The numbers are astonishing: In spite of having about 10 trillion cells in your body, you have about 10 times more micro-organisms living in your gut.
Most of these bacteria live in your digestive tract and help break down your food, absorb vital nutrients and make key vitamins.
But in recent years, scientists and researchers have realized these bacteria do more than just help your digestion — they interact with cells that influence your energy levels and how you store fat.
Now there’s new evidence that adding more of these beneficial bacteria — in the form of probiotics — may help you lose weight and resist the storage of extra fat.1, 2
Probiotics May Cut Risk of a Fat Belly
In a study from the European Association for the Study of Obesity, researchers discovered that pregnant women who took certain probiotics were far less likely to be obese or have a fat belly one year after giving birth.3
In the study, 256 women were divided into three groups:
- Group 1 received dietary advice and daily capsules of probiotics.
- Group 2 received dietary advice and received placebo pills (no probiotics).
- Group 3 was not given dietary advice but also received placebo pills.
After one year, the researchers measured the women for what they call “central obesity,” the accumulation of abdominal fat resulting in an increased waist size. This is a form of obesity that is correlated with cardiovascular disease.
The results were very interesting!
The women who took the real probiotics and not the placebo were more than 41% less likely to be obese than the women who received the placebo pills.
That means the women taking the probiotics significantly cut their risk of being fat.
While there isn’t enough proof to call this a sure thing, there are other studies that suggest probiotics can help you slim down:
- A study from 2010, published in the European Journal of Clinical Nutrition, followed 87 people for 12 weeks as they drank fermented milk enhanced with a probiotic called Lactobacillus gasseri (LG2055). Compared to the control group, the people taking the LG2055 lost more body weight and belly fat.4
- An animal study published in the journal Microbiology showed that a specially-engineered probiotic had an impact on the metabolism and fat composition of mice. The authors of the study concluded that the probiotics may play a role in preventing obesity.5
- Another curious study published in the Journal of Gastrointestinal Surgery followed patients recovering from gastric bypass surgery. Split into two groups, the patients who received the probiotics showed significantly greater weight loss than those who didn’t.6
These studies tell us that probiotics may be a viable way to help control weight gain, and could even help you get rid of some belly fat.
The number of published studies is still limited, but I’m excited by the possibilities. I’m currently exploring different strains to find the best combination for weight loss, and when I find something worth recommending, I’ll let you know in a future blog post.
If you are a doctor or healthcare professional and have any ideas or input, I’d be happy to hear from you. Send me an e-mail at: email@example.com
Otherwise, I’ll keep you posted… so check back for updates.
Until next time,

Hi, I'm Dr. Steve Sisskind, Chief Medical Officer & Founder at RealDose Nutrition.
As a young physician, I struggled because my patients came to me with serious health issues, but I didn't have the right tools to help them. Medical school taught me how to put "band aids" on their symptoms with drugs and surgery, but not how to address the root causes of their problems.
Years later I discovered a better approach... based on the fundamental idea that the power of nutrition can transform your health and vitality. But there's a lot of confusion... What foods should I eat? Which supplements should I take? What does the science say?
I have dedicated my life to answering these questions... And I share this knowledge with you every day here at RealDose Nutrition.
I invite you to connect with me by joining my free private community. I've helped thousands of people and I know I can help you too!
