The ketogenic diet, or keto, is a low-carb, high-fat diet that has gained popularity as a weight-loss method. The diet involves drastically reducing carbohydrate intake, which puts your body into a metabolic state called ketosis, where it burns fat for energy instead of carbohydrates. This can lead to significant weight loss and provide numerous health benefits. However, starting keto can be challenging as it requires a radical departure from the standard high-carb diet. Before beginning, it is important to consult with a doctor or nutritionist to ensure it is right for you and to be aware of potential side effects like the `keto flu, which can cause fatigue and other flu-like symptoms.

What You'll Learn
Consult a doctor before starting
Before starting any new diet, it is important to consult a doctor or a qualified healthcare professional. This is especially true for the ketogenic diet, which involves drastically changing your daily diet and can have side effects.
The keto diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. However, it is not suitable for everyone, and there are some serious risks associated with the diet. For example, the keto diet is high in saturated fat, which has been linked to an increased risk of heart disease. The diet can also be difficult to stick to because of the stringent food restrictions, and it may not be sustainable for some people's lifestyles and preferences.
It is important to be aware of the potential side effects of the keto diet, such as the "keto flu," which can cause extreme lethargy, mental fog, constipation, or diarrhea. The keto diet can also affect your gut health, as it requires cutting out nutrient-dense and fiber-rich foods like legumes, whole grains, starchy vegetables, and fruits. There is also a risk of dehydration, as the diet eliminates glycogen, which holds water, from the bloodstream. This can lead to a loss of electrolytes, potentially stressing the kidneys and making underlying conditions worse.
Additionally, the keto diet may not be appropriate for people with existing liver or kidney conditions. With so much fat to metabolize, the diet could make any existing liver problems worse. The kidneys help metabolize protein, and the high protein intake of the keto diet may overload them.
Therefore, it is crucial to consult a doctor before starting the keto diet to ensure that it is safe and appropriate for your individual needs and health goals. A doctor can help you understand the potential risks and benefits of the diet and advise you on how to safely and effectively implement the diet into your lifestyle.

Understand ketosis and ketoacidosis
Ketosis is a metabolic state that occurs when the body uses fat instead of glucose as fuel. This metabolic state is usually achieved by following a low-carb diet, such as the ketogenic or keto diet. Ketosis is considered safe for healthy people, and it can lead to dramatic weight loss and improve most major risk factors for heart disease. However, it may not be suitable for elite athletes or those looking to add large amounts of muscle.
When the body enters ketosis, it starts burning stored fat for energy, producing substances called ketones. Ketosis can be measured by the concentration of ketones in the blood, which can be done using a blood ketone meter or urine strips. Nutritional ketosis is not a medical condition and does not require treatment. People can exit ketosis at any time by resuming a typical amount of carbohydrate consumption.
Ketoacidosis, on the other hand, is a dangerous condition that occurs when the body produces dangerously high levels of ketones. It is a serious complication of type 1 diabetes mellitus, although it can also rarely occur in people with type 2 diabetes or severe malnutrition. Ketoacidosis happens when the body thinks it is starving and starts breaking down fats stored in the liver. This results in high levels of both glucose and ketones in the blood, making it acidic. Diabetic ketoacidosis (DKA) is a life-threatening condition that requires immediate medical attention.
It is important to distinguish between ketosis and ketoacidosis, as they are two different states with very different health implications. While ketosis is generally safe, ketoacidosis can be fatal if not treated promptly. People with diabetes can reduce their risk of ketoacidosis by eating a nutritious diet and avoiding prolonged periods without food.

