The keto diet is a high-fat, low-carb, low-to-moderate protein diet. It is a metabolic state in which your body is consistently using and burning an alternative fuel called ketones. To produce ketones and enter ketosis, the liver triggers a process called ketogenesis. This is done by limiting carb consumption. The keto diet is simple but may be difficult to adapt to at first. The results of this keto journey depend on the person. High-quality studies on the keto diet have found that it consistently leads to the same amount or slightly more weight loss than many other popular diets. The keto diet can also help with many common conditions that people struggle with today, including heart disease, type 2 diabetes, and Alzheimer's disease.

What You'll Learn
Know what foods to eat and avoid
Knowing what foods to eat and what to avoid is the most important factor when starting the keto diet. Here's a breakdown of the different meat, seafood, vegetables, fruits, dairy products, fats, and oils you can enjoy.
Meat and Seafood
Chicken (dark meat is ideal), tuna (canned tuna is OK, and oil-packed is best for the fats), and other fatty cuts of meat are good sources of protein and fat. Remember, choosing organic, grass-finished beef, heritage pork, and free-range chicken are always optimal choices.
Vegetables
Vegetables are an important source of nutrients on a keto diet, but some contain a higher percentage of carbs and should be avoided or limited. Root vegetables like beets, carrots, and potatoes are higher in carbs and starches and can take your body out of ketosis. Instead, opt for dark, leafy greens such as lettuce and spinach.
It's important to note that cooking vegetables can increase the carb count. Before preparing your meals, consider the difference in carbs for raw versus cooked vegetables.
Fruits
Fruits are often seen as the enemy of a keto diet, but some can be eaten in moderation. Avocados, raspberries, blackberries, and other low-glycemic impact berries are good choices. Serving size is also crucial when it comes to fruit. It's easy to eat a whole bowl of raspberries, but that can quickly add up to a day's worth of carbs.
Dairy Products
Dairy products are high-fat, low-carb protein sources that are perfect for a keto lifestyle. Ghee (clarified butter) is a great option, but avoid evaporated and dry milk products as they have higher carb counts. Drink milk in moderation as it contains lactose, and always opt for full-fat dairy.
Fats and Oils
Fat is central to a truly ketogenic diet, typically making up 70-80% of daily calories. It's important to consume high-quality fats, avoiding deep-fried, empty calories. Good sources of fats include oils such as avocado oil, coconut oil, extra virgin olive oil, and MCT oil, as well as nuts like Brazil nuts, pecans, and macadamia nuts, and seeds like chia, flax, hemp, and sunflower seeds.
Nuts and seeds are easy to overdo, so it's wise to measure your serving size to ensure you're within a healthy range of carbs. While they are lower in carbs, they still contain enough to take you out of ketosis if consumed in large amounts.

Prepare for a high-fat diet
The keto diet is a high-fat, low-carb diet that involves getting 70-80% of your daily calories from fat. This can be a big change for many people, so it's important to prepare yourself for this new way of eating. Here are some tips to help you get ready for a high-fat diet:
- Gradually increase your fat intake: Start making small adjustments to your diet by ordering a burger on lettuce leaves instead of a bun, or choosing green veggies instead of fries. Cook with more healthy oils like olive or avocado oil, and opt for fattier cuts of meat.
- Choose the right fats: Not all fats are created equal. Prioritize healthy, high-quality fats like avocado, extra virgin olive oil, nuts, seeds, and fatty fish like salmon and mackerel. These foods will provide your body with the nutrients it needs while helping you stay in ketosis.
- Be mindful of portion sizes: Nuts, seeds, and fatty meats can be high in calories, so it's important to watch your portion sizes. Measure out your servings to make sure you're staying within a healthy range.
- Get creative with your meals: Eating a high-fat diet doesn't have to be boring. Look for keto-friendly recipes that include a variety of delicious, nutritious foods. Experiment with different ingredients and cooking methods to find what works best for you.
- Prepare your kitchen: Stock your kitchen with keto-friendly foods and get rid of any high-carb temptations. Fill your fridge with leafy greens, avocados, high-fat dairy, and healthy oils.
- Be patient with yourself: Adjusting to a high-fat diet can take time, and it's normal to experience some discomfort at first. Go slowly and listen to your body. If you're feeling overwhelmed, remind yourself of the benefits of the keto diet, such as weight loss and improved health.

Understand the importance of protein
Protein is an essential macronutrient that plays a crucial role in various bodily functions. It is made up of smaller units called amino acids, nine of which are essential, meaning our bodies cannot produce them, and we must obtain them from our diet. Here are some key reasons why protein is important:
- Muscle growth and repair: Protein is necessary for muscle repair and growth. Consuming adequate protein helps prevent muscle loss and, when combined with resistance training, promotes muscle growth.
- Supporting healthy skin, hair, and nails: Protein is crucial for maintaining healthy skin, hair, and nails. It provides the body with the building blocks needed to create and repair these tissues.
- Creation of hormones and enzymes: Many important hormones, such as insulin and growth hormones, are proteins. Most enzymes in the human body are also proteins, and a continuous supply of amino acids is needed to produce these vital compounds.
- Maintaining healthy bones and joints: Protein is essential for maintaining healthy bones and joints, as it provides the structural framework for these tissues.
- Supporting immune function: Protein plays a vital role in supporting our immune system, helping to fight off infections and diseases.
- Maintaining pH of blood and bodily fluids: Protein helps regulate the pH of our blood and bodily fluids, maintaining a stable and balanced internal environment.
Potential issues with low protein intake
Not consuming enough protein can lead to various issues, including decreased muscle mass and struggles with weight management. It is important to ensure adequate protein intake, especially when following a ketogenic diet, to support overall health and well-being.
Protein intake on a ketogenic diet
The ideal protein consumption on a ketogenic diet can vary depending on individual factors, such as activity level, age, and health status. However, as a general guideline, it is recommended to consume between 1.6 g/kg and 3 g/kg of body weight of protein per day. This range takes into account different expert opinions and recommendations, with some advocating for lower protein intake to promote longevity, while others suggest higher protein intake for weight loss and muscle maintenance.
Those who may require a higher protein intake on a ketogenic diet include individuals looking to maintain muscle mass while losing weight, those at risk of slow wound healing, older adults aiming to remain active and healthy, and people with type 2 diabetes or cardiovascular risk factors.
It is important to note that while protein intake is crucial for muscle growth and repair, excessive protein consumption is not necessary. Research suggests that even elite bodybuilders can benefit from an upper limit of 0.75 g/lb (1.65 g/kg) of protein intake. Additionally, more advanced trainees may require less protein than novice athletes.
Keto-friendly protein sources
When following a ketogenic diet, it is important to choose healthy protein sources. Some recommended options include:
- Meat, poultry, and seafood
- Eggs
- Cheese and other dairy products
- Nuts and seeds
- Tofu and soy-based products
- Full-fat dairy
- Collagen or whey protein supplements
In summary, protein is essential for various bodily functions, and adequate intake is crucial for overall health and well-being. When following a ketogenic diet, it is important to prioritize protein intake and choose healthy protein sources to support your health goals.
