No-carb diets, also known as zero-carb diets, are a highly restrictive form of dieting that eliminates all carbohydrates. Carbohydrates are one of the three main macronutrients and are found in a wide range of foods, including fruits, vegetables, legumes, grains, dairy, eggs, and meats. As a result, those on a no-carb diet must consume foods that primarily contain protein or fat, such as meats, fish, eggs, cheese, oils, and butter. While a no-carb diet may lead to short-term weight loss, it can also cause constipation, low energy, and insufficient nutrients.

No-carb diets are likely to result in short-term weight loss, but this is mostly fluid loss
No-carb diets are a highly restrictive form of low-carb diets that have gained popularity due to the supposed link between carbohydrates and weight gain. Carbohydrates are one of the three main macronutrients in food, along with fat and protein, and they perform essential bodily functions like digestion, absorption, and metabolism. They are also the body's primary source of energy.
No-carb diets, as the name suggests, aim to eliminate all carbohydrates from the diet. Foods typically allowed on a no-carb diet include meat, fish, eggs, cheese, butter, oils, nuts, seeds, and non-starchy vegetables. While this diet can lead to short-term weight loss, it is mostly due to fluid loss or water weight. Carbohydrates are stored along with fluid, and each gram of carb holds approximately three grams of water. Thus, in the initial weeks of a no-carb diet, the rapid weight loss is due to the loss of water weight.
The recommended daily intake of carbohydrates is between 45% and 65% of a person's calorie intake. Low-carb diets, including the ketogenic diet, typically limit carb intake to fewer than 20-50 grams per day. While these diets can lead to dramatic weight loss, they are not without risks and should be approached with caution. The body needs some carbs to function properly, and eliminating them entirely can be challenging and may negatively impact health.
Additionally, no-carb diets can be very low in fiber, which is essential for digestion and maintaining bowel regularity. The restriction of fruits, most vegetables, beans, and whole grains in a no-carb diet can lead to insufficient nutrient intake, including vitamins and minerals like potassium, B vitamins, and vitamin C. Furthermore, the increased urination associated with restricting carbs can lead to nutrient deficiencies over time.
While no-carb diets may result in short-term weight loss, it is important to consider the potential risks and negative impacts on health. It is always advisable to consult with a healthcare professional before starting any restrictive diet, especially one as extreme as a no-carb diet.

Carbs are your body's primary source of energy, so a no-carb diet may lead to low energy and fatigue
Carbohydrates are one of the three main macronutrients, along with protein and fat. They are the body's preferred source of fuel for energy, muscles, and the brain. Connie Diekman, former president of the Academy of Nutrition and Dietetics, explains that:
> Muscles can store a little carb and use ketone bodies from fat for fuel but the brain needs carbs and won’t work as well without them.
Therefore, a no-carb diet may lead to low energy and fatigue. This is because the body is not receiving its primary source of fuel. In addition to low energy, other side effects of a no-carb diet may include constipation, insufficient nutrients, headaches, and irritability.
No-carb diets are highly restrictive and eliminate all carbohydrates. They are often pursued for weight loss, as reducing your carb intake can help you lose weight. However, it is important to note that research is still mixed on whether reducing carb intake is better for weight loss and health. Some studies have suggested this to be the case in the first six months but not as much in the long term.
Foods that are typically allowed on a no-carb diet include meat, fish, eggs, cheese, butter, oils, water, and plain coffee or tea. Some people who follow a no-carb diet also eat nuts, seeds, non-starchy vegetables, and high-fat fruits like avocado and coconut, as these foods are low in net carbs.

A no-carb diet may not provide enough vitamins and minerals, such as potassium, B vitamins, and vitamin C
No-carb diets are an extreme version of low-carb diets and cut out carbohydrates completely. There is no strict rubric for a no-carb diet, but it generally involves eliminating all carbohydrates. This means cutting out foods such as milk, yogurt, fruits, vegetables, legumes, beans, pasta, bread, baked goods, sugars, sweetened beverages, and grains.
Nuts, seeds, avocado, and coconut are also included in some no-carb diets and are good sources of vitamins and minerals. However, because a no-carb diet restricts fruits, most vegetables, beans, and whole grains, it can be very low in fiber, which is important for digestion and maintaining bowel regularity.
In addition, the increased urination that results from restricting carbohydrates may lead to nutrient deficiencies such as sodium and potassium over time. Therefore, it is important to consult with a doctor or registered dietitian before starting a no-carb diet to ensure that you are getting all the necessary nutrients and that the diet is safe for you.

A no-carb diet is not well researched for safety and is not recommended for those with eating disorders, children, or pregnant people
A no-carb diet involves eliminating digestible carbohydrates and replacing them with foods that contain primarily protein or fat. This includes meat, fish, eggs, cheese, oils, and butter. Some people also eat nuts, seeds, non-starchy vegetables, and high-fat fruits like avocado and coconut.
While a no-carb diet may help with weight loss and promote feelings of fullness, it is highly restrictive and not well-researched for safety. As such, it is not recommended for certain populations, including those with eating disorders, children, and pregnant or nursing people.
For individuals with eating disorders, highly restrictive diets like no-carb can be triggering and detrimental to their health. It is important to seek professional guidance and prioritize a balanced approach to nutrition.
In the case of children, their growing bodies have unique nutritional needs. While some sources suggest that low-carb diets can be safe and effective for weight loss in adolescents, others emphasize the importance of whole foods and adequate nutrients to support growth. Restrictive diets may deprive children of essential vitamins and minerals, impacting their overall health and development.
Pregnancy and breastfeeding are also periods when nutritional needs are heightened. The limited research on no-carb diets during pregnancy suggests controversy and a lack of evidence-based medicine. While some women continue a ketogenic diet during pregnancy, concerns arise around conditions like diabetic ketoacidosis or starvation ketosis. It is crucial for pregnant and nursing individuals to prioritize a well-rounded diet to support both their health and the development of their child.
Overall, while a no-carb diet may offer certain benefits, it is important to approach it with caution and consider individual circumstances. Those considering a no-carb diet should consult with their healthcare provider to ensure it is safe and appropriate for their specific needs.

Meat, fish, eggs, cheese, butter, oils, water, and plain coffee or tea are allowed on a no-carb diet
A no-carb diet is an extreme version of a low-carb diet, eliminating almost all carbs, including whole grains, fruits, and vegetables. While studies show that decreasing your carb intake can help you lose weight and may have health benefits, completely eliminating carbs is highly restrictive and most likely unnecessary.
Eggs are a good source of protein and are allowed on a no-carb diet. Research has shown that eating eggs for breakfast can help with weight loss.
Cheese is allowed on a no-carb diet, with full-fat cheese being preferable to low-fat cheese. Cheddar, Gouda, blue cheese, and goat cheese are good choices due to their suitable high-fat and low-carb content.
Butter is allowed on a no-carb diet. It is a good source of antioxidants that fight inflammation and may help prevent strokes.
Oils such as olive oil, coconut oil, and canola oil are allowed on a no-carb diet. Coconut oil may boost heart health and encourage fat burning.
Water is completely free of carbs and is allowed on a no-carb diet. Plain coffee and tea are also allowed, as they are full of antioxidants and can help increase focus and mental clarity. However, milk, sugar, and other sweeteners are not allowed in coffee or tea on a no-carb diet.
