No Carbohydrate Diet

Take a moment and imagine cutting your carbohydrate intake by 90 percent. It sounds incredibly challenging but it is still possible.

Now imagine following a diet without carbohydrates, such as pasta, bread, legumes, baked goods, sweets and even fruits and vegetables.

For many, the idea of ​​a low carb diet, let alone a diet without carbohydrates at all, probably seems like a cruel form of torture.

Unlike the high-carbohydrate and sugar-addicted diets that most people in the industrialized nations consume today, diets without carbohydrates tend to cause rapid weight loss by reducing foods such as grains, fruits and Sweeteners

Cutting these sources of carbohydrates from your diet changes the type of macronutrients your body uses as fuel.

Each carbohydrate / low carb diet is a bit different, but it drastically reduces glucose (sugar) intake over several phases, resulting in a diet that maintains carbohydrates at about 20-50 net grams or even less up to date.

Some people who follow a diet almost free of carbohydrates consume up to 80 percent to 95 percent of their total calories from fats and proteins, especially from things like oil, fatty cuts of meat and butter.

Although it is very difficult to eat alongside carbohydrates for a prolonged period, when done in the short term and in a healthy way, low carb diets can be beneficial for the right people.

Reduced carbohydrate diets, including the ketogenic diet, have well-documented health benefits, including helping to treat seizures or epilepsy, obesity, sugar dependence for energy, and common risk factors for diabetes. / or the metabolic syndrome.

While the results of the study are mixed in general, certain large studies have found that low-carbohydrate diets tend to be more effective for short-term weight loss than low-fat diets.

And in general terms, the lower the carbohydrate diet, the more likely it is to result in very rapid weight loss, especially for those struggling with obesity.

On the other hand, carbohydrates are necessary for more than energy: they also give us fiber and are found in plant foods that contain essential nutrients, such as antioxidants.

Studies show that low-carbohydrate diets result in improved weight loss and health markers, and almost everyone knows someone who has successfully tried it.

History of the diet without carbohydrates

Dozens of different diets that are very low in carbohydrates have gained the attention of researchers and dieters in recent decades.

Diets without carbohydrates such as the ketogenic diet were originally designed for patients with epilepsy by researchers at Johns Hopkins Medical Center, as it was discovered that carbohydrate reduction and fasting helped to improve the number of seizures patients had.

Since its inception, the ketogenic diet has been linked to benefits such as protection against Alzheimer’s disease and reduced insulin-related disorders (such as polycystic ovary syndrome or diabetes) according to many studies.

In the 1990s, low-carbohydrate diets became popular for weight loss when Dr. Robert Atkin published his book “Dr. New dietary revolution of Atkins “.

Surveys show that in the late 1990s and early 2000s, in the United States, up to 18 percent of the adult population used a type of low-carbohydrate diet or another at the peak of their popularity to lose weight. weight.

Since then, dietary theories such as the Paleo diet, which reduce foods such as sugar and cereals, have reversed the mania of the low-carbohydrate diet.

The Paleo diet is now one of the most popular diets in the world, while the ketogenic diet also (commonly together with intermittent fasting) also continues to gain notoriety.

What is a diet without carbohydrates? It’s possible?

Although it is comparable to the ketogenic diet, a diet that severely limits carbohydrate intake and focuses on healthy sources of fat and protein, a carbohydrate-free diet completely eliminates carbohydrate intake.

Even foods that have small amounts of carbohydrates are prohibited in this restrictive diet.

While it may have health benefits similar to low-carbohydrate and ketogenic diets, it also comes with a different set of risks and challenges, and must be done with great care to avoid adverse side effects.

There is a good chance that you have heard of low-carbohydrate diets such as the Atkins diet or the ketogenic diet. These diets tend to be high in fats and proteins, but low in carbohydrates, such as fruits, vegetables, grains and starches.

The carbohydrate-free diet plan takes this concept one step further by eliminating all foods that contain carbohydrates and filling the diet with protein and fat exclusively.

This means that you eat a lot of meat and fat and do not have fruits, vegetables, whole grains or sweets.

This is because carbohydrates are found in almost all types of foods, even if only small amounts are involved. While there are vegetables low in carbohydrates, for example, there are no vegetables without carbohydrates that are completely free of carbohydrates.

Although theoretically you can eat very close to no carbohydrate, such as eating only things like meat, oils or lard, this is not exactly a very healthy way to eat.

Most diets that are very low in carbohydrates include at least some plants for fiber and essential nutrients, with an emphasis on the lowest carbohydrates such as leafy green vegetables or broccoli.

