The 3 Day Diet (http://www.diet-blog.com/15/3-day-diet.php) is a variation of the Military Diet. It is a rival, with a slightly different menu.
On Day 1 dinner it calls for 1 cup of carrots instead of 1/2 banana.
Day 2 breakfast calls for 1 banana instead of 1/2 banana.
Day 2 lunch calls for 2% cottage cheese instead of 4% cottage cheese and 7 crackers instead of 5.
Day 2 dinner calls for 1 banana instead of 1/2 banana.
Day 3 dinner calls for 1 cup carrots, 1 cup cauliflower, 1 cup melon,1/2 cup ice cream and no banana, vs 1/2 banana and 1 cup ice cream.
Other than that, they are the SAME EXACT diet.
I wonder which one came first? Ohh, historical development.
