Military Diet Food Substitutions: Every Approved Swap for Every Food

The Golden Rule of Military Diet Substitutions

Any food on the military diet meal plan can be substituted with another food, provided the substitute contains the same number of calories as the original item. Calorie equivalence is the only rule that matters for substitutions — you do not need to match protein, fat, or carbohydrate content, though staying within the same food category (protein for protein, fruit for fruit) is a helpful guideline.

For example, if the meal plan calls for half a cup of canned tuna at approximately 90 calories, you can replace it with any food that provides approximately 90 calories. That could be cottage cheese, tofu, almonds, or any other food you prefer.
