One Square meal is made of 2 OSM bars. One Square Meal contains a third (33.33%) of your RDI for all your key nutrients and can replace a meal. So an OSM 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.
