The Health Quest Podcast with Dr. Sal.

We've been told to simply eat less and move more, but the pain of constantly battling with your weight and health hasn't subsided. It's time to dig deeper and understand how leaky gut may be the missing link.

So many people try countless diets and exercise routines, yet they still struggle with obesity, autoimmune disorders, or mental health issues. Dr. Sal uncovers the hidden link between leaky gut and weight gain, unveiling a fierce battle raging within our bodies as inflammation fuels obesity and disease.


"Your gut health is the key to reducing inflammation, preventing disease, and achieving overall well-being." - Dr. Sal

Key takeaways:


  • Lipopolysaccharide (LPS) is a component of gram-negative bacteria that enters the bloodstream and triggers an inflammatory response. This can lead to systemic inflammation and various health issues.

  • Post-prandial alkaline tide (PPA), caused by consuming certain foods, compromises mitochondrial function and can have negative effects on the brain's energy usage. Avoiding PPA and taking certain supplements can help counteract these effects.

  • Short-chain fatty acids, produced by gut bacteria from dietary fiber, play a crucial role in maintaining a healthy gut and overall body function. Including high-fiber foods in your diet, such as vegetables and seeds, can help support the production of beneficial short-chain fatty acids.

  • Cell-to-cell signaling is an essential process in the body, allowing cells to communicate and understand what is happening elsewhere. Compromised mitochondrial function can disrupt this communication, emphasizing the importance of keeping mitochondria healthy.

  • Elevated levels of lipopolysaccharides (LPS) in the bloodstream, indicating a leaky gut, can have detrimental effects on various organ systems and contribute to chronic inflammation. Testing for LPS levels can help identify underlying health issues related to leaky gut syndrome.

Timestamped summary:


00:00 - Gram-negative bacteria have both good and bad forms. Lipopolysaccharides are a component of the outer membrane of these bacteria and protect them from digestion. They are an endotoxin and cause an inflammatory response when in the bloodstream. Elevated markers of lipopolysaccharides are found in many conditions.

05:01 - Cytokines cause inflammation in immune system. Local intestinal inflammation linked to bowel diseases. Picture shows disrupted barrier with 4 layers. 08:55 - NF Kappa B leads to inflammation and metabolic endotoxin. Leaky gut allows LPS into bloodstream.

12:40 - Sugar, processed food cause brain inflammation, dementia

14:08 - Short chain fatty acids are created by gut bacteria processing dietary fiber. Eating a high fiber diet is the best way to get these acids. The three main fatty acids produced are acetic, butyric, and propionic. Butyric acid is the primary energy source for colon cells, helping them rebuild every 3 to 7 days.

18:42 - Counteract PPA with supplements and healthy foods.