Unlike most weight loss diets that are generally based on calorie counting and / or strict portion control, diets without carbohydrates result in weight loss by focusing primarily on reducing foods that contain carbohydrates.

Most people care more about “net carbs” than total carbohydrates, which take into account the amount of fiber a food has.

Since fiber is not taken into account for net grams of carbohydrates (the net carbohydrates are the amount of carbohydrates left when the fiber grams are subtracted from the total carbohydrate), you can eat as much fiber as you want from vegetables without starch. you keep carbohydrates at around 5 percent total and lower calories

Eating plenty of low-carb vegetables will fill it and keep it consuming less than 20-50 grams of net carbohydrates per day.

Some carbohydrate sources that are restricted in a carbohydrate-free diet include (but are not limited to):

Fruits.
Vegetables.
Legumes, including beans, peas and peanuts.
Grains, such as pasta, bread, rice and oats.
Dairy products.
Sugar and sugary drinks such as soda or juice.
Condiments such as ketchup, salad dressing or sauces.
Nuts and seeds.
Cookies and chips.
Cakes, cookies and sweets.

How does a low carb diet work?

To help you understand the benefits and potential risks of diets without carbohydrates, here’s how carbohydrate digestion and fat burning work.

Research suggests that for those who lose weight while reducing carbohydrates, they are likely to consume fewer calories in general and feel full due to adequate intake of protein and fat.

Proteins and healthy fats tend to be very satisfying, killing most sugar / carbohydrate cravings.

Another reason why diets without carbohydrates improve weight loss is due to the possibility of going into “ketosis,” which means changing the body to the mode of burning fat instead of burning glucose.

It is often necessary to restrict carbohydrates to less than 20 grams per day to enter ketosis, which causes ketones (substances that are left when the body burns fat) to accumulate in the body.

Ketosis can be beneficial in some cases, but it can also have side effects, such as nausea, headaches, mental and physical fatigue and bad breath.

Ketosis is the opposite of what happens when you eat foods high in carbohydrates.

Carbohydrates cause an increase in blood glucose levels (glucose is the product of digestion and assimilation of carbohydrates), which causes the pancreas to secrete insulin. Insulin is the hormone that allows cells to take glucose into the blood for energy.

Insulin essentially helps cleanse the blood of extra glucose and keep the body in homeostasis.

When there is more glucose present than the cells need, which is often the case, considering that they do not need an unlimited amount of energy, the excess glucose is converted into glycogen to be stored in the liver and muscle cells. The reserved glucose is waiting for its future use.

When there is still an excess available, the rest is converted into fat and stored around the body. Ketosis essentially breaks this cycle.


Why would someone choose a diet that is very low in carbohydrates / without carbohydrates?

Most people who try these diets seek to achieve one of several goals: lose weight quickly (such as going into “ketosis”), reduce dependence on things like refined wheat or cereals to change their general eating habits and normalize markers as blood sugar levels or cholesterol.

However, not all low carb diets emphasize eating alone or most unprocessed foods, which is an important area where my opinion differs.

The basics of a low carb diet

While a very low carb diet can help you achieve some of the benefits mentioned above, it is very likely to work for more than a few weeks if you really enjoy the types of foods that are very low in carbohydrates (eg meats and oils). ).
Examples of healthy low-carbohydrate foods and foods without carbohydrates include:

Organic and grazed beef, pork, turkey and chicken. Past eggs of chicken, turkey, etc.

Fish and seafood (we recommend fish caught in the wild and avoid seafood, such as shrimp). Good options are salmon, haddock or trout.

Organic or unrefined coconut oil, grape seed, walnut, avocado and olive oil. Butter and lard.

Hard cheese, butter, sour cream and thick cream (we recommend eating grass and organic whenever possible, ideally made with raw milk). Approved cheese products include blue cheese, cheddar cheese, goat, feta cheese, Swiss cheese, parmesan cheese and American cheese.

Herbs and spices, such as curry powder, cinnamon, thyme, cayenne pepper, cumin, paprika, chili powder, 5 spices in powder, dijon mustard, parsley, oregano, basil, tarragon, black pepper, garlic (whole or ground) .

Non-starchy vegetables (low in carbohydrates), such as spinach, cauliflower, Brussels sprouts, green beans, cabbage, cabbage, canned cucumber, tomatoes, jalapeño peppers, broccoli, peppers, lettuce and asparagus.

Other sweeter vegetables have more carbohydrates, but they can still be healthy. These include tomatoes, zucchini or eggplant, squash, peppers, carrots, etc. Water, tea and coffee are virtually free of carbohydrates.

