It seems like every reality star is on this diet! After seeing Real Housewives Kim Zolciak Biermann and Porsha Williams' Instagram about their secret to keeping their super tiny waists even after indulging in their favorite holiday treats, we had to see what the buzz was about. Turns out all the reality stars are posting about the same diet regimen and if these pictures are any indication of what these products can do, we have to get our hands on these miracle shakes taking over Hollywood. Look through this gallery to see the stars that have turned to 310 Nutrition to drop the pounds and get rid of that extra layer of fat the healthy way.
