I am over 250 pounds past my ideal weight. I am going to try having 2 meal replacement shakes a day out of my 5 meals a day. I plan on exercising for 30 to 45 minutes everyday, eating healthy, and drinking plenty of water. I have 4 brands in mind: Body By Vi, BioTrust, Shakeology, or IdealShape. WHICH ONE DO YOU THINK IS BEST FOR ME? Do you have a brand for recommendation?
