What is Intermittent Fasting?  

Intermittent fasting (IF)  involves alternating cycles of eating and fasting, where you only eat during a specific window of time each day or week. This isn’t about restricting what foods you can eat but rather when you eat them.  It is not just a diet trend but a lifestyle choice that’s gaining popularity for its simple yet effective approach to improving health and managing weight. 

The beauty of IF lies in its flexibility and the way it can adapt to your lifestyle, rather than demanding drastic changes to your diet. It’s based on the principle that periods of fasting can trigger significant physiological changes in the body. 

How to do Intermittent Fasting?

Starting intermittent fasting can seem challenging at first, but with a bit of planning and some simple strategies, it can easily become part of your routine. Here’s how you can get started:

Choose Your Fasting

The first step is to pick a fasting method that suits your lifestyle. If you’re new to fasting, the 16/8 method is a great place to start. It involves fasting for 16 hours, including the time you sleep, and eating during an 8-hour window. It could mean skipping breakfast and eating your first meal at noon, then finishing your last meal by 8 PM.

Here are some samples of types of fasting you can try out:

Time-Restricted Eating (16/8 or 14/10 Method)This popular method is pretty straightforward. You fast for 16 hours and eat during an 8-hour window (like skipping breakfast and eating from noon to 8 PM) or fast for 14 hours with a 10-hour eating window. It’s like extending your overnight fast a bit longer to give your body a break from constant eating.
The 5:2 Diet (Twice-a-Week Method)On this plan, you eat normally for five days of the week. Then, for the other two days, you limit yourself to just 500–600 calories. It’s a way to reduce your overall calorie intake without making you feel like you’re always on a diet.
Alternate-Day Fasting (ADF)ADF has you switching between days of normal eating and days where you either don’t eat at all or drastically reduce your calorie intake (to about 500 calories). It’s a bit more challenging but can be very effective.
Eat-Stop-EatImagine fasting for a full 24 hours, once or twice a week, say from dinner to dinner. This method requires a bit of discipline but can significantly cut down your weekly calorie intake.
The Warrior DietInspired by the eating habits of ancient warriors, this diet involves nibbling on small amounts of raw fruits and veggies during the day and then enjoying a big meal at night. It’s designed to work with your body’s natural instincts and rhythms.
One Meal A Day (OMAD)As the name suggests, OMAD takes intermittent fasting to the extreme, where you eat just one meal a day. This meal, eaten in a one-hour window, is followed by 23 hours of fasting. It’s intense but simple to follow.
Alternate-Day Modified FastingOn fasting days, you limit yourself to about 25% of your normal calorie intake. Then, on non-fasting days, you eat a regular, healthy diet. It’s a softer approach to alternate-day fasting and can be easier to stick with.
The 12-Hour FastThis is a gentle way to dip your toes into intermittent fasting. You fast for 12 hours, including the time you’re asleep, making it an easy-to-follow method that still gives your digestive system a rest.

Plan Your Meals

When planning your meals, integrating probiotic foods for weight loss into your eating window can be a game-changer. These foods, rich in beneficial bacteria, not only support digestive health but can also contribute to a healthier metabolism and weight management. 

Including items like yogurt, kefir, sauerkraut, and kombucha in your diet ensures you get a mix of whole foods—vegetables, fruits, proteins, and healthy fats. Preparing these meals ahead of time keeps you on track with your eating window and helps avoid unplanned snacking. 


During fasting periods, it’s essential to stay hydrated. Water, black coffee, and tea are all excellent choices that won’t break your fast. Staying hydrated helps manage hunger and maintains energy levels.

Listen to Your Body

It’s normal to feel a bit hungry when you first start intermittent fasting, but this should become more manageable over time. If you’re feeling excessively tired or irritable, or if fasting is negatively impacting your daily life, reconsider your fasting plan or consult with a healthcare provider.

Be Patient and Flexible

Like any lifestyle change, intermittent fasting takes time to adjust to. Be patient with yourself and flexible in your approach. If one method doesn’t seem to work for you, try another. 

The goal is to find a fasting schedule that feels sustainable and aligns with your health and wellness goals.

