1. What Exactly Is The Keto Diet?
The keto diet is a strategic eating plan designed to shift your body’s primary fuel source from glucose to ketones. Originally developed to manage specific types of childhood epilepsy, the ketogenic diet has now gained popularity as a weight-loss approach. Doctors may recommend it when other treatments don’t work, and people following a keto diet for epilepsy should do so under careful supervision by a healthcare professional.
When you drastically reduce your carbohydrate intake, your body enters a state called ketosis, where it starts burning fat for energy. This process results in the production of ketones, which become your body’s new fuel. For a diet of 2,000 calories, that translates to roughly 25–50 grams of carbohydrates, 150–180 grams of fat, and 50–100 grams of protein per day.
1.1 How Does Ketosis Work?
Ketosis works by restricting carbs, normally broken down into glucose for energy. According to research from the National Institutes of Health, when carbohydrate intake is reduced, the body turns to fat as its primary energy source, converting it into ketones. This metabolic shift, known as ketogenesis, typically begins 3 to 4 days after restricting carbs, as noted in the European Journal of Clinical Nutrition, compelling your body to burn stored fat.
1.2 What Are The Benefits of The Keto Diet?
While the primary reason many people turn to the keto diet is weight loss, it offers several other potential benefits. The keto diet has been shown to reduce appetite, making it easier to control calorie intake. Beyond weight management, some studies suggest that the keto diet may improve blood sugar control and cholesterol levels.
However, it’s essential to consult with a healthcare professional before starting any new diet, especially if you have underlying health conditions.
2. What Foods Can You Eat On The Keto Diet?
Navigating the keto diet means knowing which foods fit the bill. While it might seem restrictive at first, there’s a wide variety of delicious and nutritious options to choose from.
The key is to focus on foods high in healthy fats, moderate in protein, and very low in carbohydrates.
2.1 Meats and Poultry
Meats and poultry are staples in the keto diet due to their high-fat and low-carb content. Beef, pork, lamb, chicken, and turkey are all excellent choices. These foods provide essential protein and help you feel full and satisfied.
According to a study in BMC Medicine, consuming meat in moderation can be part of a balanced keto diet. However, eating too much meat regularly has been linked to health conditions such as heart disease and type 2 diabetes. It’s best to vary your protein sources and include other keto-friendly options like fish, eggs, and nuts.
Macronutrients per 3.5 ounces (100 g) in meat and poultry:
| Food | Fat (g) | Protein (g) | Carbs (g) |
|---|---|---|---|
| Chicken Breast | 3.6 | 30 | 0 |
| Ground Beef | 16 | 26 | 0 |
| Pork Chop | 9.7 | 27 | 0 |
2.2 Fish and Seafood
Fish and seafood are fantastic additions to a keto diet, offering a wealth of nutrients and healthy fats. Salmon, mackerel, tuna, and sardines are rich in omega-3 fatty acids, which are essential for brain health and reducing inflammation. Shellfish like shrimp, crab, and lobster are also great options.
Macronutrients per 3 ounces (85 g) in fish and seafood:
| Food | Fat (g) | Protein (g) | Carbs (g) |
|---|---|---|---|
| Salmon | 13 | 17 | 0 |
| Shrimp | 0.5 | 20 | 0.2 |
| Tuna | 5 | 25 | 0 |
According to the USDA FoodData Central, incorporating a variety of fish and seafood into your keto meal plan can significantly enhance your overall nutrient intake.
2.3 Non-Starchy Vegetables
Non-starchy vegetables are vital for a well-rounded keto diet, providing essential vitamins, minerals, and fiber. Leafy greens like spinach, kale, and lettuce are excellent choices, along with broccoli, cauliflower, zucchini, and bell peppers.
These vegetables are low in carbs and high in nutrients, making them perfect for maintaining good health while staying in ketosis.
Macronutrients per 3.5 ounces (100 g) in low-carb, high-fiber vegetables:
| Food | Fat (g) | Protein (g) | Carbs (g) | Fiber (g) |
|---|---|---|---|---|
| Spinach | 0.4 | 3 | 3.6 | 2.9 |
| Broccoli | 0.4 | 2.8 | 7 | 2.6 |
| Cauliflower | 0.3 | 1.9 | 5 | 2 |
According to a study published in Neurology, non-starchy vegetables also contain antioxidants that support overall well-being.
2.4 Eggs
Eggs are a versatile and affordable staple on the keto diet. Packed with protein and healthy fats, they are also very low in carbohydrates. Eggs can be prepared in countless ways, making them a convenient option for any meal.
Macronutrients per large egg:
| Nutrient | Amount (per egg) |
|---|---|
| Fat | 5 g |
| Protein | 6 g |
| Carbs | 1 g |
The American Journal of Clinical Nutrition has published research indicating that moderate egg consumption (up to one egg per day) is not associated with adverse health outcomes for most people.
2.5 High-Fat Dairy Products
High-fat dairy products can be included in a keto diet, but it’s essential to choose them wisely. Options like heavy cream, cheese, and butter are high in fat and low in carbs. Yogurt can keep you fuller for longer and provides beneficial probiotics for your gut.
However, it’s important to balance your dairy intake with plant-based foods. A study in The Lancet found that people who substituted carbs with animal products were more likely to die during the 25-year follow up than those who substituted plant-based options like nuts.
