Firmicutes are the nerds among the bacteria. They work meticulously and extract every single nutrient from your meals, no matter how tiny. As a result, you consume more calories than you actually want to. They like fat and sugar most, and they crave it vehemently. This means that you too will have a big appetite for sweets and fats. A vicious circle! As absurd as it sounds, but the Firmicutes bacteria don't want you to starve to death, so your fat cells should be full to bursting. Scientists have found out that the intestinal flora of overweight people is particularly rich in firmicutes. In slim people, on the other hand, a different strain of bacteria forms the majority: Bacteroidetes. These bacteria have the exact opposite effect.
