as the world's foremost expert on yogurt bodybuilding protocols, i tell you chobani and its ilk are garbage. these so called "greek yogurts" (chobani, zoi, yoplait, voskos, liberte, etc.) have more fucking sugar than protein, WTF!!!!!
the same goes for pretty much any of the "flavored" versions of the best greek yogurts (fage, greek gods, oikos/stony field farms), but go for the plain version and mix it with something yourself if you don't like the flavor.
oikos (now mostly called stony field farms) is the best, imo, better than fage even. i'm not sure if they offer a full fat or even 2%, but their 0% is hands down the best i've had. for full fat, i prefer greek gods over fage, although it's lower in protein.
if you can find noosa (an australian-made culture, not greek), try mixing a tub of that with 1 cup of 0% oikos or fage... DELICIOUS!!!!!!! noosa on its own is probably the best tasting yogurt i've ever had (and i make a point of trying every new type i see), but nutrient-wise resembles greek gods full fat (i.e. a bit low protein, high high fat). if you mix it with a 0% greek, though, it erases the harsh sour taste and helps round out the macro profile... win/win imo.
