Probiotics for Fat Burning and Weight Loss

There are more than 500 bacteria in the gut that help promote better digestion and a healthy immune system. Research shows that the normal bacteria found in the intestines, also known as intestinal flora, is different in thin and overweight people. Other studies show how incorporating certain probiotic supplements and foods into a healthy diet plan can aid in weight loss. Look to this information to see what some scientists have learned about probiotics and losing weight.

Probiotics Defined

Not all germs are bad for you. The word probiotics means “for life” and the health benefits of these live bacteria and yeast are abundant. These helpful germs come in many forms such as pills, powders, liquids and other supplements. Many foods contain probiotics as well including yogurt, sourdough bread, sour pickles, sauerkraut, miso, soy sauce and more. The scientific name of probiotics includes a capitalized and italicized genus, lowercase and italicized species and a number designating the strain.  The most well known genera of probiotics includes Lactobacillus and Bifidobacterium. Other beneficial probiotic include genera Bacillus, Saccharomyces, Streptococcus, Enterococcus and Escherichia.

Scientific Evidence

One 2013 study shows how consuming a probiotic supplements can help women lose weight. Marina Sanchez and colleagues followed 125 obese men and women for a 12 week weight loss diet period and another 12 week maintenance period. During the diet period, half of the group took two pills daily with the probiotic and the other half took a placebo. The team of scientists found that the women receiving the probiotics lost two times more weight than the placebo group of women. After the 12 week maintenance period scientists note a continued weight loss among the probiotic group while the placebo group maintained their weight loss. There was no clear difference noted among the men in either group.

Another 2013 research report by Yukio Kadooka and colleagues shows similar results. Scientists followed 210 overweight men and women for 12 weeks. They were divided into three groups. All groups drank seven ounces of fermented milk each day. Two of the groups had different amounts of Lactobacillus gasseri SBT2055 added to their milk and the last group was the control group. The adults in the two probiotic groups lost up to nine percent visceral fat and three percent belly fat. There was no significant change observed in the control group.

More research is needed to support all the health benefits that probiotics offer. The promising results like in the examples above certainly may encourage some to include more probiotics in their diet. It’s always a good idea to talk to a healthcare provider about dietary changes.
