Ketosis is a metabolic state in which the body burns fat for energy instead of glucose. This natural metabolic state can be achieved by reducing carbohydrate intake and increasing healthy fat intake. The keto diet, which is high in fat, moderate in protein, and low in carbohydrates, is designed to induce ketosis. While ketosis offers benefits such as weight loss, fat reduction, and improved focus and energy, it may also come with side effects like keto flu, bad breath, constipation, and dehydration. To enter ketosis quickly, strategies such as intermittent fasting, exercise, and consuming low-carb foods are recommended.
What to eat to get into ketosis
| Characteristics | Values |
|---|---|
| Carbohydrates | Reduce or eliminate carbs from your diet. Aim for 20-50 grams of carbs per day. |
| Fats | Increase consumption of healthy fats like nuts, extra virgin olive oil, coconut oil, fatty fish (salmon, tuna, sardines, mackerel), and avocados. |
| Proteins | Ensure adequate protein intake, such as eggs and meat. Aim for 1 gram of protein per pound of body weight per day. |
| Calories | Consider a calorie deficit, but focus on ketosis first and then adjust calories. |
| Intermittent Fasting | Try intermittent fasting, such as eating within an 8-hour window and fasting for the remaining 16 hours. |
| Exercise | Incorporate exercise into your routine, especially at the start of a fast, to boost ketosis. |
| Supplements | Consider supplements like MCT oil, which can aid in ketone production even with lower fat intake. |
| Hydration | Stay adequately hydrated with water, herbal teas, and coconut water. |
| Electrolytes | Maintain proper electrolyte balance by consuming enough fluids and electrolytes. |
| Fruit | Limit fruit consumption to one cup per day, preferring berries due to their lower carb content. |
| Sugar-sweetened drinks | Avoid drinks with added sugars. |

What You'll Learn
Eat more healthy fats
To get into ketosis, the body needs to burn fat instead of carbohydrates for fuel. This metabolic state can be achieved by reducing carbohydrate intake and increasing healthy fat consumption.
When starting a ketogenic diet, it is important to be mindful of common mistakes that can hinder progress. One such mistake is focusing solely on reducing carbohydrates without considering other nutrients like fats and proteins. Simply cutting carbs can derail your progress if not done correctly.
To increase healthy fat intake, aim for high-quality fats such as nuts, extra virgin olive oil, coconut oil, and fatty fish like salmon, tuna, sardines, and mackerel. Eggs are also a good source of healthy monounsaturated and polyunsaturated fats (MUFAs and PUFAs), which help regulate insulin levels and improve blood cholesterol levels. Prioritize these healthy fats over unhealthy saturated fats.
Medium-chain triglyceride (MCT) oil, often incorporated into ketogenic diets, can help increase fat intake. MCT oil is easily converted into beta-hydroxybutyrate (BHB), the main ketone body. This can lead to an increase in blood ketone levels, which is a key indicator of ketosis.
By focusing on consuming more healthy fats, you can effectively increase your chances of achieving ketosis and reaping the potential benefits of this metabolic state.

Reduce carb intake
Ketosis is a metabolic state in which the body burns fat for energy instead of glucose. To get into ketosis, reducing your carbohydrate intake is crucial. Here are some detailed tips to reduce your carb intake and enter ketosis:
Identify Hidden Carb Sources
Even small amounts of carbohydrates can add up and prevent ketosis. Be mindful of hidden sources of carbs in condiments, sauces, and dressings. For example, ketchup and honey mustard dressing contain carbs that can quickly accumulate if not tracked.
Limit Fruit Intake
Fruit is naturally high in carbohydrates, so it's best to limit your fruit intake to one cup per day. Berries are a good choice within fruits as they tend to have fewer carbs.
Avoid Sugar-Sweetened Drinks
Sugar-sweetened beverages can quickly increase your carbohydrate intake. Instead, focus on staying hydrated by consuming water, herbal teas, and coconut water.
Choose High-Fat Foods
When reducing carbs, it's essential to replace those calories with healthy fats. Aim for high-quality fats like nuts, extra virgin olive oil, coconut oil, and fatty fish like salmon, tuna, sardines, and mackerel. These foods will help you stay satiated and provide essential nutrients.
Track Your Macros
Keep track of your carbohydrate, fat, and protein intake. Counting carbs becomes easier once you get into the habit of checking food labels. There are also simple ketone tests, such as strips and monitors, available for purchase to help you track your progress.
Remember, reducing carb intake is just one aspect of entering ketosis. Combining it with intermittent fasting and exercise can help you achieve ketosis faster and experience the potential benefits of this metabolic state.

