Prebiotics and probiotics are being touted as the ultimate gut-friendly duo, promising to promote digestive health, boost immunity, and aid in weight loss. The research looks good. I started my big belly buster prebiotic and probiotic plan three weeks ago and you know what? I gained weight – big belly weight. Yes, it’s true.
Although, I did read a research article that mentioned evidence of some intestinal weight gain. Honestly, I skimmed that article and didn’t really read it. It was about chickens, and I was more interested in people. However, as I keep gaining weight, I keep remembering that little piece of information.
So, I did a quick search on the internet and some research does suggest that pre and probiotic supplements may contribute to weight gain in some individuals. Well apparently, I am one of them. So, let’s review the unexpected ways in which prebiotics and probiotics can lead to weight gain, and then I’ll tell you what is happening to me.
The Gut-Brain Axis: A Double-Edged Sword
The gut-brain axis is a complex network that connects the gut microbiome to the central nervous system. While a healthy gut microbiome is essential for overall well-being, an imbalance of the gut flora can have far-reaching consequences, including weight gain. The whole idea that “your gut microbiome is making you fat” speaks to this possibility. Probiotics, which introduce beneficial bacteria into the gut, can sometimes disrupt the delicate balance. Apparently, by altering the gut microbiome, with prebiotics you can possibly influence hunger hormones, leading to increased appetite and food cravings.
Prebiotics: Fuel for the Wrong Bacteria
Prebiotics, non-digestible fibers that serve as food for beneficial bacteria, can also have unintended consequences. While they do feed the good bacteria, they can also fuel the growth of opportunistic pathogens, which can contribute to weight gain. For example, certain prebiotic fibers can be fermented by bacteria that produce lipopolysaccharides, which have been linked to inflammation and metabolic dysfunction, leading to weight gain.
Increased Production of Short-Chain Fatty Acids
Both prebiotics and probiotics can increase the production of short-chain fatty acids (SCFAs), which are produced when beneficial bacteria ferment fiber. While SCFAs have been shown to have anti-inflammatory effects, they can also stimulate the production of leptin, a hormone that regulates energy balance. Elevated leptin levels can lead to increased hunger and food intake, ultimately resulting in weight gain.
Changes in Gut Motility and Satiety
Probiotics can alter gut motility, or the movement of food through the digestive system. Slower gut motility can lead to increased absorption of calories, as the body has more time to extract nutrients from food. Additionally, some probiotics can influence the release of gut hormones that regulate satiety, leading to increased food consumption and weight gain.
Bloating and Water Retention
Prebiotics and probiotics can also cause bloating and water retention, leading to weight gain. As the gut microbiome adjusts to the introduction of new bacteria or prebiotic fibers, it’s common to experience temporary bloating and discomfort. This can lead to water retention, which can manifest as weight gain on the scale.
Individual Variability: A Key Factor
It’s essential to note that individual variability plays a significant role in the effects of prebiotics and probiotics on weight gain. Some people may experience weight loss or no change in weight, while others may gain weight due to the factors mentioned above. This variability is likely due to differences in gut microbiome composition, diet, and lifestyle factors.
Thoughts and Possibilities in My Situation
I believe my prebiotic and probiotic supplementation is having an overall positive effect, even though I’m gaining weight in my gut, right where I don’t want to. Why do I think this? It’s because I am seeing some small positive gains. since I started my supplementation. I sleep better most of the time. I do not need to take melatonin, tart cherry juice or any other sleep aid. My appetite has decreased. I am eating less, and I am not hungry. I like both those positive changes and the only thing I don’t like is the weight gain.
So why am I gaining weight. Considering the possibilities above I am going to go with bloating, slow gut motility, some water retention and prebiotics. First let me explain that bloating when using prebiotic is a thing for me. I tried FOS (Fructooligosaccharides) before. FOS is a prebiotic and it bloated me so badly I stopped using it. I take that as evidence. I am someone whose system is off balance and trying to balance it with prebiotics causes bloating. This time I want to continue to supplement and see what lies past the bloat. The next thing could be slow gut motility and water retention. Let’s be clear slow gut motility is a fancy name for constipation and I like it. I am no stranger to slow gut motility and water retention. My body does it all the time so I have to acknowledge it may be part of my weight gain.
Prebiotics: Fuel for the Right Bacteria
I have a theory and a hope, that prebiotics are contributing to my weight gain. I think the prebiotics are fueling my good bacteria and helping to make my body better by improving my intestinal structure. The study on broiler chickens found that supplementing their diets with prebiotics, probiotics, and synbiotics (a combination of prebiotics and probiotics) led to significant improvements in weight gain and feed conversion rate in the broilers [1]. The results also showed that the prebiotics had positive effects on the intestinal structure and function of the broiler chickens [2].
Another poultry study done on turkeys showed that a prebiotic treatment increased the density of goblet cells, the mucous producing cells within the small intestine [3]. You might be thinking, “It’s being used to fatten turkeys, oh heck no!” But the person was trying to see if turkeys could be spared the use of antibiotics. She said, “A higher goblet cell density will create a thicker layer of mucous which protects the body from bad bacteria and provides binding sites for good bacteria.” So it’s not about fattening them up and that’s a good thing.
That’s why I’m going to continue my journey using prebiotic and probiotic supplements. I will keep you posted on my results. While prebiotics and probiotics are generally considered safe and beneficial, they may not be suitable for everyone. It’s crucial to approach these supplements with caution and be aware of the potential risks, including weight gain. If you’re considering adding prebiotics or probiotics to your regimen, consult with a healthcare professional to discuss the potential benefits and risks. Additionally, focus on a balanced diet and healthy lifestyle habits to support overall well-being and weight management.
Remember, a healthy gut microbiome is essential for overall health, but it’s not a guarantee of weight loss. By understanding the potential pitfalls of prebiotics and probiotics, you can make informed decisions about your health and wellness journey.
