What exactly is fasting?
Fasting as a whole, isn’t a new concept. Throughout human history, fasting has been a common practice.
Fasting is taking a break from eating for a set period of time. It's like giving your body a mini-vacation from digesting food. Consequently, humans have developed the ability to endure long periods without food.
People fast for various reasons, including health benefits, religious practices (Islam, Christianity, Judaism, and Buddhism), or personal goals.
When you fast, your body gets a chance to focus on other important tasks, like repairing cells and balancing hormones.
Many who try fasting report feeling more energised, mentally sharp, and even experiencing a natural "glow" in their appearance.
What is intermittent fasting?
Intermittent fasting isn't just another diet trend—it's a powerful approach to eating that can unleash your body's natural fat-burning potential. At its core, intermittent fasting is about when you eat, not what you eat.
It involves cycling between periods of eating and fasting, typically with a daily eating window of eight to 12 hours followed by a fasting period of 12 to 16 hours.
This simple shift in timing can power up your metabolism, boost energy levels, and potentially lead to significant weight loss. While those two methods are the most common, there are several ways to do intermittent fasting.
The best part? Intermittent fasting is flexible and can be adapted to fit your lifestyle.
Whether you choose the popular 16/8 method, where you fast for 16 hours and eat within an eight-hour window, or opt for alternate-day fasting—the key is finding what works for you. As you embark on this journey, remember that your body is incredibly adaptable.
By giving it regular breaks from constant digestion, you're allowing it to focus on cellular repair and fat burning. While it may take some adjustment at first, many people report feeling more focused, energised, and in control of their eating habits once they settle into their fasting routine.
So, let’s get into the intermittent fasting benefits that can elevate your health.

What are the health benefits of intermittent fasting?
Intermittent fasting isn’t just another fad diet. It’s a lifestyle change that’s been backed by science and embraced by people all over the world.
While there are a plethora of reasons why people choose to fast, one common reason is the health benefits.
Let’s get into what IF can potentially do for your health.
Fat burning mode
When you're not constantly eating, your body's like, "Whoa, no new fuel coming in? Time to burn some fat!" It's your chance to break through that stubborn weight plateau.
Brain power boost
Fasting can make your brain feel sharper. It's like clearing out the mental fog and helping you focus better. You might just feel strong enough to tackle that tough homework or nail that presentation.
According to the National Library of Medicine, intermittent fasting can help improve mild cognitive impairment.
Other studies also claim increasing the production of a protein called BDNF. This could potentially help protect against conditions like Alzheimer's and depression.
Cellular cleanup
Your body starts a process called autophagy, which is like a deep clean for your cells. Out with the old, in with the new! It's how you keep your body running smoothly.
Hormone hustle
Fasting can help balance out your hormones. It might boost growth hormone (hello, muscles!) and improve insulin sensitivity. It's all about optimizing your body's systems.
Inflammation cooldown
Fasting can help reduce inflammation in your body. Less inflammation means you might recover faster from workouts and generally feel better.
Gut reset
Giving your digestive system a break can be like hitting the reset button. It might help with bloating and other tummy troubles.
Potential longevity boost
Some studies suggest fasting might help you live longer. It's like giving your body a tune-up to keep it running that little bit extra.
Note: Be mindful that everyone's body reacts differently. The key is to listen to your body and find what works for you. If you're feeling weak or unwell, that's your cue to eat something.
The main types of intermittent fasting diet
Whether you're looking to shake up your eating routine, boost your health, or just curious about what all the fuss is about—you're in the right place.
These fasting methods are like different flavours of ice cream—there's something for everyone—and you might need to try a few to find your favourite.
From easier beginner methods to more intense approaches, we've got the scoop on all the popular intermittent fasting styles that can help you elevate yourself and unleash your potential.
The 16/8 method: This is like skipping breakfast. You eat for eight hours a day and fast for 16. Maybe you eat from noon to 8pm and then chill without food until noon the next day.
The 5:2 diet: Eat normally for five days a week, then cut down to about 500 to 600 calories for the other two days. It's like giving your body a mini-vacation from all that food processing.
Eat stop eat diet: Once or twice a week, you don't eat for a full 24 hours. It's like telling your body, "Hey, let's take a day off from eating and see what happens!"
The warrior diet: You eat small amounts of raw fruits and veggies during the day, then feast like a queen at night. It's all about unleashing your inner warrior.
Alternate day fasting: One day you eat normally, the next day you eat very little. It's like a rollercoaster for your metabolism.
Spontaneous meal skipping: This is the laid-back approach. Just skip meals when you're not hungry or too busy. It's like telling your body, "We'll eat when we feel like it."
FYI: The key is to find what works for you. Intermittent fasting can help you conquer your fitness goals and elevate yourself to new heights.
But always listen to your body and talk to a healthcare professional before making big changes to your eating habits.
