risk of heart disease.

7. COCONUT OIL

Coconut oil has unique properties that make it well suited for a keto 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 adults with obesity 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.\

8. PLAIN GREEK YOFURT 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 keto lifestyle in moderation.

A half cup (105 grams) of plain Greek yogurt provides 4 grams of carbs and 9 grams of protein. That amount of cottage cheese provides 5 grams of carbs and 11 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, or other spices for a quick and easy keto treat.

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’ve been cooked.

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.

Although all nuts and seeds are low in net carbs, the amount varies quite a bit among the different types.

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.

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.

13. UNSWEETENED COFFEE AND TEE

Coffee and tea are healthy, carb-free drinks.

They contain caffeine, which increases your metabolism and may help 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 intake have the lowest risk for 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 nonfat milk and contain high carb flavorings.

14. DARK CHOCOLATE

Dark chocolate and cocoa are delicious sources of antioxidants.

In fact, cocoa provides at least as much antioxidant activity as any other fruit, including blueberries and acai berries.

Dark chocolate contains flavanols, which may help 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, and eat in moderation.

15. 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, in vitro studies suggest that consuming olives may help prevent bone loss and decrease blood pressure, though no human trials are available yet.

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.

Ten olives (34 grams) contain 2 grams of total carbs and 1 gram of fiber. This works out to a net carb count of about 1 gram depending on the size.

To Conclude

A keto diet can be used to achieve weight loss, blood sugar management, 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 reap all the health benefits of a ketogenic diet, consume keto-friendly foods on a regular basis.
