Probiotics And Keto: Weight Loss Superfriends?

Probiotics are live microorganisms that can be found in fermented foods like yogurt or taken as supplements. They are often referred to as good bacteria and are necessary for breaking down food and supporting a healthy immune system. Probiotics have been linked to improved gut health, better mental health, improved energy levels, and weight loss. While on the keto diet, it is important to maintain a healthy gut, as poor gut health can slow weight loss and negatively impact energy levels. By incorporating fermented foods like sauerkraut, kimchi, and yogurt into your diet, you can improve your gut health and support your weight loss journey. Additionally, probiotic supplements can be beneficial if you are concerned about getting enough probiotics through food sources alone.

Probiotics and weight loss

Probiotics are "good" bacteria that support both cognitive and physical health. They are living microorganisms that occur naturally in the body and promote the growth of healthy bacteria that aid in intestinal and digestive health. Probiotics can be consumed through supplements or fermented foods like yogurt, kimchi, and sauerkraut.

Probiotics and the Keto Diet

Probiotics can be particularly beneficial for those following a keto diet, as this diet can negatively impact gut health. The keto diet is a very strict low-carb, high-fat diet that aims to send the body into a state of 'ketosis', where fat is used for fuel instead of carbohydrates. While the keto diet is popular for weight loss, it can lead to digestive issues such as constipation, nausea, bloating, gas, abdominal pain, and diarrhoea. Probiotics can help mitigate these issues and support overall gut health.

Research suggests that probiotics may aid in weight loss by inhibiting the absorption of dietary fat, reducing inflammation, and increasing the amount of fat excreted in feces. Probiotics may also affect hormones and proteins related to appetite and fat storage, leading to reduced calorie absorption from food.

One clinical trial showed that people with large amounts of visceral fat were able to lose some of this fat after consuming 200 grams of probiotic-containing fermented milk daily for 3 months. Additionally, a 2021 review of several studies found that individuals with moderate weight had different gut bacteria compared to those who were overweight or obese.

However, it is important to note that the impact of probiotics on weight loss is still not fully understood. Some studies have found conflicting results, and researchers are still unclear about which strains of probiotics are most effective for weight loss.

Precautions and Recommendations

While probiotics are generally safe, there are some risks associated with taking them. Probiotics are not rigorously tested like medications, so there may be concerns about the quality and accuracy of labelling. Additionally, as bacteria are living organisms, improper production, storage, or proximity to the expiration date may render them ineffective.

It is recommended to prioritise food-based sources of probiotics, such as fermented foods, over supplements. A well-rounded keto diet should also include nutrient-dense foods and digestive enzymes to support the proper digestion and absorption of fats.

In conclusion, while probiotics may support weight loss, their effectiveness can vary depending on various factors, including the specific probiotic strain, duration of use, and individual starting weight. More research is needed to fully understand the relationship between probiotics and weight loss.

Gut bacteria and body weight regulation

The human body contains trillions of bacteria, most of which are located in the intestines and are collectively known as the gut microbiota. These bacteria play a crucial role in maintaining health by aiding in digestion, producing certain vitamins, and communicating with the immune system. Additionally, they can influence weight regulation by affecting how food is digested and absorbed in the body.

The Link Between Gut Bacteria and Weight

Research has found a connection between the types of bacteria in the gut and body weight. Obese individuals tend to have a less diverse gut microbiome compared to those with a moderate weight. Specifically, obese individuals have higher levels of Firmicutes and lower levels of Bacteroidetes, two of the main families of good bacteria in the gut. This imbalance in the Bacteroidetes-to-Firmicutes ratio is associated with increased inflammation and extraction of energy from food, leading to elevated blood sugar and fat levels.

The Role of Gut Bacteria in Metabolism

Gut bacteria can influence metabolism by producing short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate. These SCFAs are signalling molecules that can affect food intake and metabolism. They bind to receptors on the cells of the gut lining, helping to regulate fat storage and control appetite by inducing the release of appetite-suppressing hormones such as peptide YY and GLP-1. Additionally, SCFAs may increase levels of fat-regulating proteins like angiopoietin-like 4 (ANGPTL4), leading to decreased fat storage.

The Impact of Diet on Gut Bacteria

The food we eat can significantly influence the composition of our gut bacteria. A diet high in refined sugars and unhealthy fats can reduce the diversity of the gut microbiome and encourage the growth of less beneficial bacteria. In contrast, a diet rich in whole plant foods like vegetables, fruits, seeds, nuts, grains, and legumes nourishes beneficial bacteria, promoting a healthy gut lining and a balanced microbiome. These foods contain fibre, which beneficial bacteria use to produce SCFAs and other beneficial metabolites.

