|Some people seem to just not be able to lose their extra pounds, even though they consume no carbohydrates or sugars, hold a strict diet and do sport. In actual fact the intestinal flora can be the cause. Scientific studies have shown that, in comparison to people with normal weight, overweight people have a totally different distribution of gut bacteria. Gut bacteria can be split into two groups, bacteroidetes and firmicutes which should, ideally, have the ratio of one to one. By overweight people this balance tends to be shifted in favour of the firmicutes. Firmicutes have the characteristic of being able to extract as many calories as possible from food. They can even convert dietary fibre, which is not normally digestible, into calories. As a result, people who have more firmicutes in their intestine tend to absorb more calories although they may not eat more. Therefore: The lower the weight, the higher the percentage of bacteroidetes and the lower the percentage of firmicutes.
A simple test allows us to examine whether someone utilises their food well, and as a result is absorbing too many calories. Verisana offers a stool test which can determine the balance between firmicutes and bacteroidetes (adiposity index). The ratio between both types of bacteria can serve as a basis for a change in diet and the administration of probiotics.
