The ketogenic diet, or keto, is a low-carb, high-fat diet. It can be effective for weight loss and certain health conditions, as demonstrated in many studies.
On a keto diet, you cut back significantly on carbohydrates, which puts your body into a metabolic state called ketosis. In this state, your body becomes incredibly efficient at burning fat for energy. It also turns fat into ketones in the liver, which can supply energy for the brain.
The keto diet is a low-carb, high-fat diet. It lowers blood sugar and insulin levels and shifts the body’s metabolism away from carbs and toward fat and ketones.
There are several versions of the keto diet, including the standard ketogenic diet (SKD), cyclical ketogenic diet (CKD), targeted ketogenic diet (TKD), and high protein ketogenic diet. The SKD is the most researched and most recommended.
The keto diet is a far cry from the fad low-fat diet approaches of yesteryear. It's a restrictive diet that requires careful planning and can be challenging to stick to. However, it can be an effective way to lose weight and improve health.

What You'll Learn
What to eat on a keto diet
The ketogenic diet is a high-fat, low-carbohydrate, and moderate-protein diet. It is a very restrictive diet, and it is important to make sure you get enough fibre.
The keto diet was originally developed to treat certain types of childhood epilepsy. More recently, it has become popular among people trying to lose weight.
The keto diet involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where your body uses fat for energy instead of glucose.

What to avoid on a keto diet
A ketogenic diet is a low-carb, high-fat diet that can be effective for weight loss and certain health conditions. To achieve ketosis, a metabolic state where your body uses fat for fuel instead of carbs, it is important to avoid certain food groups that are high in carbohydrates. Here is a list of food groups that should be avoided or limited when following a keto diet:
- Grains and Starches: Wheat, rice, corn, and oats are high in carbohydrates and can impact blood sugar levels, hindering the body's ability to enter ketosis.
- Sugary Foods and Sweets: Candies, pastries, sugary drinks, and other sweet treats cause a quick rise in insulin levels, which hinders fat burning and encourages fat storage.
- Starchy Vegetables: Potatoes, yams, and corn are starchy vegetables that are high in carbohydrates and should be restricted.
- Legumes and Beans: Lentils, chickpeas, and black beans are high in carbohydrates and can interrupt ketosis and cause fluctuations in blood sugar levels.
- Processed Foods: Chips, pre-packaged snacks, and convenience meals often contain hidden sugars and starches that can impede keto progress.
- Alcoholic Beverages: Alcoholic drinks, especially when mixed with sugary syrups or sodas, can result in a significant intake of carbohydrates and delay ketosis.
- High-Carb Sauces and Condiments: Ketchup, BBQ sauce, and sweet dressings often contain sugars and starches that can quickly add up and disrupt ketosis.
- Trans Fats and Hydrogenated Oils: Partially hydrogenated oils, which often contain trans fats, can have negative effects on heart health and contribute to inflammation.
- Low-Fat and Diet Products: Low-fat and diet items often include added sugars and artificial sweeteners, increasing your carbohydrate intake and impeding keto progress.
It is important to note that some foods, such as fruits, can be consumed in moderation even though they are high in carbohydrates. Additionally, there are substitute options available for some food groups, such as cauliflower rice instead of traditional rice, that can help you stay on track with your keto diet while still enjoying a variety of foods.

