If you haven’t been living in isolation, you must know that the ketogenic diet has become extremely fashionable recently. A diet plan consisting of mostly fats and little carbohydrates has become popular in the diet industry due to its ability to help people shed weight rapidly.

A diet plan that follows the Keto diet requires that you do not eat any carbohydrates throughout the day. For those who start the keto diet, they may observe a dramatic lowering of puffiness and the amount of water in the body.

The therapeutic benefits of the ketogenic diet have been widely shared on social media and endorsed by influential celebrities. Or is it just another hazard of diet culture? Let us find out.

Keto Diet

A keto or ketogenic diet consists of a lower amount of carbohydrates, an adequate amount of proteins, and a larger amount of fat. The majority of the diet consists of between 65% to 80% fat, with the remaining percentage being composed of protein and carbohydrates.

The objective of keto diets is to get your body to utilize fats as fuel. In the 1920s, caregivers used the ketogenic diet to provide relief for children dealing with epilepsy. This diet has gained traction as an effective way to shed pounds over the years.

Different variations of the keto diet exist. The way they ingest different food groups – carbohydrates, protein, and fat – is different.

Ketosis: The Mechanism Behind Keto Diet

When you stick to a keto diet, your metabolism switches to a ketotic state. Rather than using carbohydrates, the body utilizes fat as the main fuel for its daily operations. When you cut back on carbohydrates, your blood sugar levels start to drop.

Adipose tissue releases fatty acids that are changed into ketone bodies. Fat is used to generate ketone bodies in preference to glucose to be used as fuel by the body.

Basically, when you take away the carbs from your diet, the body will look for other sources of energy. In this case, fats burn. And this is what helps you to lose weight.

Foods to Eat During Keto Diet

The Keto diet includes 70-75% fat, 20% protein, and somewhere between 5 and 10 percent carbohydrates. Some may consume only 20 grams of carbohydrates a day in order to attain the most remarkable ketosis state.

Anything containing carbohydrates and sugars is off-limits. No carbohydrates can be found in any kind of meat or poultry, rendering them perfect for ketogenic diets. Here are some food items that are suitable for a keto diet and some snacks that you can indulge in occasionally.

1. Fatty Seafood

Salmon is a fatty fish that contains excellent amounts of omega-3s which are beneficial for heart health. Its low carb content makes it an ideal dish for a ketogenic diet.

A serving of salmon that is equivalent to 100 g has 21.6 g of protein, 5.93 g of fat, and does not have any carbohydrates. In addition to those choices, shrimp, sardines, tuna, scallops, and trout are excellent sources of high-quality protein.

Seafood like mussels, lobsters, oysters, clams, and crab are low in carbohydrates, high in lean protein, and good for a ketogenic diet. Crab meat is an example of a food containing 20 grams of protein in every 100 grams, plus 1.76 grams of fat and no carbohydrates.

2. Keto-safe Veggies

The majority of veggies are heavy in carbs, however zucchini, tomatoes, cucumbers, cauliflower, bell peppers, and squash are not as high in their carb count. Non-starchy vegetables are packed with dietary fiber and contain few carbs and calories, making them ideal for keeping your digestive system functioning properly.

Vegetables that are grown on the surface are usually the optimal food choices for a keto diet. You can include lettuce, spinach, eggplant, asparagus, and olives. A selection of spinach, lettuce, and asparagus all together weighing 100 grams will not have more than 2 grams of carbohydrates.

3. Nuts and Seeds

When on a keto diet, the top nuts to include are walnuts, pecans, almonds, hazelnuts, pine nuts, peanuts, and macadamias.

Nuts contain a lot of polyunsaturated and monounsaturated fats, but have very low amounts of carbohydrates. Macadamia nuts have a high fat content as demonstrated by their 100-gram sample size which contains nearly 76 grams of fat.

You are able to make use of sunflower, sesame, hemp, pumpkin, flax, and chia seeds as part of a ketogenic diet. Adding oil-containing seeds to your low-carb ketogenic diet can give your boring meals some extra flavor and texture without taking away from the desired fat content. Be aware not to overindulge on seeds and nuts.

4. Berries

Most fruit contains a lot of carbohydrates, however, berries are an unusual case. They have reduced amounts of carbohydrates and are high in dietary fiber.

Adding strawberries, raspberries, blackberries, and blueberries to your ketogenic diet can be a refreshing change. Despite their health benefits, blueberries should not be consumed in excess as they have the most carbohydrates of any berry.

A measurement of 100 grams of raspberries contains 5 grams of carbohydrates, while 100 grams of blueberries has12 grams of carbohydrates. You get a bonus of satisfaction for your craving for something sweet with berries.

