Uno study conducted by the Seattle Institute for Systems Biology suggests that the composition of bacteria in the intestine, could affect an individual's ability to lose weight.
The results are preliminary but, by examining gut bacteria in people before starting a weight loss program, it could be predict weight loss.
A systematic review
The study looked at the gut microbiomes of people who took part in a wellness program in 2019. Participants had submitted a stool sample as part of a series of comprehensive tests that included blood metabolite and other measurements.
Researchers have examined the microbiomes of 25 of the participants in deep molecular detail, calculating the types of bacterial genes present in the sample through DNA sequencing. Fifteen of these individuals had lost weight with the wellness program, while the rest maintained a stable weight.
The researchers found that people who lost weight had a different gut composition; their microbiomes have been enriched with bacterial genes that divert dietary nutrients to microbes and stimulate their growth. The bacteria also had faster growth rates, including a bacterial group called Prevotella. The microbiomes of people who have not lost weight have been enriched with bacterial genes, which convert fiber into absorbable sugars.
The results
The results would suggest that people who lose weight might have a microbiome rich in fast-growing bacteria, which would promote weight loss. If there are the same results in larger studies, this could lead to new ways to predict weight loss by measuring the microbiome.
This study stands out from others because it has shown that the composition of the microbiome associated with weight loss it is independent of the initial BMI, body mass index, a measure of obesity and overweight.
