What are meal replacements?
Meal replacements are low calorie meals or snacks that are usually high in protein, and are meant as a replacement for regular meals. Decades ago, meal replacements were usually protein rich drinks and shakes, but thanks to technology, dieters have a wide range of meals to choose from.[quote]A meal replacement drink is one intended as a substitute for a solid food meal, usually for purposes of weight loss. Often such drinks are in the form of a health shake. Medically-prescribed meal replacement drinks, which include required vitamins and minerals, include Optifast and HMR. – Wikipedia[/quote]
