Several studies are now pointing to the possibility that your microbiome, or all of the bacteria that live on and in your body, may hold key positions in determining your weight. Microbes outnumber your human cells by ten-fold. That means there is more of them than you. Our microbiome is established our first year of life through the birth canal, diet, and antibiotic use.

Microbiome and Antibiotics

One study explored children who took a lot of antibiotics as babies and found that they were more likely to be overweight. This would seem to make sense if the antibiotics “took out” all of the gut flora, both good and bad, then there is a possibility that losing some of those good bacteria has an adverse effect.

After all, bacteria help us to digest food, provide vitamins, and protect us from other pathogens. If these bacteria get destroyed, you could have problems such as Crohn’s disease, ulcerative colitis, and now perhaps, obesity. (How to cleanse your digestive tract safely)

While the studies into this interesting field continue, you may want to repopulate your intestinal flora. There are some very simple things you can do such as eating more fermented foods like sauerkraut or kimchi.

There are also pro biotic pills and yogurt you can have daily to help regulate your gut. Other things that influence the human microbiome are pesticides, pollutants, and chemicals so eating clean and organic might be an option to improve your flora.
