The ketogenic (keto) diet is a high-fat, moderate protein, low-carbohydrate diet. It restricts carbohydrates to 50 grams or less per day, which is far less than the typical intake of 150-250 grams. The keto diet has gained popularity due to its promise of rapid weight loss and has been used to treat epilepsy. However, it is restrictive and challenging to maintain long-term. The Mayo Clinic, a nonprofit academic medical center, has developed a Healthy Keto meal plan that aims to provide a healthier approach to the keto diet by emphasizing healthy fats and including nutrient-rich foods like berries, beans, and vegetables. While the keto diet may offer weight-loss benefits, it is important to consider potential risks, such as keto flu, nutrient deficiencies, and increased risk of certain chronic diseases.

What You'll Learn
The keto diet's health benefits
The ketogenic (keto) diet is a high-fat, moderate-protein, low-carbohydrate diet. The body usually uses carbohydrates as its primary energy source, but the keto diet restricts carbohydrates to 50 grams or fewer per day, forcing the body to use fat as its primary energy source instead. This process is called ketosis, which gives the keto diet its name.
The keto diet has been associated with several health benefits, including:
Weight Loss
The keto diet has been linked to weight loss, which is often the primary motivation for people adopting this diet. By reducing carbohydrate intake, the body shifts to burning fat for energy, resulting in fat loss.
Reduced Hunger
Studies have found that individuals on a keto diet tend to experience reduced hunger and a lower desire to eat. This decreased appetite may be due to the satiating nature of high-fat foods and the body's ability to access fat stores for energy.
Management of Certain Medical Conditions
The keto diet was originally developed by a doctor at the Mayo Clinic over a century ago to treat children with severe epilepsy. Since then, it has been successfully used worldwide to manage drug-resistant epilepsy. Additionally, some people with type 2 diabetes have reported improvements in their condition while on the keto diet, although consulting a healthcare professional before making any dietary changes is essential.
Potential Cardiovascular Benefits
While the keto diet involves consuming more high-fat foods, the New Mayo Clinic Diet's Healthy Keto meal plan provides healthy fats from sources like extra virgin olive oil, avocado, salmon, nuts, and seeds. This approach helps reduce the intake of unhealthy saturated fats, which may have positive effects on cardiovascular health.
It is important to note that the keto diet may not be suitable for everyone and can be challenging to maintain in the long term due to its restrictive nature. Some people may experience negative side effects, such as \"keto flu\" during the transition phase, and an increased risk of constipation, nutrient deficiencies, and heart disease. Consulting with a healthcare professional before starting any new diet, especially if you have existing medical conditions, is always recommended.

Weight loss
The ketogenic (keto) diet is a high-fat, moderate protein, low-carbohydrate diet. Typically, the keto diet restricts carbohydrates to 50 grams per day or less. A more typical intake of carbohydrates is 150-250 grams, or three to five times as much. The reduced carbohydrate intake forces the body to use fat as its primary source of fuel instead of glucose from carbohydrates. This process puts the body in a state of ketosis, meaning the blood has a high level of ketones.
The keto diet has been associated with weight loss. However, it can be challenging to maintain over the long term due to its restrictive nature. Once individuals return to their original eating patterns, they tend to regain the weight they had lost. The keto diet is also associated with an increased risk of constipation, nutrient deficiencies, heart disease, and other chronic diseases. It is not recommended for individuals with certain medical conditions, such as diabetes, heart disease, or thyroid or gall bladder conditions.
The New Mayo Clinic Diet offers a "Healthy Keto" meal plan that has been developed by dietitians. While it still keeps net carbs at around 50 grams per day, it delivers healthy fats from extra virgin olive oil, avocado, salmon, nuts, and seeds. As a result, the meal plan contains less unhealthy saturated fat. It also includes ingredients like berries, beans, and carb-containing vegetables, which provide fiber and other essential nutrients. This healthier approach is easier to stick to long-term and helps maintain overall health.
It is important to note that, as with any diet, it is recommended to speak with a healthcare provider or pharmacist before starting the keto diet, especially if you are considering taking supplements or have existing medical conditions or medications.
Additionally, a well-rounded approach to weight management involves not only dietary changes but also incorporating a calorie deficit and increased physical activity. This holistic approach can help individuals achieve and maintain a healthy weight in a sustainable way.

