Intermittent Fasting May Double Heart Disease Death Risk, Study Says
Imagine your body like a car.
Intermittent fasting is like deciding when the car gets fuel.
A new study found that eating all your food within an 8-hour window each day (16 hours fasting) might be bad for your heart, like using the wrong fuel.
The study looked at many people and saw that those eating this way were more likely to die from heart problems.
Experts say be careful, because it's not proven to be good for you long term, and could cause problems.
They also say that not everyone should try it, especially those with health issues.
A study links eating for less than eight hours daily (16-hour intermittent fasting) to a higher risk of cardiovascular mortality.
The study analyzed data from the US National Health and Nutrition Examination Survey, involving 19,000 adults.
Researchers found no link between intermittent fasting and cancer or all-cause mortality.
Experts caution against long-term use of short eating windows due to potential risks and lack of evidence.
Intermittent fasting may not be suitable for individuals with pre-existing health conditions or certain demographics.

Risk Assessment
Cautious Approach
Intermittent fasting is a promising tool but requires careful assessment due to the absence of long-term data.
Potential Health Concerns