Plan meals and snacks
Planning meals and snacks is essential for sticking to a ketogenic diet. The keto diet is a high-fat, moderate-protein, and low-carbohydrate diet, so meal planning should focus on including plenty of healthy fats and proteins while limiting carbohydrates.
When planning meals and snacks for a ketogenic diet, it is important to include a variety of keto-friendly foods. Meals and snacks should centre around high-fat and high-protein foods such as meat, poultry, fish, eggs, and full-fat dairy. It is also important to include low-carb vegetables and healthy fats such as nuts, seeds, and oils.
Some specific keto-friendly foods that can be included in meals and snacks are:
- Pastured, organic, or conventional eggs
- Full-fat dairy like unsweetened yoghurt, butter, and cream
- Full-fat cheese like cheddar, mozzarella, brie, goat cheese, and cream cheese
- Nuts and seeds like macadamia nuts, almonds, walnuts, pumpkin seeds, peanuts, and flaxseeds
- Nut butter like no-sugar-added peanut, almond, and cashew butter
- Oils rich in healthy fats like olive oil, avocado oil, and sesame oil
- Avocados, which can be added to almost any meal or snack
It is also important to limit or avoid high-carbohydrate foods when planning keto meals and snacks. This includes bread, pasta, potatoes, starchy vegetables, and most fruit. Sugar should also be limited or avoided, as it is a form of carbohydrate.
Meal planning can be a helpful way to stick to a ketogenic diet. This may involve creating a weekly meal plan, preparing meals in advance, and stocking up on keto-friendly foods and beverages. Reading food labels and tracking macronutrients (carbohydrates, proteins, and fats) can also help ensure that meals and snacks are in line with keto recommendations.
Some keto-friendly snack ideas include:
- Pieces of meat
- Cheese
- Olives
- Boiled eggs
- Nuts
- Raw veggies
- Dark chocolate
- Sugar-free turkey jerky
- Egg and vegetable muffins

Know what to eat and avoid
The ketogenic diet, or keto for short, is a high-fat, moderate-protein, and low-carbohydrate diet. It is a metabolic state that can be caused by a low-carb diet. It is considered safe but may cause some side effects. Before starting the keto diet, it is important to consult a healthcare professional.
To get into ketosis, the body needs to burn fat instead of carbohydrates for fuel. This means that a person needs to reduce their carb consumption and increase their fat intake. The keto diet involves a dramatic shift in eating habits, so it is important to know what foods to eat and what to avoid.
Foods to Eat
- Healthy fats such as olive oil, coconut oil, palm oil, avocado oil, egg yolk, avocado, cocoa butter, and some nuts.
- Non-starchy and fibrous vegetables that are high in nutrients and low in carbohydrates, such as broccoli, spinach, asparagus, green beans, and green bell peppers.
- Full-fat dairy.
- Red meat, pork, poultry, and fish.
Foods to Avoid
- Grains, including wheat products like bread, pasta, cereal, and rice.
- Sugar, including fruit, candy, chocolate, ice cream, and processed foods.
- Alcohol, as it slows down metabolism. However, hard liquors have zero net carbs, and spiked seltzer water is generally sweetened with artificial sweeteners, which are compatible with ketosis.
- Caffeinated beverages, as these should be limited.

Be aware of side effects
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. It is a metabolic state that occurs when your body burns fat for energy instead of glucose. Ketosis is generally considered safe, but it may cause some side effects.
One of the most common side effects of the keto diet is the "keto flu". This includes symptoms such as an upset stomach, headache, fatigue, dizziness, nausea, and constipation. These symptoms are due in part to dehydration and electrolyte imbalances that happen as your body adjusts to ketosis. To lessen the chances of getting the keto flu, start the diet slowly, stay hydrated, do only light exercises, and get plenty of rest as your body gets used to your new meal plan.
Another side effect of the keto diet is "keto breath". This is caused by the production of ketones in the body, which can lead to bad breath. The keto diet can also affect your gut health. The diet requires you to cut out nutrient-dense and fiber-rich foods like legumes, whole grains, starchy vegetables, and fruits. This can negatively affect your gut bacteria and lead to constipation.
Some other potential side effects of the keto diet include decreased bone strength, high cholesterol, kidney stones, and dehydration. It is important to monitor these symptoms throughout the diet and speak to your doctor if they persist. The keto diet may also not be suitable for elite athletes or those wishing to add large amounts of muscle or weight. More research is needed to understand the long-term effects of the keto diet on the body.
