There are so many diet plans out there suggesting different regimes to help you lose or gain weight, but which one is best for you?
However, researchers at the University of Copenhagen have found that microbes found in the gut may have a significant impact on an individual’s ability to lose or gain weight. 
The study investigated 62 participants who were instructed to follow either a New Nordic diet (fish, wholegrain, root vegetables and berries) or an average Danish diet (lean meats, coffee, lettuce and eggs) for 26 weeks. Participants were grouped based on ratios of two bacteria groups, Prevotella and Bacteroides.
They found that those who followed the New Nordic diet (a diet high in fibre and wholegrain) and who had a higher Prevotella to Bacteroides ratio, lost more body fat compared to those who followed the Danish diet and had the same bacteria ratio. When the ratios were reversed, there was no difference in weight loss between the diet groups.
The results show that gut microbes help contribute to an individual’s ability to lose weight and may be solace to those who have tried multiple diet regimes, yet have failed to lose weight.
This research reinforces the idea that diet plans are not a “one size fits all” and that nutrition should be personalised to the individual.
