Looking to lose weight without complicated meal planning or spending hours at the gym? Combining the keto diet with intermittent fasting may be the solution you need. In this blog post, we’ll explore how combining these two approaches can help you shed unwanted pounds and improve your metabolic health. With the fat-burning benefits of the keto diet and the calorie deficit of intermittent fasting, this approach can help you achieve your weight loss goals with ease.
First let’s understand how the body works in using energy, what it burns first, and why?
When we eat food, the body breaks it down into its component nutrients, including carbohydrates, fats, and proteins. These nutrients are then converted into a form of energy called ATP (adenosine triphosphate), which the body can use to power its functions.
When it comes to using energy, the body prioritizes different fuel sources depending on the availability of nutrients and energy demands.
- Carbohydrates: The body’s preferred energy source is glucose, which comes from the breakdown of carbohydrates. When glucose is available, the body will use it as its primary energy source and store any excess as glycogen in the liver and muscles for later use.
- Fats: When glucose is not available, the body will start to break down stored fat into fatty acids and use them for energy instead. This is known as lipolysis. The liver can also convert fatty acids into ketones, which can be used as an alternative fuel source when glucose is scarce.
- Protein: In times of extreme energy shortage, the body may break down muscle tissue and convert it into glucose through a process called gluconeogenesis.
Overall, the body is designed to be adaptable and can switch between fuel sources depending on its needs. On a keto diet, by limiting carbohydrates, the body is forced to use fat as its primary fuel source, which can lead to weight loss and other health benefits.
What is a keto diet?
- A keto diet is a high-fat, low-carbohydrate diet that aims to put the body in a metabolic state called ketosis
- In ketosis, the body burns fat for fuel instead of carbohydrates
- The macronutrient breakdown of a keto diet is approximately 70-75% fat, 20-25% protein, and 5-10% carbohydrates
- By limiting carbohydrates, the body is forced to use fat as its primary energy source, which can lead to weight loss
- The production of ketones during ketosis has been linked to improved insulin sensitivity, reduced inflammation, and improved brain function
- A keto diet may not be appropriate for everyone.
What are the foods allowed on a keto diet? – what to eat
On a keto diet, the focus is on consuming high-fat, low-carbohydrate foods. Some foods that are typically included in a keto diet include:
- Fats and oils: butter, coconut oil, olive oil, avocado oil, and other healthy oils.
- Protein: meat, poultry, fish, eggs, and some low-carbohydrate protein powders.
- Non-starchy vegetables: leafy greens, broccoli, cauliflower, Brussels sprouts, zucchini, and other low-carbohydrate vegetables.
- Nuts and seeds: almonds, macadamia nuts, walnuts, chia seeds, and flaxseeds.
- Dairy: cheese, cream, and some low-carbohydrate dairy alternatives like almond or coconut milk.
- Low-carbohydrate fruits: berries, such as strawberries, raspberries, and blackberries, are typically allowed in moderation.
- Vegetables: leafy greens, cruciferous vegetables, zucchini, avocado, tomatoes, mushrooms, asparagus, green beans, cauliflower, and celery.
What are the foods not allowed on a keto diet? – what not to eat
On a keto diet, the focus is on consuming high-fat, low-carbohydrate foods while limiting or avoiding foods high in carbohydrates. Some foods that are typically avoided on a keto diet include:
- Grains: including wheat, rice, oats, and corn.
- Sugar: including table sugar, honey, maple syrup, and other sweeteners.
- High-carbohydrate fruits: including bananas, grapes, mangos, and other high-sugar fruits.

- Processed and junk foods: including candy, cookies, chips, and other foods high in refined carbohydrates.
- Sugary drinks: including soda, juice, and other high-sugar beverages.
How do you make keto the most effective for maximum weight loss?
Here are some tips for making a keto diet as effective as possible for maximum weight loss:
- Stay within your macronutrient range: It’s important to calculate your daily macronutrient needs (fat, protein, and carbohydrates) based on your goals, and then track your food intake to ensure you’re staying within that range. This will help ensure you’re in a state of ketosis and burning fat for fuel.
- Prioritize nutrient-dense, low-carbohydrate foods: Focus on consuming high-quality, nutrient-dense foods such as non-starchy vegetables, healthy fats, and high-quality protein sources. Avoid processed and junk foods even if they are low in carbohydrates.
