The ketogenic diet is a popular weight-loss strategy that involves eating a high-fat, low-carb diet to force the body to switch from burning sugar to burning fat for energy. This metabolic state is called ketosis, and it usually takes several days to achieve. The speed of weight loss depends on several factors, including your metabolism, fitness level, and how strictly you follow the diet. While it may take a week or two to start seeing results, most people experience rapid weight loss in the first few weeks, primarily due to water loss. After this initial phase, weight loss typically slows down to a steadier pace, with a safe average of around one to two pounds per week. To achieve ketosis, you must restrict your daily carbohydrate intake to 20-50 grams and focus on consuming more saturated fats like coconut oil, butter, and meat. While the keto diet can be effective for weight loss, it is not suitable for everyone and should be approached with caution as it may lead to serious health problems.

What You'll Learn
Cut out grains, candy, sugary drinks, and most fruits and vegetables
To lose weight quickly on a keto diet, it is important to understand what foods to avoid. The keto diet is a very low-carb, high-fat diet that aims to put your body in a metabolic state of ketosis, where it burns fat instead of carbs for energy. To achieve and maintain ketosis, it is crucial to limit your carbohydrate intake to 20-50 grams per day. This means cutting out or significantly reducing certain food groups from your diet.
One of the key food groups to avoid on a keto diet is grains. This includes bread, pasta, rice, tortillas, couscous, crackers, and even whole grains like quinoa. These foods are high in carbohydrates and can quickly exceed your daily carb limit. Instead, opt for keto-friendly alternatives like keto bread, pasta, and rice made from low-carb ingredients.
Another food group to eliminate is candy and sugary treats. Sweets such as candy, cakes, cookies, pastries, and chocolate bars are strictly limited on the keto diet due to their high sugar content. Sugar is a simple carbohydrate that can easily knock you out of ketosis. It is important to read labels carefully and avoid hidden sugars in sauces, condiments, and sweetened dairy products as well.
Sugary drinks are also a big no-no on the keto diet. Soft drinks, fruit juices, and sweetened beverages can contain a surprising amount of carbohydrates. Even a single can of Coca-Cola contains 39 grams of carbs, which is almost double the recommended daily carb intake for keto. Instead, stick to water, coffee, tea, or the occasional glass of dry wine.
Lastly, while it is important to eat plenty of non-starchy vegetables on keto, some fruits and vegetables should be limited or avoided. Starchy vegetables like potatoes, sweet potatoes, and corn have a high carb content and can hinder ketosis. Most fruits are also too high in sugar for keto, except for small servings of berries, lemons, and limes.
In summary, to quickly lose weight on the keto diet, it is crucial to cut out grains, candy, sugary drinks, starchy vegetables, and most fruits. This will help you maintain a low-carb intake and keep your body in the fat-burning state of ketosis, leading to effective weight loss.

Consume lots of saturated fats like coconut oil, butter, and lard
Consuming a lot of saturated fats is a key part of the keto diet. While this may seem counterintuitive, as saturated fats are often associated with an increased risk of heart disease, more recent studies have shown that there is no link between the consumption of saturated fats and an increased risk of cardiovascular disease or type 2 diabetes. In fact, saturated fats may even have some health benefits, such as reducing levels of lipoprotein-a, which is a substance that correlates with heart disease risk, and raising levels of HDL, or "good cholesterol".
On the keto diet, it is recommended that you consume healthy saturated fats such as coconut oil, butter, and lard. Coconut oil, for example, is a source of MCT oil, which has been linked to weight loss, improved neurological health, and healthy blood sugar levels. These saturated fats are perfect for cooking due to their high smoke point and heat stability.
However, it is important to note that not all sources of saturated fat are considered equal. While animal products are abundant in saturated fats, it is recommended that you limit your consumption of fatty meats such as beef, lamb, and pork, as these are high in saturated fat and can increase your risk of heart disease. Instead, opt for leaner meats such as skinless chicken and turkey.
In addition to saturated fats, the keto diet also includes other types of healthy fats such as monounsaturated and polyunsaturated fats. Monounsaturated fats, such as those found in olive oil and avocado oil, are known for their heart-healthy benefits and ability to aid in weight loss. Polyunsaturated fats, such as those found in nuts and seeds, are important for maintaining a healthy balance of omega-3 and omega-6 fatty acids, which are essential for cognitive function and heart health.
While the keto diet may be a successful strategy for weight loss, it is important to consult with a doctor or registered dietitian before starting any new diet, as it may have serious risks for certain individuals.

