The keto diet is a high-fat, low-carb, moderate-protein diet. The typical macro ratio for keto is 70% fats, 5% carbohydrates, and 25% protein. However, there are differing opinions on the right way to do keto, with some dietitians recommending a macro split of 75% fats, 5% carbohydrates, and 20% protein.
The keto diet focuses on limiting carbohydrate intake so that the body enters a state of ketosis, where it burns fat for energy instead of glucose. To achieve this, it is recommended to consume less than 50 grams of carbohydrates per day, with some sources suggesting a range of 20 to 50 grams.
The specific macro ratio will depend on individual factors such as sex, height, weight, age, and activity level. For example, a moderately active 30-year-old woman aiming to lose weight may have keto macros of 24 grams of carbohydrates (5%), 145 grams of fat (69%), and 126 grams of protein (27%).
It is important to note that the keto diet may have side effects, such as keto flu, and it may be challenging to follow long-term due to its restrictiveness. Consulting a healthcare professional before starting any new diet is always recommended.

What You'll Learn
- The keto diet is high in fat, low in carbs, and moderate in protein
- Carbohydrates should make up 5% of your daily calorie intake
- Fat should make up 70% of your daily calorie intake
- Protein should make up 20-30% of your daily calorie intake
- The keto diet may be unsafe for people with type 1 diabetes and pregnant people
The keto diet is high in fat, low in carbs, and moderate in protein
The keto diet is a high-fat, low-carb, and moderate-protein diet. It involves drastically reducing your carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where it becomes very efficient at burning fat for energy.
The typical keto macro ratio is 70% fats, 5% carbohydrates, and 25% protein. However, some dietitians recommend increasing fat intake to 75% and reducing protein to 20%. The keto diet is highly restrictive, and it can be challenging to follow for long periods.
- Have a plan: Set aside time for meal planning and preparation to ensure your meals align with the recommended macros.
- Be patient: It takes around three to five weeks to transition into ketosis, and you may experience some side effects during this time.
- Track your food: Use an app to monitor your food and macronutrient intake, especially during the first two weeks of the diet.
- Choose the right foods: Prioritize nutrient-dense leafy greens, high-quality proteins, and healthy fats from plants, nuts, and seeds.
- Stay hydrated: Drinking plenty of water is essential when consuming a high-fat diet.
Remember to consult a healthcare professional before starting any new diet, especially if you have existing health conditions or are taking medications.

Carbohydrates should make up 5% of your daily calorie intake
The keto diet is a low-carb, high-fat, and moderate-protein diet. The idea is that by reducing your carbohydrate intake, your body will enter a state of ketosis, where it burns fat for energy instead of glucose.
The keto diet typically follows a macro ratio of 70% fats, 5% carbohydrates, and 25% protein. However, some dietitians recommend increasing the proportion of fats to 75% and lowering protein to 20%.
On a 2,000-calorie diet, this would mean consuming less than 50 grams of carbohydrates per day. To achieve this, you should avoid bread, pasta, grains, rice, sugary snacks, beans, and most fruits. Instead, focus on fatty fish, dairy products, nuts, seeds, oils, meat, and non-starchy vegetables.
It's important to note that the keto diet can be restrictive and challenging to follow long-term. It may also lead to nutrient deficiencies, so it's crucial to find keto-friendly sources of essential nutrients. Additionally, it's recommended to consult a healthcare professional before starting any new diet.

Fat should make up 70% of your daily calorie intake
The keto diet is a high-fat, low-carb, and moderate-protein diet. It involves getting about 70% of your daily calorie intake from fat, 5% from carbohydrates, and 20-30% from protein.
On a 2,000-calorie diet, this would mean consuming around 144-177 grams of fat each day. This is a significant amount and can be challenging to achieve, especially for those used to a high-carb diet. However, it is crucial for keeping the body in a state of ketosis, where it burns fat for fuel instead of carbohydrates.
- Enjoy fatty fish like salmon, tuna, mackerel, sardines, and anchovies.
- Avocados and avocado products are a great source of monounsaturated fats.
- Use plant-based oils like olive oil, avocado oil, and walnut oil for cooking.
- Nuts and seeds, as well as nut and seed butters, are a good way to add healthy fats to your diet.
- Include beef, pork, and lamb in your meals.
- Try fat bombs, which are bite-sized snacks made with high-fat ingredients like cream cheese, nut butters, and coconut oil.
- Make bulletproof coffee by blending brewed coffee with grass-fed butter and MCT oil.
- Enjoy creamy soups and sauces made with full-fat dairy.
- Use multiple fat sources at each meal. For example, add a fried egg and some cheese to your avocado toast.
- Dunk low-carb veggies like celery and cucumber in high-fat dips like creamy onion dip or blue cheese dressing.
- Roast vegetables in healthy oils like olive oil and avocado oil.
- Sprinkle nuts and seeds on your meals or use them to make a crunchy crust on pies.
- Make smoothies with full-fat dairy like heavy cream, full-fat yogurt, and whole milk.
- Add shredded coconut to your snacks and sweets for an extra boost of healthy fats.

