Intermittent Fasting and Heart Health: Study Raises Concerns
Intermittent fasting is a popular way of eating where you have periods of eating and not eating.
A new study looked at people who ate all their food within an 8-hour window.
The study found that those people had a greater chance of dying from heart problems compared to those who ate over a longer time.
This was especially true for people with diabetes, smokers, and those with existing heart conditions.
Experts suggest that if you have heart problems or diabetes, you should talk to your doctor before trying it.
It is important to focus on the quality of your food and consult your doctor.
A new study suggests that an 8-hour eating window is linked to a higher risk of cardiovascular disease.
The study analyzed data from over 19,000 adults in the US over eight years.
Participants with an 8-hour eating window had a 135% higher risk of death from cardiovascular disease.
Smokers, people with diabetes, and those with existing heart conditions were at higher risk.
Experts recommend personalized advice and caution for those with health issues when considering intermittent fasting.
