One interesting thing about obesity and bariatric surgery is the changes in the microbiome. The following comes from a study on T2D reversal where bariatric surgery was one aspect of the study: “Furthermore, microbial changes in the human gut have been linked to obesity, and surgical alterations to gastrointestinal anatomy have been associated with dramatic changes in gut microbiota populations with reversion from an “obesogenic” to a lean bacterial population [13,14,16,19,23,24].” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6520897/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6520897/ It’s a relatively new science and area of study but some of it is fascinating if not hopeful. One in particular looked at identical twins where only 1 suffered from malnutrition finding in all such cases the microbiomes were different between the twins and the malnutrition was successfully treated via the microbiome.
