I feel like the people who pay absolutely no attention to their bodies/physical needs and just shove whatever convenience/junk food is available in their face constantly, do need studies to tell them this (so exactly the people who would benefit from the info).  There are a lot of fucking dumb people who need very straight-forward info shoved in their faces for so long, in so many different ways, before they'll at least stop believing the shit excuses they give. I mean fuck, how many years did it take for the general public to believe smoking cigarettes was bad for you? Now you have all these "HAES! I'm big cuz of muh gentetics and I don't understand genetics so there's nothing you I do about that so I'm just going to give up and eat mcdonalds erry day because all that effects is my weight and that's predetermined anyways" idiots.
