How a probiotic helps to reduce weight?

Obesity is caused due to multiple reasons and the most common among them is an imbalance between how much calories one eats and how much one spends in form of exercise and daily activity.

With increasing affluence worldwide, there has been an increase in available food and sedentary nature of life which has lead to obesity pandemic as we are consuming more and working less. The probiotics act by numerous methods on our body metabolism to reduce the extraction of calories from the food we eat.

A probiotic is a live bacteria or yeast which is given as food because of its health benefit. It has been shown in studies that type of micro-organisms in our gut is related to our weight. Those who are obese have a large number of bacteria from the group called Firmicutes (-the bad bacteria) in the gut while those who are lean have large number of bacteria from the group called Bacteriodetes (-the good bacteria).

To reduce weight, the good bacteria are given as probiotic food as the good bacteria absorb less calories from the food we eat while bad bacteria absorbs more calories making one obese [R].

What are the best probiotic supplements for weight loss?

Most probiotic strains having beneficial effect on body metabolism in humans is reported from only two groups-Lactobacillus and Bifidobacterium.

This study underlines the importance of alteration of gut microflora by probiotics to prevent obesity since childhood.
