Keto And Intermittent Fasting: A Weight Loss Power Couple?

The ketogenic (keto) diet and intermittent fasting are two of the most popular health trends today. The keto diet is a high-fat, very low-carb way of eating, which forces your body to rely on fats instead of glucose for energy. Intermittent fasting, on the other hand, is an eating pattern that involves cycling between periods of fasting and normal eating. Both methods are used to lose weight and control certain health conditions. When combined, keto and intermittent fasting may help the body reach ketosis faster and result in greater fat loss. However, there is a lack of rigorous research on the combined approach, and it has not been proven to work for weight loss.

Intermittent fasting and keto: a safe combination?

The ketogenic (keto) diet and intermittent fasting are two of the most popular health trends today. Both methods are used to lose weight and control certain health conditions. While both have solid research backing up their purported benefits, it is still unclear whether combining the two is a good idea.

Intermittent fasting is an eating method that alternates between periods of fasting and normal eating. There are several types of intermittent fasting routines, including the 5:2 method, the Warrior Diet, and alternate-day fasting. The most popular type is the 16/8 method, which involves eating during an eight-hour window and then fasting for 16 hours. Intermittent fasting is primarily used as a weight loss technique, but it has also been shown to reduce inflammation and improve brain function and blood sugar control.

The keto diet is a high-fat, very low-carb way of eating. Carbohydrates are typically reduced to 20-50 grams per day, which forces the body to rely on fats instead of glucose for energy. This metabolic process is called ketosis, where the body breaks down fats to form substances called ketones, which serve as an alternative fuel source. The keto diet has been used to treat epilepsy and also shows promise for other neurological disorders, such as improving mental symptoms in people with Alzheimer's disease.

Potential Benefits of Combining Both

Combining intermittent fasting with the keto diet may offer the following benefits:

• May help the body reach ketosis faster than with the keto diet alone.
• May lead to more fat loss as intermittent fasting boosts metabolism and can help the body utilize stubborn fat stores.
• May result in greater weight loss than with the keto diet alone.

Who Should Try This Combination?

Combining the keto diet with intermittent fasting is likely safe for most people. However, pregnant or breastfeeding women and those with a history of disordered eating should avoid intermittent fasting. People with certain health conditions, such as diabetes or heart disease, should consult a doctor before trying this combination. It is important to note that this combination may not work for everyone, and some may find it too difficult or experience adverse reactions.

Potential Risks of Combining Both

There is a lack of rigorous research on the combined approach of keto and intermittent fasting, and it has not been proven to work for weight loss. It is extremely restrictive, and it may be challenging to stick to the low-carb count and confined eating window. Additionally, there is a risk of nutritional deficiencies, and it may not be suitable for those with a history of disordered eating.

While combining keto and intermittent fasting may lead to greater weight loss, it is not necessary to combine both methods. Some people may find that one practice works better for them than the combination. As with any major lifestyle change, it is advisable to speak to a healthcare provider before starting this or any other diet.

The benefits of intermittent fasting

Intermittent fasting is a popular health trend that involves eating during a specific time window and fasting for the remainder of the day. It is often combined with the keto diet, which is a high-fat, very low-carb diet. While there is limited research on the combined approach of keto and intermittent fasting, they each have individual benefits.

Weight Loss

Intermittent fasting is primarily used as a weight loss technique. It has been shown to reduce hunger and promote feelings of fullness, which can aid in weight loss. Studies have also shown that it can lead to substantial weight loss in short periods, as well as changes in body composition.

Health Benefits

In addition to weight loss, intermittent fasting has been linked to several health benefits. It can help reduce inflammation and improve brain function and blood sugar control. It may also help manage inflammation-related health conditions like arthritis and asthma.

Intermittent fasting can also have a positive impact on cognitive health. Reducing oxidative stress can support memory and learning functionality, which is beneficial for brain aging.

Flexibility

There are several different methods of intermittent fasting, such as the 5:2 method, the Warrior Diet, and the popular 16/8 method, which gives individuals the flexibility to choose a method that suits their lifestyle and preferences.

Ease of Maintenance

Intermittent fasting may be easier to maintain than other diets as it focuses on when to eat rather than restricting specific foods. This can make it less challenging to stick to, as individuals are not constantly counting calories and feeling deprived every day.

Safety

Intermittent fasting is likely safe for most people, but it is important to consult with a healthcare professional before starting any new diet, especially for those with certain health conditions, a history of disordered eating, or those who are pregnant or breastfeeding.

How to start with keto and intermittent fasting

Combining the ketogenic diet with intermittent fasting may help you reach ketosis faster and increase weight loss. However, it is important to note that this method may not be suitable for everyone. Before starting, it is advisable to consult a healthcare professional.

