I really enjoyed the Slimfast plan it gave me the flexibility to chose meals to prepare on my own and the option of using one of their products or snack for on the go or if you have little time to prepare a meal.The plan works of course with exercise but nevertheless it works.I lost over 77 lbs on the plan 79 to be exact so I would recommend this plan to anyone trying to lose weight. They even have a website,online chats, a buddy system, and customer support as a free service; all of which you can take advantage of even if you have never tried their products.
