The ketogenic (keto) diet is a high-fat, low-carbohydrate diet that puts the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. The standard recommendation for the maximum number of carbs one can eat while staying in ketosis is 20-50 grams per day, but this may vary depending on individual factors such as activity level, stress, sleep, and metabolism. Some people may be able to consume more than 50 grams of carbs without getting kicked out of ketosis, especially if they engage in intense workouts. To stay within the recommended carb range on the keto diet, individuals must cut out or significantly reduce their intake of carb-rich foods such as bread, pasta, potatoes, fruits, and some vegetables.

The standard keto diet recommends 20-50 grams of carbs per day
The keto diet is a high-fat, low-carb diet that puts the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. This diet is restrictive and challenging to maintain, and it is not recommended for athletes due to its negative impact on performance.
To achieve ketosis, it is essential to monitor your carbohydrate intake and choose foods with minimal carbs per serving. The keto diet involves avoiding carb-rich foods like bread, pasta, and potatoes and significantly reducing fruit and vegetable intake. Instead, the diet focuses on high-fat foods such as meats, fish, nuts, seeds, butter, cream, and oils.
Counting net carbs, which considers the fibre and sugar alcohol content of foods, is a common practice on the keto diet. Net carbs can be calculated by subtracting the amount of fibre and half the sugar alcohol content from the total number of carbs in a serving. This calculation helps individuals stay within the recommended carb range and ensure they are getting enough fibre and nutrients.

The targeted keto diet allows more carbs around high-intensity workouts
The keto diet is a high-fat, low-carb diet that puts the body into a state of ketosis, where the body burns fat instead of carbohydrates for energy. The standard ketogenic diet recommends that 70% of a person's intake be fat, 20% be protein, and 10% be carbs. However, the targeted ketogenic diet (TKD) allows for more carb consumption specifically around high-intensity workouts.
The TKD is a variation of the standard keto diet that focuses on the timing of carbohydrate intake to enhance exercise performance. On the TKD, dieters consume their daily allotment of carbs before, during, or after a workout. This approach may be particularly beneficial for athletes or individuals engaging in high-intensity exercises who are looking to boost their performance. The extra carbs provide glucose, which can improve strength and endurance during high-intensity activities.
The TKD is positioned between the standard ketogenic diet and the cyclical ketogenic diet (CKD) on the spectrum of keto diets. The standard keto diet is generally recommended for individuals engaging in light to moderate-intensity exercises, while the cyclical keto diet is designed for serious athletes and involves eating a large number of carbs one or two days per week and eating very low-carb for the rest of the week. The targeted keto diet offers a compromise between these two approaches, allowing individuals to maintain high-intensity exercise performance while still reaping the benefits of ketosis.
It is important to note that the effectiveness of the TKD may vary depending on individual factors. Some people may find that they can consume more carbs and still achieve ketosis, while others may need to be more strict. Additionally, the TKD may be most beneficial for those who are new to the keto diet, as the extra carbs may not provide the same performance boost once an individual becomes keto-adapted.
Overall, the targeted ketogenic diet allows for more carb consumption specifically around high-intensity workouts, providing a potential solution for athletes or individuals looking to enhance their performance without sacrificing the benefits of ketosis.

Keto diet composition: 60% fat, 35% protein, 5% carbs
The keto diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. The standard ketogenic diet (SKD) is the most researched and most recommended. It involves limiting your body's supply of glucose (sugar) by reducing your consumption of carbohydrates, forcing your body to burn fat for fuel instead of carbs, a metabolic state known as ketosis.
The keto diet composition of 60% fat, 35% protein, and 5% carbs is known as the targeted ketogenic diet (TKD) or the high protein ketogenic diet. This diet allows you to add carbs around workouts and includes more protein than the SKD. The ratio of 60:35:5 is often rounded to 60:30:10, which is also considered acceptable for the keto diet.
The targeted ketogenic diet is more flexible than the standard ketogenic diet and is primarily used by bodybuilders or athletes. It is considered an advanced method and is less extensively studied than the SKD.
To achieve ketosis, it is recommended to limit carb consumption to 20-50 grams per day. However, the number of carbs you can eat while staying in ketosis depends on individual factors such as metabolic flexibility, body size, and level of physical activity.
The keto diet is restrictive and challenging to follow for long periods. It is important to monitor your health and nutrient intake while on the keto diet, as restricting your carbohydrate intake may lead to nutrient deficiencies.

