Best Probiotics Strains for Weight Loss

Probiotics are good bacteria that promote health and aid in digestion. These microorganisms have become quite popular among healthy eaters recently for their various health benefits especially using probiotics for weight loss. The digestive system requires a balance of good and bad bacteria to function properly. Multiple factors can disturb that balance and make bad bacteria prevail, and probiotics prevent the imbalance from happening.

Intake of probiotics is highly recommended to individuals with poor digestive health, weak immunity, and to people who want to have healthier gut flora. Assisting in weight loss is yet another important benefit of probiotics. You’ve probably heard of someone taking probiotics just because they want that extra kick to lose weight in a safe and natural way.

With a variety of probiotic types and strains, it is easy to get confused and wonder about the best strain for weight loss specifically. In this article, you’re going to learn more about the best probiotics for weight loss.


Which Probiotic Strains Helps With Weight Loss?

Strains from the Lactobacillus family prove to be highly effective for weight loss, particularly Lactobacillus gasseri. Out of all the probiotics studied so far, this particular strain shows the most promising weight loss effects.

A study whose findings were published in the British Journal of Nutrition found that rats that received this probiotic had lower cholesterol levels and increased excretion of fecal fatty acids, both of these factors are necessary for overall health, good digestion, and of course weight loss.

Moreover, the European Journal of Nutrition featured research which discovered that Lactobacillus gasseri prevents body weight gain, fat accumulation, and pro-inflammatory gene expression in the adipose tissue.

Japanese scientists discovered that the probiotic Lactobacillus gasseri shows lowering effects on abdominal adiposity, body weight and other measures, which is why it is beneficial for individuals who want to manage or prevent obesity and metabolic disorders.

The Korean Journal of Family Medicine presented research confirming that the administration of this probiotic strain reduces weight and waist and hip circumference.

Possibly the best piece of evidence confirming the efficacy of Lactobacillus gasseri comes from a study carried out by researchers in Japan who followed 210 participants with a lot of belly fat. Their findings, published in the British Journal of Nutrition, revealed that taking this probiotic strain for 12 weeks reduced body weight, fat around organs, BMI, waist size, and hip circumference. In fact, it reduced belly fat by 8.5%.

Although Lactobacillus gasseri is the most powerful probiotic for weight loss, you will achieve greater effects if you take products with multiple strains. Other strains that are beneficial for weight loss are Lactobacillus fermentum, Lactobacillus amylovorus, and Lactobacillus rhamnosus. That said, we can expect scientists to discover new, potent strains in the near future because there are many stains that haven’t even been identified yet.

How Do Probiotics Help with Weight Loss?

Successful weight loss is the result of regular physical activity and a well-balanced diet. Contrary to popular belief, however, you do not have to adhere to a strict and restrictive diet that can jeopardize your health in order to lose weight. The key is to limit or avoid the consumption of unhealthy foods while increasing the intake of healthy foods abundant in vitamins, minerals, proteins, healthy fats, and other nutrients. One of the healthy additions you should be making to your diet when you embark on your weight loss journey is probiotics. These live microorganisms can be of great help to your weight loss. Keep reading to find out how.

Top Benefits of Probiotic Supplements

In order to shed some light on the role of probiotics in weight loss, it is important to mention that a growing body of evidence suggests that overweight, particularly obese individuals, have different gut bacteria than people within the healthy weight range. A paper, published in the Journal of Obesity and Weight Loss Medication, showed that intestinal microbiota plays a vital role in regulating energy levels and metabolic pathways. Changes in gut microbiota have been observed in both obese animals and humans. Microbiota may modulate energy balance in your body through different mechanisms such as increased intestinal absorption of monosaccharides and the production of short-chain fatty acids through polysaccharides fermentation, and many others. Based on these findings, scientists from Italy concluded that the manipulation of gut microbiota is a useful manner of tackling or preventing obesity and metabolic disorders.

Why Is Using a Probiotic Supplement Beneficial?

Due to the fact that changes in gut microbiota can contribute to gaining weight, it comes as no surprise that scientists assumed probiotics may help prevent that. And it turns out that they were not wrong!

The British Journal of Nutrition featured a study which showed that certain probiotics can, indeed, help women lose weight. Not just that, they also help keep the lost weight off. Many people lose weight just to gain it all back. With probiotics, you can avoid this common problem, according to this study.

The study included 125 overweight participants who were assigned to two groups: one study received 2 pills daily containing probiotics while the second group received a placebo for two weeks. Results showed that after the 12-week diet period, women in the probiotic group lost about 4.4 kg while the placebo group lost only 2kg.

Scientists who worked on this study presume that probiotics promote weight loss by altering the permeability of the intestinal wall. Also, they keep some pro-inflammatory molecules from entering the bloodstream, thus preventing the chain reaction that leads to glucose intolerance, obesity, and Type 2 diabetes.

