The ketogenic diet, or keto, is a high-fat, moderate-protein, and low-carbohydrate diet that has gained popularity as a weight-loss method. The diet involves drastically reducing carbohydrate intake and replacing it with fat, which puts the body into a metabolic state called ketosis, where it becomes more efficient at burning fat for energy. This diet can be challenging to start due to the significant shift in eating habits, but it has been shown to be effective for weight loss and managing certain health conditions, such as type 2 diabetes. Before starting the keto diet, it is important to consult a physician or dietitian to ensure it is safe and suitable for your individual needs and to make any necessary adjustments to your meal plan.

Understanding the diet: high-fat, moderate protein, low-carb
The ketogenic diet, or keto, is a high-fat, moderate-protein, low-carb diet. It typically involves getting about 70% of your daily calories from fats, 20% from proteins, and only 10% from carbs. This means drastically cutting down on your consumption of starches and sugars, and replacing them with meat, fish, eggs, nuts, and healthy oils.
The keto diet is designed to induce a metabolic state called ketosis, where the body uses fat instead of carbohydrates as its primary fuel source. This is achieved by limiting carb consumption to around 20 to 50 grams per day. When the body is deprived of carbohydrates, it begins to break down fat and produce ketones, which can be used for energy.
The keto diet is popular for weight loss, but it has also been used to treat specific medical conditions. It has been shown to be effective in managing type 2 diabetes, and it has been tested for cancer, epilepsy, Alzheimer's disease, and polycystic ovary syndrome. The diet can also help to improve metabolic health and boost energy levels.
It is important to note that the keto diet can be restrictive and may not be suitable for everyone. It can also cause side effects, such as changes in the water and mineral balance of the body, and it may interact with certain medications. It is always recommended to speak to a doctor or nutritionist before starting any new diet, especially if you have other dietary restrictions or health conditions.

The different types: SKD, CKD, TKD, HPKD
The ketogenic diet is a very low-carb, high-fat diet that shares similarities with Atkins and low-carb diets. It 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 becomes very efficient at burning fat for energy.
There are several types of ketogenic diets, each focusing on slight changes in the proportion of fat, protein, and carbs in your daily meals. Here are some of the most common types:
- Standard Ketogenic Diet (SKD): This is a very low-carb, moderate-protein, and high-fat diet. Typically, it contains 70% fat, 20% protein, and only 10% carbs.
- Cyclical Ketogenic Diet (CKD): This version of the keto diet involves periods of higher-carb "refeeds." For example, you might eat keto for five days, then have two high-carb days.
- Targeted Ketogenic Diet (TKD): The TKD is designed for active people and athletes who follow a keto lifestyle but need more energy. It allows you to add carbs around intense workouts or have off days with a more balanced diet.
- High-Protein Ketogenic Diet (HPKD): The HPKD is similar to the SKD but with more protein. The ratio is usually 60% fat, 35% protein, and 5% carbs. This version may be easier for some people to follow as it allows for more protein and less fat.
The SKD and HPKD have been extensively studied and are the most common types. The CKD and TKD are newer variations mostly used by athletes and bodybuilders.

What to eat: healthy fats, nutrient-rich veggies, protein
The ketogenic diet, or keto for short, is a high-fat, moderate-protein, and very low-carbohydrate diet. It is a highly restrictive diet that is not suitable for everyone. Before starting the keto diet, it is important to consult a doctor or a nutritionist, especially if you have other dietary restrictions or health conditions.
Healthy Fats
The keto diet is a high-fat diet, and healthy fats are an essential part of it. Healthy fats include avocados, olives, olive oil, coconut oil, nuts, and seeds. Dairy products like heavy cream, full-fat cheese, and full-fat yoghurt are also good sources of fat.
Nutrient-Rich Veggies
Non-starchy vegetables like leafy greens, broccoli, peppers, zucchini, and jicama are nutrient-rich and low in carbs, making them ideal for the keto diet. It is important to note that the keto diet can lead to nutrient deficiencies as it restricts fruits and vegetables that are high in fiber and B vitamins.
Protein
Moderate amounts of protein are recommended in the keto diet. Seafood, meat, poultry, and eggs are good sources of protein. Meat and poultry contain no carbs and are rich in B vitamins and minerals, which may help preserve muscle mass during a low-carb diet. Eggs, especially whole eggs, are also a staple in keto diets as they trigger hormones that increase feelings of fullness.