The diet's restrictive nature
The ketogenic diet is a high-fat, moderate-protein, and low-carbohydrate diet. It typically restricts carbohydrates to 50 grams or fewer per day, which is significantly less than the typical intake of 150-250 grams. This shift in diet forces the body to use fat as its primary source of fuel instead of glucose from carbohydrates. This process is called ketosis, which is where the keto diet gets its name.
The keto diet can be challenging to maintain due to its restrictive nature. It requires a lot of time, planning, and preparation, and many people find it difficult to stick to when dining out. The restrictive nature of the keto diet can also lead to social challenges when eating with others. The diet eliminates many nutrient-rich foods, which can be difficult to cut out and may not be sustainable in the long term.
Some people may find it challenging to eliminate foods such as fruit, cereal, bread, pasta, beans, and potatoes from their diet. These foods are common in many diets and may be challenging to avoid when dining out or socialising with others. The keto diet's restriction of carbohydrates can also be challenging, as carbohydrates are a significant source of energy for the body. While it is possible to reduce carbohydrate intake, it is important to be mindful of the types and amounts of carbohydrates consumed.
The keto diet's restrictive nature can also impact an individual's health. People on this diet have an increased risk of constipation, nutrient deficiencies, heart disease, and other chronic diseases. The diet is not recommended for individuals with certain medical conditions, such as diabetes, heart disease, or thyroid or gall bladder issues. Additionally, individuals may experience "keto flu" symptoms, such as headaches, fatigue, and grogginess, when their body transitions into ketosis.
While the keto diet can lead to weight loss, it may not be the best choice for lifelong weight management due to its restrictive nature. It is important to consider other factors before making drastic changes to dietary patterns. A more sustainable approach to weight management may be to focus on reducing simple carbohydrates and including more complex carbohydrates, which are high in nutrients and fibre, while also incorporating a calorie deficit and increased physical activity.

Risk of nutrient deficiencies
The ketogenic diet, although popular, does come with some risks, including the possibility of nutrient deficiencies. Because the diet is so restrictive, cutting out or severely limiting several food groups, it can be challenging to obtain all the necessary nutrients the body needs. This is especially true if the diet is followed over an extended period.
One of the most common deficiencies associated with the keto diet is thiamine (vitamin B1) deficiency. Thiamine is found in whole grains, legumes, and some fruits and vegetables—all of which are limited on a keto diet. Thiamine deficiency can lead to neurological problems and issues with the heart and cardiovascular system. Another B vitamin that may be lacking is folate (vitamin B9), naturally occurring in green vegetables, beans, and wheat products. Folate is crucial for cell growth and the prevention of anemia; a lack of it can lead to serious health issues, especially during pregnancy, as it is critical for fetal development.
Mineral deficiencies are also a concern. The keto diet may result in a lack of selenium, usually obtained from Brazil nuts, whole grains, and some seafood. Selenium is important for thyroid function and the immune system. Another mineral that may be lacking is magnesium, found in whole grains, nuts, and legumes—all restricted on a keto diet. Magnesium plays a role in over 300 biochemical reactions in the body, including glucose control and blood pressure regulation, and a deficiency can lead to issues with bone health, muscle function, and blood sugar control.
Finally, there is a risk of inadequate fiber intake on a keto diet, as the best sources of fiber include whole grains, legumes, fruits, and starchy vegetables—foods that are limited or avoided. Adequate fiber intake is crucial for digestive health, preventing constipation, and maintaining a diverse population of healthy gut bacteria, which is increasingly recognized as critical to overall health.
To prevent these potential deficiencies, those on a ketogenic diet must be diligent about including a variety of nutrient-dense keto-friendly foods and consider supplementing with specific vitamins and minerals under the guidance of a healthcare professional. It is also worth noting that the longer the diet is followed, the more likely these deficiencies will occur, and the potential consequences can be serious.

The restrictive nature of the keto diet means that many people find it hard to stick to long-term. The diet cuts out fruit, cereal, bread, pasta, beans, and potatoes, which can be difficult to avoid when dining out with others or maintaining the diet over long periods. As a result, people often regain the weight they lost once they return to their original eating patterns.
The New Mayo Clinic Diet's Healthy Keto meal plan has been developed by dietitians to be easier to stick to long-term. While it still keeps carbs low and fats high, it delivers healthy fats from extra virgin olive oil, avocado, salmon, nuts and seeds. As a result, the meal plan contains less unhealthy saturated fat (keeping it below the recommended 10% a day). It also includes good-for-you ingredients like berries, beans, and carb-containing veggies, providing the health benefits of fibre-rich foods like fruits, grains and beans.
The best diet for weight management is one that can be maintained long-term. If the goal is to lose weight, a combination of a healthy eating pattern, a calorie deficit, and increased physical activity can help individuals manage their weight in a healthy and sustainable way.
