It's a lifestyle, the optimal basic lifestyle, the one were you don't shorten your life/healthspan by decades. It's how thing were intended to be really.
It's funny how proposing an healthy diet is unrealistic and watching fatties eat themselves to death is the new normal, complete value inversion and looser mentality
you don’t seem amused so much as annoyed.
perhaps you can elaborate on how systemic death spirals are funny?
Lifestyle changes are essentially standard medical advice. There is nothing wrong with proposing diet and exercise.
It's just that you should probably suggest other treatments in addition to the lifestyle changes that have relatively low long term efficacy.
Of course, that assumes your goal is to actually help the fatties instead of judging them.