What to drink: unsweetened tea/coffee, low-carb alcohol
The ketogenic diet, or keto, is a low-carb, high-fat diet that has gained popularity as a weight-loss method. It involves drastically reducing carbohydrate intake and replacing it with fat, putting your body into a metabolic state called ketosis, where it burns stored fats for energy.
When it comes to drinks, it's important to note that many beverages contain high levels of carbohydrates, which can be detrimental to ketosis. Here are some keto-friendly options for drinks besides water:
Tea and Coffee
Unsweetened tea and coffee are excellent choices for the ketogenic diet. Both drinks contain negligible calories and carbohydrates. When adding milk or cream, choose unsweetened varieties of almond, coconut, or other nut milks, as regular milk is high in carbs. You can also add zero-calorie sweeteners, sugar-free flavouring syrups, or heavy cream to increase your fat intake without increasing carbs.
Alcohol
While the ketogenic diet doesn't ban alcohol, it's important to choose low-carb options. Spirits like gin, rum, vodka, whiskey, and tequila have zero grams of carbs per 1-ounce serving. Wine is also surprisingly low-carb, with a 5-ounce serving of red or white wine containing around 3.8 grams of carbs. When mixing drinks, use soda water, plain water, or unsweetened sparkling water instead of fruit juice or sugary sodas.
It's important to note that the keto diet may reduce your tolerance for alcohol, so it's best to drink in moderation. Additionally, while diet sodas are technically keto-friendly, they may contain artificial sweeteners that can have negative effects on your gut health and strengthen sugar cravings. Instead, opt for natural zero-calorie sweeteners like stevia.

Potential side effects: keto flu, digestive issues, high cholesterol, mineral imbalance
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. However, it also has some potential side effects, including keto flu, digestive issues, high cholesterol, and mineral imbalance.
Keto flu is a condition that can occur when starting a ketogenic diet. It is characterized by symptoms such as fatigue, exhaustion, and general malaise. These symptoms are not necessarily unique to the ketogenic diet, and similar symptoms can occur when cutting back on processed foods or following an anti-inflammatory diet. The symptoms of keto flu are usually temporary and resolve within a few days as your body adjusts to the new diet. Staying hydrated, eating more frequent meals, and increasing your intake of colorful vegetables can help alleviate the symptoms of keto flu.
Digestive issues are another potential side effect of the ketogenic diet. The high-fat content of the diet can lead to changes in the digestive tract, causing gastrointestinal problems such as diarrhea and constipation. Increasing your fiber intake, consuming probiotic and prebiotic-rich foods, and reducing your intake of sugar substitutes can help alleviate digestive issues caused by the ketogenic diet. In some cases, these problems can be short-term as the body adjusts to the new diet, but they can also persist in the long term.
The ketogenic diet has been associated with an increase in total cholesterol and low-density lipoprotein (LDL) cholesterol levels. This is due to the high saturated fatty acid content of the diet. Studies have shown that patients on the ketogenic diet for an average of 12.3 months experienced a significant increase in their LDL cholesterol levels. However, when patients abstained from the ketogenic diet, their LDL cholesterol levels decreased. The long-term implications of the ketogenic diet on cholesterol levels are not entirely understood, and it is not recommended by most professional medical societies as a healthy dietary regimen for weight loss.
Mineral imbalance is another potential side effect of the ketogenic diet. When carb intake is extremely low, levels of electrolytes, especially sodium, can drop. This can disrupt the balance of other electrolytes in the body, such as magnesium and potassium. Supplementing with electrolytes and increasing the intake of mineral-rich foods can help prevent or alleviate the symptoms of mineral imbalance. Adding extra salt to your meals or consuming bone broth can also help replenish sodium levels.
