No-carb or low-carb diets have become increasingly popular due to their association with quick weight loss, lower blood pressure, and better management of health conditions like type 2 diabetes and heart disease. A no-carb diet eliminates carbohydrates, such as grains, fruits, starchy vegetables, legumes, dairy, and sugar, from one's diet. While it may be tempting to try a no-carb diet, it is essential to proceed with caution as carbohydrates are the body's primary energy source, and their reduction can lead to fatigue and flu-like symptoms (keto flu). Furthermore, maintaining a completely no-carb diet can be challenging and may not be sustainable for the long term. Thus, it is recommended to consult a health expert or dietitian before starting and to ensure you are still consuming enough calories and nutrients from other food groups.

What You'll Learn
Seek medical advice first
Before starting a no-carb diet, it is important to seek medical advice. A no-carb diet is an extreme version of low-carb dieting, and while it may provide certain benefits, it can also have side effects and be difficult to sustain.
A no-carb diet eliminates almost all carbohydrates, including whole grains, fruits, and vegetables. Carbohydrates are your body's primary source of energy, and cutting them out can lead to side effects such as weakness, fatigue, dizziness, and headaches. More serious side effects may also occur, such as stomach pain, nausea, and vomiting. Some people may also experience constipation due to the low fiber content of a no-carb diet.
Additionally, a no-carb diet can be restrictive and may not be suitable for everyone. It is important to have close medical supervision, especially if you have an existing medical condition. For example, nutritional ketosis, which is a state your body enters when you drastically reduce carbohydrate intake, can increase uric acid levels, leading to kidney stones or gout flares. Studies have also shown that those who follow a diet high in red meat and low in whole grains, low-fat dairy, and fruit are more likely to develop kidney disease.
Therefore, it is crucial to consult a healthcare professional before starting a no-carb diet. They can assess your individual needs, advise you on potential risks and benefits, and help tailor the diet to your specific requirements. This is especially important if you have any underlying health conditions or take medications that may interact with the diet.
Furthermore, a healthcare professional can provide ongoing support and monitoring to ensure the diet is working safely and effectively for you. They can also advise on supplements or adjustments to mitigate potential side effects and ensure you are getting adequate nutrition while on the no-carb diet.

Plan meals and fitness goals
Planning meals and fitness goals is an important part of starting a no-carb diet. This type of diet is highly restrictive and eliminates almost all carbohydrates, including whole grains, fruits, and vegetables. It is important to consult with a healthcare professional before starting such a restrictive diet to ensure it is safe and appropriate for your individual needs.
Meal planning is essential when following a no-carb diet because it is very restrictive. Meals should be built around meat, fish, eggs, and certain dairy products, such as cheese, butter, and oils. Some people also include nuts, seeds, non-starchy vegetables, and high-fat fruits like avocado and coconut, as these foods are low in net carbs. It is important to note that even these healthy foods contain small amounts of carbohydrates, so portion sizes should be considered.
When dining out, it can be challenging to stick to a no-carb diet. It is helpful to check the menu beforehand to find options that fit within your daily carb allowance. Ask for sauces, condiments, and dressings on the side to control your portion sizes, and consider taking half of your meal to go to reduce carb intake. Opt for meat or fish-based dishes and choose water instead of sugary drinks. Get extra vegetables or a side salad instead of bread, potatoes, or rice.
A no-carb diet may provide benefits such as rapid weight loss, lower blood pressure, and improved blood sugar management. However, it is important to consider your fitness goals and physical activity levels before starting this diet. If you engage in strength or endurance-based exercises, including more carbs in and around your training sessions may be beneficial. It is crucial to listen to your body, and if you experience negative side effects like light-headedness, irritability, bowel issues, or trouble sleeping, you should increase your carbohydrate intake.
Overall, planning meals and fitness goals when starting a no-carb diet involves building meals around animal-based proteins and fats, being mindful of portion sizes, and considering how the diet fits with your physical activity levels and overall health goals.

Avoid grains, fruits, legumes, and starchy vegetables
A no-carb diet is an extreme version of a low-carb diet, eliminating almost all carbohydrates, including grains, fruits, legumes, starchy vegetables, and other food groups. This diet focuses on eating foods that contain primarily protein or fat, such as meats, fish, eggs, cheese, oils, and butter.
Grains are a food group typically high in carbohydrates. Refined grains, such as those found in bread, crackers, pasta, and rice, have been processed and altered to improve their texture and shelf life, resulting in higher net carb content. Therefore, it is best to avoid grains such as wheat, barley, and bulgur, as well as grain-based products like bread, pasta, and rice, when adhering to a no-carb diet.
Fruits naturally contain carbohydrates and should be avoided on a no-carb diet. However, some high-fat fruits, such as avocados and coconuts, are low in net carbs due to their high fibre content and can be consumed in moderation.
Legumes, including beans, peas, and lentils, are also high in carbohydrates and should be avoided. For example, a cup of cooked beans and legumes can contain up to 21 grams of net carbs.
Starchy vegetables, such as corn, peas, and potatoes, contain more digestible carbohydrates than fibre and should be avoided or limited on a no-carb diet. In contrast, non-starchy vegetables are low in calories and carbohydrates and can be consumed freely.

