These shakes follow a simple premise, restrict your caloric intake to help you to lose weight. Well that is fine and dandy, although you do start getting tired of drinking shakes twice a day instead of eating any real foods. And the diet snack bars are often too sweet with artificial chemicals for my taste buds. I like to drink just one shake a day for breakfast, since it is my most hectic time of the day. If I do not have breakfast I find I graze all day long. So I take a Creamy milk chocolate shake and down it for my morning meal. I haven't noticed any massive weight loss, however it does give me enough energy to keep me going through my morning and into my afternoon. The taste is surprisingly good for a diet shake, although I do like mixing a little fresh fruit or peanut butter in mine to give me a little variety. Having the shake come from Equate means I don't spend nearly as much money as I would buying the name brand.
