Intermittent fasting (IF) is one of the most popular health trends today, and for good reason. It promises weight loss, improved body composition, and potential health benefits.
Simply put, it’s a form of calorie restriction that alternates between periods of eating and fasting. Unlike other diets, it doesn’t require eliminating specific food groups or counting calories. Here’s everything you need to know about intermittent fasting to lead a healthier life.
What is Intermittent Fasting?
Intermittent fasting is an eating pattern that restricts your eating periods. You eat less while letting your body rest in alternate states of fasting. It is said to improve the functioning of hormones, increase metabolism, and reduce inflammation.
There are different types of IF, and the most popular ones include:.
Types of IF
1. 16/8 Method
This is the most popular type of IF, and it involves fasting for 16 hours and eating for 8 hours. It is also known as the Leangains method. During the eating window, you can consume two or three meals.
You can skip breakfast and eat your first meal at noon and have your last meal at 8 pm.
2. 24-Hour Fast
As the name suggests, this involves not eating anything for a full day. It’s best to do this once a week or twice a month when you can rest, sleep and avoid any strenuous physical activity.
3. 5:2 Diet
This involves consuming a low amount of calories (400-500 calories) for two non-consecutive days in a week. On the other five days, you eat normally.
4. Alternate-Day Fasting
This involves alternating between eating and fasting periods. You eat normally on one day and fast for the next day. Repeat the cycle.
What Happens During Intermittent Fasting?
Intermittent fasting deprives your body of calories, forcing it to tap into the stored fat as energy. When you eat, your body breaks down carbohydrates into glucose, which it uses for immediate energy.
Any unused glucose is stored in the liver and muscles as glycogen. When you fast, your body uses up the stored glycogen as an energy source. In the absence of carbohydrates, your body starts converting fats into energy called ketones through a process called ketosis.
Ketosis reduces inflammation and oxidative stress, which is beneficial for good health.
Health Benefits of Intermittent Fasting
Here are some of the health benefits of intermittent fasting:.
1. Weight Loss:
IF can help you lose weight by reducing your calorie intake and increasing your metabolic rate. Also, it reduces insulin resistance, which means your body can burn stored fat more effectively.
2. Improves Brain Functioning:
Researches found that IF can improve cognitive function, memory and reduce inflammation that cause neurodegenerative diseases.
3. Increases Life Expectancy:
IF can increase your lifespan as it can repair cells and regenerate tissues by reducing oxidative stress and inflammation which are the two factors responsible for aging.
4. Improved Heart Health:
IF can reduce bad cholesterol levels and improve blood pressure which lowers the risk of heart diseases.
How to Start Intermittent Fasting
Here is how you can start intermittent fasting:.
1. Pick a Plan:
Choose the type of IF that suits you best. Remember to ensure that you eat nutrient-dense foods during the eating window and stay hydrated throughout the fasting and non-fasting periods.
2. Start Slow:
Don’t make sudden changes to your eating habits. Start by reducing snack time then gradually increase the fasting hours.
3. Stay Hydrated:
Drink enough water and have non-caloric drinks like coffee, tea, or apple cider vinegar drinks to maintain peak hydration levels.
Conclusion
Intermittent fasting can help you optimize your health and fitness goals, but it’s not for everyone. It’s best to speak to a dietitian or medical professional before starting IF, particularly if you are diabetic, pregnant, or have any health conditions.
If implemented correctly, it’s a safe and effective tool for improving your overall well-being.