Keto diet side effects include keto breath and constipation
The keto diet is a high-fat, moderate-protein, and low-carb diet designed to help achieve ketosis, a metabolic state where the body burns fat instead of carbohydrates for energy. The standard ketogenic diet comprises 70% fat, 20% protein, and 10% carbs. However, the acceptable number of carbs can vary between 20 to 50 grams per day to maintain ketosis. Exceeding this limit may cause side effects such as keto breath and constipation.
Keto Breath
Keto breath is a distinctive side effect of the keto diet, resulting from the body entering ketosis. It typically manifests as a fruity or metallic taste in the mouth, accompanied by a strong odor resembling nail polish remover. This occurs due to the presence of ketones, specifically acetone, in the breath. While keto breath is temporary, lasting a couple of weeks, it can be mitigated by:
- Increasing water intake to flush out ketones through urination.
- Lowering protein consumption as the breakdown of protein produces ammonia, another contributor to breath odor.
- Maintaining good oral hygiene, including brushing teeth twice daily, flossing, and using mouthwash.
- Consuming sugar-free gum or mints to mask the odor.
Constipation
Constipation is a common side effect of the keto diet due to the reduction in fiber-rich foods like fruits, whole grains, and starchy vegetables. Fiber is essential for maintaining regular bowel movements, and insufficient fiber intake can lead to constipation, characterized by fewer than three bowel movements per week, hard and lumpy stools, and difficulty passing them. To prevent or alleviate constipation on the keto diet:
- Gradually transition to the keto diet, starting with a higher daily carb intake of around 50 grams and slowly reducing it as the digestive system adjusts.
- Ensure that fats and proteins are derived from whole foods rather than processed meals, as they can stress the gastrointestinal system.
- Increase water intake and incorporate more fiber-rich keto-friendly foods like leafy greens, broccoli, nuts, seeds, and berries.
- Engage in brisk walks after meals to stimulate digestion and promote bowel movements.
While keto breath and constipation are common side effects of the keto diet, they can be managed through adjustments to diet, hydration, and physical activity. It is important to monitor these side effects and consult a doctor if they persist or lead to further complications.

Keto-friendly foods: vegetables, fruits, fatty fish, and avocados
The keto diet is a high-fat, very low-carbohydrate, and moderate-protein diet. The body enters a state of ketosis when carb intake is restricted to 50 grams or fewer per day, causing it to burn fat instead of carbs for energy.
Vegetables
Non-starchy vegetables like broccoli, cauliflower, zucchini, bell peppers, cabbage, cucumber, eggplant, green beans, and leafy greens are all keto-friendly options. These vegetables are low in carbohydrates, but still provide essential fibre, vitamins, minerals, and antioxidants. Cauliflower, for example, has just 3.2g net carbs per 1 cup serving and can be used as a rice or potato substitute. Zucchini is another versatile option with only 2.4g net carbs per 1 cup serving and can be used to make noodles or casseroles.
Fruits
Olives, avocados, tomatoes, peaches, cantaloupe, watermelon, and berries are some fruits that are suitable for a keto diet. These fruits are lower in carbs compared to other popular fruits. For example, a 100-gram serving of olives contains 6 grams of carbs, while a cup of diced cantaloupe has only 12.7 grams of carbs. However, portion control is still important with these fruits to stay within the carb limits of a keto diet.
Fatty Fish
Fatty fish like tuna, salmon, anchovies, and mackerel are excellent sources of high-quality protein, vitamins (especially vitamin D), and healthy fatty acids (omega-3). They are perfect for creating quick and delicious keto dishes. The higher fat content in these fish may make them even more suitable for a keto diet, as it aligns with the diet's focus on high-fat foods.
Avocados
Avocados are a popular choice among those following a keto diet. They are higher in fat than carbs, with a whole avocado containing 17 grams of carbs and 30 grams of fat. Avocados also provide various vitamins and minerals, including potassium and B vitamins. Additionally, regular consumption of avocados has been linked to improved heart health and reduced levels of "bad" cholesterol.
