Matej Bajzer& Randy J. Seeley asked the question:

“The intestinal bacteria in obese humans and mice differ from those in lean individuals. Are these bacteria involved in how we regulate body weight, and are they a factor in the obesity epidemic?”

Bacteroidetes and Firmicutes have been shown to be distributed differently in obese and lean mice and obese and lean humans. But I can’t find any research that shows that those bacteria have a causative effect on obesity. I have spoken with few people who share the same opinion I do… that is Obesity is the prime factor that determines the distirubution of these bacteria. I became interested in this subject because a few of my clients mentioned it and wanted my opinion.

Any thoughts would be appreciated.

Thanks

I remember reading this first on Lyle's boards. Seems to me the question is can these bacteria honestly affect calorie absorption to the point where it matters. The laws of physics don't change, but if one person eats a 400 kCal bowl of cereal and realistically only 'sees' 200 of those calories, and another person eats the same bowl and gets all 400 kCal, it's pretty significant. If the percentages are smaller in practical application I don't think it's that big of a deal.
 
Sorry to butt in here:

The role of these bacteria is to create a balanced ecological environment inside the gut, example the Escherichia coli (which are pathogenic) are kept under control by the various bacilli species, which secrete lactic acid, then there are also some species of Saccharomyces (yeasts) which help process the left over sugars from digestion.

To me, the obese patients would have a different gut content than the lean ones, by default, as obese people often tend to eat horribly wrong, many times causing terrible disruptions to the ecology of the gut.

All in all, this is almost "paralysis by analysis", as these "little guys" can hardly influence the regulation of body weight, that is solely accomplished by correct eating, which in turn will help the ecological population perform at its best.

The gut bacteria regulate digestion and subsequently excretion, and if fed the right stuff will perform at their best. That simply means your digestion will be better.

The only implication to weight regulation will be that obese people will also suffer from constipation to a degree and will therefore keep some amount of weight (disgested matter not excreted), maybe leading some uninformed people to think along those lines.

Although I am not the coach, but I am a microbiologist, so I'll give my opinion, pro-biotics are great to improve the last part of our digestive system (the excretory system, specifically the gut part of this sytem alone, as there is more to it than that).

Taking them regularly will help to maintain a healthy gut ecology which is important to digestion, if digestion works at its best, absorption of nutrients will be enhanced, help the whole body to perform better.

That is just my opinion!