5. Dairy and Eggs

Add more cheese to your keto meals. It’s high in fat and has fewer carbohydrates.

In addition, unless you’ve got an allergy, you can consume whole-fat yoghurts, cottage cheese, sour cream, butter, and whipping cream. Cheeses that are more challenging to eat, such as Parmesan, contain less carbohydrates than softer cheeses. Swiss cheese or semi-hard cheese are good options too.

It takes a while for your body to break down the high fat content in dairy products, which in turn helps to keep you feeling satiated for a longer period of time. As a result, it can help you snack less. Moreover, a keto diet with dairy products provides vitamin D, phosphorus, and calcium.

Eggs are the staple of the ketogenic diet. Eggs contain high levels of fats together with small amounts of carbs, and have an array of vitamins and minerals, including protein, and antioxidants.

Therefore, an individual large egg provides 6 grams of protein and no more than one gram of carbohydrates. Entire eggs, the yellow and the white, are the primary sources of fat and protein in morning meals that are keto-friendly.

6. Oils and Fats

Most of the energy consumed in a keto diet is derived from fats, accounting for 70%-80%. Plant-based oils are the most unadulterated form of fat as they have no carbohydrates, making them essential for the ketogenic lifestyle. A low-carb diet needs oil for preparing, saucing, and frying.

Extra virgin olive oil is composed of 14 grams of fat and has no carbohydrates when a single tablespoon is used. Another higher fat option is coconut oil. This foodstuff has a lot of saturated fat and can be employed in recipes that are related to the ketogenic diet.

Ghee is famous in Indian households. Organic cow ghee is a beneficial kind of fat and compatible with the ketogenic diet. Butter, avocado oil, and animal fats are usable for baking, pan-frying, and deep-frying, among other cooking methods. These three foods are worth consideration.

7. Beverages 

It is permissible to drink unflavored coffee, green tea, black tea, and plant-based milks. Occasionally, it is possible to relish sweeteners such as sucralose and stevia.

Consume strong alcoholic beverages, sparkling wine, and dry wine in moderation. Even though diet sodas meet the criteria for being a part of the ketogenic diet, they are not a beneficial option for your health. An alternative is carbonated water which has no carbohydrates.

8. Snacks

Several pieces of bacon, a handful of olives, and a piece of cheese can be the perfect meal if you’re following a low-carb diet. You can also treat yourself to some small amounts of nuts, for example, Brazil nuts, pecans, and macadamia nuts.

Veggies such as celery, cucumber, and carrot sticks, served with a dip of your choice, are a popular snack on the ketogenic diet, due to their low carb content. The dip is generally paired with something that is high in fat like a sauce, sour cream, or cream cheese. Berries and cream prepared with no sweeteners or sugar makes a pleasant snack that is low in carbs.

Follow the Ketogenic Diet

There are several 
types of keto, but essentially, to achieve a state of 
ketosis, you have to severely reduce the amount of carbs you eat. (You can use 
a ketogenic calculator to create a custom food plan.)
Data suggest the average American man age 20 or older consumes 46.4 percent of his daily calories from carbs, and the average American woman older than 20 consumes 48.2 percent of her daily calories from carbs.
But in the classic ketogenic diet, which was originally used to manage seizure disorders, 80 to 90 percent of calories come from fat, 5 to 15 percent come from protein, and 5 to 10 percent come from carbohydrates.

A contemporary variation of the ketogenic diet permits one to consume protein in a more unrestricted way, around 20 to 30 percent of their overall daily calorie intake, while maintaining the same limits on carbs.

The most recent adaptation of the ketogenic diet has the intention of aiding individuals with achieving weight reduction, controlling weight, and improving their sports aptitude.

Health Risks of the Keto Diet

You May Suffer Fatigue and Other Symptoms as a Result of the Keto Flu

One of the most common side effects of starting the ketogenic diet is “
keto flu.” This term describes the often unpleasant, fatigue-inducing symptoms that occur as the body adjusts from a high-carbohydrate to a 
low-carbohydrate diet.
During
 
keto flu, the body’s stored glucose begins depleting, and the body starts adapting to producing and utilizing ketones as energy.
Symptoms of the keto flu include headache, fatigue, dizziness, sleep problems, heart palpitations, cramps, and diarrhea. These side effects usually diminish and resolve in about two weeks.
But to lessen the effects of any discomfort, simply consider slowly transitioning onto a ketogenic diet rather than rushing to change your eating habits.
By gradually lowering your carbohydrate intake and gradually increasing your intake of dietary fat, you can transition with less negative impact and potentially prevent the keto flu altogether.
You Could Develop Dangerous Nutrient Deficiencies

Eliminating food groups can be problematic. Marie Spano, a dietitian focused on sports nutrition in Atlanta, emphasizes the importance of carefully planning a ketogenic diet. If done so incorrectly, it may put one at risk of developing deficiencies in calcium, vitamin D, magnesium, and folic acid in the long-term.

