Probiotics reduce LDL cholesterol and help reduce and keep weight off
Probiotic reduces LDL cholesterol level 
Many people are aware that high levels of LDL, the “bad” cholesterol, raise chances for heart problems, but far fewer know that a healthy gut—the stomach and intestines—also plays an important role in maintaining heart health. Doctors in this study reviewed 26 clinical trials and two large meta-analyses on the effects of probiotics on LDL. Of all probiotic strains, L. reuteri lowered LDL and total cholesterol most, and reduced signs of inflammation significantly. Participants who took L. reuteri twice per day for nine weeks had levels of LDL cholesterol 11.6 percent lower than placebo. Discussing their findings, doctors said that people know probiotics for digestive health but do not think of probiotics for heart health, adding, “It’s time to recognize probiotics’ role as a simple and natural tool to manage cholesterol,” and recommend people add probiotics to their diet and exercise program to manage heart health.

Probiotics help reduce and keep weight off 
Earlier studies have found overweight people have less healthy bacteria in the gut than those who are healthy-weight. In this study, 125 overweight men and women ate a calorie-controlled diet for 12 weeks, followed by 12 weeks of weight maintenance. During the entire time, participants took lactobacillus rhamnosus or a placebo. After the first 12 weeks, while there was no effect in men, women in the probiotics group had lost 10 pounds, compared to six pounds for placebo. Over the next 12 weeks, the placebo group reversed their progress while the women taking probiotics continued to lose more body weight and fat mass. Doctors don’t know why the men didn’t respond to probiotics, but suggest the dose may need to be higher or the study period increased. Probiotics may alter the permeability of the intestinal wall, keeping inflammatory molecules from entering the bloodstream and helping prevent a chain reaction leading to glucose intolerance, obesity, and type 2 diabetes, doctors said.
