All Soda's and Diet drinks promote heart problems, and that animals fed artificial sweeteners develop a disrupted metabolic response to real sugar. Like diabetics, they become hyperglycemic. Their blood sugars go up higher than they should.
They also make less of a heart-protective protein. If drinking diet soda interferes with this system, then over the long term you are taking something away that protects your cardiovascular health, and that could be what's contributing to these effects.
Any study that the Soda industry funds and creates the outcome, no matter how damaging to the person's health, it creates media buzz and splashy headlines where the words "science," "study," and "proven weight loss" are favorably combined, and that is worth more than anything a PR firm might cook up; misuse of science to further a preconceived commercial agenda is the norm for today's big food and manmade drink industry.