Protein should make up 20-30% of your daily calorie intake
Protein is one of the three macronutrients, along with carbohydrates and fat. It plays a vital role in the body, from building and repairing muscles to supporting healthy skin, hair, and nails. When following a keto diet, it is important to ensure you are consuming adequate amounts of protein to support these essential functions.
Generally, it is recommended that individuals on a keto diet aim for 20-30% of their calories to come from protein sources. This equates to approximately 100-150 grams of protein per day for someone consuming 2,000 calories. However, the specific amount of protein needed can vary depending on factors such as age, activity level, and weight goals.
To calculate your personalised protein range, it is recommended to use your body weight in kilograms as a starting point. For example, if you weigh 60 kilograms, your protein range would be 72-120 grams per day (1.2-2.0 g/kg body weight). It is important to note that this range may need to be adjusted based on your individual needs and lifestyle factors.
Consuming enough protein on a keto diet is crucial not only for maintaining muscle mass but also for supporting overall health and well-being. By including a variety of protein-rich foods in your diet, such as meat, poultry, seafood, eggs, dairy, nuts, and seeds, you can ensure you are meeting your protein requirements while still adhering to the keto guidelines.
In addition to the amount of protein consumed, it is also important to consider the quality of protein sources. Prioritising healthy, whole food options and ensuring adequate overall calorie intake will support your body's ability to utilise protein effectively. Remember, while protein is essential, it is just one component of a balanced keto diet, which also includes healthy fats and low-carbohydrate options.
One common concern among those following a keto diet is the fear of consuming too much protein and potentially being kicked out of ketosis. While this is theoretically possible, it is unlikely to occur if you are following the recommended protein guidelines. Gluconeogenesis, the process by which the body converts amino acids from protein into glucose, does occur naturally and is necessary for maintaining adequate glucose levels. However, studies suggest that extra protein intake does not lead to a significant increase in gluconeogenesis.
It is worth noting that individual needs may vary, and some people may require higher or lower protein intakes depending on their health status, activity level, and weight management goals. For example, those aiming to lose weight while maintaining muscle mass may benefit from a higher protein intake, while those with type 2 diabetes may need to monitor their protein consumption more closely to manage blood sugar levels effectively.
While it may be tempting to restrict protein intake in favour of higher fat consumption on a keto diet, it is important to remember that inadequate protein intake can lead to several health issues. Over time, low protein intake can result in muscle mass loss, appetite changes, weight gain, delayed wound healing, fatigue, and an increased risk of certain health conditions. Therefore, it is crucial to prioritise protein intake and include a variety of protein-rich foods in your keto diet to support overall health and well-being.

The keto diet may be unsafe for people with type 1 diabetes and pregnant people
The keto diet is a very-low-carb, high-fat diet. Typically, the keto diet involves getting 70-80% of calories from fat, 5% or fewer from carbohydrates, and 20-30% from protein.
The keto diet may be unsafe for people with type 1 diabetes.
The keto diet has been shown to improve blood sugar control and reduce insulin requirements in people with type 1 diabetes. However, several complications can arise for this group.
The keto diet can lower blood sugar too much, which can lead to confusion, dizziness, slurred speech, and loss of consciousness. It's important to adjust insulin dosing to prevent this.
The keto diet can also cause unwanted weight loss, which may be undesirable or unsafe for some people, especially those who are underweight.
Additionally, some people with type 1 diabetes should avoid the keto diet, including those with a history of chronic low blood sugar, people who are underweight or have an eating disorder, and pregnant or breastfeeding mothers.
The keto diet may be unsafe for pregnant people.
There is limited research on the effects of the keto diet during pregnancy. Some studies on mice have shown that a ketogenic diet caused changes to embryo development, suggesting potential birth defects. However, another study found that the offspring of mice on a ketogenic diet had increased sociability and reduced depression-like symptoms.
There is limited evidence on the safety of ketogenic diets in humans. One case report found that one infant born to a mother on the keto diet had ear abnormalities, while another had no complications.
Ketoacidosis is a serious medical condition characterized by high blood glucose and ketone levels that can be life-threatening for both mother and infant. It is rare for the keto diet to induce high ketone levels, but it is possible.
Overall, it is recommended that pregnant women adopt a more flexible low-carb approach, with a carbohydrate goal of 75-150 grams per day, unless otherwise instructed by a healthcare provider.
In summary, while the keto diet may offer benefits for some people, it may be unsafe for those with type 1 diabetes and pregnant people due to potential complications and limited research on its effects during pregnancy. It is crucial to consult a healthcare professional before starting any new diet, especially for those with type 1 diabetes or pregnant women considering the keto diet.