- Practice intermittent fasting: Intermittent fasting involves cycling between periods of eating and fasting. This can help enhance the benefits of a keto diet and accelerate weight loss.
- Stay hydrated: Drinking plenty of water and staying hydrated can help with weight loss by reducing hunger and increasing satiety.
- Exercise regularly: Incorporating regular exercise into your routine can help enhance weight loss and improve overall health. Exercise can also help you maintain muscle mass while losing fat.
- Get enough sleep: Getting adequate sleep is important for weight loss and overall health. Lack of sleep can disrupt hormones that regulate hunger and satiety, leading to overeating.
How much can you lose a week with just keto alone?
the amount of weight lost on a keto diet varies based on several factors.
- Factors affecting weight loss on a keto diet include age, gender, starting weight, activity level, and adherence to the diet.
- Rapid weight loss is common in the first few weeks of a keto diet due to water weight and glycogen reduction.
- After the initial period, weight loss may slow to around 1-2 pounds per week or less.
- Losing weight too quickly can be unhealthy and challenging to maintain.
- Results may vary from person to person.
- It’s important to focus on overall health and well-being rather than just weight loss.
- The keto diet can provide other benefits besides weight loss, such as improved insulin sensitivity and reduced inflammation.
What are the recommended portion sizes on a keto diet?
Here are some general guidelines for portion sizes on a keto diet:
- Protein: Aim to consume 3-6 ounces (85-170 grams) of protein per meal, depending on your individual needs and goals. This can be in the form of meat, poultry, fish, eggs, or tofu.
- Fats: Fats should make up the majority of your calorie intake on a keto diet, but it’s still important to be mindful of portion sizes to avoid consuming excess calories. Aim to consume 1-2 tablespoons of oil, butter, or other fats per meal.
- Vegetables: Non-starchy vegetables are an important source of fiber and nutrients on a keto diet. Aim to fill half of your plate with vegetables and choose a variety of colors and textures.
- Fruits: While fruits are generally limited on a keto diet due to their carbohydrate content, small portions of low-carbohydrate fruits like berries can be consumed in moderation. Aim to keep fruit portions to around 1/4 cup.
- Nuts and seeds: Nuts and seeds are a great source of healthy fats and protein on a keto diet. However, it’s important to be mindful of portion sizes to avoid consuming too many calories. Aim to keep nut portions to around 1 ounce (28 grams) per serving.

What happens when you use keto and intermediate fasting?
When used together, a keto diet and intermittent fasting can be a powerful combination for weight loss and other health benefits. Intermittent fasting involves cycling between periods of eating and fasting and can help enhance the benefits of a keto diet by promoting ketosis and accelerating weight loss.
Here are some ways to use keto and intermittent fasting together:
|1st -2nd week||16/8 method||This involves fasting for 16 hours each day and eating during an 8-hour window. Many people choose to have their first meal at noon and their last meal before 8 pm. During the eating window, it’s important to consume nutrient-dense, low-carbohydrate foods that are high in healthy fats and protein.|
|3rd – 4th week||24-hour fast||This involves fasting for 24 hours once or twice a week. During the fast, it’s important to stay hydrated and avoid consuming any calories.|
|Optional for max weight loss||Alternate-day fasting||This involves alternating between days of eating normally and days of fasting. On fasting days, it’s important to stay hydrated and avoid consuming any calories.|
|alternative method||Fat fasting||This involves consuming very high-fat foods while limiting protein and carbohydrates to induce ketosis more quickly. This is often used as a way to jumpstart ketosis before transitioning to a standard keto diet.|
It’s important to note that fasting can be challenging for some people and may not be appropriate for everyone, especially those with certain medical conditions. It’s important to talk to a healthcare professional before starting any new diet or fasting regimen.
who can not use keto and intermediate fasting?
Intermittent fasting is not recommended for everyone. Here are some groups of people who should avoid intermittent fasting or consult with a healthcare professional before starting:
- Pregnant or breastfeeding women
- Children and teenagers
- Individuals with a history of eating disorders
- Individuals with a history of low blood sugar or diabetes
- Individuals taking certain medications that require food intake at regular intervals
- Individuals with a history of gastrointestinal issues
- Individuals with a history of heart disease or other serious medical conditions
If you fall into one of these categories or have any concerns about starting intermittent fasting, it’s important to consult with a healthcare professional before beginning.
