Gut Bacteria In Slim People Extract More Nutrients

Beeftopia writes "Researchers discovered that inserting gut bacteria from obese people into mice without gut bacteria led to the mice becoming obese. Gut bacteria from slim people inserted into the same mice did not lead to mouse obesity. The researchers concluded (abstract) that gut bacteria from the slim people were more efficient at extracting nutrients from food than those of the obese."

    It's not that they're better at extracting nutrients, it's that they influence the body to expend more or less enery. The nutrient extraction is a side effect.

    I do wish researchers would read the relevant literature before jumping to conclusions.

      No, I wouldn't be surprised, I've seen it and lived it (including the non-lasing lasers you speak of!). Sad thing is that I'm about to reject a paper I'm currently reviewing not because of the science (which is sound) but because it's so poorly written as to be almost unreadable. The problem is that there are people who learn how to wave their hands really well and make lots of friends who help pass this tripe through the peer review process, and many decent scientists who don't write "too good."

      Gut bacteria feed themselves, not you.

      More efficient or effective gut bacteria eat your lunch before you can.

      While in our overfed society, having hyperactive gut bacteria keeping you thin would be good, fatties would be laughing in a major disaster, since they'd get to enjoy more of that roadkill dinner they scavenged, and they'd have longer reserves for the initial disaster and the ensuing survival training course.

      Now if we could just toggle between two sets of bacteria, we'd have a pretty ideal setup!

      PH of a very acidic soda = 2.522, PH of stomach acid = 1.35

      Don't blame the soda for having an acidic stomach.

      If you drink something acidic, the total acidity level of your stomach will be more than if you drink water.

      That last statement is correct, but your stomach will still be less acidic than if you drank nothing, so it doesn't support the original statement that drinking soda makes your stomach more acidic as drinking anything less acidic than stomach acid will always make your stomach less acidic. There are a bunch of reasons why drinking lots of soda isn't a good idea, but acidifying your stomach isn't one of them.

      It isn't quite as easy as you might indicate.

      I'm 40 and eat a better balanced diet than when I was 20. I exercise, but weight has gradually increased over time. I was at the bottom end of normal for what BMI charts say I should have been @ age 20. I am now about 15 lbs into the "overweight". My doc says I am fine because I have more muscle, but he wants me to hold the line.

      I made some changes to exercise, working out 5 times a week in the morning and cutting out all soft drinks and after dinner snacking. I dropped 5 lbs in two weeks. i was hydrating a lot so it wasn't water that caused the drop.

      After two weeks, same diet same exercise I dropped 5 more pounds in two weeks. I was feeling great. I was hoping for another 10. But guess what? Two months later, same diet same exercise I didn't drop a single pound. I am not sure how to explain it. It is like my body reached a certain point and compensated for the caloric drop by going into a lower metabolism rate.

      When I was 20 I couldn't gain weight no matter what. Now, I know that 160# is a place that my body just doesn't want to drop below. I understand that I could increase exercise more or cut out even more food... but is it worth it?

      I am convinced that BMI might be a guideline, but it isn't gospel. I can still run a mile at a good clip and keep up with the kids. What am I gaining by dropping into a somewhat arbitrary scale if I am healthy already?

    So the mice became obese after being injected with gut bacteria from obese people. But the mice that were injected with gut bacteria from non-obese people did not. Or put another way, before the injection the mice were not obese, and after the injection the mice were still not obese. Since those mice experienced no change whatsoever, it makes no sense to conclude that the non-obese bacteria is more efficient at extracting nutrients. If that was the reason for the change, shouldn't there be some difference after the injection of the non-obese bacteria?

    Could antibiotics make you fat?

    Two studies this week suggest that using antibiotics may save people’s lives, but could also change their metabolisms. Put together, the studies suggest that taking antibiotics might alter digestion to help people absorb calories from food they normally would be unable to digest.

    Every human carries pounds of microorganisms that we couldn’t live without. They break down food and extract nutrients like Vitamin K for us. Antibiotics will kill some of these beneficial organisms, which is why so many doctors now tell patients to eat yogurt after taking a course of the drugs, to replace some of the good guys.
