    is likely incorrect.
    The medical community has been trying to argue this for 30 years, but this beastie is more associated with cancers than digestion. All bacteria are NOT our friends.  In fact bacteria and viruses are the cause of death for MOST of the population before the advent of public water treatment and antibiotics.

    As to the reduction of bacterial species, bacteria really do not HAVE fixed species in the way that we think about them.  Bacteria have loops of DNA within the cell membrane called plasmids. When bacteria come under stress they grow sexual pilli and free start swapping plasmids with whatever other bacteria of whatever species are around, plus bacteria that grow in biofilms (consortia of bacteria in an ordered goo (EPS)  they create) expel DNA into the biofilm.
     90% + of bacteria live in multispecies  biofilms and these biofilms are antibiotic resistant, like 1000 times more antibiotic resistant than free swimming bacteria.

    So NO the increase in obesity that we are seeing is NOT likely the result of killing off bacteria.

      . It is more likely the result of our not really moving very much compared to the -physical labor that was required just a century ago.

      Also we are breeding cattle to gain the maximum amount of weight in the shortest period of time.  Which very likely means we are breeding the biome of the cattle to most efficiently break down fodder into components that can be digested by the cow. The biome's of obese people may be  characterized by similarly highly efficient biomes.

      As for type 1 and type 2 diabetes, Diabetes has been shown to go into remission in some cases when  gum disease is addressed, therefore I believe we will find that at least some diabetes is bacterially caused, probably by a bacterial biofilm.
