Jan. 28, 2014 - Certain probiotics could help women
– but not men - lose weight and keep it off, according to a recent study
published in the British Journal of Nutrition by a team of
Canadian researchers, who were joined by Swiss researchers from the
Nestlé company, which owns the probiotics used in the study.
Studies have already demonstrated that the
intestinal flora -
the bacteria normally within the lumen of the intestine - of obese
individuals differs from that of thin people. That difference may be due
to the fact that a diet high in fat and low in fiber promotes certain
bacteria at the expense of others. The reseach team tried to determine
if the consumption of probiotics could help reset the balance of the
intestinal microbiota (microscopic living organisms) in favor of bacteria that promote a healthy weight.
To test their hypothesis, researchers headed by
Université Laval (Quebec City, Canada) Professor Angelo Tremblay
recruited 125 overweight men and women.
The subjects underwent a 12-week weight-loss diet,
followed by a 12-week period aimed at maintaining body weight.
Throughout the entire study, half the participants swallowed 2 pills
daily containing probiotics from the Lactobacillus rhamnosus
family, while the other half received a placebo.
Editor’s Note: The Lactobacillus rhamnosus
strain used in this study belongs to Nestlé, which uses it in certain
yogurts it makes for the European market, but Professor Tremblay
believes that the probiotics found in dairy products in North America
could have a similar effect to the Nestlé strain. He stresses, however,
that the benefits of these bacteria are more likely to be observed in a
favorable nutritional context that promotes low fat and adequate fiber
After the 12-week diet period, researchers observed
an average weight loss of 4.4 kg in women in the probiotic group and 2.6
kg in the placebo group.
However, no differences in weight loss were
observed among males in the two groups. "We don't know why the
probiotics didn't have any effect on men. It may be a question of
dosage, or the study period may have been too short," says Professor
Tremblay, who is also the Canada Research Chair in Environment and
After the 12-week maintenance period, the weight of
the women in the placebo group had remained stable but the probiotic
group had continued to lose weight, for a total of 5.2 kg per person. In
short, women consuming probiotics lost twice as much weight over the
24-week period of the study. Researchers also noted a drop in the
appetite-regulating hormone leptin in this group, as well as a lower
overall concentration of the intestinal bacteria related to obesity.
According to Tremblay, probiotics may act by
altering the permeability of the intestinal wall. By keeping certain
proinflammatory molecules from entering the bloodstream, they might help
preventing the chain reaction that leads to glucose intolerance, type 2
diabetes, and obesity.
In addition to Angelo Tremblay, the study's
coauthors are Marina Sanchez, Jean Doré, Vicky Drapeau, André Marette,
Geneviève Chevrier, and Emmanuelle St-Amand from Université Laval, as
well as nine researchers from the Nestlé Research Center in Lausanne,
Are Probiotics Good for Your Health?
By Josephine P. Briggs, M.D., Director,
July 18, 2013 - Probiotics are gaining in popularity in
the United States, and chances are you’ve heard about them as “good
bacteria” or seen them advertised in your supermarket’s yogurt aisle.
But what are probiotics, and do they have any real health benefits?
Probiotics are live microorganisms—bacteria, for
example—that are either the same or similar to microorganisms found
naturally in our bodies. Although we tend to think of bacteria as
harmful “germs,” many bacteria actually help the body function properly.
Probiotics are available as dietary supplements and in dairy foods, and
our research tells us that probiotics are among the top five natural
products used for children. It is important to note that the U.S. Food
and Drug Administration has not approved any health claims for
probiotics; however, there is some evidence that probiotics may be
helpful for conditions such as acute diarrhea, antibiotic-associated
diarrhea, and possibly atopic eczema.
information on NCCAM’s Web site about what the science says about
the safety and effectiveness of probiotics. I encourage you to take a
look at this information, particularly if you are considering a
probiotic dietary supplement, and talk to your health care provider. As
always, take care and be well!
Probiotics are live microorganisms (in most cases,
bacteria) that are similar to beneficial microorganisms found in the
human gut. They are also called "friendly bacteria" or "good bacteria."
Probiotics are available to consumers mainly in the form of dietary
supplements and foods.
5 Things To Know About Probiotics
Probiotics are live microorganisms (e.g., bacteria)
that are either the same as or similar to microorganisms found naturally
in the human body and may be beneficial to health. If you picture the
human body as a “host” for bacteria and other microorganisms, you might
have a better understanding of probiotics. The body, especially the
lower gastrointestinal tract (the gut), contains a complex and diverse
community of bacteria. Although we tend to think of bacteria as harmful
“germs,” many bacteria actually help the body function properly.
Probiotics are available to consumers in oral
products such as dietary supplements and yogurts, as well as other
products such as suppositories and creams. It is important to be aware
that the U.S. Food and Drug Administration (FDA) has not approved any
health claims for probiotics. Here are some other things you
is some evidence that probiotics may be helpful for acute diarrhea,
antibiotic-associated diarrhea, and atopic eczema (a skin condition most
commonly seen in infants).
Although some probiotic formulations have shown promise in research,
strong scientific evidence to support other uses of probiotics for most
conditions is lacking.
suggest that probiotics usually have few side effects. However, the data
on safety, particularly long-term safety, are limited, and the risk of
serious side effects may be greater in people who have underlying health
Probiotic products may contain different types of probiotic bacteria and
have different effects in the human body. The effects also may vary from
person to person.
are considering a probiotic dietary supplement, talk to your health care
provider first. Do not replace scientifically proven treatments with
unproven products or practices.
