What is intermittent fasting?
Intermittent fasting is a dietary approach where you cycle between periods of fasting and eating. Basically, you alternate between periods of time where you don’t eat anything and periods where you consume your meals. There are several different ways to practice intermittent fasting, but the most popular methods involve fasting for 16-24 hours and then eating during a designated feeding window of 8-10 hours. Some people also do alternate day fasting, where they eat normally one day and then fast the next. The idea behind intermittent fasting is that it can help you lose weight, improve metabolic health, and potentially even increase longevity.
Types of Intermittent Fasting
- 16/8 Method: This is also known as the Leangains method and involves fasting for 16 hours and then eating during an 8-hour window.
- 5:2 Method: This involves eating normally for 5 days of the week and then consuming only 500-600 calories on the other 2 days.
- Alternate Day Fasting: As the name suggests, this method involves fasting every other day. On fasting days, you can either consume no calories or limit your calorie intake to 500-600.
- 24-Hour Fasting: This involves fasting for a full 24 hours, once or twice a week.
- Warrior Diet: This method involves eating one large meal at night and fasting during the day.
- OMAD (One Meal a Day): This involves eating one large meal per day and fasting for the remaining 23 hours.
There are many other variations of intermittent fasting, and it’s important to choose one that works for your lifestyle and health goals.

How to Achieve Intermittent Fasting?
- Choose a fasting method: There are many different approaches to intermittent fasting, so it’s important to choose one that works for you. You could try the 16/8 method (fast for 16 hours and eat during an 8-hour window), the 5:2 method (eat normally for 5 days and then limit calorie intake to 500-600 for 2 non-consecutive days), or the alternate day fasting method.
- Plan your meals: Once you’ve chosen a fasting method, it’s important to plan your meals accordingly. During your feeding window, you should aim to eat healthy, balanced meals that are rich in nutrients. It’s also important to stay hydrated and drink plenty of water throughout the day.
- Start gradually: If you’re new to intermittent fasting, it’s a good idea to start gradually. Begin with shorter fasting periods and gradually work your way up to longer periods. This will help your body adjust to the new eating pattern and reduce the risk of side effects like headaches or low energy levels.
- Stay consistent: To see the benefits of intermittent fasting, it’s important to stay consistent. Try to stick to your chosen fasting method and feeding window as much as possible. This will help your body get into a rhythm and improve your chances of success.
