The ketogenic diet, or keto, is a low-carbohydrate, high-fat eating plan that has gained popularity as a weight loss strategy. The premise of keto is to deprive the body of glucose, which is obtained by eating carbohydrates, so that an alternative fuel called ketones is produced from stored fat. This metabolic state is called ketosis. While keto has been shown to be effective for weight loss, it is not suitable for everyone and should be done under proper supervision. In this article, we will explore what to eat to lose weight fast on keto, including foods to prioritise and potential side effects to be aware of.
Ketogenic Diet Characteristics
| Characteristics | Values |
|---|---|
| Carbohydrates | Less than 50 grams a day, or as low as 20 grams a day |
| Fats | 60-80% of total daily calories from fat |
| Proteins | 10-20% of total daily calories from protein |
| Calories | No intentional calorie restriction, but weight loss depends on calories in vs. calories out |
| Intermittent Fasting | May help enter ketosis faster |
| High-Protein Variation | 60% fat, 35% protein, 5% carbs |
| Health Benefits | Weight loss, increased energy, improved focus, lower risk of cardiovascular disease, improved cholesterol levels |
| Side Effects | "Keto flu," constipation, "keto breath," upset stomach, headache, fatigue |
| Considerations | May be harmful if done incorrectly or without supervision; may not be suitable for athletes or those looking to gain muscle; can be difficult to follow |

What You'll Learn
Eat high-fat foods
The keto diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. The diet typically recommends an average of 70-80% fat from total daily calories, 5-10% carbohydrates, and 10-20% protein.
When on the keto diet, you eat too few carbs to support your body's energy needs. As a result, your body turns to burning your stores of body fat to fuel your energy. This metabolic state is called "ketosis". During ketosis, your body burns fat for energy instead of glucose.
To enter ketosis faster, you can eat more high-fat foods. Some examples of high-fat foods that you can incorporate into your diet are eggs, chicken, pork, beef, lard, tallow, coconut oil, and extra virgin olive oil.
It is important to note that the keto diet may not be suitable for everyone. Consult with your doctor or a nutritionist to determine if the keto diet is right for you.

Avoid processed foods
The keto diet is a low-carb, high-fat diet that has been found to be effective for weight loss. It involves drastically reducing your carbohydrate intake and replacing it with healthy fats, which causes your body to enter a metabolic state called "ketosis" where it burns fat for fuel instead of carbohydrates.
To lose weight fast on keto, it is important to avoid processed foods as much as possible. The keto diet already restricts a wide range of food groups, so it is crucial to make healthy choices within the allowed food groups to ensure adequate nutrition and avoid adverse health effects.
Processed foods are often high in carbohydrates and low in fiber, which can hinder your weight loss goals and disrupt ketosis. Examples of processed, grain-based snack foods to avoid include chips, crackers, and gluten-free baked goods. These foods are often marketed as healthy alternatives, but they can be just as high in carbohydrates as traditional baked goods.
In addition, processed meats such as bacon, sausage, and glazed ham should be limited or avoided. While these foods are allowed on keto, they are not the healthiest choices and may increase your risk of certain types of cancer. Instead, opt for fresh meat, poultry, chicken, fish, and beef, which contain no carbohydrates and are rich in B vitamins and minerals.
Dirty keto is a version of the keto diet that includes highly processed and packaged convenience foods. It is called "dirty" because it is associated with adverse long-term health effects, such as an increased risk of disease and nutrient deficiencies. This approach may help with weight loss in the short term, but it is not recommended as it may cause you to miss out on essential nutrients.
Instead, aim for clean keto, which focuses on whole, nutrient-dense, and unprocessed foods. This version of the keto diet emphasizes food quality and provides a more diverse array of food choices to satisfy your cravings throughout the day. Clean keto is much more likely to give your body the micronutrients it needs, promoting a more wholesome and well-rounded diet.

