Thanks to health-related social media influencers, intermittent fasting has become a big buzzword. From losing weight quicker to improving your energy levels, the benefits of intermittent fasting have made everyone curious about this type of fasting method.
However, is it completely safe?
A recent study that came out in the public domain has linked intermittent fasting to growing heart-related conditions. This information has left the internet divided. One section claims the study is not authentic enough and the other says it’s a big conspiracy by global food brands that want you to stop fasting and start consuming their products.
But who is telling the truth? Let’s dive into some real facts, debunk some common myths, and go through practical ways to help you fast safely and effectively.
Understanding Intermittent Fasting and Heart Health
What is Intermittent Fasting?
Think of intermittent fasting as an eating pattern. In this pattern, you switch between eating and not eating. You schedule your meals in a way that gives your body a good amount of break from food for certain hours of the day or days of the week. Here are some popular methods:
- 16/8 Method: You eat all your meals within an 8-hour window (from 12 PM to 8 PM) and then fast for the remaining 16 hours.
- 5:2 Diet: You eat normally for five days of the week and then eat very few calories (like 500-600) on the other two days.
Health Claims and Concerns
The people who promote intermittent fasting claim it helps with weight loss, improves metabolic health and may even extend lifespan. However, some studies have raised concerns related to intermittent fasting and heart diseases. It suggests a potential link between intermittent fasting and increased heart disease risk.
The Controversial Study: Fasting and Heart Disease
What the Study Found
A new research article published in the Journal of the American Heart Association indicates there could be an association between intermittent fasting and heart disease. Their study included a cohort of almost 20,000 participants. Over several years, their eating habits and heart health were carefully studied.
Key Findings
The study indicated that people who followed time-restricted eating as part of intermittent fasting by eating all their meals within an 8-hour window had a high chance of developing heart-related diseases.
The study also revealed that there is a 91% higher risk of death from cardiovascular disease among people who followed this fasting method compared to those who ate over a longer period of 12-16 hours per day.
However, does this mean intermittent fasting is the sole reason behind this increased risk? A Big NO!
Factors Questioning the Findings
- Methodology: The researchers studied the participants’ diets and heart health, but they didn’t cover everything. For Instance, the overall quality of their diets or levels of physical activity of participants was not considered in the study.
- Correlation vs. Causation: Just because fasting and heart disease were linked doesn’t mean fasting causes heart disease. Many other factors which were not considered during the study could be potentially linked to heart diseases.
Responses from the Medical Community
The study has sparked various responses from doctors:
- Dr Victor Zhong, the study’s lead author, emphasized that while the findings are significant, they don’t mean everyone should avoid intermittent fasting. “Our study encourages a cautious, personalized approach to dietary recommendations,” he said. “We need to ensure that dietary plans align with an individual’s health status and the latest scientific evidence.”
- A functional medicine practitioner, Dr. Mindy Pelz noted that the study doesn’t prove fasting is harmful. “Many participants were smokers, which could have skewed the results,” she explained. “This study shouldn’t scare people away from intermittent fasting, but it does highlight the need to consider overall diet quality and lifestyle.”
- Christopher D. Gardner, Ph.D., from Stanford University, pointed out the need for more long-term research. “It’s crucial to look at the nutrient quality of the diets and consider comprehensive demographic comparisons,” he stated.
In summary, while the study does show the need to be cautious, it doesn’t prove that intermittent fasting is bad for your heart. Always consult with a healthcare provider to see what’s right for you.
