Dr. Eric Berg's ketogenic diet is a low-carb, high-fat, and moderate-protein eating plan that promotes weight loss and overall health and well-being. The keto diet, originally developed in the 1920s as a treatment for epilepsy, involves reducing carbohydrate intake and increasing healthy fat consumption to shift the body's metabolism from relying on glucose to burning fat for fuel. This metabolic state is known as ketosis, where the body uses ketones, produced by the liver, as an alternative energy source. Dr. Berg's approach, called Healthy Keto, emphasizes nutrient-dense, whole foods, including organic vegetables, high-quality proteins, and healthy fats. He also provides recipe books and meal plans to make the keto diet accessible and tasty, with desserts like cheesecake and peanut butter cookies.

What You'll Learn
Healthy fats like olive oil, avocado, and nuts
The keto diet is a high-fat, moderate-protein, and low-carbohydrate eating plan. Healthy fats are an essential part of the keto diet, and olive oil, avocado, and nuts are great sources of these.
Olive oil is a well-known healthy fat and a good choice for the keto diet. It can be used in cooking, as a salad dressing, or added to hot drinks. Avocado oil is also a recommended healthy fat for keto, with similar uses to olive oil. Avocados themselves are also a popular food choice these days and are keto-friendly. They are low in net carbohydrates and high in healthy fats, making them a great fit for the keto diet. Avocados are also packed with essential vitamins and minerals, making them a nutrient-dense food. You can eat one to two avocados per day as part of a keto diet, but be sure to consider the total fat and carb content of your daily meals to stay within the ketogenic range.
Nuts are a great source of healthy fats and can be enjoyed as part of a keto diet, but it's important to pay attention to serving sizes and choose lower-carb options. Pecans, for example, contain the least amount of carbs out of all nuts, with just one gram of net carbs per ounce. Brazil nuts are another good choice, with just two grams of carbs per ounce. Hazelnuts are also a healthy option, with only two grams of net carbs per ounce and various health benefits, such as reducing inflammation and regulating blood pressure. Almonds are another good choice, with just three grams of net carbs per ounce and high levels of healthy fats and antioxidants. Although cashews have the highest amount of carbs of the nuts listed here, they can still be enjoyed on a keto diet in moderation as they are rich in essential nutrients.

High-quality proteins such as pasture-raised meats and eggs
The ketogenic diet is a high-fat, moderate-protein, and low-carbohydrate eating plan designed to shift your metabolism from relying on glucose to burning fat for fuel. When your body is in a state of ketosis, it uses fat as its primary energy source.
High-quality protein sources are essential on the keto diet, and pasture-raised meats and eggs are excellent choices. Pasture-raised meats include grass-fed beef, poultry, and game meats. These animals are raised on organic pastures, where they feed on pesticide-free grass and plants. By choosing organically raised meats, you benefit from increased omega-3 fatty acids and reduced bad fats. Additionally, organic meats are free from growth hormones and antibiotics, which are commonly found in conventionally raised animals.
Pasture-raised eggs are another important source of high-quality protein on the keto diet. These eggs come from chickens that roam and feed in open pastures. By prioritizing pasture-raised eggs, you can be confident in the ethical treatment of the chickens and the nutritional quality of the eggs they produce.
When incorporating pasture-raised meats and eggs into your keto diet, aim for moderate portions to support muscle function and hormonal balance. Remember that while protein is necessary, excessive consumption, especially from very lean sources, can raise insulin levels and interfere with ketosis. Therefore, it is crucial to balance your protein intake with healthy fats and low-carb vegetables to maintain optimal ketosis and overall health.