2.6 Nuts and Seeds
Nuts and seeds are nutritious, high-fat, and low-carb options perfect for keto dieters. Almonds, walnuts, chia seeds, flaxseeds, and sunflower seeds are all excellent choices. They are packed with fiber, vitamins, and minerals.
Macronutrients per 1 ounce (28 g) in nuts and seeds:
| Food | Fat (g) | Protein (g) | Carbs (g) | Fiber (g) |
|---|---|---|---|---|
| Almonds | 14 | 6 | 6 | 3.5 |
| Chia Seeds | 9 | 5 | 12 | 10 |
| Flaxseeds | 12 | 5 | 8 | 8 |
According to research in The American Journal of Clinical Nutrition, regular consumption of nuts and seeds is associated with a lower risk of heart disease and diabetes.
2.7 Avocados
Avocados are a keto superstar, celebrated for their high fat content and low carb count. A whole avocado contains about 17 grams of carbs, but 14 grams of that is fiber, leaving only 3 grams of net carbs. Avocados are also rich in vitamins and minerals, including potassium and B vitamins.
According to a study in the Journal of the American Heart Association, regular avocado consumption can help improve cholesterol levels and support heart health.
2.8 Berries
While most fruits are high in carbs, berries are a notable exception. Strawberries, blueberries, raspberries, and blackberries can be enjoyed in moderation on a keto diet.
They’re lower in carbs than other fruits and packed with antioxidants.
Macronutrients per 3.5 ounces (100 g) in berries:
| Food | Fat (g) | Protein (g) | Carbs (g) | Fiber (g) |
|---|---|---|---|---|
| Strawberries | 0.3 | 0.7 | 7.7 | 2 |
| Blueberries | 0.3 | 0.7 | 14.5 | 2.4 |
| Raspberries | 0.7 | 1.2 | 11.9 | 6.5 |
2.9 Oils
Healthy oils are a cornerstone of the keto diet, providing a pure source of fat without any carbs. Olive oil, avocado oil, coconut oil, and MCT oil are all excellent choices.
Olive oil, in particular, has been shown to have numerous health benefits. A study in the International Journal of Molecular Sciences suggests that the phenolic compounds in olive oil can protect against heart disease and cancer.
Some oils, like avocado, sunflower, and rice bran oil, are more stable when cooking at a high heat.
2.10 High-Cocoa Chocolate
For those with a sweet tooth, high-cocoa chocolate (70% cocoa or more) can be a keto-friendly treat. It’s a good source of antioxidants, including flavanols, which can improve heart health, according to research in The American Journal of Clinical Nutrition.
A 3.5-ounce portion (100 g) of 70% cocoa chocolate contains approximately 43 g of carbohydrates, 7 g of fiber, 47 g of fat, and 7 g of protein.
2.11 Coffee and Tea Without Sugar
Coffee and tea without sugar are carb-free beverages that can be enjoyed on the keto diet. Both are linked to a large range of health benefits, including living a longer and healthier life, according to The New England Journal of Medicine.
These benefits are found for both caffeinated and decaffeinated versions, so if you’re sensitive to caffeine or it’s late in the day, choose a decaf option.
3. What Foods Should You Limit Or Avoid On Keto?
While the keto diet allows for a variety of foods, it’s also important to know which ones to limit or avoid. These foods are typically high in carbohydrates and can kick you out of ketosis.
3.1 Grains
Grains like wheat, rice, oats, and corn are high in carbohydrates and should be avoided on a keto diet. This includes bread, pasta, cereal, and other grain-based products.
3.2 Sugary Foods
Sugary foods such as soda, juice, candy, and pastries are very high in carbs and should be strictly avoided. Even natural sweeteners like honey and maple syrup should be used sparingly.
3.3 Starchy Vegetables
Starchy vegetables like potatoes, sweet potatoes, corn, and peas are high in carbohydrates and should be limited on a keto diet.
3.4 Legumes
Legumes like beans, lentils, and chickpeas are high in carbs and should be avoided on a keto diet.

Fruits like bananas, grapes, mangoes, and pineapples are high in sugar and should be limited on a keto diet. Berries are a better option due to their lower carb content.
3.6 Low-Fat Dairy Products
Low-fat dairy products often have added sugars to compensate for the lack of fat. These added sugars can increase the carb content, making them less suitable for a keto diet.
4. How Can You Ensure You’re Getting Enough Fiber?
One of the challenges of the keto diet is ensuring you get enough fiber. Many high-fiber foods, like whole grains and legumes, are also high in carbs and should be avoided. However, there are plenty of low-carb, high-fiber options to choose from.
4.1 Non-Starchy Vegetables
Non-starchy vegetables like spinach, kale, broccoli, cauliflower, and zucchini are excellent sources of fiber on a keto diet.
4.2 Nuts and Seeds
Nuts and seeds like almonds, chia seeds, flaxseeds, and sunflower seeds are high in fiber and healthy fats.
4.3 Avocados
Avocados are a great source of fiber, with about 14 grams of fiber in a whole avocado.
4.4 Berries
Berries like strawberries, blueberries, and raspberries are relatively low in carbs and high in fiber.
4.5 Fiber Supplements
If you’re struggling to get enough fiber from food alone, you can consider taking a fiber supplement. Psyllium husk and methylcellulose are common fiber supplements that are low in carbs.
