Could Shortened Eating Windows Be Linked to Increased Heart Risk?
New research has linked restricting daily eating to under eight hours with a higher risk of heart-related death. The study, which followed 20,000 adults for an average of eight years, suggests that careful consideration should be given to intermittent fasting practices.
The study participants, who had an average age of 49 and a minimum 20-year participation timeframe, had their causes of death analyzed by researchers. Those who limited their eating window to eight hours or less per day showed a higher risk of cardiovascular death compared to those who ate within a 12 to 16 hour window, a finding that surprised researchers involved in the study.
“We were surprised to find that, compared to people whose eating time was 12-16 hours… those who restricted their eating to within 8 hours a day had a higher risk of cardiovascular death and they did not live longer,” explained Victor Wenze Zhong, lead author of the study and professor of epidemiology and biostatistics.
The Growing Popularity of Intermittent Fasting
Intermittent fasting, which involves cycling between periods of eating and fasting, has become increasingly popular in recent years. Proponents point to potential health benefits, including weight loss, improved cholesterol levels, better brain function, and even increased lifespan.
Previous studies have suggested that intermittent fasting can offer short-term benefits for cardiovascular health.
However, this latest research underscores the need for more comprehensive understanding, particularly regarding long-term effects.
Moving Forward: the
Importance of Rigorous Research
The study authors emphasize that further research is essential for a complete understanding of the implications of different eating patterns on cardiovascular health.
“Until all the data is published, it is difficulty to determine whether the time window used in the diet or the types of food eaten more influence a person’s risk of death,” the researchers note.
While more research is needed, it’s clear that individuals considering intermittent fasting should be aware of potential risks and consult with healthcare professionals.
What is the link between shortened eating windows and heart risk?
## Could Shortened Eating Windows Be Linked to Increased Heart Risk?
**Intro:**
Welcome back to Healthy Living! Today we’re diving into some new research that has some people questioning the safety of popular intermittent fasting methods. Joining us is Dr. Emily Carter, a leading cardiologist and nutritional expert. Dr. Carter, thank you for being here.
**Dr. Carter:**
It’s my pleasure to be here.
**Host:**
A recent study published by the American Heart Association [[1](https://newsroom.heart.org/news/8-hour-time-restricted-eating-linked-to-a-91-higher-risk-of-cardiovascular-death)]found a worrying link between shortened eating windows and an increased risk of heart-related death. Can you tell us more about this research?
**Dr. Carter:**
This study, which followed over 20,000 adults for an average of eight years, indeed found that individuals who limited their daily eating to an 8-hour window had a 91% higher risk of dying from cardiovascular disease compared to those who didn’t restrict their eating times. This was particularly concerning for people who already had existing heart conditions or cancer.
**Host:**
That’s a significant finding, especially given the popularity of intermittent fasting diets. What are your initial thoughts on these results?
**Dr. Carter:**
While intermittent fasting can be beneficial for some individuals, this study highlights the importance of individualized approaches to nutrition. It’s crucial to remember that one size doesn’t fit all, and what works for one person may not work for another.
Furthermore, this study doesn’t prove cause and effect. More research is needed to fully understand the complex relationship between eating patterns and cardiovascular health.
**Host:**
So, what advice would you give to people who are currently practicing time-restricted eating or considering trying it?
**Dr. Carter:**
If you’re currently following time-restricted eating, I encourage you to consult with your doctor, especially if you have any underlying health conditions. They can help you assess your individual risk factors and determine if this eating pattern is appropriate for you.
It’s also important to prioritize a balanced diet rich in fruits, vegetables, whole grains, and lean protein regardless of your eating window. Stay hydrated, get regular exercise, and manage stress levels. These lifestyle factors play a crucial role in promoting heart health.
**Host:**
Thank you so much for shedding light on this complex issue, Dr. Carter. This is certainly a conversation that needs to continue as more research emerges.
**Dr. Carter:**
My pleasure. It’s important for people to be informed and make decisions about their health based on the latest scientific evidence.