On the other hand, limiting the foods below is important to keep carbohydrate intake very low.

All grains (including wheat, barley, oats, rice and other whole grains). This also includes all foods made with grain flour, such as bread, cakes, cookies, chips, cereals, muffins, pasta, etc.

Sugar and foods that contain artificial or added sweeteners (honey, cane sugar, coconut sugar, etc.)

Most fruits and commercial fruit juices (the juice is high in sugar, with the exception of lime or lemon juice).

Most prepared condiments, sauces or package mixes, which tend to be high in sugar

Most dairy products that contain milk, yogurt, ricotta or cottage cheese. High-fat and low-carb cheeses are allowed because they have very few carbohydrates.

Alcohol, soft drinks and other sugary drinks. For the sake of keeping synthetic ingredients out of your diet, I also recommend avoiding “diet” or light foods that reduce fat and artificial ingredients.

To compensate for the loss of fat, these products are usually made with additional thickeners, emulsifiers or artificial sweeteners.

Although they are not rich in carbohydrates, you would definitely also avoid foods made with trans fats or hydrogenated oils, which include most junk foods or fast foods / fries.

Warnings

Most people can safely start any type of low carb diet immediately. But in the following three situations you may need additional preparation or adaptation:

Are you taking medications for diabetes, p. insulin?
Do you take medications for high blood pressure?
Are you breastfeeding?

If you are not in any of these groups, you are ready to follow a low carb diet.


What to eat on a low carb diet
In this section, you can learn exactly what to eat at low carbohydrates, whether you prefer visual guides, detailed food lists, delicious recipes or a simple guide to get started.

Let’s start with a quick visual guide to low carb. These are the basic food groups that you can eat all you want, until you are satisfied.


Appetizers:
You probably do not need to eat so much in low carbohydrates, as you will feel satisfied longer.

However, if you want something immediately, you could have cheese, nuts, sausages or even an egg. There are many incredible options.


Bread:
There are good and bad carbohydrate choices: you’ll probably want to get away from the store’s “low carb” bread!


How to eat more fat:
The fat is abundant and a surprising flavor enhancer.

Tip: Eat enough good fat to feel satisfied and not be hungry.

Avoid special products:

Low-carbohydrate products such as chocolate, candy, pasta and bread often use all kinds of deceptive marketing, while in reality it is junk food.


Try to avoid:
This is what you should not eat with low carbohydrates: foods full of sugar and starch.
Potential benefits of this diet

Why would you consider eating less carbohydrates? There are many potential benefits, proven by science and experience.

Most people start eating less carbohydrates to lose weight, a well-known and often highly effective method. However, the reason why many people continue to eat low carb is more often the powerful effects on health.

A low carbohydrate diet can help in the reversal of type 2 diabetes. Low-carb diets can normalize blood sugar and, therefore, reverse type 2 diabetes.

A low carb diet can also be very useful in the management of type 1 diabetes. Low carbohydrates can result in a calmer stomach, less (or no) gas, less cramping and pain, etc.

For some people, this is the main benefit, and it usually only takes a day or two to experience it.

Reduce sugar cravings. Low carbohydrates usually reduce and sometimes even eliminate cravings for sweets-

The above benefits are extremely common. Did you know that low levels of carbohydrates can often normalize blood pressure, produce less acne, control migraine and epilepsy, and much more?

Although not all people react positively to ketosis or a diet without carbohydrates, research shows that for those who are good candidates, you can experience the following health benefits.

Rapid weight loss Satiety improved by eating or hunger and reduced cravings (especially for sweets).

Better control over insulin spikes and blood sugar (glucose). This can be especially beneficial for prediabetics or diabetics, although low-carbohydrate diets are not the only way to reduce diabetes risk factors.

Neuroprotective effects and better cognitive performance, including less brain fog or falls in energy, better memory in the elderly and reduction of the symptoms of epilepsy.

Sometimes, better sleep, less muscle pain or weakness, and more energy in general. Reduction of bone loss or osteoporosis.

In athletes, possible favorable changes in body mass and body composition, together with an increase in the relative values ​​of maximum oxygen uptake and oxygen consumption at the lactate threshold.

In some cases, lower risk of cardiovascular disease or metabolic syndrome, including normalization factors such as high blood sugar or unhealthy cholesterol levels.

Sometimes even substantial reductions in body fat are very common when consuming a very low carbohydrate diet. The reason why this happens is due to the effects of lowering glucose, as described above.

Once the glucose in carbohydrate foods is no longer available for energy, the body will use stored body fat instead, or fat and protein consumed from food.

