Fasting is a practice as ancient as human civilization itself, often rooted in cultural and spiritual traditions. In recent years, it has undergone a resurgence as a health trend, thanks to a growing body of research underscoring its numerous physiological and psychological benefits. This ancient technique, adapted into modern life as intermittent fasting, represents more than a mere dietary change—it’s a transformative lifestyle choice that has helped many achieve profound health benefits. From dramatic weight loss transformations to improved metabolic health, fasting is being embraced by people from all walks of life.
Fasting has long been touted as a transformative practice, both for body and mind. It is often surrounded by controversy but backed by ancient tradition and modern science alike.

The information for this article is largely based on a video shared by Mike Diamonds in which he discusses how fasting can heal the body.

How Fasting Can Heal the Body
1. Weight Loss and Body Composition Enhancement
Fasting contributes significantly to weight loss and changes in body composition by adjusting hormonal functions that regulate metabolism. Mike Diamonds observes that fasting increases the activity of norepinephrine, a key hormone that helps mobilize fat and improve metabolic rate. This process not only aids in reducing body fat but also supports muscle maintenance and growth when combined with resistance training. As noted by Diamonds, “Fasting isn’t just about losing weight; it’s about shifting your body’s reliance on different energy sources, which can lead to substantial fat loss and muscle gain.”

2. Improvement in Insulin Sensitivity
One of the most profound impacts of fasting, as highlighted by Mike Diamonds, is the improvement in insulin sensitivity. By naturally lowering insulin levels during fasting periods, the body enhances its responsiveness to insulin when it is reintroduced. “This dynamic shift not only helps in controlling blood sugar levels but also significantly lowers the risk of type 2 diabetes,” explains Diamonds. This benefit is particularly crucial for those predisposed to metabolic syndrome and diabetes.
3. Cardiovascular Health Boost

Fasting also plays a critical role in cardiovascular health by influencing various biomarkers associated with heart disease. Mike Diamonds points out that fasting can lead to reductions in blood pressure, cholesterol levels, and inflammatory markers. “Regular fasting can remodel your heart health by optimizing blood lipid profiles and reducing inflammation, key factors in decreasing the risk of cardiovascular diseases,” states Diamonds.
4. Enhancement of Brain Function
Beyond its physical health benefits, fasting significantly affects cognitive functions and brain health. Mike Diamonds remarks on the increase in production of brain-derived neurotrophic factor (BDNF) during fasting, which supports neuron health and cognitive functions. “BDNF acts like fertilizer for the brain, enhancing memory, learning, and the brain’s ability to adapt to new challenges,” says Diamonds. This is particularly beneficial for aging adults and those looking to preserve cognitive function.
5. Digestive System Reset
Fasting offers a respite for the digestive system, allowing it to repair and reset. “When you fast, the digestive tract gets the chance to ‘clean house,’ reducing bloating and inflammation and improving overall gastrointestinal health,” explains Mike Diamonds. This break can help mitigate symptoms of chronic digestive disorders, such as IBS (Irritable Bowel Syndrome), and enhance nutrient absorption during feeding times.
Each of these benefits, discussed by Mike Diamonds, underscores fasting’s potential as a multifaceted health tool, capable of transforming not just body composition but also enhancing systemic health across various bodily systems.

How To Deal With Hunger During Intermittent Fasting
The benefits of intermittent fasting extend far beyond simple weight management. This practice has the potential to catalyze profound changes in nearly every system of the body, from the brain to the heart to the gut. By adjusting the timing of meals, fasting can enhance cognitive function, improve cardiovascular health, stabilize blood sugar levels, and increase gastrointestinal recovery periods, leading to overall health improvements. These benefits highlight fasting’s role not just as a health trend, but as a sustainable lifestyle practice with deep-rooted scientific backing.
Moreover, fasting’s ability to challenge and change our relationship with food can lead to a healthier lifestyle and a more mindful approach to eating. While fasting might not be suitable for everyone—such as those with certain health conditions or nutritional needs—it offers an accessible, powerful tool for many looking to improve their health. As with any dietary change, it’s essential to approach fasting thoughtfully and consider personal health circumstances and, if necessary, consult healthcare professionals to tailor the fasting approach to individual health needs and goals. This holistic view of fasting, grounded in personal success stories and scientific research, paints a compelling picture of its potential as a powerful tool in the arsenal of health and wellness strategies.
