Lactobacillus gasseri (L. gasseri) is a probiotic bacterium that is found naturally in the genital, urinary, and digestive systems of the body. It is also present in breast milk, fermented foods, and dairy products. L. gasseri serves many important functions in the body, but the reason it has been one of the most talked about probiotic strains in the last few years is because of its correlation to weight loss and obesity treatment. There have been numerous studies to support this. We will talk about just a fraction of them here.
L. gasseri helps to control obesity, weight loss, and cholesterol
Several studies have shown that L. gasseri may reduce adiposity (fat), body weight, and weight gain. These results suggest that L. gasseri could be applied to the treatment of obesity, and it could also have a beneficial influence on metabolic disorders. Here is another study demonstrating weight loss in obese humans and animals from L. gasseri administration. In this trial, supplementation resulted in a modest decrease in weight, waist circumference, and hip circumference in obese and overweight adults with no behavioral or dietary changes.
L gasseri can significantly prevented body weight gain, fat accumulation and pro-inflammatory gene expression in the adipose tissue. Lower triglyceride levels and reduced expression of lipogenic genes were also observed in the liver. This study suggests that improvement in the inflammatory state of the adipose tissue might be a possible mechanism underlying the anti-obesity effect.
L. gasseri prevents inflammation due to high-fat diets and has a suppressing effect on blood glucose levels. It has also demonstrated an ability to improve diabetic symptoms in diabetic mice and reduce insulin levels. Total blood cholesterol, LDL cholesterol, and triglycerides in hypercholesterolemic men and women were reduced through a combination of L. gasseri and inulin. Other studies have also shown that L. gasseri is capable of reducing blood and liver cholesterol.
In addition to benefits associated with weight loss, anti-inflammation, and cholesterol, L. gasseri provides several other potential benefits. It has been shown to enhance immunity in the elderly by increasing T cell count. Some studies also indicate an ability to protect against influenza. L. gasseri can help with asthma by attenuating allergen-induced airway inflammation. It also may be able to enhance oral tolerance of allergies by increasing the number of regulatory T cells, and some studies indicate that it could help to combat fatigue in athletes after strenuous exercise.
Beneficial functions for probiotics tend to have some overlap between strains, but no other strains have as much well-documented research supporting weight loss and obesity control as L. gasseri. It could be a very important component of weight loss regimens in the future, so make sure you don’t forget about this strain when considering probiotic supplements.
