According to recent studies, the intermittent energy restriction (IER) diet, which is used to lose weight, drastically changes gut flora and enhances brain function.
Consequently, that might support people's attempts to lose weight.
Researchers examined blood levels, stool samples, and functional magnetic resonance imaging (fMRI) in order to ascertain the changes in gut flora and brain activity in 25 Chinese men and women who were obese and following an IER diet.
The participants' body mass index (BMI) ranged from 28 to 45, with an average age of 27.
The goal of intermittent energy restriction is to alternate between eating at maintenance calorie levels and eating in a calorie deficit.
Participants in the study reduced their calorie intake for 32 days during a high-controlled fasting period.
Expert opinions regarding the study on intermittent energy restriction diets
Dietitian Fit's Reema Patel, who practices in London, stated that she is not shocked by the study's considerable reductions in body fat percentage and weight.
According to Patel, who did not participate in the study, this is expected given the degree of calorie restriction. But the effect of nutrition on the brain and the stomach is fascinating, she continued.
The abundance of some gut bacteria has changed, with an increase in those that help the brain process emotion and learn, and a decrease in some that affect our desire to lose weight, according to Patel, who spoke with Healthline.
"Restricting food intake can have a surprising amount of influence, even though the mechanisms are unclear."
How IER modifies brain activity and gut microbiota
You may be asking yourself why using IER to lose weight appears to have this impact.
The first thing to understand is that the brain and gut are connected via a bidirectional communication channelTrusted Source. This essentially indicates that there is continuous two-way communication between the brain and the gut.
According to Patel, the stomach is sensitive to our emotions and thoughts, much as the brain affects how the gut functions.
When you fast, the body starts metabolising fat reserves instead of glucose as its main energy source. According to Parsad, this modification sets off a series of processes that include adjustments to neurotransmitter activity and hormone levels.
In the meantime, the gut microbiota reacts to varying nutrient availability because it is sensitive to alterations in dietary habits.

Attempting the diet of intermittent energy restriction
How should you start if you wish to give IER a try?
Parsad advises getting started gradually.
He advises, "Start with shorter fasting periods and gradually extend them over time." "This aids the body's adaptation to variations in the availability of nutrients."
Selecting foods high in nutrients is crucial to certain your body gets the vital vitamins and minerals it needs. According to Parsad, you should consume a lot of protein to promote the health and fullness of your muscles. It's also important to stay hydrated.
Above all, Parsad advises paying attention to your body.
"Observe signs of hunger and modify the length and level of fasting according to personal comfort and tolerance," he suggests.
However, a word of caution. According to Patel, there's a chance you could become nutrition deficient if your IER.
