What if our genes were governed by the bacteria in our bodies? This is the theory put forward by meta – genomics, or the study of the genome of micro – organisms ( mainly bacteria ) that would appear to interact with our own genes. It is said that they modulate our immune system, the way our brain functions and even their host’s weight gain. “We noticed that the flora in the mouths of obese and overweight people was imbalanced, with the presence of a large quantity of a particular category of bacteria,” says Dr Lavinia Ionita. “These bacteria slow down the basic metabolism and make people feel constantly hungry.” Restoring the right level of bacterial flora could therefore possibly be a good way to lose weight more quickly and optimise the way the whole body functions. Pending the advent of reliable tests, Dr Ionita recommends rebalancing the metabolism with liquid chlorophyll ( that can be made up by your local chemist ), a mix of pre – and probiotics ( Bionutrics UltraFlora Forte ) and a blend of plants ( Kapparest Energetica by Biotics Research ).