Eliminating foods such as fruits, starchy vegetables, pasta and bread from your diet will also cause the body to release less insulin, which helps balance blood sugar levels and reduce the risk of diabetes.

While this is very useful, it is not the only way to lose weight or improve things like blood sugar and cholesterol. Research shows that almost any diet that helps you achieve a healthier body weight can reduce or even reverse the risk factors of cardiovascular disease / metabolic syndrome.

Here are more details about the potential benefits of a carbohydrate-free diet:

Promotes weight loss:

If you follow a diet without carbohydrates, you will inevitably lose weight. Although research is limited in carbohydrate-free diets specifically, there have been a number of studies demonstrating the benefits of low-carbohydrate or ketogenic diets in weight loss.

Following a very low carbohydrate diet with less than 50 grams of carbohydrates per day had a more significant impact on long-term weight loss compared to following a low-fat diet.

In addition, fats and proteins tend to be fuller, which can help reduce hunger and promote satiety.

However, perhaps even more likely to contribute to weight loss in a carbohydrate-free diet plan is the lack of carbohydrate-free foods available. In this diet plan, you only eat meat and fat along with the occasional tea or coffee you pour.

Unless you’re eating coconut oil and butter next to the cup, losing weight is practically inevitable.


It can improve brain health:
Ketogenic diets have been used to treat a variety of conditions throughout history. In fact, they have been used to treat epilepsy since at least 500 a. C. and maybe even before.

Especially in children, the ketogenic diet has been shown to be effective in controlling seizures with some regimens that limit carbohydrate intake to only a few grams per day.

In addition, some research has found that the ketogenic diet could be a promising treatment for Alzheimer’s disease and Parkinson’s disease.

Keep in mind, however, that most current research examines ketogenic diets that severely restrict carbohydrates but do not eliminate them completely. More studies are needed to evaluate the effects of a carbohydrate-free diet plan.

It could help protect against cancer:

Some studies suggest that the ketogenic diet may be beneficial in the treatment of cancer essentially by “dying of starvation” of cancer cells from glucose or sugar.

They point out that these cells depend on sugar to survive and can not change and start using fat as energy instead.

A 2014 review hypothesized that a ketogenic diet could cause oxidative stress in cancer cells, which can potentiate the effects of chemotherapy and radiation by increasing their sensitivity to these cancer treatments.

In an animal study, mice with prostate cancer that were fed a high-fat, non-carbohydrate diet had significantly lower tumor growth than mice fed a traditional western diet.

Of course, more research is needed to understand how a diet without carbohydrates can affect the long-term development of cancer in humans, but these studies show that carbohydrate restriction could be a promising potential approach to cancer treatment.

Hazards of the diet without carbohydrates (Diets very low in carbohydrates)

Some research has found that diets without carbohydrates (or similar diets very low in carbohydrates such as the ketogenic diet) can cause side effects, complications or worsen symptoms in some people.

Depending on factors such as your medical history, age, sex, activity level, body weight and genetic disposition, you can find a diet without carbohydrates that is very beneficial or very difficult to follow, and also the cause of certain negative reactions.

Taking into account the potential dangers of diets without carbohydrates, it is generally very important to pay attention to how you feel when changing your diet, including seeking changes in your energy, sleep, moods, strength and digestion.

This is how you will finally reach the level of carbohydrates in your diet that works best for you personally.

Below are eight possible dangers or symptoms that can be caused by greatly reducing carbohydrates in your diet:

Fatigue or lethargy.
Problems to exercise due to weakness or loss of interest in being active because you feel tired.
Problems to sleep.
Digestive problems, such as constipation or diarrhea (usually due to low fiber intake).
Acid reflux, gas, indigestion due to eating too much fat and protein, especially when not enough water is taken, enough salt is obtained or fiber is consumed.
Irritability or mood swings (which can occur when reducing carbohydrate intake, which affects serotonin levels).
Bad breath.

When carbohydrates remain very low for prolonged periods, deficiencies of vitamins or minerals, bone loss and gastrointestinal disorders are also possible.

Why do these side effects occur at some point?

Ketosis has been shown to have adverse effects in some children, and not even all adults respond to eating the same amount of carbohydrates in the same way.

Because we all have different genetics, metabolisms and capacities to store greater amounts of body fat or muscle, it is important to adapt your diet to your lifestyle, goals and needs.

It is recommended that if you try a diet without carbohydrates, do it in phases to help your body adapt to the decreasing levels of glucose.

