Types of Intermittent Fasting
Types of Intermittent Fasting

1. Types of Intermittent Fasting

1.1. 16/8 Method (LeanGains Protocol):

This method involves fasting for 16 hours and condensing all your daily eating into an 8-hour window. For instance, if you start eating at noon, you’ll stop at 8 p.m.


  • Flexible and easily integrated into daily life.
  • Can skip breakfast or dinner, based on personal preference.
  • Potential for reduced calorie intake without meticulous calorie counting.


  • Some may find it challenging to consume adequate nutrients in the restricted window.
  • Overeating during the 8-hour period can negate the benefits.

Ideal Candidates: Those new to intermittent fasting or individuals looking for a balanced method without extreme fasting periods.

1.2. 5:2 Diet (The Fast Diet):

This approach involves eating normally for five days of the week while drastically reducing calorie intake (around 500–600 calories) on the other two days.


  • Less stringent than daily fasting.
  • Potential metabolic boost from periodic calorie restriction.


  • The low-calorie days can be tough, leading to feelings of fatigue or irritability.
  • It is important to ensure that nutrient intake is balanced on low-calorie days.

Best Suited For: Individuals who prefer not to fast every day and can manage short bursts of significant calorie restriction.

1.3. Alternate-Day Fasting:

As the name suggests, this approach involves fasting every other day. There are two main versions of this method: one where no calories are consumed on fasting days, and another where about 500–600 calories are allowed during fasting days.


  • Significant calorie reduction can lead to weight loss.
  • Potential for deeper cellular repair due to longer fasting periods


  • May be hard to sustain in the long run.
  • Fasting days can be particularly challenging, especially when just starting out.

Best Suited For: Those who are already familiar with intermittent fasting and are seeking a more rigorous method, or individuals who appreciate a structured, rhythmic pattern to their diet.

1.4. The Warrior Diet:

Originating from ancient warrior societies, this diet involves eating small amounts of raw fruits and vegetables during the day and consuming one large meal in the evening. The fasting period is 24 hours.


  • Mimics the eating patterns of ancient warriors, potentially aligning with our evolutionary history.
  • Allows for a substantial evening meal, which can be socially and psychologically satisfying.


  • Limited daytime eating can be challenging for those with high energy demands throughout the day.
  • Requires careful meal planning to ensure nutritional needs are met.

Who It’s Ideal For: Those who prefer a more ‘naturalistic’ approach to eating, or people who find it easier to have one primary meal a day, often in a family or social setting.

1.5. Extended Fasts:

This involves fasting for periods longer than 48 hours, often up to 72 hours or more. It’s less common than other methods and should be approached with caution.


  • Deep cellular autophagy, where the body cleans out damaged cells and regenerates new ones.
  • Significant metabolic shifts and potential for fat loss.


  • Extended fasts can lead to nutrient deficiencies if not managed correctly.
  • Potential for severe fatigue, dizziness, or other health concerns.
  • It’s crucial to reintroduce food correctly after an extended fast to prevent refeeding syndrome.

Who Should Consider It? Individuals with specific health goals that align with extended fasting benefits. It’s critical to have medical supervision or at least consult with a healthcare professional before undertaking an extended fast.

1.6. Water Fasting:

This method involves abstaining from all food and drink except water for a specific period. It’s one of the most straightforward fasting methods in terms of rules: no consumption of anything except water.


  • Potentially deeper detoxification and cellular autophagy due to the complete absence of caloric intake.
  • Can lead to more rapid weight loss compared to other methods.


  • Can be tough, especially for beginners or those used to shorter fasts.
  • There is a risk of nutrient and electrolyte imbalances if extended for longer periods without proper preparation or follow-up.
  • Potential side effects like dizziness, fatigue, or headaches.

Best Suited For: Individuals looking for a deeper cleanse or reset, or those who have experience with other forms of fasting and wish to explore a more intense method. It is always recommended to be done under supervision or after consultation with a healthcare professional.

1.7. Dry Fasting:

One of the most extreme forms of fasting, dry fasting, involves abstaining from all food and water. There are two types: soft dry fasting (allowing things like brushing teeth or washing hands) and hard dry fasting (no contact with water at all).


  • Some claim faster fat loss since the body might break down fat to retrieve water.
  • This may lead to more profound detoxification and healing effects in a shorter period of time.


  • Significantly tougher than other fasting methods.
  • High risk of dehydration, which can lead to severe health complications.
  • It is not recommended for extended periods due to the potential for severe nutrient and electrolyte imbalances.

Best Suited For: Few individuals might opt for dry fasting, usually for religious or deep detoxification purposes. Extreme caution is required, and it should never be undertaken without thorough research and, ideally, medical supervision. Most healthcare professionals would advise against it due to the inherent risks.

