The SlimFast Diet Plan

The SlimFast diet is a commercial calorie limiting eating plan which first appeared in the late 1970s. The diet was at first a shake only plan but later incorporated SlimFast bars. The current version was modified in the late 2000s and uses the 3-2-1 format standing for three SlimFast snacks two SlimFast meal replacements and a well-portioned dinner.