Best Intermittent Fasting Tips Based On Your Age                

Adapting intermittent fasting to suit your age can maximize its benefits while ensuring it fits into your lifestyle. Here’s how to approach intermittent fasting at different stages of life, keeping in mind that flexibility and listening to your body are key.

Youthful Fasting Tips (18–30 age group)

In your youth, balancing social life and health can seem like a tightrope walk. Intermittent fasting can blend seamlessly into this dynamic phase if approached with flexibility. 

Opt for a fasting plan that allows for adjustments, making room for late-night events without compromising your goals. 

Nutrient intake is paramount; ensure your meals are rich in vitamins and minerals to support your body’s growth. Also, pairing fasting with strength training can amplify its effects, boosting muscle growth and enhancing overall vitality.

Prime Fasting (30–45 age group)

Balancing personal and professional life in your prime years requires a strategy that’s both effective and sustainable. Adopting a consistent fasting schedule, such as 16:8, helps manage the day’s demands without sacrificing health. 

Meal planning becomes a crucial ally, ensuring your diet is balanced and nutritious, ready to fuel both work and family activities. Intermittent fasting can also serve as a stress management tool, promoting mindfulness and curbing stress-eating habits.

Midlife Fasting (45–60 age group)

Navigating through midlife, intermittent fasting can be a powerful tool to address weight management and muscle maintenance. Women may find alternate-day fasting helpful during menopause, while men could focus on diets that support muscle mass. 

A nutrient-dense diet, emphasizing protein, calcium, and vitamin D, becomes increasingly important. Complement this dietary approach with hydration and strength training to support your body’s changing needs.

Senior Fasting (60+ age group)

For seniors, intermittent fasting requires a gentle approach. Shorter fasting windows, such as 12:12 or 14:10, are advisable to ensure nutritional needs are met without overburdening the digestive system. 

Before beginning, a consultation with a healthcare provider is crucial, particularly for those with pre-existing conditions or on medications. A balanced diet, rich in whole foods and variety, supports overall well-being, making fasting a beneficial adjunct to a healthy lifestyle, not a sole focus.

Benefits of Intermittent Fasting               

Intermittent fasting isn’t just a dietary choice; it’s a pathway to a myriad of health benefits, transcending simple weight loss.

Weight Management

Intermittent fasting helps regulate the body’s use of fats and sugars, leading to more effective weight management. By aligning eating patterns with the body’s natural circadian rhythm, intermittent fasting can enhance metabolic processes, making weight loss and maintenance more achievable.

Improved Metabolic Health

Regular fasting intervals can improve blood sugar levels, reduce cholesterol, and lower blood pressure, contributing to overall metabolic health. It can decrease the risk of developing type 2 diabetes and cardiovascular diseases.

Enhanced Brain Function

Intermittent fasting has been shown to support brain health, potentially improving focus, memory, and cognitive function. The practice may also offer neuroprotective benefits, reducing the risk of neurological disorders.

Increased Longevity

Research suggests that intermittent fasting can extend lifespan by promoting cellular repair processes and improving gene expression related to longevity. This effect is linked to the body’s enhanced ability to resist stress and disease.

Better Digestive Health

By allowing the digestive system regular periods of rest, intermittent fasting can improve gut health and reduce inflammation. This can lead to better digestion, reduced bloating, and a decrease in symptoms of gastrointestinal disorders.


What does intermittent fasting do?

Intermittent fasting shifts your body’s energy source from glucose to fat, helping in weight management, improving metabolic health, enhancing brain function, and potentially increasing longevity. It’s not just about skipping meals; it’s about giving your body a break to optimize health.

What can I eat while intermittent fasting?

During your eating windows, focus on nutritious foods: lean proteins, whole grains, healthy fats, and plenty of fruits and vegetables. While fasting, you can have water, black coffee, and unsweetened teas to stay hydrated without breaking your fast.

Is intermittent fasting 12 or 16 hours?

Intermittent fasting can vary. The most common form involves fasting for 16 hours with an 8-hour eating window, known as the 16/8 method. However, there are many approaches, including a milder form, the 12-hour fast, which can be a great starting point for beginners.
