The ketogenic diet is a high-fat, low-carb, and moderate-protein diet. The diet aims to force the body into a metabolic state called ketosis, where the body uses fat for energy instead of carbohydrates. This diet has gained popularity as a weight-loss method and has been shown to be effective in promoting weight loss, though it may be no more effective than other weight-loss diets.
The keto diet is restrictive, and planning is required to ensure success. There are many keto-friendly options available, including meat, poultry, fish, eggs, and non-starchy vegetables.

What You'll Learn
Keto-friendly foods
A ketogenic diet is a low-carb, high-fat diet that can help with weight loss and improve health. Here is a detailed guide to keto-friendly foods.
Animal Proteins
Fish and shellfish are keto-friendly. Salmon and other fish are carb-free and rich in B vitamins, potassium, and selenium. Meat and poultry are also staple foods on the keto diet as they contain no carbs and are rich in B vitamins and minerals.
Eggs
Eggs are an extremely healthy protein source as they contain less than 1 gram of carbs and about 6 grams of protein. They can also trigger hormones that increase feelings of fullness. It is important to eat whole eggs as most of an egg's nutrients are found in the yolk.
Dairy and Dairy Alternatives
Cheese is a great fit for the keto diet as it is low in carbs and high in fat. Plain Greek yogurt and cottage cheese are also nutritious, high-protein foods that can be eaten in moderation on keto. Cream and half-and-half are also very low in carbs and high in fat, making them ideal for keto. Unsweetened plant-based milk such as soy, almond, and coconut milk are also keto-friendly.
Green Leafy Vegetables
Green leafy veggies are extremely low in carbs and rich in vitamins, minerals, and antioxidants. In particular, dark leafy greens like spinach, kale, and collard greens are packed with vitamin K and iron.
High-Fat Veggies
Avocados and olives are unique among vegetables as they are fairly high in fat and low in net carbs. Avocados also contain fiber.
Other Non-Starchy Vegetables
Low-carb veggies make great substitutes for high-carb foods. For instance, cauliflower can be turned into cauliflower rice or mashed cauliflower, and spaghetti squash serves as a natural alternative to spaghetti, and low-carb root veggies such as jicama and turnips make great substitutes for roasted potatoes or french fries.
Other Plant-Based Foods
Nuts and seeds are healthy, high in fat, and low in carbs. Berries, particularly raspberries and strawberries, are also low in carbs and high in fiber. Dark chocolate and cocoa powder are also keto-friendly, but it is important to choose dark chocolate that contains a minimum of 70% cocoa solids.
Oils
Olive oil, coconut oil, avocado oil, butter, and ghee are good fats to include in the keto diet.
Beverages
Unsweetened coffee, tea, and sparkling water are good keto-friendly beverage options.

Weight loss with keto
The keto diet is a high-fat, low-carbohydrate diet that has gained popularity as a weight loss method. It first surfaced in the 1920s as a way to help with conditions like epilepsy and diabetes. Today, it is often used as a weight loss strategy.
The keto diet is highly restrictive, as it requires a drastic reduction in carbohydrate intake. In a typical keto diet, fats make up 60% to 80% of daily calories, proteins make up 15% to 20%, and carbs are restricted to no more than 50 grams. This shift in macronutrient ratios forces the body to use fat as its primary fuel source instead of glucose, which is known as ketosis.
Research shows that the keto diet can be effective for weight loss. One review found that following a very low-carb, ketogenic diet resulted in slightly more weight loss than a low-fat diet. Additionally, the keto diet can lead to reductions in diastolic blood pressure and triglyceride levels. It is also particularly effective for people with type 2 diabetes, as it can help lower blood sugar and improve insulin sensitivity.
However, the keto diet may not be suitable for everyone. It can be challenging to stick to due to its restrictive nature, and it may not be safe for those with certain health conditions. Some people may also experience side effects when starting the keto diet, such as "keto flu," which includes symptoms like headaches, weakness, irritability, and digestive issues.
To follow the keto diet for weight loss, it is important to base meals around high-fat, low-carb foods. This includes meat, fatty fish, eggs, butter, nuts, healthy oils, avocados, and low-carb vegetables. It is also crucial to monitor carbohydrate intake and stay within the recommended range of 20 to 50 grams of carbs per day to achieve and maintain ketosis.
In conclusion, the keto diet can be an effective strategy for weight loss, but it requires strict adherence to a low-carb, high-fat diet. It offers various health benefits, particularly for those with type 2 diabetes. However, it may not be suitable or safe for everyone, and it is important to consult a healthcare professional before starting any new diet.

