Can Gut Bacteria Can Help Make Us Fat or Thin?

how gut bacteria can impact weight loss or weight gain

Research in America shows 35% of all American are obese.

The emphasis on weight loss and weight gain has started to rise over the years. With sedentary lifestyles, poor dietary habits, and an unwillingness to understand the science behind body weight, it’s become necessary to dissect the subject in detail.

This is where the topic of “gut bacteria” and its importance comes into the picture. Here is a look at how gut bacteria help make people fat or thin.

The Impact of Gut Bacteria

Let’s start with the basics.

Gut bacteria is seen as a role player in managing weight. Researchers have found gut bacteria has an impact on how the body stores fat.

This begins from an early age and continues to dictate how the body retains fat and how fast the body eliminates fat.

It dictates the following aspects of the human body:

  1. Blood Glucose Levels
  2. Body’s Response to Dietary Changes
  3. Feeling of Fullness
  4. Storage of Fat

As you can imagine, this has a significant impact on how the body registers fat storage and how the body looks when you step on a scale.

This information can help steer people in the right direction while appropriately managing their weight.

Why Study Gut Bacteria?

Why Researchers are Spending Time on This…

The premise is to get to the root of the problem (i.e. obesity). Is there a way to control the body’s internal settings to help manage weight gain or weight loss?

This is why gut bacteria provide an intriguing angle to this field of study. In general, gut bacteria have a robust impact on how the body manages weight and researchers want to learn how to control it.

If they can distinguish good bacteria, it will become easier to manage weight and help optimize the body so it can head in the right direction.

Recent Results

What have scientists learned in recent years while dissecting gut bacteria?

Scientists have learned a lot, and that’s what makes gut bacteria such an interesting topic of discussion. They have learned a majority of the bacteria is formed and housed in your intestines. The bacteria also outnumber the average cell at a 10:1 ratio.

Studies show the initial bacteria a human body is exposed to comes from his/her mother’s body.

After birth, the microbes are built from what’s consumed and the environment around a child. This is why it has become important to get a grasp of how these microbes enter the body and how they can be micromanaged for better results.

Diversity of Microbes

This is the biggest discovery for scientists who have spent time researching gut bacteria.

They have noticed leaner individuals tend to have a distinct profile with their gut bacteria.

This means the gut bacteria have a wider range of Bacteroides, which help process fat and make sure all components are running in a well-oiled manner.

However, those who are prone to gaining weight and might be battling with obesity don’t have a diverse profile of Bacteroides. Instead, they have a reduced version that is restricted.

Scientists believe appropriate changes whether they’re dietary, environmental, or supplemental can do wonders for those who are on the wrong end of the spectrum.

They have started to work on creating this diversity for those who are not born with it.

Continuous work is done on this to learn how gut bacteria break down and researchers have spent time maximizing the information in front of them.

This is why they have looked at dietary changes as those are the easiest to implement.

Dietary Requirements

Scientists have realized a good diet can help with the diversification of Bacteroides.

Anyone consuming processed foods on a daily basis will be ruining their chances of remaining fat-free. The diversification will slow down, and that’s where obesity kicks into high gear.

Those who can eliminate processed foods increase the likelihood of optimizing their gut bacteria.

Studies also revealed mice with an obese-centric profile were not as efficient at processing foods high in fat. Their bodies packed on weight and didn’t shed it as quickly because of the gut bacteria.

While those who had a lean-centric profile did a better job with the same food.

Formula-Fed Babies At Greater Risk

Yes, those who have been formula fed at a young age are prone to have an inferior profile of Bacteroides.

This is why it is important to keep tabs on the baby’s diet and making sure they’re in a safe environment. It can have a significant impact on their health and how the body digests food.

Can Supplements Help Improve Gut Health?

If you feel like you need to get your bacteria back on track, the first thing you will want to do is to consult with your doctor to come up with a plan of action.

If they suggest trying supplements or probiotics, there are some brands out there that I prefer, but you’re free to go with whichever company you like.

You can also find some great probiotic options at your local health food store, so be sure to check that out too if you prefer buying in person.

Onnit Labs Total Gut Health

I, for one, like buying stuff online, and when it comes to buying supplements, Onnit is my recommended resource (see why).

When it comes to probiotics, they have an awesome product called Total Gut Health. Here’s what you can expect if you buy it:

  • Everything You Need to Optimize Gut Health
  • Digestive Enzymes
  • Prebiotics
  • Probiotics
  • Betaine HCI

This is just one option worth considering, but of course there are dozens more about there, so dig around a bit if you don’t thing Onnit Total Gut Health is the right supplement for your gut issues.


Scientists plan to continue their research to learn how to optimize gut bacteria and bring it under their control.

From what we know now, though, gut health can have a big impact on your overall health as well. In fact, recent studies suggest that your gut biome may serve as the foundation for a strong immune system, along with primed brain function.

For these reasons, it’s important to take gut health seriously.
