The ketogenic diet is a low-carb, high-fat diet that has various similarities with the Atkins and other low-carb diets.

This diet involves drastically reducing your carbohydrate consumption and replacing it with fat. The reduction of carbs will put your body into a metabolic state called ketosis.

Once this happens, your body becomes much more efficient in burning fat for energy. It also turns fat into ketones in the liver, which has been shown to supply energy for the brain.

Ketogenic diets can see huge reductions in blood sugar and insulin levels. This, along with the increased ketones, has numerous health benefits.

• Meat: Red meat, steak, ham, sausage, bacon, chicken and turkey.
• Fatty fish: salmon, trout, tuna and mackerel.
• Eggs: Look for pastured or omega-3 whole eggs.
• Butter and cream: Look for grass-fed when possible.
• Cheese: Unprocessed cheese (cheddar, goat, cream, blue or mozzarella).
• Nuts and seeds: Almonds, walnuts, flax seeds, pumpkin seeds, chia seeds, etc.
• Healthy oils: Primarily extra virgin olive oil, coconut oil and avocado oil.
• Avocados: Whole avocados or freshly made guacamole.
• Low-carb veggies: Most green veggies, tomatoes, onions, peppers, etc.
• Condiments: You can use salt, pepper and various healthy herbs and spices.

You should always try to select grass-fed, pasture-raised and organic foods. 

• High-sugar foods: Soda, fruit juice, smoothies, cake, ice cream, sweets
• Grains or starches: Wheat-based products, rice, pasta, cereal
• Fruit: All fruit, except small portions of berries like strawberries.
• Beans or legumes: Peas, kidney beans, lentils, chickpeas
• Root vegetables: Potatoes, sweet potatoes, carrots, parsnips
• Low-fat or diet products: They are usually highly processed and high in carbs.
• Various condiments: They usually contain sugar and unhealthy fat.
• Unhealthy fats: Limit your consumption 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 may affect ketone levels. They’re usually highly processed.

There are different types of Keto diet:

• Standard ketogenic diet (SKD): This is a very low-carb, moderate-protein and high-fat diet. It typically contains 75% fat, 20% protein and only 5% carbs (1).
• Cyclical ketogenic diet (CKD): This diet involves periods of higher-carb refeeds, such as 5 ketogenic days followed by 2 high-carb days.
• Targeted ketogenic diet (TKD): This diet allows you to add carbs around workouts.
• High-protein ketogenic diet: This is similar to a standard ketogenic diet, but includes more protein. The ratio is often 60% fat, 35% protein and 5% carbs.
