I am looking for a way to solve the diet problem with integer programming (not with the traditional linear programing), in order to set amount constraints for the food items. Is there a way to do it with excel? If not, is there a software, freeware or shareware, that could do it? I am a clinical dietitian and I don't know much maths. I am only looking for a fast and computerized way to make menus for my clinic. I formulated a linear programming model in excel but I would like to set some constraints for the amounts of the fod items.
