Researchers have found that probiotics may help children and adolescents with obesity lose weight when taken alongside a calorie-controlled diet.
Foods that broaden the profile of helpful bacteria in the gut are collectively known as probiotics. These “good bacteria” can be taken as supplements, or found naturally in yogurts or fermented foods.
The study, presented at e-ECE 2020 online conference on Tuesday, found that obese children who were put on a calorie-restricted diet and given probiotics Bifidobacterium breve BR03 and Bifidobacterium breve B632, lost more weight.

“These findings suggest that probiotic supplements and a calorie-controlled diet may help manage obesity in the younger population and reduce future health risks, such as heart disease and diabetes,” said study authors from the University of Piemonte Orientale in Italy. According to the researchers, a Bifidobacteria are a group of probiotic bacteria that are part of the natural gut microbiome and help with preventing infection from other bacteria, such as E.coli, and digestion of carbohydrates and dietary fibre.
During digestion, they release chemicals called short-chain fatty acids, which play an important role in gut health and controlling hunger. Low numbers of Bifidobacteria may impair digestion, affect food intake and energy expenditure, leading to body weight gain and obesity.

Previous studies suggested that probiotic supplementation with Bifidobacteria could help restore the composition of the gut microbiome, which may aid weight loss and could be a potential approach for obesity management. However, current research uses mixtures of different strains of probiotics and does not examine the effects of administering Bifidobacteria alone. For the current results, the team aimed to assess the impact of Bifidobacteria probiotic treatment in children and adolescents with obesity on a controlled diet, on weight loss and gut microbiota composition.
At least 100 obese children and adolescents (6-18 years) were put on a calorie-controlled diet and randomly given either probiotics Bifidobacterium breve BR03 and Bifidobacterium breve B632, or a placebo for 8 weeks. Clinical, biochemical and stool sample analyses were carried out to determine the effect of probiotic supplementation on weight gain, gut microbiota and metabolism.
The results suggested that children who had taken probiotics had a reduction in waist circumference, BMI, insulin resistance and E.coli in their gut.
These beneficial effects demonstrate the potential of probiotics in helping to treat obesity in children and adolescents when undergoing dietary restrictions.
“Probiotic supplements are frequently given to people without proper evidence data. These findings start to give evidence of the efficacy and safety of two probiotic strains in treating obesity in a younger population,” the team noted. (IANS)
