A new study has confirmed the link between balanced intestinal flora and weight loss.
Probiotics, known as â€œgood bacteria,â€ are thought to reduce the absorption of fat.
What we eat can radically change the nature of the bacteria which make up our intestinal flora, for better or for worse, and various studies have shown that many obese people have imbalanced intestinal flora.
Probiotics â€“ supplements that contain micro-organisms known as â€œgood bacteriaâ€ â€“ have been the subject of many experiments revealing their potential to rebalance our intestinal flora, resulting in weight loss.
In this new study, published in the journal Obesity, researchers at Virginia Tech in the US monitored 20 healthy men aged between 18 and 30 who followed a high-fat diet for four weeks. Some of them drank a milkshake containing VSL3, a probiotic with multiple strains of bacteria including Lactobacillus acidophilus and Bifidobacterium longum. The others drank a placebo milkshake.
The results showed that the men who drank the probiotic mixture put on less weight than the other group.
The researchers think that probiotics could have changed gut bacteria in a way that resulted in less body fat accumulation. They also hypothesise that the probiotics could have reduced lipid absorption or had an impact on energy expenditure.
Probiotics are naturally present in yoghurt and fermented milk, kimchi, tempeh as well as in miso paste and olives in brine. â€“ AFP Relaxnews
