Medical experts have confirmed that intermittent fasting is an effective dietary approach for enhancing health and promoting weight loss-provided it is practiced mindfully and under proper medical supervision. They highlighted its role in eliminating what they referred to as “harmful white fat” and converting it into energy-rich “brown fat.”

The specialists warned against following this dietary method randomly, emphasizing the need for a gradual start. Maintaining high food quality and avoiding excessive intake of fast food and sweets are also essential to safely gain its health benefits.

Speaking to Emarat Al Youm, doctors explained that intermittent fasting typically involves refraining from eating for periods ranging from 12 to 18 hours or longer. They stressed the importance of consulting a healthcare provider before starting-especially for high-risk groups such as pregnant and breastfeeding women, insulin-dependent diabetics, the elderly with chronic illnesses, individuals with eating disorders, and children and teens during growth stages.

Doctors noted that intermittent fasting could be a viable option for some patients with type 2 diabetes who follow specific dietary plans and are not fully insulin-dependent. However, professional medical oversight is crucial to prevent hypoglycemia and ensure safe treatment adjustment.

Multiple scientific studies have validated the effectiveness of intermittent fasting, showing its ability to reduce weight, lower blood sugar and cholesterol levels, decrease the risk of heart disease, and enhance brain and memory function.

Despite these benefits, doctors cautioned that some side effects may occur, including headaches, dizziness, sleep disturbances, constipation, and acid reflux. A balanced diet and adequate water intake are essential to support overall health and maximize results.

Dr. Abd Al Baset Al-Eisawy, a consultant in nephrology and internal medicine, elaborated that intermittent fasting helps shift the body’s energy source from glucose to stored fat-a process known as “metabolic switching.” It also allows the digestive system to rest, enhances immune function by stimulating “cellular autophagy,” and improves mitochondrial performance-the energy engines of the body-by transforming harmful white fat into beneficial brown fat.
