Belly fat is extremely unhealthy. In fact, it increases the threat of heart illness, kind 2 diabetes and other wellness circumstances (1).
Luckily, belly fat can be lost, and current analysis shows that a higher fiber intake is linked to a lower risk of belly fat (two).
But interestingly, it appears that this consists of only one particular type of fiber — soluble fiber. This post explains how soluble fiber can support you shed belly fat.
Soluble Fiber Can Assist You Drop Belly Fat
There are two varieties of fiber — insoluble and soluble fiber. They differ in how they interact with water in your physique.
Insoluble fiber does not mix with water and acts mainly as a bulking agent to aid type stool and pass it by way of the gut. This can assist with constipation (3).
Soluble fiber, such as beta-glucan, psyllium husk and glucomannan, mixes with water to kind a viscous, gel-like substance that slows down how rapidly the stomach releases digested food into the gut (four).
This gives nutrients and water more make contact with time with the walls of the gut, top to much better absorption.
Consuming a lot more soluble fiber can also aid you lose belly fat and stop belly fat gain. A single study linked a ten-gram boost in every day soluble fiber intake to a three.7% reduced threat of gaining belly fat (two).
Several other studies also show that people who consume much more soluble fiber have a reduced threat of belly fat (five, 6).
In truth, soluble fiber may possibly help decrease belly fat in several techniques.
Summary: Soluble fiber differs from insoluble fiber in how it interacts with water and other locations of the body. Soluble fiber could help reduce belly fat.

Humans give the bacteria with a home and nutrients, although the bacteria aid take care of processes like making vitamins and processing waste (7).
There are a lot of distinct kinds of bacteria, and possessing a higher variety of gut bacteria is linked to a lower risk of circumstances like type 2 diabetes, insulin resistance and heart disease, to name a few (8).
And despite the fact that it is not clear why, several research show that men and women who consume much more soluble fiber have a greater assortment of bacteria and much better well being outcomes (9, 10, 11, 12, 13).
What’s more, a recent study showed that folks with a higher range of gut bacteria have a reduced danger of belly fat (14).
Whilst initial investigation on bacterial diversity’s effect on belly fat is promising, much more research are required before a clear link can be produced.
Summary: A greater range of beneficial gut bacteria could be linked to a reduced danger of belly fat, but far more study is required to confirm this.
How Beneficial Gut Bacteria Could Minimize Belly Fat
Because your body can not digest fiber itself, it reaches the gut largely unchanged.
As soon as there, certain enzymes in gut bacteria can digest soluble fiber. This is 1 important way in which gut bacteria market optimal wellness. Meanwhile, soluble fiber acts as a prebiotic, providing the bacteria with nutrients.
This procedure of digesting and processing soluble fiber is known as fermentation. It produces short-chain fatty acids, a type of fat that can aid reduce belly fat.
One particular way brief-chain fatty acids may support regulate your fat metabolism is by growing the rate of fat burning or decreasing the rate of fat storage, despite the fact that precisely how this works is not totally understood (15).
Regardless, several studies show a connection among a higher level of brief-chain fatty acids and a reduced danger of belly fat (16, 17, 18, 19).
Additionally, animal and lab research have shown that short-chain fatty acids have reduced the threat of colon cancer (20).
Summary: Your gut bacteria can digest soluble fiber. The procedure produces quick-chain fatty acids, which are linked to a reduce threat of belly fat.

Others have shown that soluble fiber increases the production of hormones that make you really feel complete, such as cholecystokinin, GLP-1 and peptide YY (25, 26).
Second, fiber can decrease appetite by slowing the movement of food by way of the gut.
When nutrients like glucose are released gradually into the gut, your physique releases insulin at a slower rate. This is linked to a decreased sense of hunger (4).

But if this is not realistic for you, taking a soluble fiber supplement could be an selection.
Various types are offered, which includes psyllium husk, glucomannan and inulin, and some evidence shows they can assist you lose belly fat.
For example, one six-week study in teenage boys showed that taking a psyllium husk supplement lowered belly fat (28).
Also, the viscous fiber glucomannan has shown mixed results for belly fat loss. One particular study in mice identified that glucomannan supplements reduced belly fat, while a human study showed the same impact, but only in men (29, 30).
But in spite of these mixed results, glucomannan can also market belly fat loss by slowing down digestion and reducing appetite (31).
Inulin is yet another kind of soluble fiber. Even although it is not really viscous, it has been linked to belly fat loss.
One particular 18-week weight loss study in men and women at risk of kind 2 diabetics gave participants either inulin or cellulose (insoluble fiber) supplements. Both groups received nutrition advice for the first nine weeks and followed a fat-loss diet program.
While each groups lost weight, the inulin group lost drastically more belly fat, total physique fat and total weight. They also ate significantly less meals than the cellulose group (32).
General, fiber supplements appear like a promising region for future study in belly fat loss. However, a lot more investigation is required just before generating a stronger recommendation.
Summary: Psyllium, glucomannan and inulin show promise for belly fat loss, although far more analysis is required to make supplement suggestions.
The Bottom Line
