The Relationship Between Gut Microbiome and Weight Loss


The Relationship Between Gut Microbiome and Weight Loss

If you’re one of the 160 million Americans who are overweight, you have probably tried countless diets and exercise to try and lose weight without any lasting results. That’s because you don’t have all the information. One incredibly significant piece of the puzzle is to understand the connection between the gut microbiome and weight loss. 

First, you will look at the effects gut microbiome ecology has on weight loss. Then, you will examine whether or not you can change your gut bacteria to lose weight and explore some common methods people try. After that, you can scan answers to the more frequently asked questions about changes to the gut microbiome for weight loss. 

Now, learn everything you need to know regarding the intimate relationship between your gut microbiome and weight loss potential. 

Here are the Proven Effects of Gut Ecology on Weight Loss

Nearly a decade ago, a team at Cambridge University Press published their findings on gut microbiota in obesity and metabolic disorders. Their work stated that the gut ecosystem has an effect on body weight regulation in several different ways. 

  • Influences metabolic, neuroendocrine and immune functions
  • Regulates gene expression 
  • Improves the ability to extract and store energy from food

Their study also declared that gut microbiota imbalances are responsible in part for inflammation, insulin resistance, and weight gain. The correlation between your gut microbiome and weight loss is indisputable yet complex.

Which Gut Bacteria Cause Weight Loss? 

Which Gut Bacteria Cause Weight Loss?

In the Cambridge findings, correlations between obesity and certain levels of specific types of bacteria were identified. For example, an abundance of firmicutes like eubacterium dolichum, halomonas, and sphingomonas were found in obese test subjects. The same study found reduced bacteroidetes and bifidobacterium and high proportions of archaea comparatively in subjects that were overweight.  

Another valuable conclusion from the Cambridge study mentioned above is that reduced bacterial diversity in the gut flora has a direct correlation with obesity. So, when your gut microbiome is made up of fewer families of bacteria, it can have a high impact on weight gain. And, the type of gut bacteria that cause weight loss is not a black and white issue. 

And, Can You Change Your Gut Bacteria to Lose Weight? 

Of course, since food has an effect on your gut microbiome, you can take control of your health through diet. As you already know, making long-term changes the foods you eat is easier said than done (but, probably not for the reasons you think). 

Your gut flora is multifaceted and unique to you. So, gut bacteria obesity treatment must be individualized. The truth about obesity is that it has a variety of contributing factors including an imbalanced gut microbiome. But, there are general changes you can make to alter your gut microbiome. 

Is There an Effective Microbiome Diet?

Eating right can help you lose weight and even manage the negative effects of stress. But, as with everything related to weight loss, there is no one-size-fits-all approach to an efficient diet. Nevertheless, when you educate yourself about genetic predisposition, nutrition, and gut health, you can empower your eating habits.

The best diet approach is to determine which foods are best for you based on your DNA and your unique gut microbiome.

Gut Microbiome and Weight Loss FAQs

Here’s what most people struggling with obesity and being overweight want to know about their gut health and weight loss. 

1. How do gut bacteria affect your weight? 

An overabundance of harmful “bad” bacteria, too few beneficial “good” bacteria, and a lack of microbial diversity can contribute to unhealthy weight gain and obesity. Balanced gut flora can contribute to weight loss. 

2. Can bacterial overgrowth cause weight gain? 

An abundance of “bad” bacteria like firmicutes like eubacterium dolichum, halomonas, and sphingomonas correspond with unwanted weight gain. Other factors like too few “good” bacteria and a lack of microbial diversity also correlate with obesity. 

3. How do I get a healthy gut biome? 

The first step to facilitate a healthy gut microbiome is to gain a clear picture of your current microbiota. Every individual has a unique balance of bacteria in their body, so a sample from your gut can help you come up with a customized and effective plan to improve your health. 

4. How many good bacteria are in the gut? 

The balance of beneficial and harmful bacteria in the gut varies from person to person. But, you have up to 1 trillion bacteria in your gut that are made up of 300 to 500 different species. 

5. Can probiotics help you lose weight? 

Probiotics themselves will not induce weight loss. However, effectively rebalancing the gut flora will have an impact on your ability to lose weight. And, when used properly in conjunction with the right prebiotics, and at the right stage of the healing process, probiotics can help rebalance the gut microbiome. 

6. Can antibiotics make you put on weight? 

Antibiotics themselves will not cause you to gain weight. But, they are known to wipe out many of the beneficial bacteria from your digestive system. And, an imbalanced gut microbiome can contribute to excess body weight. 

Final Thoughts

Now, you understand that gut microbiome and weight loss have a direct correlation. And, you see that there is no single diet plan that will deliver the lasting results you need. But, with a look inside your gut, you can create a customized and lasting plan to heal and to lose weight.