Women aren’t the only ones who can benefit from probiotics! Virginia Tech researchers carried out their own study which included 20 healthy men and found that probiotics prevent weight gain and fat accumulation. Why are probiotics so helpful? Well, overeating tends to alter microbiome communities and make it difficult for the body to absorb all the nutrients, but probiotics promote the balance of microbiota and, thereby, solve these issues.

Furthermore, a meta-analysis published in the Journal of Food Sciences and Nutrition found that consuming probiotics can reduce body weight and BMI (body mass index). The greatest reduction in BMI occurred in overweight individuals who consumed multiple probiotic strains.

Moreover, evidence suggests that certain strains of the Lactobacillus family promote weight loss and help people lose belly fat. In one study, strains from this bacterial family reduced body fat by 3-4% over a 6-week period.

So basically, probiotics support weight loss due to these reasons:

  • Better digestive health
  • The Balance of gut microbiota
  • They prevent pro-inflammatory molecules from entering the bloodstream and causing harm that could, eventually, lead to obesity
  • Better absorption of nutrients
  • Prevention of weight gain

Best Probiotic Strains to Increase Metabolism

We can divide probiotics into different families, and each of these families has multiple strains. Getting the right type of probiotic is crucial for weight loss because different strains serve different purposes. When it comes to weight loss, the Lactobacillus family is the one you should aim for as it helps you lose extra pounds and stubborn belly fat.

In the study mentioned above, the probiotic strains that led to a 3-4% loss in belly fat were Lactobacillus amylovorus and Lactobacillus fermentum. Yet another study published in the British Journal of Nutrition found that strain Lactobacillus rhamnosus helped participants lose 50% more weight than placebo during a 3-month period.

However, the probiotic strain with the greatest potential to aid weight loss is Lactobacillus gasseri. This particular strain helps you lose weight and belly fat, and it also prevents weight gain. Lactobacillus gasseri is found naturally in the digestive, genital, and urinary systems of the human body. This strain is also present in fermented foods and some dairy products, but you can also get it in supplement form.

Lactobacillus gasseri is one of the most well-researched probiotic strains, and it is widely known for its positive impact on weight loss. It is not uncommon for fitness professionals to include this strain in the regimens they plan for their clients because it supports digestive health, burns belly fat, and prevents fat production. Let’s not forget the fact that Lactobacillus gasseri reduces inflammation, lowers cholesterol, and regulates a hormone called leptin. Adipose (fat) cells produce this hormone to helps maintain energy by suppressing hunger. Overweight or obese individuals are, usually, desensitized to this hormone, which explains why they tend to overeat.

It is important to bear in mind that probiotics shouldn’t replace exercise and a healthy diet. They act as supplements to complement your healthy lifestyle. Also, for maximum effects, choose products with multiple probiotic strains.

How to Find the Best Probiotic Supplements?

The efficacy of probiotics for weight loss, or any other health effect for that matter, also depends on the supplement you buy. Despite the fact that one can get probiotics through diet, people who don’t like the sources of the good bacteria or don’t consume them in sufficient amounts can benefit from dietary supplements.

That is why it is crucial to know how to find an ideal product. Here are some things to take into consideration:

Quality manufacturing by a reputable brand

This is the number one rule when purchasing supplements, regardless of the type. Always make sure you buy products made by a reliable manufacturer. If the brand is unknown, take some time to do a little bit of research and see whether it is a company you can trust.

Read the label

When it comes to probiotic supplements, the label should always include the following:

  • Genus, species, and strain of the microorganisms e.g. Lactobacillus gasseri SBT2055. As mentioned already, you’ll experience more benefits if you opt for supplements with multiple strains
  • Number of organisms present in a single dose
  • Dosage instructions
  • Storage information when relevant
  • The Expiration date, this is important because it indicates the living microorganisms are still living
  • Certification of an independent third party testing, because FDA does not regulate most supplements, but you still have to make sure the product contains everything it mentions on the label
  • Encapsulated pills or some other technology that ensures bacteria will survive the trip through the acidic stomach and reach the colon

Money-back Guarantee

If the manufacturer does not provide a money-back guarantee, then move on to the next one. You should be able to get a refund if the supplement you buy does not work.

Since then, these live microorganisms have become a subject of multiple studies as scientists wanted to shed some light on their effects and benefits. A growing body of evidence confirms that probiotics are excellent for healthy digestion, the immune system, skin health, and weight loss. In fact, numerous studies have confirmed that probiotics can help you lose weight and burn fat. You can ingest probiotics from yogurts and some cheeses, supplements, and fermented foods that are particularly abundant in Lactobacillus gasseri.
