New Research Supports the Link Between Probiotics and Weight

By Elisa - Jenny Craig

Many of us have heard the term 'probiotics' tossed around by doctors or peers, or plastered on labels at the local grocery store touting benefits of digestion and beyond. But what exactly are probiotics, and what part do they play in a healthy diet? Read on as we discuss the benefits and growing research around this beneficial belly bacteria.


Probiotics_FoodSources.jpgSimply put, probiotics are the "good bacteria"1—the little guys that keep your gut health in tip-top shape, helping to balance the “good” and “bad” bacteria in your body. Your body needs an adequate amount of positive bacteria to stay healthy, so probiotics, whether occurring naturally in food or supplement form, may potentially boost your overall well-being2. The most widely known food source of probiotics is yogurt; others include some cheeses and other dairy products3. Another source—Kombucha—a drink rising in popularity, is also loaded with the beneficial bacteria.


Getting enough probiotics benefits your body in a number of ways, including promoting efficient digestion4. Because they contribute to the makeup of your gut health, probiotics may help monitor appetite and digestion from the inside5. Keeping your digestive system firing properly ensures that your body absorbs and processes all the key nutrients needed for healthy digestion and metabolism6—two things that also aid in maintaining a healthy weight.


Probiotics_HappyGut.jpgWhat’s more, new research7 indicates there may be a mix of bacteria in your gut that may help—or hinder—your weight loss efforts. The study looked at how gut bacteria works to turn the parts of food you can’t digest into energy you can use—and suggests, depending on the mix of bacteria you have, that they could impact how many calories are produced.8 So depending on your microorganisms’ efficiency, your own gut bacteria may be supplying you with additional, unwanted calories. While the researchers acknowledge these findings are preliminary, they concluded the development of new probiotics might help further individualize dietary weight loss plans in the future.


Another potential health benefit from probiotics is its ability to reduce inflammation levels9. Chronic, high levels of inflammation in the body can impact digestion, the imProbiotics_EatingYogurt.jpgmune system and potentially the onset of a variety of diseases10. Probiotics are often considered an important component of promoting healthy digestion and while research is limited, findings have indicated that they may help reduce symptoms in conditions like irritable bowel syndrome11. By minimizing the inflammatory response inside your body, probiotics may help your system continue to process, absorb and excrete foods the way it should.


While more research on probiotics is needed to fully understand all of the health benefits, adding foods into your routine such as yogurt with live and active cultures is a great way to help keep your gut happy and your digestive process running smoothly.

I’ve been on Jenny Craig for 4 weeks and have not cheated with an hour everyday at the gym to only loss 8-9lbs.  Not the 16 lbs as promised, not even the average amount in the FINE print. This program is very expensive for such a little amount of weight loss and a ton of exercise.  ??? Would love to get my $159.00 refunded.  Nancy

Hi Nancy!  8-9lbs is a great weight loss in 4 weeks.  The 16lbs you are referring to is what some people did lose while on Rapid Results.  Weight loss is different for everyone, so we'd want to talk to you one on one about your concerns.  Please talk with your Consultant or give our Jenny Care team a call at 1-800-536-6922.  Thank you!
