  Fasting is a practice that has been around for centuries and plays a central role in many cultures and religions. It involves abstaining from all or some foods or drinks for a set period. Benefits of fasting on the body:
  1. Blood Sugar Control:
Fasting can enhance blood sugar regulation by improving insulin sensitivity. When you fast, your body becomes more efficient at transporting glucose from the bloodstream to cells, maintaining stable blood sugar levels and reducing the risk of spikes and crashes.
  1. Inflammation Reduction:
Chronic inflammation is associated with various health conditions. Fasting has been shown to decrease inflammation markers, such as C-reactive protein. By reducing inflammation, fasting contributes to overall well-being.
  1. Heart Health Improvement:
Combining intermittent fasting with resistance training can lead to better heart health. It reduces inflammation and positively impacts cardiovascular risk factors.
  1. Brain Function Enhancement:
Fasting stimulates the production of brain-derived neurotrophic factor (BDNF). BDNF supports cognitive function, protects against neurodegenerative disorders, and promotes brain health.
  1. Weight Loss and Metabolic Benefits:
Fasting restricts calorie intake and promotes fat burning. Both intermittent fasting and time-restricted feeding have been linked to reduced risk factors for metabolic syndrome and type 2 diabetes.
  1. Growth Hormone Release:
During fasting, the body releases growth hormones. This hormone plays a crucial role in cell repair, metabolism, and muscle growth.
  1. Longevity and Cellular Repair:
Animal studies suggest that intermittent fasting may extend lifespan. It enhances cellular repair processes and reduces oxidative stress, contributing to longevity.
  1. Potential Cancer prevention:
Fasting has garnered significant interest in the context of cancer treatment. While research is ongoing, several intriguing findings suggest that fasting may impact cancer cells in various ways:     *Slowing Cancer Growth: During fasting, glucose levels in the blood decrease. Since cancer cells heavily rely on glucose for energy, this reduction makes it harder for cancers to grow. Essentially, fasting creates an environment where cancer cells struggle to access their preferred fuel1. *Cellular Adaptations: Fasting-induced changes in metabolism may affect cancer cells. For instance, cells may alter their insulin metabolism to conserve energy. This adaptation could potentially hinder cancer cell growth1. *Reduced Insulin Growth Factor (IGF-1): Studies indicate that fasting can lower IGF-1 levels, a marker associated with increased cancer risk. By doing so, fasting may enhance normal cells’ defenses and promote cellular housekeeping mechanisms2. *Immune Activation and Inflammation Reduction: Fasting activates immune cells and reduces inflammation. Both factors play crucial roles in cancer progression. By modulating these processes, fasting may contribute to cancer prevention and treatment3. *Improved Chemotherapy and Radiation Efficacy: Emerging evidence suggests that fasting can enhance the effectiveness of cancer treatments. It may improve chemotherapy and radiation therapy outcomes while minimizing side effects4.
