Will a High-Fiber Diet Help you Lose Weight? The Answer’s in Your Poop!
A new scientific report shows that something as simple as a fecal sample can show whether you can lose weight by following dietary recommendations including high fruit, vegetables, fiber and whole grains.
Disruptions in the gut microbiome (dysbiosis) have been linked to the growing prevalence of obesity and diabetes. As a result, scientists are now actively researching the microbiome looking for potential treatments.
In a new study published in the International Journal of Obesity, scientists show that the relationship between two groups of gut bacteria is an important indicator of whether people will lose weight on diets high in fruit, vegetables, fiber and whole grains (Danish national dietary recommendations).
In the study, 31 volunteers followed the Nordic diet for 26 weeks and lost an average of 3.5 kg (7.7 lbs).
Twenty-three volunteers eating an average Danish diet lost an average of 1.7 kg (3.75 lbs).
The high-fiber diet was twice as effective as the standard diet!
In addition, scientists monitored the microbiomes of the volunteer dieters.
When the microbiomes of the volunteers were analyzed the scientists discovered that people with a high proportion of Prevotella bacteria in relation to Bacteroides bacteria lost an extra 3.5 kg (7.7 lbs) in 26 weeks on the high-fiber diet.
People with a low proportion of Prevotella bacteria in relation to Bacteroides bacteria did not lose any extra weight.
The high proportion of Prevotella bacteria in relative to Bacteroides bacteria made the high-fiber diet four times more effective than the regular diet!
Approximately 50% of the population has a high Prevotella to Bacteroides ratio. Therefore, these people will benefit significantly from this type of high-fiber diet. The other 50%, unfortunately gain no extra benefit.
This study is a major step forward for personalized nutrition guidance.
The University of Copenhagen has licensed a Boston (USA) company to develop a concept based on this research that will benefit obese people.
