New study reveals a significant drawback of intermittent fasting

Nowadays, many people turn to fasting as a means of losing fat. Not only does it aid in weight loss, but it is also associated with several other positive effects on one’s health.

Despite the fact that the body can endure a couple of days without food before entering a state of starvation, recent research has called into question the benefits of fasting when done under proper supervision.

According to a study conducted by researchers from Europe and the UK, short duration fasts may not provide as many health benefits as commonly believed. The study revealed that fasting for more than three days can lead to significant improvements in health.

Potential Negative Effects of Short Fasting on Health

During the study, the participants underwent a seven-day water-only fast and the researchers examined multiple bodily processes.

Surprisingly, changes were consistent among all 12 healthy participants, including five women and seven men. Blood samples were collected from all participants before, during, and after the study.

During an interview with ScienceAlert, Claudia Langenberg, an epidemiologist from Queen Mary University of London, shared her thoughts.

“For the first time, we’re able to see what’s happening on a molecular level across the body when we fast. Our results provide evidence for the health benefits of fasting beyond weight loss, but these were only visible after three days of total caloric restriction – later than we previously thought.”

The ScienceAlert was also informed by the authors of the study.

“Lack of food has been the default situation throughout human evolution, and our bodies are the result of a selection process for high metabolic flexibility to survive long periods without it.

“Our results provide the opportunity to systematically identify the potential health benefits from fasting and translate this knowledge into putative interventions, including for patients who cannot adhere to prolonged fasting schemes or fasting-mimicking diets.”

Fasts of longer duration can bring about alterations in the body and stimulate the generation of multiple molecules that have the potential to enhance our well-being.

Despite the potential benefits, experts caution against certain risks associated with water fasts. Going without food for more than 48 hours can lead to calorie deprivation and may have negative effects on certain individuals, causing feelings of fatigue and weakness.

Additionally, extended periods of fasting may result in dehydration, regardless of your water intake, as proper hydration also relies on food consumption. The potential dangers associated with this type of prolonged fast have not been extensively researched and should be thoroughly examined. If you plan on incorporating intermittent fasting into your routine, it is important to do so under the guidance of a certified professional.

To ensure your well-being, make sure to consume sufficient fluids and electrolytes. If you experience any discomfort, seek advice from your nutritionist or doctor. Under proper supervision, short-term intermittent fasts can still yield some advantages.

If you are unable to go for a long period of time without eating, you can also opt for smaller meals.
