There goes the medical community. 

 That's an easy one... I'd have to go back 40 years to find a doctor that gave me nutrition advice...  Or anything other than prescription for that matter. 

 Why stop at nutrition advice? 

 Never let me dictate the rights of women’s bodies!!! 

 That is good advice.  

 My daughter was feeling quite under par for a few weeks. So we went to the doctors. I was assuming they would prescribe some medicine or something. Inside we had this young fit doctor. He asked what she ate and then said she needed more red meat in her diet. Well I was totally shocked and heartened to hear this from a doctor. I guess change can happen 

 to be fair most doctors aren't fat.

most patients are though, regardless of what they're in for.

even mental health patients are fat ( the ones that aren't junkies or anorexics ).

obesity is basically an outward manifestation of ignorance, stupidity and poor impulse control which then has downstream effects like Diabetes and then further down Heart Disease and other conditions.

i will rephrase what you said in more general terms - NEVER TAKE ADVICE FROM A FAT PERSON. 

 unless his advice is " never allow yourself to get as fat as me,  you will regret it "

then take the advice !
