The Ketogenic Diet: A Detailed Beginner’s Guide to Keto
The ketogenic diet (or keto diet, for short) is a low-carb, high-fat diet that offers many health benefits.
In fact, over 20 studies show that this type of diet can help you lose weight and improve your health (1Trusted Source).
Ketogenic diets may even have benefits against diabetes, cancer, epilepsy and Alzheimer’s disease (2Trusted Source, 3Trusted Source, 4Trusted Source, 5Trusted Source).
Here is a detailed beginner’s guide to the keto diet.
There are several versions of the ketogenic diet, including:
- 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 (1Trusted Source).
- 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.
However, only the standard and high-protein ketogenic diets have been studied extensively. Cyclical or targeted ketogenic diets are more advanced methods and primarily used by bodybuilders or athletes.
The information in this article mostly applies to the standard ketogenic diet (SKD), although many of the same principles also apply to the other versions.
Any food that is high in carbs should be limited.
Here is a list of foods that need to be reduced or eliminated on a ketogenic diet:
- Sugary foods: Soda, fruit juice, smoothies, cake, ice cream, candy, etc.
- Grains or 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.
You should base the majority of your meals around these foods:
- Meat: Red meat, steak, ham, sausage, bacon, chicken and turkey.
- Fatty fish: Such as 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.
It is best to base your diet mostly on whole, single-ingredient foods.
