In a systematic review of gut microbiome in the international journal of endocrinology,10 researchers discovered that the bacteria in the gut of those who were obese were completely different from the gut bacteria of those who were skinny. But the researchers went further and isolated the exact bacteria responsible for keeping people skinny and then implanted them in the gut of overweight people. And guess what happened? The overweight people all lost weight without changing their diet or exercising at all.
How Your Gut Microbiome Affects Your Weight Gain You might be a little confused at this point because in the last chapter I said fat gain is caused by insulin, and now I’m saying it’s caused by gut bacteria. The fact of the matter is it is not only one or the other responsible. These issues are totally interrelated and play interconnected roles in helping you stay healthy and lose weight. Like I said before, you have literally trillions of bacteria living in your intestines in their own little ecosystem known as the microbiome. Some are friendly and helpful, and others not so much. But when they are in balance, they can live together harmoniously and keep your body humming along. You can imagine that if the microbiome gets out of balance all sorts of things start going wrong. Job one for the friendly bacteria is to help you break down and assimilate the nutrients from the foods you eat. But these good bacteria also play two other very important roles related to overall good health and success at weight loss.