If you decide to combine keto and intermittent fasting, it is generally recommended to start with keto first and then introduce intermittent fasting. Here are some steps to help you get started:

• Start with keto: The ketogenic diet is a high-fat, very-low-carb diet. Typically, you will be consuming between 20 to 50 grams of net carbs (carbs minus fibre) each day, while prioritising healthy fats such as avocados, olive oil, grass-fed beef, and occasional bacon.
• Understand ketosis: The goal of the keto diet is to transition your body from burning glucose (carbs) for fuel to relying on fat for energy. This state is called ketosis or being keto-adapted. During ketosis, your body breaks down fats to form substances called ketones, which serve as an alternative fuel source.
• Choose your intermittent fasting method: There are several popular methods of intermittent fasting. The most common one is the 16/8 method, which involves fasting for 16 hours and eating during an 8-hour window. Other methods include the 5:2 method (normal eating for five days and extremely low-calorie fasting for two days), 24-hour fasting, and time-restricted eating.
• Start slowly with intermittent fasting: You can begin with a simple 10-hour eating window followed by a 14-hour fast. This might just mean having your breakfast a little later or avoiding late-night snacks. As you adjust, you can gradually push your breakfast back and extend your fasting period.
• Plan your meals: When following the keto diet, it is essential to plan your meals. Opt for low-carb or zero-carb options for breakfast, lunch, dinner, and snacks. Remove high-carb foods from your pantry and fridge, such as chips, crackers, and sugary drinks or juices.
• Monitor your progress and well-being: Combining keto and intermittent fasting can be challenging, and it is important to listen to your body. Make sure to monitor your progress and how you feel. If you experience discomfort or adverse effects, consult your healthcare provider.

Remember, it is not necessary to combine keto and intermittent fasting to achieve ketosis and weight loss. A well-rounded keto diet and intermittent fasting as a standalone strategy can also be effective. It is essential to tailor your approach based on your unique needs and preferences.

The right way to do intermittent fasting on keto

If you are considering combining the keto diet with intermittent fasting, it is important to know the right way to do it.

Firstly, it is not advisable to start both diets at the same time. The transition from using glucose as fuel to using ketones is a huge shock to your system, and intermittent fasting is also a significant change. Therefore, it is recommended to start with keto, and then after a couple of weeks or months, you can consider adding intermittent fasting.

When you are ready to add intermittent fasting, it is important to choose the correct timing. A 12- to 16-hour fast is recommended. For many people, not eating for 12 hours a day is a natural habit, such as overnight from 7 pm to 7 am.

To start, you can try delaying breakfast by an hour and then slowly extending the time to get your body accustomed to going longer stretches without eating. Once you have adjusted to your new eating pattern, you can reintroduce breakfast earlier in the day and extend your overnight fasting time.

It is recommended to stay on the keto-intermittent fasting diet for no more than six months and then transition to a more standard low-carb diet or another recommended healthy eating plan.

Important Considerations

While the keto diet and intermittent fasting can be combined safely for most people, it is not suitable for everyone. Pregnant or breastfeeding women and those with a history of disordered eating should avoid intermittent fasting. People with certain health conditions, such as diabetes or heart disease, should consult with a doctor before trying this combination.

Additionally, it is important to note that this combination may not work for everyone. Some people may find it too difficult or experience adverse reactions, such as overeating on non-fasting days, irritability, and fatigue.

Intermittent fasting is not necessary to reach ketosis, and a well-rounded keto diet is sufficient for improving health by cutting down on carbs. It is recommended to consult with a healthcare provider before making any major lifestyle changes.

Intermittent fasting and keto: long-term risks

Intermittent fasting and keto are two of the most popular health trends. While both have solid research backing their purported benefits, there is a lack of rigorous research on the effects of combining the two. Here are some potential long-term risks of combining the two diets:

• Micronutrient losses or electrolyte deficiencies: This can occur when not enough nutrients are consumed during the eating window.
• Vitamin deficiencies: Not consuming enough fat can lead to vitamin deficiencies, as dietary fat helps with the absorption of vitamins A, D, E, and K.
• Loose skin: Losing a lot of weight very quickly can lead to loose skin, although this doesn't happen to everyone.
• Hypoglycemia: For people with type 2 diabetes, combining intermittent fasting with keto and blood glucose medications can cause blood glucose levels to drop too low.
• Ketoacidosis: People with type 1 diabetes may be at risk of ketoacidosis, which is characterized by dangerously high ketone levels.
• Not suitable for everyone: Pregnant or breastfeeding women and those with a history of disordered eating should avoid intermittent fasting. People with certain health conditions, such as diabetes or heart disease, should consult a doctor before trying this combination.

While combining keto and intermittent fasting may lead to greater weight loss and have other potential benefits, it is important to be aware of the potential long-term risks and consult a healthcare professional before starting any new diet.