Once you have eaten this way for a short period of time, you can reintroduce healthy foods in your diet that contain carbohydrates, paying special attention to what foods (and in what amounts) help you maintain your healthy weight, versus those that they move him away. of your goal

To monitor yourself for adverse reactions, when you reduce carbohydrate intake to very low levels, first consider breaking the carbohydrate dependency cycle by eliminating sources such as sugar.

Slowly continue to decrease carbohydrates until almost all the carbohydrates in your diet are gone to change your metabolism to depend on carbohydrates / glucose for energy and store body fat.

Then you can do the reverse after several weeks: increase your carbohydrate intake by about five to 10 grams per day for one or two weeks, which will give you time to calculate how many carbohydrates you can tolerate while losing weight or at least it does not recover.

You can establish between 25-150 grams of net carbohydrates a day or even more if you are active. Again, this will depend on your individual metabolism and activity level.

While a diet without carbohydrates may have some health benefits, keep in mind that you can get the same benefits through a low carb or ketogenic diet.

Not only are these diets easier to follow, they are also much less restrictive and are associated with fewer risks and side effects.

Because carbohydrate-free diet plans eliminate virtually all sources of carbohydrates, including healthy carbohydrates, there is a much higher risk of nutritional deficiencies.

Whole grains, for example, provide B vitamins, magnesium and vitamin E, while fruits and vegetables contain a wide range of vitamins and minerals that are not found in meats or fats.

It is also important to make sure you meet your caloric needs in this plan. Severe calorie deprivation can cause symptoms such as fatigue, low blood sugar and loss of muscle mass.

Excessively high protein intake could also worsen kidney function in those with kidney disease. Because a diet without carbohydrates is very high in protein, it is not recommended for people with kidney failure.

In addition, this diet is difficult to maintain and should not be followed for long periods of time due to the risk of long-term side effects.

People with certain health conditions such as diabetes should consult their doctors before following a diet low in carbohydrates or without carbohydrates, as it can affect the doses of medications such as insulin.

Precautions regarding very low carbohydrate diets

Check with your doctor or health care provider before starting any low carb diet, especially if you have a health problem that requires monitoring and medications, such as diabetes or heart disease.

As with all dietary plans, it is important to practice self-awareness if you plan to drastically reduce carbohydrate intake or eliminate glucose / carbohydrate sources all together.

Controlling your reactions closely and talking to your doctor in advance are especially important if you have a history of underweight or fatigue.

Very low carbohydrate diets are more likely to cause negative reactions for people who tend to be very thin to start, are very active, the elderly, those who have a health problem related to hormones or anyone with an autoimmune disorder .

Nor should you try a diet without carbohydrates if you are pregnant or breast-feeding.

Side effects of the carbohydrate-free, low-carbohydrate diet may include low energy, increased cravings, irritability, constipation, digestive problems and weakness.

It is not recommended to follow a carbohydrate-free diet for a prolonged period unless under medical supervision, as it is likely to lead to nutrient deficiencies.

If you have diabetes, you should talk to your doctor before adjusting your carbohydrate intake. Changes in carbohydrate intake may alter the effects of medications such as insulin and it may be necessary to recalculate the dose.

A diet without carbohydrates is also not recommended for those with kidney disease, since excessive intake of protein can cause damage to the kidneys.

If you are interested in reaping the benefits of a low carbohydrate or ketogenic diet on weight loss and health, it is best to try these less restrictive diets, as they are safer and easier to follow.

As always, listen to your body and, if you experience negative side effects, talk to your doctor immediately and consider increasing your carbohydrate intake.

Should I follow a diet without carbohydrates or not? Who is good for?

Following a diet plan without carbohydrates for two weeks can seem like a daunting task, and even eating only meat and fat for a day or two seems challenging.

Instead of following a carbohydrate-free diet, start by reducing the intake of unhealthy carbohydrates, such as refined grains, junk food and ultra-processed foods.

Other foods and drinks that make the list of bad carbohydrates include soda, fruit juice and anything with added sugar.

If you are interested in a low-carb diet plan to lose weight, try gradually decreasing carbohydrate intake by switching to more healthy fats and proteins instead of carbohydrates.

For the carbohydrates you eat, make sure they are rich in fiber and important nutrients. Fruits, vegetables and whole grains are good options to add to your plate.

You can also try a ketogenic diet, which cuts even more carbohydrates, forcing your body to burn fat to get fuel instead of sugar.

However, following a carbohydrate-free diet is not advisable unless you are medically prescribed for a condition, such as epilepsy.

Not only is it difficult and unsustainable, but a diet without carbohydrates is very likely to generate gaps in important nutrients that could cause negative health effects.
