It has gained popularity as a diet that limits food to an 8-hour window and is widely promoted for weight loss. Although it has attracted global attention, research suggests that it may not be without risk.

A new study published in Diabetes and Metabolic syndrome: Clinical Research and Review has added to the fasting to high heart risks.

Drawing the data of more than 19,000 adults in the US National Health and Nutrition Examination Survey, researchers examined long -term health results based on the daily dining period.

He found that the participants who ate for less than 8 hours a day were a specific 12–14-hour eaten within the window, compared to those, there was a risk of heart mortality rate (death caused by heart and blood vessel diseases).

Although the link with overall mortality was weak and incompatible, elevated heart mortality risk remained in many demographic and lifestyle subgroups and 14 separate sensitivity analysis (advanced testing). The authors insisted that these conclusions do not prove the reason.

“Our study provides the first evidence that individuals who follow the window less than 8 hours were more likely to die of heart disease, which follow a typical after a 12–14-hour eating window. Although our observation results are subject to residual confusion, people should be very skeptical about adopting such a small-eating window.

Dr. Anoop Mishra, Fortis-C-Dock Center of Diabetes, President of Metabolic Disease and Endocrinology, underlined both research strength and boundaries.

To profit, he stated that many random controlled tests and meta-analisis show intermittent fasting, which can reduce weight, improve insulin sensitivity, reduce blood pressure, improve better lipid profiles and even some anti-inflammatory effects. It can also help some individuals manage blood sugar levels without strict calorie count, and it fits well with cultural or religious fasting practices, while relatively simple to follow.

On a possible decline, Dr. Mishra warned of nutrient deficiencies, excessive appetite, irritability, headache and poor adherence over time. In people with diabetes, the lymphatic fasting may trigger hypoglycemia (low blood sugar). In older adults or people with chronic disease, prolonged fasting may be infamous or muscle loss.

An inner fasting, they emphasized, not a size-fit-all solution. Its gains and risk depend on population, specific fasting protocols and the context in which it is applied.

Commenting on data, Dr. Mishra said, “All reasons with mortality were incompatible and not strong. Entral fasting provides metabolic benefits in some groups, but can harm others, especially without supervision.” He said that more long -term random tests are required to clarify its safety and guide to clarify the recommendations.