2. The right type of Intermittent Fasting for you!

Choosing the right intermittent fasting method isn’t about jumping on a trend, but about aligning the practise with your individual needs, lifestyle, and health goals. Here are key criteria to consider when selecting a fasting method:

2.1. Personal Goals:

  • Weight Loss: If your primary objective is weight loss, shorter daily fasts like the 16/8 method might be beneficial due to their daily calorie restriction nature.
  • Deep Cellular Cleanse: For those interested in more profound cellular autophagy, longer fasts such as the Eat-Stop-Eat or extended fasts may be appropriate.
  • Metabolic Health: Concerns about insulin resistance or type 2 diabetes might make methods like the 5:2 diet appealing due to the periodic significant calorie reduction.

2.2. Daily Routine and Lifestyle:

  • Work Schedule: If you have long workdays, a rigid fasting schedule might be challenging. Opt for flexible methods.
  • Social Commitments: Regular social events involving food might align better with methods that allow occasional breaks, like the 5:2 diet.
  • Family Dynamics: If you have family meals, select a method that aligns with those timings or offers flexibility.

2.3. Health Status:

  • Existing Medical Conditions: Those with conditions like diabetes or hypoglycemia should consult a physician before starting any fasting regimen.
  • Medications: Some medicines require intake with food. Ensure your fasting schedule doesn’t interfere with medication timing.

2.4. Dietary Preferences and Habits:

  • Vegetarian or Vegan: If your diet is plant-based, ensure you get adequate nutrients during your eating windows, especially proteins.
  • Keto or High-Fat Diets: Those following a ketogenic diet might benefit from methods like the Warrior Diet, which supports larger meals in the evening.
  • Frequent Snacking: If you’re used to constant snacking, starting with a shorter fasting window and gradually extending it might ease the transition.

2.5. Physical Activity and Workout Routine:

  • High-Intensity Workouts: If you’re into high-intensity training, align your eating window around your workout times to fuel your body effectively.
  • Endurance Athletes: Those into long-duration activities might find it challenging to sustain energy on strict fasting methods. Flexibility is key.
  • Rest & Recovery: Longer fasting intervals might require adjustments in workout intensity or duration to ensure ample recovery.

2.6. Experience with fasting:

  • Beginners: If you’re new to fasting, starting with a more lenient method like the 12/12 or gradually moving into the 16/8 can help you acclimatise.
  • Experienced Fasteners: If you’ve successfully practised intermittent fasting and seek a deeper experience, exploring extended fasts or alternate-day fasting might be the next step.

3. Addressing Common Challenges of Intermittent Fasting:

Introducing any significant change in your dietary routine, like intermittent fasting, can bring about various challenges. Recognising and addressing these challenges is crucial to ensuring a successful and sustainable fasting journey.

3.1. Dealing with Hunger:

  • Physical vs. Psychological hunger: Distinguishing between the two can help. While physical hunger builds gradually and can be satisfied with any food, psychological hunger is sudden and often craves specific foods.
  • Drinking Water: Sometimes, our bodies confuse thirst with hunger. Drinking water can help suppress false hunger signals.
  • Balanced Macronutrients: Consuming balanced meals with adequate protein, fats, and fibre can promote satiety and reduce hunger during fasting windows.

3.2. Managing Social Events and Meals:

  • Planning Ahead: If you know you have a social event, you might adjust your eating window or take a break from fasting for that day.
  • Making Informed Choices: Even when eating out, opt for dishes that align with your nutrition goals.
  • Communicate: Letting friends and family know about your fasting routine can ensure understanding and support.

3.3. Balancing Energy, Especially During Workouts:

  • Timing Workouts: If possible, time your workouts during your eating window or right before breaking your fast to ensure energy availability.
  • Listening to Your Body: If you’re feeling particularly fatigued, consider a lighter workout or resting.
  • Nutrient Timing: Consuming a balanced meal or snack post-workout can aid recovery and energy replenishment.

3.4. Potential Nutrient Deficiency:

  • Diverse Diet: Ensure your eating windows include a variety of foods to cover all essential nutrients.
  • Supplementation: If there’s a concern about not getting specific nutrients, consider supplements after consulting with a healthcare provider.

4. Conclusion

The human body’s ability to adapt and thrive under different conditions makes intermittent fasting more than just a diet craze. After studying the several fasting approaches, one thing is clear: there’s no one-size-fits-all solution. Your goals, lifestyle, and physiology determine your ideal fasting approach, like your fingerprint. This path requires an open mind and a willingness to change based on body feedback. Intermittent fasting requires respect, patience, and persistence for weight loss, cellular repair, greater attention, and other advantages.
