Correct. And as shown by the MH freeze dried meal, it isn't always lighter. In my examples, it was the second heaviest, and about 20% heavier than the food I carry on the trail. Besides, all else equal, there would be no significant difference in weight between freeze dried foods and dehydrated foods. The reason food is freeze dried is so that the consistency of food is not compromised like it can be during regular dehydration. Both processes are meant to dehydrate the food, but in different ways.