Try intermittent fasting
Intermittent fasting is a popular method for achieving ketosis. Unlike other diets, it focuses on when you eat rather than what you eat. Typically, this involves eating all your meals within an eight-hour window and fasting for the remaining 16 hours of a 24-hour period. This approach can be easier to manage than restrictive diets as it allows for more flexibility in food choices.
During the fasting period, your body resets its baseline, including mTOR activity. As the fast progresses, your body starts producing ketones, similar to a keto diet. This process can lead to ketosis, a metabolic state where your body burns fat for energy instead of glucose (sugar). Ketosis can offer several benefits, including weight loss, increased energy, and the potential treatment of chronic illnesses.
However, it's important to note that intermittent fasting may not always result in therapeutic ketosis, which requires higher levels of ketones in the blood. Additionally, it may not be suitable for everyone, especially those with certain medical conditions like diabetes or those taking specific medications. Always consult with your doctor before starting intermittent fasting to ensure it is safe for you.
Combining intermittent fasting with exercise can further accelerate ketosis. A study by Brigham Young University found that participants who exercised at the start of a 36-hour fast entered ketosis on average three and a half hours earlier than when they fasted without exercising. This highlights the synergistic effects of intermittent fasting and exercise in achieving ketosis.
Intermittent fasting can be a powerful tool for achieving ketosis and its associated health benefits. By focusing on when you eat and incorporating physical activity, you can effectively increase ketone production and transition into ketosis smoothly.

Exercise more
Exercise is a great way to get your body into ketosis. When you exercise, your body's carb reserves deplete quickly, and your body then starts to metabolize fat for energy. This metabolic shift is what we are aiming for.
The type of exercise you do can have varying effects on glucose and ketone levels. High-intensity workouts, such as HIIT, can quickly drain your glycogen stores, accelerating your shift into ketosis. Studies have shown that untrained people performing moderate-to-high-intensity exercise could deplete liver glycogen stores in just 118 minutes. Even long walks, light yoga, and other simple activities can help deplete glycogen stores and get you into ketosis.
If you are combining exercise with intermittent fasting, it is important to exercise intensely at the start of your fast. A study by Brigham Young University found that when 20 healthy adults exercised at the beginning of a 36-hour fast, they entered ketosis on average three and a half hours earlier than when they did not exercise.
Remember, it is important to consult a physician and/or nutritionist before making significant lifestyle changes, especially regarding intermittent fasting and ketosis, as well as exercise for ketosis.

Consume MCT oil
Consuming MCT oil is a great way to get into ketosis faster. MCT stands for medium-chain triglycerides, which are a type of dietary supplement that can induce ketosis without the need for a traditional ketogenic diet or prolonged fasting. MCT oil can be found in coconut oil, palm oil, and some dairy products, but these sources do not contain 100% pure MCTs. Instead, they contain a low percentage of C8, which is the most optimal form of MCT.
To optimise the effects of high-quality MCT oil, it should be extracted and consumed as a highly-concentrated, standalone product. The recommended starting dose is 5 grams of octanoic acid (C8) or a combination of C8 and decanoic or capric acid (C10), progressively increased to 15-20 grams of C8. It is best to start with a low dose to avoid any adverse effects such as abdominal discomfort, diarrhoea, nausea, and upset stomach, which have been observed in some individuals consuming MCTs.
MCTs are easily converted into ketones through a process called ketogenesis, which occurs in the liver. Ketones are a direct source of energy for the brain and can pass through the blood-brain barrier. MCT oil can help increase ketone production and provide an immediate source of energy, although it is important to note that MCTs do not contain ketones themselves.
When consumed as part of a ketogenic diet, MCT oil may help individuals reach ketosis even when they eat less fat and more protein and carbohydrates than typically recommended. This is because MCTs are a healthy source of fat and are less likely to be stored as body fat. Additionally, MCT oil can aid in weight loss by increasing the production of hormones that promote satiety and reduce overeating.
Overall, consuming MCT oil is a strategic way to enhance ketone production and achieve ketosis faster, making it a valuable tool for those following a ketogenic diet.