What are some tricks for making intermittent fasting easier?
Intermittent fasting can be challenging, especially when you’re first starting out. Here are some tips and tricks to help you stay on track:
- Start slow: If you’re new to intermittent fasting, start with shorter fasting periods and gradually increase the duration over time.
- Stay hydrated: Drink plenty of water throughout the day to stay hydrated and help reduce hunger.
- Use calorie-free beverages: To help you get through fasting periods, consume calorie-free beverages like black coffee, tea, or sparkling water.

- Seek support: Join a support group or seek guidance from a healthcare professional or registered dietitian to help you stay on track and achieve your goals.
How do you keep the weight off after reaching your goal?
Maintaining weight loss can be challenging, but there are some strategies you can use to help keep the weight off after reaching your desired weight. Here are some tips:
- Continue to follow a healthy, nutrient-dense diet: After reaching your desired weight, it’s important to continue to follow a healthy, balanced diet. Focus on consuming plenty of vegetables, high-quality protein sources, and healthy fats.
- Monitor your food intake: Even after reaching your desired weight, it’s important to continue to monitor your food intake to ensure you’re not consuming too many calories. This can help you maintain your weight loss and prevent weight gain.
- Stay active: Regular physical activity is important for maintaining weight loss and overall health. Aim to incorporate at least 150 minutes of moderate-intensity exercise per week.
- Practice mindful eating: Paying attention to your body’s hunger and fullness cues can help you avoid overeating and maintain your weight loss. Avoid eating in front of screens and take time to savor and enjoy your food.
- Get enough sleep: Getting adequate sleep is important for weight maintenance and overall health. Aim to get 7-9 hours of sleep per night.
- Manage stress: Stress can contribute to weight gain and difficulty maintaining weight loss. Practice stress-management techniques such as meditation, deep breathing, or yoga.
Can you reintroduce all food groups after reaching your goal weight?
Once you have reached your desired weight, you may be able to slowly reintroduce some foods that were previously restricted on the keto diet. However, it’s important to do so in moderation and pay attention to how your body responds.
For example, you may choose to add some whole grains, fruits, and starchy vegetables back into your diet in limited amounts while still prioritizing nutrient-dense, low-carbohydrate foods. It’s important to monitor your weight and pay attention to how your body feels after eating these foods to determine if they are right for you.
It’s important to note that some people may find that they feel better and have better weight maintenance by continuing to follow a low-carbohydrate, high-fat diet even after reaching their desired weight. Ultimately, the best diet for weight maintenance is one that you can sustain long-term and that supports your overall health and well-being. It’s important to talk to a healthcare professional before making any significant changes to your diet.
Will eating previously restricted foods cause you to regain weight?
If you go back to eating the foods that were restricted on the keto diet in excess, you may experience weight gain. This is because high-carbohydrate foods can lead to an increase in insulin levels, which can promote fat storage in the body.
However, it’s important to note that weight gain is not solely dependent on the types of foods you eat, but also on the amount of food you consume and your overall energy balance. Consuming excess calories from any food source can lead to weight gain.
Additionally, weight maintenance is not just about the foods you eat, but also about your overall lifestyle habits. Regular physical activity, getting enough sleep, managing stress, and staying hydrated are all important factors that can impact weight maintenance.
If you choose to reintroduce high-carbohydrate foods into your diet after reaching your desired weight, it’s important to do so in moderation and pay attention to how your body responds. It may be helpful to track your food intake and monitor your weight to ensure you’re maintaining your desired weight.
The keto diet and intermittent fasting can be effective weight loss strategies when used correctly and under the guidance of a healthcare professional. By reducing carbohydrates and promoting fat burning, the keto diet can help individuals achieve their weight loss goals. When combined with intermittent fasting, which can promote a calorie deficit and improve metabolic health, this approach can be even more effective. However, it’s important to remember that a sustainable approach to weight loss and management is key, and extreme or unsustainable diets should be avoided. It’s also important to listen to your body, stay hydrated, and seek guidance from a healthcare professional or registered dietitian to ensure that your diet and lifestyle changes are safe and effective.
