The military diet is a variation of the ever-popular three-day diet, a crash plan of "fill-in-the-blank" foods to eat if you want to lose weight fast.

The meal plans are usually extremely basic and calorie-restrictive, because let's face it, that's how you lose weight.
This high-fat, adequate-protein, low-carb fad diet sends the body into a state of ketosis, in which the body uses stored fat for energy.