Non-starchy vegetables like leafy greens and broccoli
Dr. Berg's keto diet is a low-carb meal plan that pushes the body into ketosis, a metabolic state of fat-burning. The diet focuses on reducing carbohydrates and increasing fat intake to achieve ketosis. It is recommended to consume 7 to 10 cups of vegetables per day, and individuals with certain digestive disorders may benefit from limiting high-fiber vegetables to minimize the risk of gastrointestinal side effects.
It is important to avoid starchy vegetables such as sweet potatoes, carrots, beets, and corn, as they are carb-heavy and can interfere with your ability to achieve and maintain ketosis. While most fruits are not suitable for keto, fiber-rich berries such as blackberries, blueberries, raspberries, and black currants can be enjoyed in moderation without affecting ketosis.
In addition to non-starchy vegetables, healthy fats form the foundation of Healthy Keto. It is recommended to prioritize unprocessed, nutrient-dense sources such as extra virgin olive oil, avocados, coconut oil, nuts, seeds, grass-fed butter, and fatty fish like salmon or mackerel. These nutritious fats not only support ketosis but also provide important fat-soluble vitamins and anti-inflammatory benefits.
Protein should also be included in the keto diet, with moderate amounts of high-quality proteins like grass-fed meat, wild-caught fatty fish, and pasture-raised eggs to support muscle function and hormonal balance. Carbohydrate intake should be kept low and come primarily from nutrient-dense, non-starchy vegetables, providing essential vitamins and minerals while maintaining ketosis.

Low-carb beverages—water, tea, and black coffee
Staying hydrated is essential when following a keto diet. Water is the most important drink, and it can be enjoyed in several ways: plain, mineral, sparkling, or lemon water. These options are all keto-friendly and provide hydration without disrupting fat-burning processes.
Black coffee is another beverage that can be consumed on a keto diet. It contains no calories and may promote alertness. However, it is important to avoid adding sugar or flavoured coffee creamers, as these can quickly break a fast and take you out of ketosis. If you want to add a little extra to your black coffee, consider a small amount of healthy fat such as grass-fed butter or medium-chain triglycerides (MCT) oil. This variation is known as bulletproof coffee.
Tea, specifically green and black tea, as well as herbal tea varieties, are also keto-friendly. They provide health-promoting antioxidants while keeping your body in a metabolic fasting state. Tea can be enjoyed hot or cold and is a perfect drink to sip throughout the day without interfering with your keto goals.

Keto-friendly substitutes when eating out—swap fries for salad
The ketogenic diet is a low-carb, high-fat, and moderate-protein eating plan that promotes fat burning and overall health and well-being. While it may seem challenging to stick to a keto diet when eating out, there are plenty of keto-friendly substitutes available. Here are some tips for swapping fries for salad and making healthier choices while dining out:
Check the Menu in Advance: Before visiting a restaurant, take a look at their menu online. This way, you can plan your order and identify any potential keto-friendly options. Knowing your choices beforehand can help you make informed decisions and stick to your keto diet.
Ask for Substitutions: Don't be afraid to request substitutions or modifications to your meal. For example, instead of ordering fries as a side dish, ask for a side salad or non-starchy vegetables like broccoli or zucchini. Restaurants are often accommodating, especially when you clearly communicate your dietary needs and preferences.
Skip the Bun: If you're ordering a burger or sandwich, consider forgoing the bun. You can enjoy the patty with a knife and fork alongside your salad or vegetables. This simple swap reduces the carbohydrate load of your meal.
Dressings and Sauces: Request dressings and sauces on the side. These condiments can sometimes contain hidden sugars and carbohydrates. By having them on the side, you can control the amount added to your salad or dish, ensuring it aligns with your keto diet.
Bring Your Own Keto Dish: If you're attending a social gathering or potluck, offer to bring a dish to share. Prepare a keto-friendly option that aligns with your dietary needs and introduces others to delicious keto cuisine. This way, you know there will be at least one dish you can enjoy without compromising your keto journey.
Keto-Friendly Fries Alternatives: If you're craving fries, there are keto-friendly alternatives you can make at home or order at certain restaurants. Rutabaga fries, for instance, are a popular choice. They are made with rutabagas (also known as swedes or yellow turnips), which have a crispy texture similar to potatoes but with fewer carbohydrates. You can also experiment with other root vegetables like jicama or kohlrabi, which have a more neutral taste. Additionally, there are recipes for keto fries made with almond flour or a combination of coconut and almond flour that mimic the taste and texture of traditional fries.
