The ketogenic diet is a low-carbohydrate, high-fat diet that has become popular among humans. The diet has been linked to various health benefits, including weight loss and improved brain function. As a result, some people have considered putting their cats on a ketogenic diet to help them live longer and healthier lives. Cats, as obligate carnivores, have high protein requirements and are sensitive to the development of hepatic lipidosis during marked increases in fatty acid oxidation. They must eat meat because their bodies cannot produce certain amino acids, vitamins, and minerals on their own. While a ketogenic diet may be beneficial for cats, it is important to note that cats do not rely on ketones for energy like humans do and that a high-fat diet could lead to significant health risks.

Ketogenic diets for cats are low-carbohydrate, high-protein and high-fat
The ketogenic diet is a low-carbohydrate, high-protein, and high-fat diet that has become popular for both humans and cats. Cats, as obligate carnivores, require a meat-based diet and have no nutritional need for vegetables or carbohydrates.
A ketogenic diet for cats typically involves feeding them a raw, species-appropriate diet with minimal to no carbohydrates. This can include high-quality lean proteins such as beef, chicken, fish, turkey, and organ meats. Cats on a ketogenic diet may also be introduced to a healthy amount of fat, as they rely on fats and proteins for energy.
The benefits of a ketogenic diet for cats are believed to include weight management, improved brain function, a lower risk of cancer, and better management of age-related neurological disorders. It is also thought to help manage diabetes and reduce the risk of heart and skin disease, gastrointestinal and urinary issues.
However, it is important to note that a ketogenic diet may not be suitable for all cats, especially those with liver, kidney, or pancreatic issues. Additionally, cats on a ketogenic diet should still have their nutritional requirements met, including essential amino acids, vitamins, and minerals.
There are two types of ketogenic diets: one based on long-chain triglycerides (LCT) and another based on medium-chain triglycerides (MCT). The MCT diet is currently the only one implemented in veterinary medicine, as it has better absorption and faster transport of fatty acids to the liver. It also requires less fat and allows for a higher proportion of protein and carbohydrates, minimizing the risk of pancreatitis or hepatic lipidosis.

Cats are obligate carnivores and require meat in their diet
Cats are obligate carnivores, meaning they require meat in their diet and need few carbohydrates. In the wild, cats usually prey on small animals, such as mice and birds. As pets, cats may not have the opportunity to hunt for their own food, so owners must mimic the high-protein, low-carbohydrate diet their cat would naturally eat in the wild.
Cats have a shorter digestive tract than most mammals because raw meat is more rapidly digested. Their gastrointestinal tracts and metabolism have adapted to eating meat, and they cannot digest plant material well. Cats require essential nutrients that only meat can provide, such as amino acids, vitamins, and minerals that their bodies cannot produce on their own. If a cat is fed a vegetarian-based diet, her body will begin breaking down her own muscles and organs for energy.
Cats have a very efficient metabolic system, which is part of what makes them such good predators. They do a straight protein (amino acid)/fat conversion to glucose, which is used for energy. Cats do not rely on ketones, but they still rely on fats and proteins for energy, and much more efficiently than humans.
While it is possible to keep dogs healthy on a plant-based diet, a vegan diet is not appropriate for cats. Cats are unable to synthesise taurine, an amino acid that can only be found in animal sources such as meat and milk.
It is worth noting that a staggering 50% of the world's cat population is obese. This is largely due to the convenience of kibble-in-a-bag food, which is often high in carbohydrates. A ketogenic diet is a low-carb diet that may be suitable for cats, but it is important to consult a nutritional expert to ensure the diet meets all of a cat's needs.

The ketogenic diet may reduce the risk of cancer in cats
The ketogenic diet is a low-carbohydrate, high-fat, and high-protein diet that has become popular among humans. It involves a period of ketosis, where the body's metabolic system stops relying on carbohydrates and instead relies on fat and protein.
Cats, as obligate carnivores, have high protein requirements and are sensitive to hepatic lipidosis development during marked increases in fatty acid oxidation. A ketogenic diet for cats would therefore be high in protein and fat, with a lower proportion of carbohydrates.
The ketogenic diet has been proposed as a possible nutritional approach to cancer treatment in cats. Cancer is a metabolic disease, and a ketogenic diet can target the metabolic characteristics of cancer, starving cancer cells by restricting carbohydrates and promoting the production of ketones. This is because cancer cells need much more sugar than normal cells to grow and prosper.
While there is some evidence to support the use of a ketogenic diet in cancer treatment for cats, it is important to note that this is still an emerging area of veterinary science. The use of a ketogenic diet in cats with cancer has not been extensively studied, and it is presumptive to claim that it is without risk. As such, it is important to consult a veterinarian before making any dietary changes for a cat with cancer.