Eat meat, fish, eggs, nuts, seeds, and non-starchy vegetables
A no-carb diet involves eating foods that are high in protein and healthy fats and low in carbohydrates. Meat is a great source of protein and can be eaten in a no-carb diet. This includes chicken, soy products, and other meats. Fish and seafood are also excellent sources of protein and healthy fats and can be included in a no-carb diet. Tuna, salmon, anchovies, and mackerel are rich in high-quality proteins, vitamins (D), and healthy fatty acids (omega-3). They offer many health benefits, including improved heart health, reduced cholesterol, and an enhanced mood.
Eggs are another food group that is perfect for a no-carb diet. Research has shown that eating eggs for breakfast can accelerate weight loss and keep people fuller for longer, reducing the likelihood of overeating later in the day.
Nuts and seeds are a great source of healthy fats and can be included in a no-carb diet. Pecans, for example, are a great option with only 2 net carbs per serving. Brazil nuts are an excellent source of selenium, which is essential for thyroid health, reproduction, DNA synthesis, and protection against various health conditions. Pumpkin seeds, either raw or toasted, are another great addition to a no-carb diet and can be enjoyed as a midday snack or added to salads.
Non-starchy vegetables are an important part of a no-carb diet. These include leafy greens and cruciferous vegetables like broccoli. They are packed with vitamins, minerals, fibre, and phytochemicals, and are low in calories and carbohydrates. It is recommended to consume at least six servings of vegetables per day.

Be aware of the keto flu
The keto flu is a collection of symptoms experienced by some people when they first start a ketogenic diet. It is called the keto flu because your body's response to entering ketosis can often mimic symptoms of the flu. However, despite its name, this is not the flu. You will not develop a fever, and the symptoms can hardly ever make you incapacitated.
Symptoms of the keto flu include:
- Fatigue
- Muscle cramps
- Stomach discomfort
- Stomach aches or pains
- Nausea
- Dizziness
- Sugar cravings
- Cramping
- Muscle soreness
- Irritability
- Diarrhea or constipation
- Trouble falling asleep or staying asleep
- Poor focus and concentration
- Brain fog
- Headaches
These symptoms can range from mild to severe and vary from person to person. For the average person, the keto flu can last a week or less, but in extreme cases, it can last up to a month. However, depending on your genetics, you may never experience the keto flu.
If you are experiencing the keto flu, there are some ways to reduce its symptoms:
- Drink plenty of water. A keto diet can cause you to rapidly shed water stores, increasing the risk of dehydration.
- Replenish electrolytes. The keto diet restricts many foods that are high in potassium, so it's important to replace these lost electrolytes. Salting food to taste and including potassium-rich, keto-friendly foods like leafy greens and avocados are excellent ways to maintain a healthy balance of electrolytes.
- Get plenty of sleep. If you're having trouble sleeping, try taking an Epsom salt bath to soothe and relax your muscles, or drink a keto-friendly herbal tea with herbs that calm your nervous system, like chamomile.
- Light exercise may help relieve muscle pain and tension. Walking, yoga, or leisurely biking may improve symptoms.

Frequently asked questions
A no-carb diet is one that limits foods high in carbohydrates such as grains, fruits, starchy vegetables, legumes, milk, and even non-starchy vegetables like leafy greens, broccoli and bell peppers.
No-carb diets have been linked with quick weight loss, lower blood pressure, and better management of health conditions like type 2 diabetes and heart disease. A 2024 review article in Frontiers in Nutrition found that a low-carbohydrate diet of less than 130g of carbohydrates per day resulted in more favourable effects on average weight loss and risk factors for cardiovascular disease when compared with low-fat diets.
Some people experience "keto flu" when starting a no-carb diet, which involves flu-like symptoms such as fatigue, nausea, and irritability. This is caused by a lack of carbohydrates in the body, which are its primary energy source. Carbohydrates convert to energy more quickly than protein or fat, so a no-carb diet may leave you feeling low on energy. One source also states that a no-carb diet is a quick path to heart disease or diabetes.
