Fat and thin people have different gut. Intestinal microbiota in mice and humans is similar, it is dominated by bacteria Firmicutes and Bacteroidetes. At this point is not fully established, what type of bacteria is responsible for weight management. Some studies show a decrease in the number of Bacteroidetes in obese people, while others point to a reduced level of beneficial bacteria such as Lactobacillus.
Despite the fact that diet influences the composition of intestinal microflora, most studies agree that the microflora in itself has an effect on weight. Thus, changes in the intestinal microbiota can be an important part of a weight loss program.
Scientists have proposed several mechanisms by which the intestinal microflora can adjust the weight. Inflammation, energy from polysaccharides, insulin sensitivity, consumption and conservation of energy — all these processes are influenced by the intestinal flora.
What you eat affects the composition of the microflora, but one can also imagine a different hypothesis — that your flora partially determines what you eat. People with intestinal dysbiosis, and particularly with the increased growth of yeast often have cravings for sugar. Intestinal microflora may affect our eating habits, and thus plays a role and define our dietary preferences.
Obesity is hereditary, and the importance of the intestinal microflora in the process can not be underestimated. Flora passed from mother to child at birth, breast-feeding and the early years of life. The child is also in contact with microorganisms from other family members. In this way, "microflora of obesity" is transmitted to the child.
Differences in the internal microflora during the first year of life are associated with a higher risk of obesity in later years. Especially prone to weight gain children makes a low level of bifidobacteria.
Obese people tend to have a dysfunction of the intestinal flora with high concentrations of LPS-containing microbiota and methane-producing bacteria. LPS, lipidopolisaharidy, associated with obesity, intestinal ulcers and chronic inflammation of the subliminal.
Deriving free own microflora mice inoculated flora from obese or lean mice, leading to a significantly greater increase in the total amount of fat in those inoculated "microbiota obesity." Further studies in animals have shown that probiotic sapplimenty with lactobacilli and bifidobacteria help maintain a healthy weight and contribute to its decline. Cattle, which given antibiotics puts a lot of fat, and this is one of the reasons why these substances are often used in feedlots.
How to apply this in your weight loss program
A healthy diet with reduced consumption of sugar, processed carbohydrates, vegetable oils, anti-nutrients and similar substances, in itself will contribute to weight loss and a healthier gut.
Additional modifications of the intestinal flora may also be an important part of the plan to reduce weight. But here we must note that the mere use of yogurt will not produce any significant changes in most people. Minimally washed organic plants and plant products, fermented foods and probiotic sapplimenty — they are a good resource of useful bacteria. Prebiotics, soluble fiber, which feed the good bacteria can be found in the leek, the usual onions, apples, and other similar products.
