Gastric bypass changes gut microbes and helps weight loss

Post by Zizzle »

I'm not sure what to make of this research. I guess it's news that having intestinal surgery changes the bacterial composition of your intestines? Or does having to eat tiny quantities after the bypass surgery change the microbial composition of your gut?

I fail to see how that's a remarkable discovery. Absolutely anything done to alter the gut architecture and/or the diet is naturally going to alter the gut bacteria demographics. :shrug: That's a ho-hum "discovery", IMO.

I am wondering if some obesity is caused by bacteria in the gut. This might be a step toward that.
I do understand about calories in and out. I worked for Weightwatchers for a while. I am currently at a good weight for me and don't want to lose more.

There's certainly an association, though a lot of this is mostly speculation based on circumstantial evidence:

Microbes in our gut regulate genes that control obesity and inflammation

Healthy gut flora could prevent obesity, rat study suggests

Gut organisms could be clue in controlling obesity risk

But the bottom line is that those bacteria are there for a reason — the carbs in our diet attract them and allow them to thrive. So it's the diet that's the problem, not the bacteria. If we get rid of the bad carbs, we get rid of the obesity-promoting bacteria.