Eat protein-rich foods like beef, bacon, and pork
Protein is allowed on the keto diet, but it's important to choose the right kind. The best sources of protein for ketosis are those that contain a lot of saturated fat, such as beef, bacon, and pork. These foods can be eaten in moderate amounts as part of a keto diet and will help you stay in ketosis.
The commonly recommended ratio for a keto diet is 70–80% fat, 5–10% carbohydrates, and 10–20% protein. This means that, while you can eat protein-rich foods, you should still be eating more fat than protein.
It's important to note that not all meats are created equal when it comes to keto. Lean meats like chicken and turkey are allowed on the keto diet, but they don't contain the same high levels of saturated fat as red meats like beef, bacon, and pork. This means that, while you can still eat lean meats, they should be eaten in moderation as they may impact your ability to stay in ketosis.
When choosing beef, bacon, or pork products, it's important to look for high-quality, grass-fed, or organic options where possible. Processed meats should be avoided, as they often contain added carbohydrates and other unhealthy ingredients.
In addition to meat, there are other sources of protein that can be included in a keto diet. These include fish, such as cod, salmon, and tuna, as well as eggs and some dairy products. However, it's important to be mindful of your dairy intake, as it can sometimes impact weight loss.
By including these protein-rich foods in your diet, you can ensure you're getting enough of this important macronutrient while still adhering to the keto diet and reaping the weight loss benefits it offers.

Exercise regularly
Exercise is an important component of any weight loss journey, and it is no different when it comes to the keto diet. Combining your keto diet with regular exercise can help you achieve a faster rate of weight loss. Here are some tips and guidelines to incorporate exercise into your keto weight loss plan:
Choose the Right Type of Exercise
Not all exercises are created equal when it comes to weight loss. For optimal results, it is essential to incorporate a combination of cardiovascular exercise and strength training into your routine.
- Cardiovascular exercise: Opt for activities such as walking, jogging, swimming, cycling, or interval training. These exercises elevate your heart rate and promote fat burning. Aim for at least 30 minutes of cardiovascular exercise most days of the week.
- Strength training: Strength training or resistance exercises are crucial for building and preserving muscle mass. Since muscle is metabolically active tissue, having more muscle can increase your body's calorie-burning potential, even at rest. Incorporate strength training exercises such as bodyweight exercises, weightlifting, or using resistance bands 2-3 times a week.
Exercise Intensity and Frequency
The intensity and frequency of your workouts can vary depending on your fitness level and schedule. Here are some guidelines to follow:
- Start slowly: If you're new to exercise or returning after a long break, start with moderate-intensity exercises and gradually increase the intensity and duration.
- High-intensity interval training (HIIT): If you're short on time or looking for a more intense workout, consider HIIT workouts. These involve short bursts of intense activity alternated with recovery periods. HIIT can be done with bodyweight exercises or cardio activities like sprinting.
- Consistency is key: Aim for consistency in your exercise routine. Working out 3-5 times a week is a good goal, but ensure you're not over-exerting yourself. It's important to give your body adequate rest and recovery time.
Incorporate Daily Movement
In addition to structured workouts, try to incorporate more movement into your daily routine. This can include activities such as:
- Taking short walking breaks throughout the day
- Taking the stairs instead of the elevator
- Walking while running errands
- Standing or pacing during phone calls
- Using a standing desk
Monitor Your Body's Response
Pay attention to how your body responds to exercise, especially if you're new to working out or have any health concerns. Here are some things to keep in mind:
- Stay hydrated: Drink plenty of water before, during, and after your workouts to stay hydrated, as dehydration can impact your performance and recovery.
- Listen to your body: If you experience any discomfort, excessive fatigue, or joint pain, adjust your exercises or consult a fitness professional for guidance.
- Track your progress: Monitor your progress over time. This can include measuring weight loss, taking body measurements, or tracking your workouts to see how your body is adapting to the exercises.
Remember, combining a well-formulated keto diet with regular exercise can enhance your weight loss results and overall health. Consult a certified fitness professional or trainer if you need guidance in designing an exercise program that aligns with your goals and fitness level.

Be aware of potential side effects like nausea, fatigue, dizziness, and bad breath
While the keto diet can be an effective way to lose weight, it's important to be aware of potential side effects. Nausea, fatigue, dizziness, and bad breath are some of the most commonly reported issues during the initial phase of the keto diet, often referred to as the "keto flu." This period of adjustment typically lasts for a few days to a few weeks.
Nausea is a common symptom of the keto flu, which can be mitigated by increasing your intake of water and salt. This simple remedy can provide relief within 15 to 30 minutes. Additionally, consuming more fat can help alleviate nausea and other symptoms.
Fatigue is another frequent complaint during the keto flu. This is often due to the body's transition from burning sugar to burning fat for energy. To combat fatigue, ensure you're staying properly hydrated and getting adequate electrolytes like sodium, magnesium, and potassium.
Dizziness can also occur during the keto flu, and it is often related to dehydration and electrolyte imbalances. Again, increasing your water and electrolyte intake can help alleviate this symptom.
Bad breath is a distinctive side effect of the keto diet, often referred to as "keto breath." This occurs when the body reaches a state of nutritional ketosis, and the liver produces a ketone called acetone. Acetone is released through the breath, resulting in an unpleasant odour. Staying properly hydrated and maintaining good oral hygiene practices can help minimise this side effect.
While these side effects may be unpleasant, they are typically temporary and can be managed by staying hydrated, consuming adequate electrolytes, and increasing your fat intake. However, it's important to consult a healthcare professional before starting the keto diet, as it may not be suitable for everyone.
