How Probiotics Can Help You Lose Belly Fat
Some probiotic strains may help support weight loss and provide other health benefits, including to your heart, immune system, and digestive system.
Probiotics are live microorganisms that have health benefits when eaten. They’re found in both supplements and fermented foods.
Researchers have found that probiotics may improve your immune function and digestive and heart health, among other benefits.
Studies also suggest that probiotics can help you lose weight and belly fat.
Hundreds of microorganisms reside in your digestive system.
According to
There are two main families of good bacteria in the gut: bacteroidetes and firmicutes. Research has found that body weight seems to be related to the balance of these two families of bacteria.
One 2021 review of several studies found that moderate-weight people have different gut bacteria than those with overweight or obesity, but more research is needed.
In the some of those studies, people with obesity had more firmicutes and fewer bacteroidetes, compared with moderate-weight people. The review found that people with obesity tend to have less diverse gut bacteria than lean people.
Summary
Studies suggest that gut bacteria may play a powerful role in body weight regulation.
According to research, probiotics seem to influence appetite and energy usage via the production of acetate, propionate, and butyrate, which are short-chain fatty acids.
Studies have found that certain probiotics may inhibit the absorption of dietary fat, decreasing inflammation and increasing the amount of fat excreted with feces.
In other words, they make your body “harvest” fewer calories from the foods you eat. Certain bacteria, such as those from the Lactobacillus family, have been found to function in this way.
Probiotics may also fight obesity in other ways, including:
- Releasing appetite-regulating hormones: According to
research , probiotics may help release the appetite-reducing hormones glucagon-like peptide-1 (GLP-1) and peptide YY (PYY). Increased levels of these hormones may help you burn calories and fat. - Increasing levels of fat-regulating proteins:
Research has also found that probiotics may increase levels of the protein angiopoietin-like 4 (ANGPTL4). This may lead to decreased fat storage.
By improving the health of your gut lining, studies have found that probiotics may reduce systemic inflammation and protect against obesity and other diseases.
Summary
Probiotics may reduce the number of calories you absorb from food. They also affect levels of hormones and proteins related to appetite and fat storage, as well as potentially reduce inflammation, which can drive obesity.
A recent review of studies on probiotics and weight loss in people with overweight and obesity suggests that probiotics may help you lose weight and lower your body fat percentage. However, more research is needed.
In particular, studies have found that certain strains of the Lactobacillus family can help you lose weight and belly fat combined with exercise.
In one study, consuming products with Lactobacillus curvatus and Lactobacillus plantarum displayed a reduction in body weight, visceral fat mass, and waist circumference.
In another
Lactobacillus gasseri
Researchers have found that Lactobacillus gasseri shows promising effects on weight loss in humans.
The meta study found that Lactobacillus gasseri decreased body weight, BMI, waist circumference, body fat mass or fat percentage in those with overweight or obesity. It also decreased visceral fat.
What’s more, it still showed weight loss effects even when the participants did not undergo energy restriction. However, more research is needed.
Other strains
Other strains of probiotics may also help reduce weight and belly fat.
In an 6-month
Those consuming the probiotic lost more weight than those taking a placebo.
One 2020 study found that Bifidobacterium animalis subsp. lactis had a positive effect on weight management and reduced inflammation.
Summary
Several strains of probiotics in both the Lactobacillus and Bifidobacterium family have been shown to reduce weight.
Losing weight is not the only way to fight obesity. Preventing unwanted weight gain in the first place may be even more valuable in avoiding obesity.
In one
This indicates that some probiotic strains might have the same effect in humans. However, this needs to be studied further.
Summary
Certain probiotic strains, such as VSL#3, may be able to reduce weight gain. However, more research is needed.
Probiotics offer a wide range of health benefits.
Evidence indicates that Lactobacillus gasseri may help people with obesity lose weight and waist circumference. Additionally, a probiotic supplement blend called VSL#3 may also reduce weight gain, but more research is needed.
At the end of the day, certain types of probiotics may have modest effects on your weight, especially when combined with a healthy, whole-foods diet.
However, there are many other reasons to take a probiotic supplement. They can improve your digestive health and cardiovascular risk factors, as well as reduce inflammation.