Probiotics and Weight Loss

Probiotics are live microorganisms that can be found in fermented foods or taken as supplements. While they are known to have various health benefits, their impact on weight loss is still not fully understood. Some studies suggest that certain strains of probiotics may aid in weight loss by inhibiting fat absorption and reducing inflammation. However, other studies have found conflicting results, and more research is needed to determine the specific strains and mechanisms involved.

Probiotics and the keto diet

Probiotics are "good" bacteria that support both cognitive and physical health. They are living microorganisms that occur naturally in the body and promote the growth of healthy bacteria that aid in intestinal and digestive health. They can also be found in fermented foods like yoghurt or taken as supplements.

The keto diet is a very strict low-carb diet that aims to send the body into a state of 'ketosis', where fat is used for fuel instead of carbohydrates. This is achieved by eating less than 20g of carbohydrates a day for several days in a row.

Probiotics and weight loss

Probiotics are said to prevent the absorption of fat and instead discard it within the body's fecal matter, rather than storing it as body fat. They also help you feel fuller for longer, as well as burning more calories and storing less fat.

Some studies have found that certain strains of probiotics may be linked to weight loss. For example, a 2021 review found that people with obesity had less diverse gut bacteria compared to those who were a moderate weight. Another study found that certain strains of the Lactobacillus family can help with weight loss and belly fat, in combination with exercise.

However, other studies have found no connection between bacteria and weight. While probiotics can have a positive impact on metabolism, it is still unclear how or if they can help with weight loss.

Probiotics can be beneficial on the keto diet, but it requires careful planning. Many sources of probiotics, such as kefir and yoghurt, are carb-heavy, which can be a dilemma for those following a ketogenic diet.

However, there are other keto-friendly sources of probiotics, such as fermented foods like kimchi, sauerkraut, and pickles. It is important to choose unpasteurised or raw options, as pasteurisation destroys the beneficial bacteria.

In addition, a keto diet can improve gut health, but only if the necessary steps are taken. It is important to ensure the diet is abundant in nutrient-dense foods and digestive enzymes, which will allow the body to properly digest and absorb fats.

Precautions

While probiotics are generally safe, there are some risks associated with taking them. As they are not rigorously tested like medicines, the quality of the product can vary, and it is hard to tell exactly what you are getting. In addition, bacteria are living organisms, so if the product is not made, stored, or transported correctly, they may not survive long enough to have any beneficial effect.

It is also important to speak to a doctor before taking probiotics, especially for those with compromised immune systems or severe diseases, as there is a risk of getting sick from taking them.

Probiotics and metabolism

Probiotics are live microorganisms that naturally exist in the body and promote the growth of healthy bacteria that aid in intestinal and digestive health. They are found in fermented foods like yoghurt or can be taken as supplements.

Probiotics have been shown to influence metabolism by helping the body:

• Make folate (vitamin B9)
• Make biotin (vitamin B7)
• Break down carbohydrates
• Make short-chain fatty acids

Probiotics may also help with weight loss by:

• Preventing the absorption of fat
• Increasing feelings of fullness
• Helping burn more calories
• Reducing abdominal bloat
• Lowering cholesterol
• Reducing waist circumference

Probiotics have been shown to have a positive effect on weight loss, especially belly fat, in both animal and human studies. However, more research is needed to fully understand the link between probiotics and weight loss.

Probiotics and appetite

Probiotics are live microorganisms that occur naturally in fermented foods like yogurt or can be taken in supplement form. They promote the growth of healthy bacteria that aid in intestinal and digestive health.

Research has shown that gut bacteria may affect body weight regulation. Experiments in mice and rats suggest that certain microbes living in the gut as part of the gut microbiome have ways of letting the brain know when they have received enough nutrients to reach their goal—creating a billion more of their kind. Those signals seem to turn hunger on and off in their hosts.

The gut bacteria can influence the hormones the gut produces, which then send signals to the brain to either eat more or stop eating. The gut bacteria can also influence the gut-brain axis, which is the connection between the gastrointestinal tract and the central nervous system.

Probiotics can help regulate how food is processed, which is important for long-term weight loss. Research has shown that taking a probiotic supplement can lead to reduced absorption of fat in food, which means the body will "harvest" fewer calories and ultimately lose more weight while eating the same foods.

Probiotics can also influence the levels of hormones and proteins related to appetite and fat storage. For example, probiotics may increase levels of the protein angiopoietin-like 4 (ANGPTL4), which is associated with decreased fat storage. Probiotics may also increase levels of the appetite-reducing hormones glucagon-like peptide-1 (GLP-1) and peptide YY (PYY).

Additionally, probiotics may reduce systemic inflammation, which can protect against obesity and other diseases. A healthy gut ecosystem contributes to lowering LDL ("bad") cholesterol and blood pressure, which may lead to a reduced risk of heart disease.

While there is evidence that probiotics can help regulate appetite and make it easier to lose weight, more research is needed to fully understand the role of bacteria in weight loss.