Health benefits of keto
The ketogenic diet is a high-fat, low-carb diet that has been linked to several health benefits. Here are some of the most notable health benefits of the keto diet:
Weight Loss
The keto diet is well-known for its weight loss benefits. By reducing carbohydrate intake and increasing fat consumption, the body enters a state of ketosis, where it burns fat for energy instead of carbohydrates. This leads to effective weight loss, even without intentional calorie restriction.
Improved Heart Health
The keto diet has been shown to improve heart health by reducing total cholesterol, lowering triglyceride levels, and increasing HDL ("good") cholesterol. Lowering cholesterol can reduce the risk of cardiovascular disease. Additionally, the keto diet's positive impact on weight loss and blood pressure also contributes to improved heart health.
Blood Sugar Control and Diabetes Management
The keto diet is effective in lowering blood sugar and insulin levels, which is crucial for managing type 2 diabetes and prediabetes. The reduction in carbohydrate intake means less sugar in the bloodstream, leading to better blood sugar control. In some cases, individuals with diabetes may need to reduce their insulin dosage or medication as a result of the keto diet.
Reduced Risk of Certain Cancers
Some research suggests that the keto diet may help prevent or treat certain types of cancer. By reducing blood sugar and insulin levels, the keto diet may lower the risk of insulin-related cancers. Additionally, cancer cells often rely on glucose for energy, and the keto diet deprives the body of sugar reserves, potentially "starving" cancer cells.
Improved Brain Function
The keto diet has been studied for its potential benefits in treating neurological disorders such as epilepsy, Alzheimer's disease, and Parkinson's disease. The production of ketones during ketosis may provide neuroprotective effects, strengthening and protecting brain and nerve cells.
Other Potential Benefits
The keto diet has also been linked to improved PCOS symptoms, reduced seizures in people with epilepsy, and a reduced risk of metabolic syndrome. Additionally, the diet may have anti-inflammatory effects and help manage acne.

Keto snacks
Snacking is an important part of the keto diet, as it helps to moderate hunger and keep you on track. Here are some ideas for keto-friendly snacks:
Savoury Snacks
- Nuts and seeds: Almonds, walnuts, pecans, pumpkin seeds, Brazil nuts, macadamia nuts, hazelnuts, peanuts, and pine nuts are all good options. Just remember to keep an eye on your net carb intake, as nuts still contain carbohydrates.
- Cheese: String cheese, Babybel, or assorted cheese slices are all good options. You can also stuff mini bell peppers with cream cheese and seasoning, or bake Parmesan cups to use as edible salad bowls.
- Meat and fish: Deli roll-ups (meat and cheese slices), smoked salmon rolls, and meatball sliders are all tasty, protein-filled options. Tuna salad with sliced tomato, or cucumber bites with tuna and mayonnaise are also good choices.
- Eggs: Hard-boiled eggs are a classic keto snack and can be made more interesting by making them into devilled eggs with cream cheese, or egg salad lettuce wraps.
- Vegetable sticks: Celery, cucumber, bell peppers, and broccoli can be eaten with guacamole, nut butter, or cream cheese.
- Olives: Enjoy these on their own, or stuff them with feta or gorgonzola cheese.
- Pickles: Fermented vegetables like pickles are a great keto snack. Try wrapping them with cream cheese and deli meat, or eat them with cheese cubes.
- Crackers: Flax crackers are a good keto option, and can be eaten with sliced cheese.
- Hummus: Regular hummus is quite high in carbs, but you can make a keto-friendly version using cauliflower instead of chickpeas. Eat it with celery sticks, carrots, or cucumbers, or use it as a spread in roll-ups.
- Mushrooms: Stuff button mushrooms with herbed cream cheese or ground sausage, or turn portobello mushrooms into mini pizzas.
- Collard greens: Use collard green leaves as a wrap for your favourite sandwich fillings.
Sweet Snacks
