Intermittent Fasting Beneficial or Harmful? Here Is What Science Actually Says

Intermittent fasting is a dietary method where people eat food during specific windows of the day or week and abstain from eating during the remaining hours.

A common method of intermittent fasting is the 16:8 method. It involves fasting for 16 hours and eating during an 8 hour window. Other methods include restricting calorie intake on specific days.

People typically adopt this routine to manage their weight or get metabolic health benefits

Intermittent Fasting Vs. Ramadan Fasting

Experts also note that intermittent fasting is different from Ramadan fasting.

Intermittent fasting is practiced for health and weight management. Fasting during Ramadan is a religious act. It is focused on worship, self discipline, spiritual reflection and empathy for others. It involves abstinence from both food and drink from dawn to sunset.

What the Research Shows

Intermittent fasting is often marketed as a solution to improve metabolism, lower blood sugar and cholestrol, regulate blood pressure, trigger cell repair and reduce the risk of diseases like cancer.

However, nutritionists and clinical researchers state that the evidence supporting these claims remains limited.

According to Krista Vardy, a nutrition researcher at the University of Illinois at Chicago, intermittent fasting is not a unique biological formula. Clinical research shows that while the method successfully aids weight loss. However it does not perform significantly better than standard daily calorie restriction or other traditional dieting strategies.

Experts emphasize that the weight loss benefits are driven by eating fewer calories overall rather than any special fasting mechanism.
