Can Bacteria Actually Help Us Regulate Our Body Weight?

We all know that antibiotics are great for fighting infection and disease, but has our increased use of them actually killed off some of our “good” bacteria as well? According to Melinda Beck’s article, “In the Gut: The Mix of Bacteria Can Affect Weight:, our use of antibiotics may actually be reducing our production of good microbes like those in the Christensenellaceae family, whose presence seems to correlate with how lean someone is. Numerous studies have been performed on mice that include the insertion of these microbes and they have concluded that there are more Christensenellaceae present in those that are leaner. So, being obese may be genetic! Those that are born with more of these microbes are generally seen to be thinner even when consuming the same diet; this was seen in a study performed at Cornell University observing identical twins. When one twin was obese and the other was not, a greater amount of these microbes was present in the leaner twin. But, as a whole other bacteria seem to be disappearing as well like the bacteria that helps control appetite, which our obesity issue can partially be attributed to. In fact, only 6% of US children are observed to have quantifiable amounts of these appetite bacteria in them. Thus, showing that the bacteria in us can have a role in our body weight. Though the role of bacteria in regards to our health as a whole is not fully explored yet, we can see that it can make a big difference.