Cats on a high-carb diet may be at risk of obesity, diabetes, and heart disease
Cats are obligate carnivores, meaning they require meat in their diet as their bodies are unable to produce certain amino acids, vitamins, and minerals on their own. Meat is the only source of these essential nutrients. In the wild, cats eat the belly of their prey, which contains carbohydrates. However, domestic cats are not designed to consume a high-carbohydrate diet. High-carb diets in cats can lead to obesity, which increases the risk of diabetes, heart disease, skin disease, gastrointestinal issues, and even certain types of cancer.
Obesity in cats is a growing problem, with around 50% of the world's cat population considered obese. This is often due to the convenience of kibble-in-a-bag food, which often contains inappropriate ingredients, such as grains with high carbohydrate content. When these carb-dense foods are freely available to cats, they can easily gain weight and develop health issues. Obesity can increase the risk of various diseases, including diabetes, arthritis, and heart disease.
Diabetes in cats is often associated with obesity and high-carb diets. When cats consume excessive carbohydrates, it can lead to insulin resistance and Type 2 diabetes. Lowering the carbohydrate level in a cat's diet can help manage diabetes and, in some cases, even eliminate the need for insulin. Therefore, it is crucial to consider portion control and limit the number of carbohydrates in a cat's diet to maintain a healthy weight and reduce the risk of obesity-related health issues.
While a ketogenic diet has been proposed for cats, it is important to note that this approach has not been extensively studied in veterinary medicine. The ketogenic diet is based on either long-chain triglycerides (LCT) or medium-chain triglycerides (MCT). The MCT diet has shown promising results in epileptic dogs, but its benefits for cats are still anecdotal. The LCT ketogenic diet, which includes large amounts of fatty meats, oils, and processed foods, may pose health risks for cats, especially if their amino acid and gluconeogenetic needs are not met.
Instead of following trendy human diets like keto, it is recommended that cat owners focus on providing a balanced diet with appropriate protein sources, such as lean meats, and ensuring portion control to maintain a healthy weight. Consulting with a veterinarian is essential to determine the best dietary approach for a cat's individual needs and to avoid potential health risks associated with certain diets.

The MCT ketogenic diet is the only type currently implemented in veterinary medicine
There are two basic types of ketogenic diets: one based on long-chain triglycerides (LCT) and another based on medium-chain triglycerides (MCT). The LCT diet involves a high-fat, low-carbohydrate meal plan, which is similar to the popular human keto diet. Cats, being obligate carnivores, require meat in their diet as they are unable to produce certain amino acids, vitamins and minerals on their own.
The LCT ketogenic diet has been studied extensively in relation to tumour research. Studies indicate that tumour cells have increased glucose consumption, which is addressed by the LCT diet, which induces oxidative metabolism and limits glucose consumption. However, the use of the LCT ketogenic diet in dogs and cats undergoing treatment or recovery for tumours has not been described in existing veterinary scientific literature. Therefore, it is presumptive to claim that the use of an LCT ketogenic diet is without risk.
The MCT ketogenic diet, on the other hand, is designed to improve the shortcomings of the LCT diet. The MCT diet is based on the concentration of medium-chain fatty acids that are able to derive ketone bodies. The main advantage of the MCT diet is better absorption and faster transport of fatty acids to the liver, avoiding the thoracic duct and chylomicrons formation, resulting in faster β-oxidation and the formation of ketone bodies. The MCT diet requires less fat to achieve a beneficial concentration of ketone bodies: just 10% of energy must be supplied through MCT. A lower proportion of fat and a higher proportion of protein and carbohydrates in the diet contribute to better palatability and minimize the risk of pancreatitis or hepatic lipidosis, which is contrary to the LCT diet.