How to create your own keto meal plan
The keto diet is a high-fat, low-carbohydrate diet that can be challenging to follow, especially for vegetarians and vegans. However, with some planning and preparation, it is possible to create a keto meal plan that suits your unique preferences and lifestyle. Here are some tips to help you get started:
Determine Your Macronutrient Ratios
On a keto diet plan, your meals typically contain less than 20 grams of net carbs (total carbs minus fibre) per day. They also provide enough protein to meet your needs and help you feel satisfied. To achieve this, focus on eating more meats, fish, eggs, and plant and animal fats while limiting your intake of starchy foods and sugary treats.
Build Your Keto Plate
At each meal, include a generous portion of protein, such as meat, fish, eggs, or tofu; one or more servings of keto vegetables like leafy greens and cauliflower; and healthy fats like olive oil or butter to add flavour and meet your energy needs.
Plan Your Meals in Advance
Meal planning is essential on the keto diet to ensure you adhere to the correct macronutrient ratios, meet your fibre goals, and prevent hunger. There are many keto-friendly foods to choose from, including meat, poultry, fish, eggs, cheese, nuts, seeds, and non-starchy vegetables.
Prepare and Stock Up
Cooking double portions for dinner and refrigerating or freezing the leftovers for another day can save time and effort. Stock up on keto-friendly foods and read product labels carefully to check the ingredients list and carb content.
Stay Hydrated and Supplement with Electrolytes
Drinking plenty of fluids and supplementing with electrolytes can help minimize symptoms of the "keto flu," which some people experience when first starting the diet.
Consider Intermittent Fasting
If you're not hungry in the morning, consider skipping breakfast and trying intermittent fasting. This can help simplify your keto journey and maximize weight loss.
Seek Professional Guidance
Finally, consider working with a doctor or dietitian to ensure your keto meal plan meets all your nutritional needs and doesn't cause any deficiencies.
By following these tips and tailoring your meals to your preferences, you can create a keto meal plan that is both enjoyable and effective in helping you achieve your health and weight loss goals.

Intermittent fasting and keto meal planning
The ketogenic diet is a low-carb, high-fat diet that can be effective for weight loss and certain health conditions. When following a ketogenic diet, your body enters a metabolic state called ketosis, where it uses fat for fuel instead of carbohydrates. This can lead to significant reductions in blood sugar and insulin levels, which can have various health benefits.
Intermittent fasting is a dieting pattern where you choose to miss certain meals. It can be an effective way to lose weight and improve health, especially when combined with a ketogenic diet. When paired together, intermittent fasting and keto can help you lose weight faster and burn more body fat.
- Meal timing: Most keto and intermittent fasting meal plans involve eating two meals a day within an eight-hour window and fasting for the remaining 16 hours. This is often referred to as a 16:8 intermittent fasting plan. You can also explore other intermittent fasting protocols like the 5:2 diet, 24-hour protocol/OMAD (one meal a day), or alternate-day fasting.
- Food choices: During your eating window, make sure to include a generous serving of protein (meat, poultry, fish, eggs, dairy, or plant-based protein) and plenty of low-carb vegetables. Healthy fats like avocado, nuts, and olive oil are also essential on a keto diet.
- Beverages: Stick to carb-free or low-carb beverages such as water, black coffee or tea, bone broth, and unsweetened nut milk. Avoid sugary drinks, fruit juices, and alcoholic beverages.
- Sample keto meals: Here is a sample keto meal plan for one week:
- Breakfast: Veggie and egg muffins with tomatoes
- Lunch: Chicken salad with olive oil, feta cheese, olives, and a side salad
- Dinner: Salmon with asparagus cooked in butter
- Breakfast: Egg, tomato, basil, and spinach omelet
- Lunch: Almond milk, peanut butter, spinach, cocoa powder, and stevia milkshake with a side of strawberries
- Dinner: Cheese-shell tacos with salsa
- Breakfast: Nut milk chia pudding topped with coconut and blackberries
- Lunch: Avocado shrimp salad
- Dinner: Pork chops with Parmesan cheese, broccoli, and salad
- Snacks: If you get hungry between meals, opt for keto-approved snacks like nuts, hard-boiled eggs, keto-friendly snack bars, full-fat Greek yogurt with nut butter and cocoa powder, or celery with guacamole.
- Supplements: While not required, some supplements can be beneficial on a keto diet, such as MCT oil, minerals, caffeine, exogenous ketones, and creatine.
- Side effects: The keto diet may cause some initial side effects like keto flu, digestion issues, and decreased energy levels. To minimize these, ease into the diet gradually, stay hydrated, and consider taking mineral supplements.
- Long-term risks: While keto can be beneficial in the short term, there may be some negative effects from following the diet long-term, including low protein in the blood, extra fat in the liver, and micronutrient deficiencies. Consult your doctor before starting and maintaining a keto diet to ensure it aligns with your health goals and needs.
