What is the difference between an OSM and a One Square Meal?
One Square Meal is made of two OSM bars. One Square Meal contains a third (33%) of your RDI for all your key nutrients and can replace a meal. Therefore an OSM bar contains a sixth of your RDI (16.665%) and can replace a part of a meal or be eaten at times when your needs are less than a full meal would provide. Regardless of how much you consume each and every bite is nutritionally balanced so there is no more guesswork.
