Hi,
At the risk of being out of place because I am a woman in the men's corner

, here's my humble opinion...
I used to drink a lot of meal replacement shakes, not this brand but a different one called Medifast at the recommendation of a doctor. Some of the shakes tasted better than others, most were quite filling but also expensive financially and I was replacing two meals a day with the shakes. I eventually ditched the plan because I craved real food. I did lose some weight with Medifast and I gained some of it back. I personally think it is more important to eat nutritiously. It did help me get rid of some pounds and for some people it can work great but everyone is different.
Good luck!
