The ketogenic diet (or keto diet, for short) is a very low-carbohydrate, high-fat diet that offers many health benefits. In fact, over 20 studies show that this type of diet shares many similarities with the Atkins and low-carb diets which can help you lose weight and improve your health. Ketogenic diets drastically reduces carbohydrate intake and puts your body into a metabolic state called ketosis. During ketosis, your body becomes incredibly efficient at burning fat for energy. It also turns fat into ketones in the liver, which can supply energy for the brain.
Keto diets can cause massive reductions in blood sugar and insulin levels which is closely linked to type 2 diabetes, pre-diabetes and metabolic syndrome.
Eating fewer carbs can have impressive health benefits as most low-carbs foods are healthy, nutritious and incredibly delicious. What’s more, they’re highly diverse, covering many major food categories, including meats, fish, vegetables, fruits, and dairy products.
Studies have now shown that a healthy, low-carb diet based on real foods can help you lose weight and improve your health as well produce benefits for a wide variety of different health conditions:
Heart disease: The ketogenic diet can improve risk factors like body fat, HDL cholesterol levels, blood pressure and blood sugar.
Cancer: The diet is currently being used to treat several types of cancer and slow tumor growth.
Alzheimer's disease: The keto diet may reduce symptoms of Alzheimer's disease and slow its progression.
Epilepsy: Research has shown that the ketogenic diet can cause massive reductions in seizures in epileptic children.
Parkinson's disease: One study found that the diet helped improve symptoms of Parkinson's disease.
Polycystic ovary syndrome: The ketogenic diet can help reduce insulin levels, which may play a key role in polycystic ovary syndrome.
Brain injuries: One animal study found that the diet can reduce concussions and aid recovery after brain injury.
Acne: Lower insulin levels and eating less sugar or processed foods may help improve acne.
Keto diets exclude the following foods with high carbohydrate content from their diets:
Sugary foods: Soda, fruit juice, smoothies, cake, ice cream, candy, etc.
Grains and starches: Wheat-based products, rice, pasta, cereal, etc.
Fruit: All fruit, except small portions of berries like strawberries.
Beans or legumes: Peas, kidney beans, lentils, chickpeas, etc.
Root vegetables and tubers: Potatoes, sweet potatoes, carrots, parsnips, etc.
Low-fat or diet products: These are highly processed and often high in carbs.
Some condiments or sauces: These often contain sugar and unhealthy fat.
Unhealthy fats: Limit your intake of processed vegetable oils, mayonnaise, etc.
Alcohol: Due to their carb content, many alcoholic beverages can throw you out of ketosis.
Sugar-free diet foods: These are often high in sugar alcohols, which can affect ketone levels in some cases. These foods also tend to be highly processed.
