But those numbers undercount the reality, because many people do not report burping as a side effect
Poor Diet and Nutrient Deficiencies: A diet lacking in amino acids like glutamine, cysteine, and glycine can hinder glutathione production
Stepien, Brian A
The answer depends on what you're trying to address
The effect can be prolonged by lower gut bacterial action on fermentable fibers (see below) to produce short-chain fatty acids (propionate, butyrate, etc.) Healthful naturally-occurring animal fats such as tallow, lard, butter, and schmalz, the oils of fatty fish (salmon, mackerel, sardines, trout) and fruit and nut oils (coconut oil, olive oil, avocado oil, macadamia nut oil) activate free fatty acid receptors on Lcells to stimulate the release of GLP-1 from the gut and prolong its activity.There was early research that seemed to indict a diet high in saturated fats (what a surprise) as potentially toxic to the L-cells over time, but all that research was done in isolated cell models or high-fat/high carb rodent diets, not in a ketogenic diet context in humans
