What Is Intermittent Fasting?

Intermittent fasting (IF) has become one of the most popular approaches to weight loss and wellness in recent years. Instead of focusing on what you eat, intermittent fasting is about when you eat. It involves cycling between periods of eating and fasting to support weight loss, improve metabolic health, and simplify daily routines.

Some of the most common fasting methods include:

  • 16:8 (Fasting for 16 hours and eating within an 8-hour window)
  • 5:2 (Eating normally for five days a week and reducing calorie intake on the other two days)
  • 24-hour fasts (Fasting for a full day once or twice per week)

But is intermittent fasting a legitimate, science-supported approach to health or just another passing trend?

The Science Behind Intermittent Fasting

A growing body of research suggests that intermittent fasting is more than just a fad. In fact, when done correctly, it may offer a range of evidence-based health benefits.

Weight Loss and Fat Reduction

By limiting the time available for eating, intermittent fasting often leads to a natural reduction in calorie intake. During fasting periods, insulin levels drop, which encourages the body to burn stored fat for energy. Several studies have shown that intermittent fasting can be just as effective as traditional calorie-restricted diets for weight loss.

Improved Blood Sugar Control

Intermittent fasting has been shown to help improve insulin sensitivity and regulate blood sugar levels. This can be particularly beneficial for people at risk of developing type 2 diabetes. However, people with existing diabetes should speak to a healthcare professional before starting any fasting regimen.

Heart and Brain Health

Emerging research also links intermittent fasting with reduced inflammation, lower blood pressure, and improved cholesterol levels. Some studies suggest it may even support brain health by enhancing cognitive function and potentially reducing the risk of neurological diseases like Alzheimer’s.

Cellular Repair and Longevity

One of the lesser-known benefits of intermittent fasting is its effect on autophagy, a natural process where cells remove damaged components and regenerate. This process may help protect against disease and contribute to healthy ageing.

Is Intermittent Fasting Right for Everyone?

While intermittent fasting can offer real benefits, it’s not suitable for everyone. Certain people should approach fasting with caution or avoid it altogether. These include:

  • Individuals with diabetes or blood sugar disorders
  • Those with a history of eating disorders
  • People who are pregnant or breastfeeding
  • Anyone with underlying medical conditions or who is underweight 

It’s always best to speak to a pharmacist, GP, or healthcare professional before making significant changes to your eating habits.

Tips for Getting Started with Intermittent Fasting

Thinking of giving intermittent fasting a try? Here are a few tips to get you started safely: 

  • Ease into it: Start with a 12:12 schedule (12 hours fasting, 12 hours eating) and work your way up
  • Stay hydrated: Drink plenty of water, herbal teas, or black coffee during fasting hours
  • Eat nutritious foods: Focus on balanced meals rich in protein, fibre, and healthy fats during eating windows
  • Listen to your body: If you feel faint, irritable, or unwell, stop and seek professional advice

Final Thoughts: Fad or Fact?

Intermittent fasting is backed by science, but it’s not a one-size-fits-all solution. For many people, it can be a helpful tool for managing weight, improving metabolic health, and simplifying dietary habits. But as with any lifestyle change, it works best when it’s safe, sustainable, and personalised to your needs.
