Intermittent Fasting: The Complete Guide to Transform Your Life

Intermittent fasting is a practice that has been gaining more and more followers worldwide due to its benefits for health and well-being. In this article, we will explore everything you need to know to start and make the most of this ancient technique. From its origins to best practices, you’ll learn how fasting can transform your routine.

What is Intermittent Fasting?

Intermittent fasting is an eating pattern that alternates between periods of eating and fasting. It’s not a diet but rather a way of structuring the times you eat. During the fasting period, the body uses its energy reserves, promoting a series of metabolic benefits.

Where Does Knowledge About Intermittent Fasting Come From?

The concept of fasting dates back to ancestral practices and religions, such as Islamic Ramadan and Buddhist fasting. Modern studies, such as those conducted by Dr. Valter Longo and other scientists, have proven its positive effects, including weight loss, improved metabolic health, and increased longevity.

The Benefits of Intermittent Fasting

1. Metabolic improvement:

• Reduction in insulin levels.
• Increased insulin sensitivity.

2. Fat burning:

• During fasting, the body enters ketosis, burning stored fat for energy.

3. Reduction of inflammation:

• Fasting helps reduce markers of inflammation, promoting better overall health.

4. Cognitive benefits:

• Improved memory and brain function due to increased BDNF (brain-derived neurotrophic factor).

How to Do Intermittent Fasting Correctly

Recommended Duration for Beginners and Advanced Practitioners:

• Beginners: Start with the 12/12 method (12 hours of fasting and 12 hours of eating).
• Advanced: Progress to 16/8 (16 hours of fasting and 8 hours for eating).

How to Start and Gradually Increase Fasting Periods

1. First Time: Start by reducing snacks between meals and avoid eating before bedtime.
2. Progression: Gradually increase the fasting period by 1 or 2 hours per week until you reach 16 hours.

What to Avoid Before Fasting

• Processed foods: Cause insulin spikes and early hunger.
• Sugars and refined carbs: Reduce the effectiveness of fasting.

What Not to Consume During Fasting and Why

• Any food: Eating breaks the fasting state and nullifies the metabolic benefits.
• Caloric beverages: Such as juices and sodas, which increase insulin levels.

What to Drink During Fasting

• Water.
• Black coffee without sugar.
• Unsweetened teas.

What to Take During Fasting to Burn Belly Fat?

• Green tea: Helps with fat burning.
• Coffee: Stimulates metabolism.

How Many Hours of Fasting Before the Body Starts Burning Fat?

Fat burning typically starts after 12 hours of fasting, when insulin levels drop and the body enters ketosis.

Why Am I Not Losing Weight with Intermittent Fasting?

• Excess calorie intake: Even while fasting, overeating during eating windows can prevent weight loss.
• Quality of food: Prioritize natural and nutrient-rich foods.

How Many Hours of Fasting to Cleanse the Intestines?

The process of autophagy, which promotes cellular cleansing, begins after about 16 to 20 hours of fasting.

Foods for Before and After Fasting

• Before: Opt for foods rich in fiber and protein, like eggs and avocado.
• After: Prioritize light meals, such as salads, vegetables, and lean proteins.

Fasting in the Morning or Evening? Is It Okay to Sleep While Fasting?

• Fasting in the morning or evening depends on your routine. Sleeping while fasting can be beneficial, as the body focuses on repairing and regenerating tissues.

How to Create an Intermittent Fasting Meal Plan

• Eating windows: Organize three balanced meals during the 8-hour eating period.
• Recommended foods: Include proteins, healthy fats, vegetables, and complex carbs.

What Breaks a Fast?

• Consuming calories, even small amounts, such as coconut oil or milk in coffee.
• Artificial sweeteners, which may stimulate insulin.

Practical Tips to Incorporate Fasting into Your Daily Routine

1. Plan Ahead: Set fixed times for fasting and eating.
2. Stay Hydrated: Drink plenty of water during fasting.
3. Be Flexible: Adapt fasting to your routine and listen to your body.