Drink lots of water
The keto diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. It is a restrictive diet that is not suitable for everyone. One of the common side effects of the keto diet is dehydration, often referred to as the "keto flu". This is due to the diet's impact on the body's water and electrolyte levels, as well as lower insulin levels. To prevent dehydration, it is important to drink enough water and consume sufficient electrolytes.
The amount of water one should drink while on the keto diet depends on various factors, including body weight, age, health, activity levels, and climate. As a general rule of thumb, it is recommended to divide your body weight in half and drink that many ounces of water daily. For example, if someone weighs 160 pounds, they should aim for 80 ounces of water per day. However, this amount may vary depending on individual needs and factors such as activity level and climate.
It is important to note that drinking too much water can also create problems, such as diluting sodium content and electrolyte imbalances. Thirst is usually a reliable indicator of the amount of water your body needs. In addition to water intake, consuming electrolytes is crucial on the keto diet. Electrolytes allow your body to utilize the water you are consuming effectively. You can increase your electrolyte intake by eating potassium-rich foods like leafy greens, adding salt to your meals, or taking supplements.
While the keto diet can be an effective way to lose weight, it is important to prioritize proper hydration and electrolyte balance to avoid unwanted side effects like dehydration and the keto flu. By staying hydrated and listening to your body, you can maximize the benefits of the keto diet and maintain your overall health and well-being.

Exercise regularly
Exercise is an important strategy for keeping fit and healthy, whether or not you follow the keto diet. Working out delivers health benefits in addition to weight loss. Exercise impacts ketosis by making it easier for you to enter this metabolic state, in which your body burns fat for fuel instead of glucose. Anyone who starts a keto diet will be able to reach ketosis sooner through exercise, which works by depleting glycogen stores.
Exercise also reduces hunger and cravings, and sleeping more may increase your motivation to exercise the following day. Any exercise is beneficial, and you should find what works for you by trying out different options. It could be low-intensity cardio, which most people are comfortable with, or strength training and more intense workouts. Walking, hiking, cycling, and swimming are some examples of exercises that can be easily incorporated into your routine and are effective methods of training on a keto diet.
If you are trying to lose weight, a balance of cardio and weight training is the most effective method. This mix allows you to benefit from steady energy levels for endurance activities and maintain or build muscle mass through resistance training. Studies indicate that while there might be a short-term drop in performance, many people regain and even surpass their previous strength levels once fully adapted to keto.
Exercising while on keto boosts fat burn and weight loss. If you are planning your meals around your workouts, you can consume around 50 grams of carbohydrates per day, 25 grams 30-60 minutes before the workout and the remaining 25 grams as part of your post-workout recovery.

Practice intermittent fasting
The keto diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. It is a popular diet strategy where the body is fuelled with fat instead of carbohydrates. When your body burns body fat for fuel, it produces ketones, substances made in your liver, and enters a metabolic state called "ketosis".
Intermittent fasting is a popular dieting approach that can be combined with the keto diet. It is a method of dieting that focuses on when you eat rather than what you eat. It involves eating within a specific time window and fasting for the remaining time. There are several ways to do this, such as the popular 5:2 method, where five days are normal eating days and two are extremely low-calorie fast days. Other methods include 24-hour fasts or time-restricted eating, such as eating for 8 hours and fasting for 16 hours each day (16/8 method).
Combining the keto diet with intermittent fasting may help you reach ketosis faster and result in greater fat loss. This is because intermittent fasting boosts metabolism by promoting thermogenesis, or heat production, which may lead to the utilisation of stubborn fat stores. Several studies have shown that intermittent fasting can effectively and safely reduce excess body fat. For instance, in an eight-week study involving 34 resistance-trained men, those who practised the 16/8 method of intermittent fasting lost nearly 14% more body fat than those on a normal eating pattern.
However, it is important to note that combining these two practices may not be suitable for everyone. People with certain health conditions, such as diabetes or heart disease, should consult with a doctor before trying intermittent fasting on the keto diet. Some may find it too challenging or experience adverse reactions, such as overeating on non-fasting days, irritability, and fatigue. Additionally, there is a lack of rigorous research on this combined approach, and it has not been proven specifically for weight loss.
In conclusion, while intermittent fasting may help enhance the effects of the keto diet, it is not necessary to combine the two. The keto diet alone can be effective for weight loss and improving health, and simply following a healthy, well-rounded keto diet may be sufficient for most individuals.