You May Harm Your Heart With the Diet’s Emphasis on Animal Fat and Protein

Reliance on a diet rich in animal fats and proteins may also have a negative impact on heart health, research shows.

“This diet is not for anyone who is at risk of developing cardiovascular disease or who has already been diagnosed with it,” Spano cautions. 
This means that if you have risk factors for heart disease — such as elevated 
cholesterol
high blood pressure (hypertension), or a strong family history of the disease — you should use caution when following this diet.
The diet’s heavy reliance on fat, especially saturated fat, can raise
 
cholesterol levels, further increasing your chances of developing heart disease in the future.
A 2019 position statement from the National Lipid Association Nutrition and Lifestyle Task Force noted that research has found low-carb and very low carb plans (which keto fits into) have mixed effects on blood cholesterol levels, with some studies finding that these diets raise cholesterol.

You May Experience Dangerous Low Blood Sugar if You Have Diabetes

For any individual with diabetes, discussing dietary changes — especially those as dramatic as the ones the ketogenic diet requires — with your healthcare team is essential.
Because carbohydrates are broken down into glucose in the blood, cutting carbohydrates from your diet could cause levels to crash rapidly depending on your current medication regimen.
Such a change may require significant adjustments to medication and insulin to prevent dangerous side effects such as low blood sugar, called 
hypoglycemia.

You May Experience Weight Cycling and Negative Effects on Your Metabolism

A major worry about the ketogenic diet is whether it can be followed consistently in the long run. Apart from impacting physical health, this is one of the major issues. Adhering to and sustaining this dietary regimen is quite challenging. Dr. Mohr states that following the requirements of compliance can be difficult as it is so constraining.

Following a strict
 
diet for weight loss
 and then quickly reverting to old habits when the dietary changes are too restrictive can lead to what is known as weight cycling, or yo-yo dieting.
Gaining and losing the same weight over and over is associated with poorer cardiovascular health, especially among premenopausal women, according to a study in
 
Preventive Medicine Reports published in December 2019.
Health Benefits of the Keto Diet

You May See Improvements in Your Athletic Performance 

For athletes, research on the keto diet highlights potential improvements in athletic performance, especially when it comes to endurance activities.
An article in the
 
British Journal of Sports Medicine
 found that ketogenic-type diets allowed endurance athletes to rely mostly on stored fat for energy rather than having to refuel with 
simple carbohydrates during endurance training and competition, and saw improved recovery times.
That said, a review published in October 2020 in
 
Sports concluded that while the keto diet may help athletes reduce their weight and body fat, there is no conclusive evidence that the method of eating improves or harms health and performance.

You Could Lose Weight Fast — but Not Necessarily More Than You’d Lose on Other Diets

If you’re looking to lose weight, one benefit the ketogenic diet may offer is appetite suppression. A review of this form of eating suggests it may help decrease appetite, but how this actually happens needs to be studied further.
Very low calorie ketogenic diets may help people who are overweight or have obesity reduce their
 
BMI, decrease the circumference of their waist, and lower levels of
 
A1C, total cholesterol,
 
triglycerides, and blood pressure, notes a review and meta-analysis published in March 2020 in
 
Reviews in Endocrine and Metabolic Disorders
.

In regards to weight reduction – one of the strongest reasons for people to try a ketogenic diet – the advantages of the keto diet may not be really different from other diet regimes. Spano states that this specific diet cannot give any kind of miraculous advantage when it comes to weight loss. The ketogenic diet could potentially be beneficial for those who wish to shed a few pounds, in the same manner as other diets have proven to, by means of limiting food choices in order to ultimately consume fewer calories.

Mohr agrees. “Cutting so many carbohydrates is a big reduction in calories,” he says, adding that this effect will lead to a loss of 
water weight up front, “which is why people like the immediate response of weight loss that comes from this type of diet.”
That said, the calorie reduction isn’t always the case, as it can be easy to consume more calories overall if you’re eating more calorie-dense foods (namely fat).
One small study published in February 2021 in
 
Nature Medicine
 found that people ate almost 700 fewer calories per day on a plant-based low-fat diet compared with a low-carb one consisting of mostly animal fats.

You May See Better Blood Glucose Control if You Have Type 2 Diabetes

For individuals with diabetes, adapting a very low carbohydrate diet, such as the ketogenic diet, may offer some benefits when it comes to glucose management.
For instance, a previous review found that dietary restriction of carbohydrates may reduce or eliminate the need for medication in individuals with type 2 diabetes
