What is Intermittent Fasting?
Intermittent Fasting is a way of eating that involves alternating periods of Fasting and eating. During Fasting, you consume little or no food; during eating, you consume an average or slightly more calories than usual. The goal of IF is to put your body in a state of ketosis, which burns stored fat for energy instead of glucose.
Types of Intermittent Fasting
There are several types of IF, each with its own rules and guidelines. Some of the most popular methods include:
- 16/8 Method: The 16/8 approach is a 16-hour fast followed by an 8-hour interval for eating. One of the simplest IF strategies to implement is this one, which calls for skipping breakfast and having your first meal at midday.
- 5:2 Diet: On the 5:2 diet, you consume 500–600 less calories on the other two days of the week than you do the other five. This method can be challenging, requiring you to restrict your calories on non-consecutive days.
- Alternate-Day Fasting: Alternate-day fasting involves fasting every other day and eating normally on non-fasting days. This method can be challenging as it consists in going without food for an entire day.
- Eat-Stop-Eat: Eat-stop-eat entails a 24-hour fast once or twice every week. This procedure can be difficult because it requires a full day of fasting.
Benefits of Intermittent Fasting
Intermittent Fasting is a popular eating pattern that involves alternating periods of Fasting and eating. Here are some benefits of intermittent Fasting:

- Weight Loss: Intermittent Fasting can help you lose weight by reducing caloric intake and boosting your metabolism.
- Improved Insulin Sensitivity: Intermittent Fasting can improve your body’s response to insulin, lowering your risk of developing type 2 diabetes.
- Increased Energy: Fasting can increase the production of adrenaline and other hormones, boosting your energy levels.
- Reduced Inflammation: Intermittent Fasting can reduce inflammation in your body, improving your overall health and reducing your risk of developing chronic diseases.
- Improved Brain Function: Fasting can increase the production of a brain-derived neurotrophic factor (BDNF) protein, improving brain function and protecting against neurodegenerative diseases.
- Longevity: Some studies suggest intermittent Fasting can increase lifespan by promoting cellular repair processes and reducing oxidative stress.
How to Get Started with Intermittent Fasting?
If you’re interested in trying IF, here are some tips to help you get started:
- Choose an IF Method That Suits Your Lifestyle: There are many different types of IF, so choose one that suits your lifestyle and schedule. Consider your work schedule, social obligations, and exercise routine.
- Start Slowly: If you’re new to IF, gradually increase the length of your fasting periods. For example, start with a 12-hour fast and progressively work up to 16 or 18 hours.
- Stay Hydrated: Drink plenty of water during Fasting to stay hydrated and prevent hunger. You can also drink herbal tea or black coffee, but avoid sweetened drinks or anything that contains calories.
- Plan Your Meals: Plan your meals ahead of time to ensure that you’re eating a healthy and balanced diet. Put an emphasis on full, nutritious foods like fruits, vegetables, lean protein, and healthy fats.
- Listen to Your Body: Pay attention to how your body responds to IF and adjust accordingly. If you feel lightheaded, dizzy, or sleepy, break your fast and eat something. IF should never feel uncomfortable or restricted.
