The benefits and drawbacks of intermittent fasting for health and wellbeing are hotly debated. There is conflicting data regarding its benefits for weight loss, despite studies showing short-term benefits including lower cholesterol when people eat within a 10- to 12-hour window or enhanced gut microbiome in obese persons.
Intermittent fasting has also been demonstrated in certain studies to help lower blood pressure and cholesterol, two heart disease risk factors. A new paper, however, indicated that eating within an 8-hour window may increase the risk of cardiovascular death by as much as 91%. The poster was presented at the EPI Lifestyle Scientific Sessions 2024 in Chicago.
The body can be affected by intermittent fasting (IF) in a number of ways, including possible consequences on heart health. According to some research, there may be cardiovascular advantages to intermittent fasting, including lowered blood pressure, improved cholesterol, and increased weight loss—all of which can enhance heart health. But it’s important to proceed cautiously with intermittent fasting and take into account personal health circumstances.
Intermittent fasting might not be appropriate for everyone, particularly for those with specific medical concerns including diabetes, eating disorders, or a history of heart issues. Prolonged or severe fasting without adequate nutrition or hydration can cause electrolyte imbalances, dehydration, and other health problems that may have an indirect effect on heart function.
Before beginning intermittent fasting, like with any dietary or lifestyle change, it is imperative to speak with a healthcare provider, particularly if you have underlying health issues. They can offer you individualized advice based on your medical background and assist in determining whether intermittent fasting is suitable and safe for you.
