The Methods & Benefits of Intermittent Fasting

Not just what we eat but when we eat

In today’s ever-evolving landscape of diet and nutrition, two approaches have emerged as frontrunners in the quest for weight management and improved metabolism. These are intermittent fasting and time-restricted eating, and they share a common emphasis on not just what we eat but when we eat it.

UNDERSTANDING INTERMITTENT FASTING AND TIME-RESTRICTED EATING

Intermittent fasting doesn’t fit the conventional definition of a diet; rather, it’s an eating pattern that alternates between periods of fasting and eating. Timerestricted eating, a subcategory of intermittent fasting, narrows daily eating to a specific window of time. Both strategies draw inspiration from our body’s natural rhythms.

EXPLORING DIFFERENT METHODS

Imagine fasting for 16 hours each day and then enjoying your meals within an 8-hour window. This is the essence of the 16/8 Method, one of the most popular forms of intermittent fasting.

Time-restricted eating can be viewed as a simpler approach, as intermittent fasting can involve extended fasting periods, time-restricted eating offers a more accessible and sustainable path. This approach simplifies meal timing without significant calorie restrictions.

BENEFITS OF INTERMITTENT FASTING

Intermittent fasting brings with it a slew of potential benefits. Published author and nephrologist, Dr. Jason Fung, speaks frequently to the benefits of intermittent fasting and has dedicated much of his career to the topic. In a video he recently published, he provides advantages to fasting when it comes to specifically to weight loss1, emphasizing the flexibility and accessibility. There are, however, far more benefits to consider. It can improve insulin sensitivity, crucial for blood sugar regulation and lowering the risk of type 2 diabetes2. Beyond this, it sparks a process known as autophagy, where the body cleanses itself of damaged cells and fosters the growth of new ones. This cellular rejuvenation may contribute to a longer, healthier life.3

The length of fasting will vary depending on the person. For those easing into the concept, the 12/12 or 14/10 method may be an ideal starting point. This method entails fasting for 12 or 14 hours daily and eating within the remaining hours. Stepping up, the 18/6 method suggests fasting for 18 hours daily, with a 6-hour eating window. For those looking for a more rigorous challenge, the 20/4 method narrows the eating window to just 4 hours within a 20-hour fasting period.

Stephanie Dubois from CBC news published in a research article that Dr. Fung expressed the most common fasting strategy is 16 hrs of fasting while eating within an eight-hour period.

“There’s pluses and minuses of all [of those] strategies. So it’s not like one is right and one is wrong. It’s finding what really works for you,” he said.

BENEFITS OF TIME-RESTRICTED EATING

Time-restricted eating mirrors many of the benefits of intermittent fasting, such as effective weight management, simplified meal planning that encourages healthier food choices, improved digestion, and potential enhancements in circadian rhythms that lead to better sleep patterns. Like its counterpart, timerestricted eating also may offer metabolic advantages.

IS INTERMITTENT FASTING OR TIMERESTRICTED EATING RIGHT FOR YOU?

While both intermittent fasting and time-restricted eating have their merits, determining which approach aligns best with your preferences, lifestyle, and health goals is crucial. It’s wise to consult with a healthcare professional or registered dietitian before embarking on any fasting regimen, especially if you have underlying medical conditions or dietary concerns.

Intermittent fasting and time-restricted eating are innovative strategies that synchronize our eating habits with our body’s natural rhythms. Whether you gravitate toward the flexibility of intermittent fasting or the simplicity of time-restricted eating, the key lies in prioritizing balanced nutrition, hydration, and overall well-being.

During an episode of CBC’s The Dose, Dr. Fung was interviewed by guest host Dr. Peter Lin and shared “The idea is not deprivation or to go into excess, but to balance the feeding and the fasting because both are very essential for us.”

Personalization is key, ensuring that the chosen approach suits your unique needs and preferences. As with any lifestyle change, consistency and moderation are the cornerstones of long-term success on your journey to health and wellness.
